Tech Waste: Environmental Impact and ManagementEditor IJCATR
Over the recent years, the global market of electrical and electronic equipment (EEE) has grown rapidly, while the products
lifespan has become increasingly shorter. The rapid growth of the electronic and IT industry, current user’s culture, increasing rates of
usage of techno products have led to disastrous environmental consequences. Most of these technologies are ending up in backlash
and recycling centres, posing a new environmental challenge in this 21st century. The presence of hazardous and toxic substances in
electronic goods has made tech waste a matter of fear and if not properly managed, it can have unfavourable effects on environment. It
has been proven that some of the waste contain many cancer-causing agents. This paper provides a review of the tech waste problems
and the need for its appropriate management
This document discusses e-waste, which is defined as discarded electrical and electronic equipment. It notes that e-waste is one of the fastest growing waste streams due to high obsolescence rates of electronics. E-waste contains toxic components like lead, cadmium, and mercury if improperly treated or discarded.

This document summarizes an academic paper presented at the International Conference on Emerging Trends in Engineering and Management in 2014. The paper proposes a design and implementation of an elliptic curve scalar multiplier on a field programmable gate array (FPGA) using the Karatsuba algorithm. It aims to reduce hardware complexity by using a polynomial basis representation of finite fields and projective coordinate representation of elliptic curves. Key mathematical concepts like finite fields, point addition, and point doubling that are important to elliptic curve cryptography are also discussed at a high level.
1. The document describes a five-level cascaded H-bridge inverter used as a distribution static compensator (DSTATCOM) to compensate for reactive power and harmonics in a power system.
2. A DSTATCOM is connected in shunt with the distribution system and uses a voltage source converter to generate a set of three-phase output voltages that can be adjusted to control the exchange of active and reactive power with the system.
3. The five-level cascaded H-bridge inverter topology reduces device voltage stress and output harmonics. Level shifted pulse width modulation and phase shifted pulse width modulation techniques are investigated for controlling the DSTATCOM.
Efficient implementation of bit parallel finite eSAT Journals
Abstract Arithmetic in Finite/Galois field is a major aspect for many applications such as error correcting code and cryptography. Addition and multiplication are the two basic operations in the finite field GF (2m).The finite field multiplication is the most resource and time consuming operation. In this paper the complexity (space) analysis and efficient FPGA implementation of bit parallel Karatsuba Multiplier over GF (2m) is presented. This is especially interesting for high performance systems because of its carry free property. To reduce the complexity of Classical Multiplier, multiplier with less complexity over GF (2m) based on Karatsuba Multiplier is used. The LUT complexity is evaluated on FPGA by using Xilinx ISE 8.1i.Furthermore,the experimental results on FPGAs for bit parallel Karatsuba Multiplier and Classical Multiplier were shown and the comparison table is provided. To the best of our knowledge, the bit parallel karatsuba multiplier consumes least resources among the known FPGA implementation. Keywords: Classical Multiplier, Cryptograph, FPGA, Galois field, Karatsuba Multiplier

IRJET- E-Waste Bin a Solution for E-Waste Collection in IndiaIRJET Journal
1) India is the 5th largest producer of e-waste in the world, producing 3 million tons annually and growing at 20% per year. However, only 1-2% is properly disposed of.
2) The authors developed an "e-waste bin" prototype to help collect e-waste for proper treatment. The bin uses fingerprint scanning and rewards users with points for depositing e-waste.
3) The bin has compartments for small and large e-waste. Users select the size, deposit the waste, and get points added to their profile in an associated database. This aims to increase e-waste collection and safe disposal.
E-waste, or electronic waste, refers to discarded electrical or electronic devices. It is the world's fastest growing waste stream and poses environmental and health risks if not disposed of properly. The amount of e-waste in India is rapidly increasing as industries like IT and telecommunications grow and consumers replace electronics more frequently. Improper recycling of e-waste can release toxic chemicals like lead, beryllium, and mercury into the environment and harm workers who dismantle devices without protection. There is a need for better e-waste collection systems and management in India to deal with rising quantities and reduce environmental pollution and health impacts.
