Recycling - Waste Picking

Waste-pickers can be seen at work in the landfills of almost all cities in India. They earn around Rs. 100 – 200 per day ($ 2 – 4) in cities like Mumbai and Delhi; their earnings are much lesser in other parts of the country. Waste-pickers work on tons of heaps of solid waste dumped by trucks every day before the heaps are aligned. The depth of these heaps before aligning (not compaction) can be assumed to be a little less than the average landfill depth of 6 - 10 m [9] [10], to be around 4 – 5 m. They work by foraging the top layers of these heaps of solid waste for paper, plastics, glass and metal. In most parts of the country, the waste which lies deeper in the bed is left untouched as waste-pickers leave after earning enough for the day, thus leaving huge amounts of recyclable waste to be landfilled. Sight of large amounts of paper and plastics in the decomposed material being mined in landfills is common (no experiments were done to analyze this claim). Informal rag-picking thus does not serve the entire cause of sustainable waste management. Open burning practiced by waste pickers to recover recyclable materials like metals leads to burning of rags, textiles, wood, decomposable matter, leather and rubber. 

 The Dharavi Project in the slums of Mumbai identified waste-pickers, educated them and employed them to achieve a high percentage of recycling of about 80% of dry waste

Waste to Energy in India

Waste to Energy Incineration is a proven mixed waste handling technology world over but with lesser success in countries like the US when compared to Europe and Japan due to different reasons, the most prevalent one being cheaper landfilling in the US due to larger land availability. But in the case of New York, New York pays just $60 per ton as a tipping fee for each of several million tons of trash it generates that are thermally treated at a WTE plant in Newark, NJ, while paying over $100 per ton to haul waste to remote landfills in South Carolina, Ohio, and elsewhere ¹⁴. The probability of WTE becoming economically cheaper than landfilling in India is less because of loosely implemented regulations. However, with an increasing middle class and increase in public health awareness, Waste to Energy will become an important part of Integrated Solid Waste Management in India as there always exists a fraction which can neither be composted nor recycled.

            The greatest drawback for WTE in India is its bad track record.
