  3. 3. E-Waste is a term used to cover items of all types of electrical and electronic equipment (EEE) and it’s parts that have been discarded by the owner as waste without the intention of re-use. 3 https://equalconsultancy.com/new/e-waste-registration/
  4. 4. According to nation university global e-waste monitoring 2020, in 2019 Total global e-waste generated 53.6 million tonnes in world wide, and estimated to be increased 38% in 2030. In Delhi per year Two lakh(200,00) tonnes e-waste are generated. 4 https://curlytales.com/india-first-e-waste-eco-park-to-come-up-in-delhi/

  7. 7. 7 E-WASTE AFFECT THE ENVIRONMENT Improper disposal of these electronic wastes affects the environment which shows on : • Air • Soil • Water Air :- • Electronic waste can contribute to air pollution. • Toxic chemicals are released into the air and damaging the atmosphere. https://www.google.com/imgre https://greenland-recycling.com/e-waste-recycling-in-uae
  8. 8. 8 Soil :- • Heavy metals in the e-waste can directly from e-waste into the soil. • Harmful to microorganisms and plant metabolism. • Damage cell structure and reduced growth rate of microorganism. • Causes the contamination of underlying groundwater. Water :- • Acidification of surface waterways. • Kill marine and freshwater organisms. • Disrupt biodiversity and aquatic ecosystems. https://www.istockphoto.com/search/2/image https://www.indiamart.com/proddetail/e-waste-electronic- recycling-waste-18192575473.html
  9. 9. 9 Metal Sources Health effect Lead Glass panels , gaskets of computer monitors ,and circuit boards. Lead causes damage to the central nervous system , blood system , kidney and reproductive system. Cadmium Infrared detectors and semiconductor chips. Toxic cadmium compounds accumulate in human body, specially the kidneys. Mercury Mercury is used in thermostats, sensors, lamp, mobile phones and in batteries. Mercury can cause damage to organs including the brain and kidneys. Chromium Chromium is used as corrosion protector and use in cabling. Chromium can cause damage to DNA and extremely toxic in the environment. Barium Barium is a soft silvery white metal that is used in in the front panel to protect users from radiation. Barium causes brain swelling, muscle weakness, damage to the heart , liver . Beryllium Beryllium is commonly found on motherboards and finger clips. Exposure to beryllium can cause lung cancer, skin disease. Arsenic Cathode ray tube etc. Arsenic can causes lung and skin cancers may cause other cancer. SOURCES AND ITS HEALTH EFFECT

  11. 11. WHAT DO WE DO WITH THIS E-WASTE ? Step 1. • Once the waste arrive at the Eco-park, • An operator shows the individual where each item should be deposited. Step 2. • When the containers are full, they are transferred to plants where the usable materials are recycled and converted into new raw materials. Step 3. • Products that are particularly hazardous are treated prior to recovery or disposal in order to avoid environmental and health problems. 11
  12. 12. Delhi to get nations first E-waste eco-park E-waste eco-park where Dismantling, Re-cycling, Disposal and Re-manufacturing of the E-waste will be done in a safe and scientific manner. On February 24, 2022, the Deputy Chief Minister of Delhi, Mr. Manish Sisodia, announced that Delhi will get India’s first e-waste eco-park. http://currenthunt.com/2022/03/countrys-first-e-waste- management-eco-park-to-be-built-in-delhi 12

  15. 15. PRACTICAL ISSUE WITH E-WASTE ECO-PARK 1. Physical characteristics:-  E-waste-Mixed with biodegradable waste.  Presence of hazardous waste. 2. Lack of awareness. 3. Unplanned growth & development of cities. 4. This results in many life-threatening incidents like fires breakout. 5. It also impacts the health of waste handlers. 15
  16. 16. WHY IS E-WASTE AWARENESS IMPORTANT ? • These discarded products affect the environment negatively. • Apart from affecting the environment, it can also affect the health of the people; Hence, managing this E-waste effectively is important and its awareness is also important. 16
  17. 17. ADVANTAGES OF ECO-PARK • Effective management of e-waste. • Create jobs and boost the economy. • It will have facilities for extraction of precious metals like gold, silver, copper among others, especially from Printed Circuit Boards (PCBs) through high-end technologies. • There will be end-to-end processing of e-waste with zero landfill. • Recycled material can be used on developing new equipment. 17
  18. 18. CONCLUSIONS 18 E-waste can contain hazardous substances and its improper treatment leads to adverse effects for human health and the environment. Our eco-park will reduce pollution across the capital. In India ninety-five percentage of the e-waste is being recycled in non-formal sector and only five percentage e-waste recycle in formal unit. https://www.google.com/search?q=kbadi+wala+image&oq=kbadi+wala +image&aqs=chrome..69i57j0i10l2j0i10i457j0i402j46i10i175i199j0i10l 4.8872j0j15&sourceid=chrome&ie=UTF-8