This document discusses e-waste management issues in India. It defines e-waste as old or obsolete electrical and electronic equipment such as computers, mobile phones, televisions, etc. E-waste is growing rapidly due to short life cycles and planned obsolescence of electronic devices. Most e-waste in India is handled by the informal sector using unsafe recycling methods that release toxic substances like lead, cadmium, and mercury into the environment. This poses serious health risks. While e-waste contains recoverable materials, the current practices are inefficient and polluting. The document outlines the responsibilities of producers under India's E-Waste Management Rules and calls for better implementation of regulations to promote formal, safe recycling of e-
E-waste refers to obsolete, broken, or discarded electrical or electronic devices. The document discusses the sources, composition, impacts, and proper disposal of e-waste. It notes that e-waste is one of the fastest growing waste streams and contains hazardous materials like lead, mercury, and cadmium. Improper disposal of e-waste through landfilling or incineration can pollute the environment and harm human health. Recycling e-waste helps reduce these impacts and recover valuable materials. Individual actions like recycling old electronics can help address the growing problem of e-waste.
Electronic Waste impacting Health And Environment, Its Management -Global & I...IJSRED
This document discusses electronic waste (e-waste), its global and Indian perspectives, and the need for proper management. Some key points:
- E-waste is growing exponentially worldwide due to rising electronics use and short product lifecycles. About 50 million tons is generated globally each year.
- Only 20% is recycled properly through formal means. The rest is often handled improperly, contaminating the environment and exposing workers to toxins.
- E-waste contains valuable materials like gold, silver and copper, but also toxic heavy metals like lead, mercury and cadmium. Improper disposal leads to their release into the environment.
- India generates around 2 million tons annually but lacks official data and management.
E-waste or electronic waste refers to discarded electrical and electronic devices that have reached the end of their useful life. It contains toxic substances like lead, cadmium, and mercury that can pollute the environment and harm human health if not disposed of properly. Some of the metals in e-waste can be recovered and reused. Common examples include old computers, phones, TVs, and household appliances. The growing amounts of e-waste are challenging to manage due to the waste being complex, heavy, and toxic. Improper disposal of e-waste can lead to soil, water, and air pollution and negative health effects in humans. Key methods for managing e-waste include recycling to recover materials, landfilling, and inc

A Novel Method for Prevention of Bandwidth Distributed Denial of Service AttacksIJERD Editor
Distributed Denial of Service (DDoS) Attacks became a massive threat to the Internet. Traditional
Architecture of internet is vulnerable to the attacks like DDoS. Attacker primarily acquire his army of Zombies,
then that army will be instructed by the Attacker that when to start an attack and on whom the attack should be
done. In this paper, different techniques which are used to perform DDoS Attacks, Tools that were used to
perform Attacks and Countermeasures in order to detect the attackers and eliminate the Bandwidth Distributed
Denial of Service attacks (B-DDoS) are reviewed. DDoS Attacks were done by using various Flooding
techniques which are used in DDoS attack.
The main purpose of this paper is to design an architecture which can reduce the Bandwidth
Distributed Denial of service Attack and make the victim site or server available for the normal users by
eliminating the zombie machines. Our Primary focus of this paper is to dispute how normal machines are
turning into zombies (Bots), how attack is been initiated, DDoS attack procedure and how an organization can
save their server from being a DDoS victim. In order to present this we implemented a simulated environment
with Cisco switches, Routers, Firewall, some virtual machines and some Attack tools to display a real DDoS
attack. By using Time scheduling, Resource Limiting, System log, Access Control List and some Modular
policy Framework we stopped the attack and identified the Attacker (Bot) machines
Hearing loss is one of the most common human impairments. It is estimated that by year 2015 more
than 700 million people will suffer mild deafness. Most can be helped by hearing aid devices depending on the
severity of their hearing loss. This paper describes the implementation and characterization details of a dual
channel transmitter front end (TFE) for digital hearing aid (DHA) applications that use novel micro
electromechanical- systems (MEMS) audio transducers and ultra-low power-scalable analog-to-digital
converters (ADCs), which enable a very-low form factor, energy-efficient implementation for next-generation
DHA. The contribution of the design is the implementation of the dual channel MEMS microphones and powerscalable
ADC system.
Influence of tensile behaviour of slab on the structural Behaviour of shear c...IJERD Editor
-A composite beam is composed of a steel beam and a slab connected by means of shear connectors
like studs installed on the top flange of the steel beam to form a structure behaving monolithically. This study
analyzes the effects of the tensile behavior of the slab on the structural behavior of the shear connection like slip
stiffness and maximum shear force in composite beams subjected to hogging moment. The results show that the
shear studs located in the crack-concentration zones due to large hogging moments sustain significantly smaller
shear force and slip stiffness than the other zones. Moreover, the reduction of the slip stiffness in the shear
connection appears also to be closely related to the change in the tensile strain of rebar according to the increase
of the load. Further experimental and analytical studies shall be conducted considering variables such as the
reinforcement ratio and the arrangement of shear connectors to achieve efficient design of the shear connection
in composite beams subjected to hogging moment.
