E waste management ppt

E-waste refers to discarded electronic devices, which can include anything from computers and televisions to kitchen appliances. Managing e-waste is crucial to mitigate environmental pollution and health risks from harmful substances released during disposal, with only 12.5% of e-waste globally being recycled. Different countries have adopted various strategies for e-waste management, with Japan leading in recycling initiatives, while the U.S. primarily exports e-waste for cheaper, less regulated processing.

WHAT IS E-WASTE..? Electronic waste describes discarded electrical or electronic devices . Used electronics which are destinated for refurbishment .recycling through material recovery or disposal are also considered as e-waste.
EXAMPLES OF E-WASTE..  E-waste is obtained fromTV’s, computers, mobiles ,circuits chips,DVD,CD’S,MP3 players etc…  And also in kitchen equipment like toasters,coffee makers, microwave ovens etc…,  Broken computer monitors ,Television tubes mostly in CRT(cathode ray tubes).  Any laboratory equipment that has the possibility of being contaminated with chemical biological or radio active substances must be cleared through EH&S development facilities office before disposal..
WHY E-WASTE MANAGEMENT IS IMPORTANT..  Here are some reasons why e-waste management is so important .  THERE’S MORE E-WASTETHEN EVER:  According to the university of Columbia earth institute block 49 billion tons of e-waste in 2016,and that number is on track to grow to 60 billion tons by 2021.  By managing our e-waste properly ,we can reduce the amount of hazardous electronics waste we send to land fills.Therefore, we can reduce the amount of pollution that we release into the environment.
 Unfortunately ,many electronic devices go straight into the garbage after we’re done using them.Infact according to the EPA, only 12.5% of global e-waste is recycled.  Recycling and disposal of e-waste may involve significant risk to health of workers an communities in developed countries ,Great care should be taken.
 Generally for the preparation of an electronic device we use different valuable, hard parts. After the usage of that device we throw it.  To avoid this situation parts like iron-based metal, glass & plastic castings can be melted down and reused as raw materials.
 If the time period of a device is ended ,we transfer the information from old devices to the new devices ,in this process the sensitive data still exists in the device.  On means of above problem “YAHOO & EQUIFAX’S” major security has collapsed.The company liabilities has been exposed  So ,Be sure double-check for security liabilities before you handle your e-waste.
 DONATIONS:  By donating the e-waste we can transform the inconvenience into a valuable asset once more..  We can donate the following: computers monitors Televisions Cell phones Ipads Cables(USB,AUXetc..) Large companies like electronic distributers and manufactures will accept donations. You can donate if the data on your equipment has been entirely sanitized. This donations increase product lifespan and prevent further environmental pollution.
EFFECT OF THE E-WASTE ON ENVIRONMENT..  When e-waste is dumped in land fills it seeps into groundwater reservoirs and eventually out into rivers ,lakes , oceans effecting marine habitants.  Once the toxic from e-waste enters the eco- system it is very difficult to remove it.
EFFECTS ON HUMANHEALTH..  In e-waste management generally in the process of melting ,dismantling etc..the toxic materials like lead ,cadmium, mercury etc releases into atmosphere.  LEAD: lead can be spread through inhalation, skin contact, which causes nausea, coma, even death.  CADMIUM: it can found in rechargeable batteries ,it is mostly used.when cadmium release while dismantling, it accumulates in the near by crops and in the humans and animals. it results in kidney failures, bone problems, hyper tension, learning capacity in children..
GUIYU is a place in china where the 65% of worlds e-waste is treated ,due to this the women in guiyu miscarriage rate was increased and children have high lead levels in their blood streams. And also suffering from mental disorders. MERCURY: it is most popular metals used in electronic devices. it mainly effects on the central nervous system ,on spreading of this causes tremours,fever,vomitings.. It is used in house hold products like batteries,fluroscent lamps,thermostarters etc…
E-WASTE MANAGEMENT IN DIFFERENT COUNTRIES..  China(7.2 million tons per annum)  USA(6.3 million tons per annum)  Japan(2.1 million tons per annum)  INDIA(2.0 million tons per annum)  Germany(1.9 million tons per annum)
IN JAPAN:  Japan is first country to implement electronic waste recycling program.  They had implemented many laws in favour with e-waste management.  One of he law : Japan citizens if they buy any appliances likeTV’S ,AC etc..when they send for recycling process they will get some money back as 50% ofTV and 70% of AC.
 Japan is also planning to use the e-waste in olympics.in gold metals at least 6grms of gold should be present remaining composition is with e-waste, by which it becomes more strong and durable. Japan Olympic organize committee launches it by 2020.
IN USA:  US should second position in producing e-waste.  They generally manage the e-waste by exporting it to the place where the environmental restrictions are less, and where the people has less technical knowledge about e- waste ,transports to that destination.  And they burn the e-waste in rural areas ,because it is the cheapest option. By burning they extracts the metals like gold etc..  They will test the e-waste if there is any chance of function, remaining turns into ashes.
IN CHINA:  China has took the first rank in increasing the volume of e-waste.  Actually in china e-waste disposal sector is responsible for many jobs in rural areas certainly in southeastern part of china.  China was the largest importer of the e-waste due to the cheap labour and environmental standards. But later govt. of china banned this process. but in some places illegally it is active..
 E-waste management in china continue rises with china’s economic development, technical innovation, and urbanization as more electronics are created and consumed and disposed.  China manages the e-waste in maximum possible ways i.e.., manual dismantling and chemical seperation,through which maximum e- waste is recycled ,re-used, and reformed.  70% worlds e-waste is treated and it employees around 100,000 people.
IN INDIA:  E-waste is recycled 75% in india.it is transformed into suitable materials.  We also set up the micro factories in India that can transform e-waste into reusable materials to be converted into ceramics and plastic filaments for 3D printings etc..  We extract useful metals from e-waste which is processed in temperature controlled areas, instead of open burning they extract like gold, silver, copper etc..and also plastic.  And also providing the jobs on e-waste management…
OUR ROLE IN E-WASTE MANAGEMENT:  The only role of us is to aware the people about the effects of e-waste, and its management.
