1. a) The fastest growing segment of waste
  2. b) Most valuable due to its basic composition
  3. c) Very hazardous if not handled carefully.

 However, the sector is very new with only a few corporate players in India and globally.  Most of the electronic waste management sector is currently handled by the unorganized / informal sector in India. However due to lack of skills, knowledge, awareness, etc., the sector has remained highly labour intensive, environmentally unfriendly and unhealthy. If done in the right way, and in an organized fashion, e-waste management can become a dominant economic sector.

 The purpose of this document is to present a project report on electronic waste recycling as a financially rewarding business. We find that the e-waste business is highly profitable from the economic as well as environmental perspective. There are some established success stories around the world as well as a few in India. However, it is perceived that the unorganized sector has a cost advantage. Hence the organized waste management remains limited. We, at Response, hold the opinion that the costs of the unorganized sector are not necessarily lower than the organized sector especially when we consider three major aspects:

  1. a) Rising cost of labour b) Limited efficiency of labour c) Low quality of the final output

Automated or semi-automated large capacity plants require less labour can consistently work at high efficiency and produce a much better quality of the final product. Therefore, they are extremely cost effective in the long run. Thus, even if there is competition of the unorganized sector, e-waste management can be an economically viable and a high returns business for the organized industry.   

 Fundamental Understanding of e-Waste and Handling Practices

What is e-Waste?

Old electronic equipment that have outlived their useful life are categorized as e-waste.

On an average, in India, in case of mobile phones the useful life goes upto 2 years. In case of PCs, it may go upto 5 years. The life of these equipment is extended due to reasons such as upgrade, repair and reuse, donation to charity, etc.

 E-Waste Categories and Classification

E-Waste is categorized by the government of India under the broad class of hazardous waste. Within e-Waste, there are several categories such as Large and small household appliances, electrical and electronic toys and sporting equipment, tools, computers and related equipment etc. A detail categorization as adopted by the Central Pollution Control Board of India is given in Appendix I.

 

Composition of e-waste

Electrical and Electronic equipment contains metallic and non metallic elements, alloys and compounds such as Copper, Aluminum, Gold, Silver, Palladium, Platinum, Nickel, Tin, Lead, Iron, Sulphur, Phosphorous, Arsenic etc. If discarded in the open, these metals can cause a severe environmental and health hazard.

It is difficult to identify the level of content of each metal. For each category of electronic equipment, each manufacturer, each model may have different composition. However based on various studies and experiments, we can establish average benchmarks for some products.

In reality, all metals cannot be recovered due to technology limitations and commercial viability. In real world, the major metals recovered are Gold, Platinum, Palladium, Nickel, Copper, Silver, Zinc, Iron, and Aluminum. Major non metals recovered are Lead, Phosphorous. Other items are plastic and glass. It may make economic sense to focus on only a few items and dispose the remaining.

 

Informal  recycler. These metals are sold to smelters. In most cases, the extraction techniques are so crude that the output is also contaminated. Also the efficiency of such techniques is only about 30%.

From the usable part of the collected WEEE, some is sold directly in second hand sale, some is refurbished and sold as a refurbished product, some is donated to charity and some is rented.

Overview of the Process and Plant layout

 The process steps are as under:

  1. Collection
  2. Aggregation
  3. Classification
  4. Processing of different types of classes : Batteries, CRT tvs, monitors, etc are not to be recycled or dismantled in this premises. Such types of WEEE will be offloaded to other registered recyclers who have the facility of handling the same.
  5. Dismantling
  6. Classification of dismantled parts
  7. The process inside the plant includes size reduction, granulation, ferrous metal separation, non ferrous mixed metal separation and non metals separation.

 The separation process does not generate any effluents. It is a completely mechanical process.

The entire process is a mix of manual and automated tasks so that the activity remains economically viable. Manual tasks are all hazard free and all standard safety precautions are taken. Automated tasks are conducted in sealed chambers wherever required for safety purposes. For such a facility approximately 15000 sq ft of land is provisioned.