Gold prospecting using Remote Sensing ‘A case study of Sudan’IJERD Editor
Gold has been extracted from northeast Africa for more than 5000 years, and this may be the first
place where the metal was extracted. The Arabian-Nubian Shield (ANS) is an exposure of Precambrian
crystalline rocks on the flanks of the Red Sea. The crystalline rocks are mostly Neoproterozoic in age. ANS
includes the nations of Israel, Jordan. Egypt, Saudi Arabia, Sudan, Eritrea, Ethiopia, Yemen, and Somalia.
Arabian Nubian Shield Consists of juvenile continental crest that formed between 900 550 Ma, when intra
oceanic arc welded together along ophiolite decorated arc. Primary Au mineralization probably developed in
association with the growth of intra oceanic arc and evolution of back arc. Multiple episodes of deformation
have obscured the primary metallogenic setting, but at least some of the deposits preserve evidence that they
originate as sea floor massive sulphide deposits.
The Red Sea Hills Region is a vast span of rugged, harsh and inhospitable sector of the Earth with
inimical moon-like terrain, nevertheless since ancient times it is famed to be an abode of gold and was a major
source of wealth for the Pharaohs of ancient Egypt. The Pharaohs old workings have been periodically
rediscovered through time. Recent endeavours by the Geological Research Authority of Sudan led to the
discovery of a score of occurrences with gold and massive sulphide mineralizations. In the nineties of the
previous century the Geological Research Authority of Sudan (GRAS) in cooperation with BRGM utilized
satellite data of Landsat TM using spectral ratio technique to map possible mineralized zones in the Red Sea
Hills of Sudan. The outcome of the study mapped a gossan type gold mineralization. Band ratio technique was
applied to Arbaat area and a signature of alteration zone was detected. The alteration zones are commonly
associated with mineralization. The alteration zones are commonly associated with mineralization. A filed check
confirmed the existence of stock work of gold bearing quartz in the alteration zone. Another type of gold
mineralization that was discovered using remote sensing is the gold associated with metachert in the Atmur
Desert.
Reducing Corrosion Rate by Welding DesignIJERD Editor
This document summarizes a study on reducing corrosion rates in steel through welding design. The researchers tested different welding groove designs (X, V, 1/2X, 1/2V) and preheating temperatures (400°C, 500°C, 600°C) on ferritic malleable iron samples. Testing found that X and V groove designs with 500°C and 600°C preheating had corrosion rates of 0.5-0.69% weight loss after 14 days, compared to 0.57-0.76% for 400°C preheating. Higher preheating reduced residual stresses which decreased corrosion. Residual stresses were 1.7 MPa for optimal X groove and 600°C
Router 1X3 – RTL Design and VerificationIJERD Editor
Routing is the process of moving a packet of data from source to destination and enables messages
to pass from one computer to another and eventually reach the target machine. A router is a networking device
that forwards data packets between computer networks. It is connected to two or more data lines from different
networks (as opposed to a network switch, which connects data lines from one single network). This paper,
mainly emphasizes upon the study of router device, it‟s top level architecture, and how various sub-modules of
router i.e. Register, FIFO, FSM and Synchronizer are synthesized, and simulated and finally connected to its top
module.
Active Power Exchange in Distributed Power-Flow Controller (DPFC) At Third Ha...IJERD Editor
This paper presents a component within the flexible ac-transmission system (FACTS) family, called
distributed power-flow controller (DPFC). The DPFC is derived from the unified power-flow controller (UPFC)
with an eliminated common dc link. The DPFC has the same control capabilities as the UPFC, which comprise
the adjustment of the line impedance, the transmission angle, and the bus voltage. The active power exchange
between the shunt and series converters, which is through the common dc link in the UPFC, is now through the
transmission lines at the third-harmonic frequency. DPFC multiple small-size single-phase converters which
reduces the cost of equipment, no voltage isolation between phases, increases redundancy and there by
reliability increases. The principle and analysis of the DPFC are presented in this paper and the corresponding
simulation results that are carried out on a scaled prototype are also shown.
Mitigation of Voltage Sag/Swell with Fuzzy Control Reduced Rating DVRIJERD Editor
Power quality has been an issue that is becoming increasingly pivotal in industrial electricity
consumers point of view in recent times. Modern industries employ Sensitive power electronic equipments,
control devices and non-linear loads as part of automated processes to increase energy efficiency and
productivity. Voltage disturbances are the most common power quality problem due to this the use of a large
numbers of sophisticated and sensitive electronic equipment in industrial systems is increased. This paper
discusses the design and simulation of dynamic voltage restorer for improvement of power quality and
reduce the harmonics distortion of sensitive loads. Power quality problem is occurring at non-standard
voltage, current and frequency. Electronic devices are very sensitive loads. In power system voltage sag,
swell, flicker and harmonics are some of the problem to the sensitive load. The compensation capability
of a DVR depends primarily on the maximum voltage injection ability and the amount of stored
energy available within the restorer. This device is connected in series with the distribution feeder at
medium voltage. A fuzzy logic control is used to produce the gate pulses for control circuit of DVR and the
circuit is simulated by using MATLAB/SIMULINK software.
Study on the Fused Deposition Modelling In Additive ManufacturingIJERD Editor
Additive manufacturing process, also popularly known as 3-D printing, is a process where a product
is created in a succession of layers. It is based on a novel materials incremental manufacturing philosophy.
Unlike conventional manufacturing processes where material is removed from a given work price to derive the
final shape of a product, 3-D printing develops the product from scratch thus obviating the necessity to cut away
materials. This prevents wastage of raw materials. Commonly used raw materials for the process are ABS
plastic, PLA and nylon. Recently the use of gold, bronze and wood has also been implemented. The complexity
factor of this process is 0% as in any object of any shape and size can be manufactured.

Secure Image Transmission for Cloud Storage System Using Hybrid SchemeIJERD Editor
- Data over the cloud is transferred or transmitted between servers and users. Privacy of that
data is very important as it belongs to personal information. If data get hacked by the hacker, can be
used to defame a person’s social data. Sometimes delay are held during data transmission. i.e. Mobile
communication, bandwidth is low. Hence compression algorithms are proposed for fast and efficient
transmission, encryption is used for security purposes and blurring is used by providing additional
layers of security. These algorithms are hybridized for having a robust and efficient security and
transmission over cloud storage system.
Application of Buckley-Leverett Equation in Modeling the Radius of Invasion i...IJERD Editor
A thorough review of existing literature indicates that the Buckley-Leverett equation only analyzes
waterflood practices directly without any adjustments on real reservoir scenarios. By doing so, quite a number
of errors are introduced into these analyses. Also, for most waterflood scenarios, a radial investigation is more
appropriate than a simplified linear system. This study investigates the adoption of the Buckley-Leverett
equation to estimate the radius invasion of the displacing fluid during waterflooding. The model is also adopted
for a Microbial flood and a comparative analysis is conducted for both waterflooding and microbial flooding.
Results shown from the analysis doesn’t only records a success in determining the radial distance of the leading
edge of water during the flooding process, but also gives a clearer understanding of the applicability of
microbes to enhance oil production through in-situ production of bio-products like bio surfactans, biogenic
gases, bio acids etc.
Gesture Gaming on the World Wide Web Using an Ordinary Web CameraIJERD Editor
- Gesture gaming is a method by which users having a laptop/pc/x-box play games using natural or
bodily gestures. This paper presents a way of playing free flash games on the internet using an ordinary webcam
with the help of open source technologies. Emphasis in human activity recognition is given on the pose
estimation and the consistency in the pose of the player. These are estimated with the help of an ordinary web
camera having different resolutions from VGA to 20mps. Our work involved giving a 10 second documentary to
the user on how to play a particular game using gestures and what are the various kinds of gestures that can be
performed in front of the system. The initial inputs of the RGB values for the gesture component is obtained by
instructing the user to place his component in a red box in about 10 seconds after the short documentary before
the game is finished. Later the system opens the concerned game on the internet on popular flash game sites like
miniclip, games arcade, GameStop etc and loads the game clicking at various places and brings the state to a
place where the user is to perform only gestures to start playing the game. At any point of time the user can call
off the game by hitting the esc key and the program will release all of the controls and return to the desktop. It
was noted that the results obtained using an ordinary webcam matched that of the Kinect and the users could
relive the gaming experience of the free flash games on the net. Therefore effective in game advertising could
also be achieved thus resulting in a disruptive growth to the advertising firms.

LCC resonant converter it is associated with a disadvantage that, though it has two resonant frequencies, the
lower resonant frequency is in ZCS region[5]. For this application, we are not able to design the converter
working at this resonant frequency. LLC resonant converter existed for a very long time but because of
unknown characteristic of this converter it was used as a series resonant converter with basically a passive

resonant converter is narrow switching frequency range with light load[6] . Basically, the control ckt plays a
very imp. role and hence 555 Timer used here provides a perfect square wave as the control ckt provides no
slew rate which makes the square wave really strong and impenetrable. The dead band circuit provides the
exclusive dead band in micro seconds so as to avoid the simultaneous firing of two pairs of IGBT’s where one
pair switches off and the other on for a slightest period of time. Hence, the isolator ckt here is associated with
each and every ckt used because it acts as a driver and an isolation to each of the IGBT is provided with one
exclusive transformer supply[3]. The IGBT’s are fired using the appropriate signal using the previous boards
and hence at last a high frequency rectifier ckt with a filtering capacitor is used to get an exact dc

“MS-Extractor: An Innovative Approach to Extract Microsatellites on „Y‟ Chrom...IJERD Editor
Simple Sequence Repeats (SSR), also known as Microsatellites, have been extensively used as
molecular markers due to their abundance and high degree of polymorphism. The nucleotide sequences of
polymorphic forms of the same gene should be 99.9% identical. So, Microsatellites extraction from the Gene is
crucial. However, Microsatellites repeat count is compared, if they differ largely, he has some disorder. The Y
chromosome likely contains 50 to 60 genes that provide instructions for making proteins. Because only males
have the Y chromosome, the genes on this chromosome tend to be involved in male sex determination and
development. Several Microsatellite Extractors exist and they fail to extract microsatellites on large data sets of
giga bytes and tera bytes in size. The proposed tool “MS-Extractor: An Innovative Approach to extract
Microsatellites on „Y‟ Chromosome” can extract both Perfect as well as Imperfect Microsatellites from large
data sets of human genome „Y‟. The proposed system uses string matching with sliding window approach to
locate Microsatellites and extracts them.
Importance of Measurements in Smart GridIJERD Editor
- The need to get reliable supply, independence from fossil fuels, and capability to provide clean
energy at a fixed and lower cost, the existing power grid structure is transforming into Smart Grid. The
development of a smart energy distribution grid is a current goal of many nations. A Smart Grid should have
new capabilities such as self-healing, high reliability, energy management, and real-time pricing. This new era
of smart future grid will lead to major changes in existing technologies at generation, transmission and
distribution levels. The incorporation of renewable energy resources and distribution generators in the existing
grid will increase the complexity, optimization problems and instability of the system. This will lead to a
paradigm shift in the instrumentation and control requirements for Smart Grids for high quality, stable and
reliable electricity supply of power. The monitoring of the grid system state and stability relies on the
availability of reliable measurement of data. In this paper the measurement areas that highlight new
measurement challenges, development of the Smart Meters and the critical parameters of electric energy to be
monitored for improving the reliability of power systems has been discussed.
Study of Macro level Properties of SCC using GGBS and Lime stone powderIJERD Editor
The document summarizes a study on the use of ground granulated blast furnace slag (GGBS) and limestone powder to replace cement in self-compacting concrete (SCC). Tests were conducted on SCC mixes with 0-50% replacement of cement with GGBS and 0-20% replacement with limestone powder. The results showed that replacing 30% of cement with GGBS and 15% with limestone powder produced SCC with the highest compressive strength of 46MPa, meeting fresh property requirements. The study concluded that this ternary blend of cement, GGBS and limestone powder can improve SCC properties while reducing costs.

Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.

Abstract:- The mammoth growth of waste in general and electronic waste in particular is a growing threat to
the health and environmental issues the world is facing today. The electronic waste ( e waste) constitutes
around 2.7 to 3 % of the total waste and in majority contains hazardous and toxic elements which have many
elements and constituents which when handled carelessly i.e. without proper care and protection will lead to
numerous health and environmental problems which can be deadly and endangering the life of living beings.
The proper advocacy and information passage to the consumers is day by day becoming utmost urgent
requirement. The hazardous effects of the constituents ranges from irritation to development of deadly cancer
and is endangering the existence itself. Proper regulation development means and facilities of recycling and
disposal are need of hour and time. The threats are numerous and are indicator of concerns is growing
requirement. The regulations so far enacted are inadequate and lack from total commitment to deal with the
situation. The latest regulations are steps towards betterment but are still far from satisfactory. The global
situation of passing the buck is also threat for the developing and underdeveloped countries as the disposal in
informal sector is predominant in these areas. The means are minimal and the value of life is valueless and the
appropriateness of health facilities is also far from satisfactory. The dependence on developed nations further
adds to the problems.
Keywords:- E waste, Hazardous, Leaching, Toxic, Health, Immune System, Environment, EEE
I. INTRODUCTION
The modernization and latest mindset in general, consumer behavior in particular and tendency of
making life automated and mechanized requires the development of Electrical & Electronic Equipments (EEE).
These EEE and electronic gadgets are the basic modes and ideas getting generated. The rapidly changing and
technological development are pushing the existing EEE to the new profile consumers making place for the
affluent consumers opting for the newer products. The transfer of EEE to sectorial and classical classes of
consumerisation gives rise to secondary markets and new dimension of market growth. The shifting of EEE
sometimes leads to defects in the products which may not find replacement or be repaired and lead to end of life
of the product requiring disposal. The excessive use and obsolesce also leads to end of life of products. The end
of life and situation where the products are left with option of non utilization and non application or have
become hazardous leads to growth of waste popularly known as Electronic Waste (e waste) or WEEE. The
dimension of industrial pollutants released into environment mixed with the new e waste adds to the problem.
The e waste mainly consists of high use and consumer driven day to day usable and being used like mobile,
smart electronic gadgets, television, computers, laptops, printers, photocopy machines, toys, house hold electric
appliances etc. These are mostly made-up of plastics, metals, and other materials which are sometimes
hazardous also. The toxic contents of the e waste makes it more vurnable and hazardous. The constituent are
roughly in proportion of 60 % which comprises iron, copper, aluminum, gold and other metals The presence of
plastics account roughly to t 30% and the being talked hazardous pollutants responsible for health hazards are
around 2.70% to 3 %. Electronic equipments results in a mix of materials and components containing several
hundreds of substances which can be toxic and may be responsible for serious pollution when these are
disposed off after becoming e waste. The materials responsible for such pollution ranges from heavy metals like
mercury, lead, cadmium, chromium to flame retardants such as polybrominated biphenyls (PBB) and
polybrominated diphenyethers (PBDEs).
The workers involved in industries manufacturing electronics chips, drives and circuit boards are
reporting serious health problems. Employees and labors engaged in recycling, extracting valuables from e
wastes and handling e-waste as scrap are observed to have health problems caused by toxic hazardous pollutions
caused by various types of pollutants. The careless disposal of e wastes is posing threats by showing signs of
deterioration of local drinking water. The ill effects and possible hazards of e-waste have to be recognized.

1. Different Categories and constituents of E-waste
E-waste means electrical waste and electronic equipment, whole or in part included in, but not confined
to equipment, scraps or rejects from their manufacturing process. E-waste is divided into different categories
according to Environment Protection Act, 1986 (figure 1). Figure 2 shows composition of e wastes in terms of
percentage.
Figure 1 Composition /categories of e waste
Figure 2 Composition of e waste
Hazardous Components of E-Waste: The main composition or constituents responsible for health and
environment concern are Americium , Arsinic , Barium , Beryllium , Lithium, Nickel, Mercury, Sulphpur ,
Lead , Cadmium, Chromium, Beryllium Oxide, Brominated flame retardants (BFR), Rare earth elements etc.
The brief descriptions of presence and basic threats are as follows:-
Americium is basically radioactive sources present in the e waste. It is also known as carcinogenic.
Arsenic : These are present in form of GaAs in form of LEDs. After disposal when mixes in the soil can lead to
very harmful affect to health.
Barium: These are present in form of getters in the CRT. These when come in contact of moisture can lead to
explosive gases which can cause burns and other toxic affects.
Beryllium : Present in the power supply which contains SCR and beam line components. These are harmful if
inhaled.
Lithium : Often these are in the lithium batteries. Can cause burns when comes in contact with moisture or
becomes wet.
Nickel : Often present in the NiCd batteries used in electronic equipments for power sources. These are
extremely poisonous and harmful in long run.
Mercury: The perfect liquid conductor often finds place in the fluorescent tubes, tilt switches, conducting
electronic tubes, control solid state devices and flat screen monitors. The harmful effect on contacting include

dermatitis, sensory impairment, memory loss, weakness in muscle reduced fertility causing slowing of growth
and development etc. The severe effect can be resulting in death of living beings when affected.
Sulphur: The main source can be witnessed in lead-acid batteries. Hazardous effects on contact and inhalation
include heart damage, liver damage, kidney damage, and eye and throat infections causing irritation. In
environment it can be source of formation of Sulphuric Acid in humid and wet conditions which can lead to loss
of fertility of land etc.
Lead: Lead-acid batteries are the main source. It is present in the CRT monitor glass etc. The amount of lead in
the CRT tube can vary from 1.5 pounds to 8 pounds.
Cadmium: In electronic products main sources are cadmium batteries, light-sensitive resistors, florescent layer
of the CRT and printer inks and toners. If these are allowed in day to day use and particularly in corrosion
alloys for marine and aviation environments they can cause severe health problems. The presence of cadmium if
allowed in the soils then it can leach into the soil and harm the microorganism and disrupt the ecosystem of soil.
If person comes in contact by inhalation in the sites of recycling without proper care it can cause severe damage
to lungs and kidney.
Beryllium oxide: These are Fillers mostly for the thermal interface materials and are mostly used as heat
transfer fins in vacuum tubes lasers, CPUs and power transistors, magnetrons, X ceramic windows etc .
Brominated flame retardants (BFR): The BFR are mostly used as flame retardants in plastics for the
electronics product and these includes the banned product PBBs, PCB , Octa BDE, Penta BDE. The hazardous
hygienic and health effects ranges from thyroid problem , impaired development of the nervous system etc.
Rare earth elements are often present in the florescent layers of CRT and these can cause irritation to eyes
skins.
II. E WASTE SCENARIO IN INDIA
The Manufactures Association of Information Technologies (MAIT) in its report of 2007 has
generated 380000 tonnes of e waste mostly comprising of disposed Computers , TV and Mobile Phones. The
projection as been predicted to touch 800000 tonnes by 2012. The average increase in e waste growth is around
15 % The global growth rate is 50 million tonnes per annum. The china and US waste growth annually are 2.3
million tonnes and 3 million tones while of India it is 400000 tones per annum .
The key e waste generators sector wise are basically categorized as Individual households, Govt.,
Public and private sector (over 70%), Retailers, manufacturers, Secondary market and Imports.

III. FORMAL RECYCLERS AND DISPOSAL UNITS IN INDIA
The present condition of formal and informal recycling and disposal activities in India is alarming.
Only 5 % e wastes recycling and disposal is done in the formal sector leaving remaining 95 % to be handled by
the informal sector. The present scenario is that the recycling and disposal activities in the formal sector being
undertaken at the following centres:-
E-Parisaraa Pvt Ltd. (first government-authorized eco-friendly recycling unit )
Earth Sense Recycle Private Limited (Joint venture of E-Parisaraa Private Limited and M/S. GJ Multiclave
India Private Limited)
Trishyiraya Recycling India Pvt. Ltd (TPL) (The GOI & Pollution Control Board certified company for
disposal of e waste)
Plug-in to e Cycling (Environmental Protection Agency and consumer electronics manufacturers, retailers, and
service providers joint venture)
The Manufacturers’ Association for Information Technology (MAIT) initiated Electronics Recyclers’
Association (ERA)
Besides these there are other not noticeable agencies to be listed out here.
IV. IMPACTS OF E WASTES
The changing structure of procurement of EEE and its transfers to the various layers and sections often
lead to the non use and disposal in an unattended way by the section who is not affordable and does not have
knowledge of ill effects of these discarded e wastes. The society of various economic sections exists throughout
world and it has lead to a global phenomenon. The hazardous and toxic contents in the e wastes affect the
environment and human health. Unknowingly the e-waste takes up space in the communities and sections it
penetrates through in name of modernization and advancement and can result to be very harmful to humans and
other living beings. The toxicity and carcinogenicity of some of the substances present in the e waste if disposed
improperly processed can lead to severe harmful effects. E-waste contains mostly electronic gadgets which
contain thousands of components having deadly chemicals and metals like lead, cadmium, chromium, mercury,
polyvinyl chlorides (PVC), brominated flame retardants, beryllium, antimony and phthalates are the main source
of concern than the other waste materials. The exposure to the substances which can be carcinogenic and neuro-
toxic in nature present in the e waste can cause damages to the nervous systems, kidney and bones, and the
reproductive and endocrine systems besides affecting the environment. Primitive and unscientific recycling or
crude disposal of e-waste to landfills like other wastes may lead to irreversible environmental damage by
polluting water and soil, and contaminating air which we inhale for breathing.
Various studies by formal and informal sectors in major cities including the national capital Delhi by
formal and informal sectors reveals that in 2005 in case of electronic recycling yards in Delhi confirmed the
presence of high levels of hazardous deadly Dixons and furans chemicals in the areas where present. Workers
are poorly protected against the risk of hazardous ingredients in e-waste disposal sites. Normally the workers
(workforce of 25000) perform the dismantling of e wastes of the tune of 10000 to 20000 tons by hand without
any protection .The e wastes being handled are about 25 % reaching in this region. Mumbai, Chennai,
Bangalore, Kolkata, Meerut, Firozabad, Poona and many other localities the e waste scrap yards exist. The
presence of hazardous substances like lead, cadmium, chromium and flame-retardant plastics are present in
subsequent quantity. High lead content CRT and components content are considered most dangerous to health.
5. Electronic Waste: Emerging Health Threats
21
Handling by naked hands i.e. without protection and inhaling such hazardous toxic and dangerous substances
can damage the nervous system, lungs, kidneys and the reproductive system and even brain. Often such
dismantling works are carried out in confined areas without proper ventilation without masks and required
technical expertise results in attacks of dangerous and slow-poisoning chemicals by exposer. Lack of awareness
is further reason of risk to the health and environment. The environmentalist and scientists who have examined
the areas having e waste recycling and disposal activities have found that the dioxins causing cancer exist in
those areas. The women workers who are pregnant are at additive risk to the extent that they are six times more
susuptable than their counterparts. The women workers are at greater risk of even miscarriage. The kids who
work because of extreme poverty to meet the two ends of meals in the family it is observed that seven out of ten
kids have high lead content in their blood. At present there is no reliable data available for these studies
particularly in case of child labors and fairer sex.
In order to extract the metals from e wastes chemical leaching is done. The chemical leaching can be
done by either by using acid or ligand supported complication or by involving complexometry. In later case the
ligands get complexed with metals. In chemical leaching the H2SO4 or HCl or H2SO4 with HNO3 acids are
used for extraction of metals from the E-waste. The extraction can be done using Sodium hypochlorite with
acid or alkali for the recovery of gold and other precious metals The use of organic solvents are done for
extraction of heavy metals like Fe, Cu, Al, Ni, Au and Ag. Use of sulfuric acid and hydrogen-peroxide is
normally done for extraction of copper from discarded Printed Circuit Boards (PCB).
The use of acidophilic group of bacteria plays an important role in extraction of heavy metals from the
wastes in biological leaching. Particularly in case of Acidithiobacillus ferrooxidans, Acidithiobacillus
thiooxidans, Lep-tospirillum ferrooxidans, and Sulfolobus the bioleaching is economical. It s observed that in
the earth’s crest for inorganic and organic matters the microorganisms are active in the formation and
decomposition. Here the natural ability of microbes namely Autotrophic , heterotrophic bacteria and
heterotrophic fungi are used to transform solid metallic compounds to its solubility and extractable form are
employed in the bioleaching This is effective in case of metals Chemolithotrophs of iron-and sulfur-oxidizing
nature. The chemical and biological leaching has their own risks as handling of acids are highly dangerous
where as microorgans have their own risks to persons involved in extraction from the e waste.
The major constituent of the e waste which is day by day becoming need of growth and development is
the PC. On an average each PC contains the following constituents 7.24 kg plastics, 1.98 kg of lead, 9.92g of
barium, 4.94g of beryllium, 2.961g of cadmium, 1.98g of chromium, 0.693g of mercury, 0.4095g of arsenic etc.
V. E WASTE HAZARDOUS TOXIC AFFECTS
The e waste contains numerous hazardous and toxic constituents responsible for many health and
environment degradation specially while recycling or disposing in unsafe and crude manner. The major
components of e wastes, its constituents and health effects of part of body effecting can be summarized as

VI. CONCLUSION
The current situation of waste in general and e waste in particular and the addressing of the
composition and constituents of the hazardous and toxic population of the e waste is of main concern. The
Recycling and disposal requirements are specialized ones but the facilities available when compared to
production and use through various means have a large gap . The poverty and illiteracy are the major factors
which do not get persons get the proper knowhow for protection from the hazardous ingredients which one
comes across while working in recycling and disposal institutions and industries. The pushing of old and
obsolete appliances and equipments in name of technology transfer is becoming affair of the developed nations.
This is means of saving themselves from the means of disposal and thereby pushing away the threats of
radioactive radiations and environmental exposer to have-not regions. Due to this tendency the human kind is at
stake. The various constituents and compositions of e waste cause the damage which ranges from irritation to
deadly effects to the extent of development of cancer. Proper regulation development and means and facilities of
recycling and disposal is need of hour and time. The treats are numerous and concerns are also required. The
regulations so far are inadequate and lack from total commitment to deal with the situation. The latest
regulations are steps towards betterment but are still far from satisfactory. The global situation of passing the
buck is also threat for the developing and underdeveloped countries as the disposal in informal sector is

predominant in these areas. The means are minimal and the value of life is valueless and the appropriateness of
health facilities is also far from satisfactory. The dependence on developed nations further adds to the problems.
