Many tech – savvy professionals have made it their calling to harvest precious metals (literally) and moolah from garbage, writes Rahat Bano Garbage is gold. A lot of electronic waste, including your cell phone, carries precious metals like platinum and gold. And many tech – savvy professionals have made it their calling to harvest it.
The raw material is ample – 700,000 tonnes of electronic waste every year, according to an expert. “From a 40 - foot container – board of printed circuit board, chemical engineers can recover about 10kg of gold,” says S. Sampatth, president of Hyderabad president of Hyderabad – based Samki Teck Resources, which turns plastic and rubber waste, such as empty wafers packets, poly bags, stickers and cello tape, into resources. It converts inorganic waste into energy (diesel oil) through reverse engineering.
“After computer science, waste management will be the future,” declares Sampatth, a civil engineer from IIT Madras. Experts explain how somebody else’s waste can become consumable for others – as compost, biogas, or diesel oil.
“We waste too much of waste.” Says Sampatth, “In India, 300 grams of waste is generated per capita per day. That comes to about 40 million tonnes per year. Of this, about 5% is plastic and rubber. Between 1.2 million to 1.5 million of this plastic and rubber goes to land fills or lies scattered on the streets.” Sampatth reckons that from this 1.2 to 1.5 million tonnes of waste, waste management companies can generate about six lakh tonnes of diesel per year, which can be used to run a truck for six crore km.
That’s just one of the alluring possibilities in India’s mounting landfills. Companies are tapping into more waste for business. Sampatth says his company is building a full – fledged plant “about which we will make an announcement in about two weeks in Hyderabad.” He adds, “if you set up 500 such units, it will mean about 500 new entrepreneurs, employing about 500-1000 engineers between them”.
Organic waste is a much bigger business proposition – it constitutes 35% of all garbage generated in India. Water management, construction waste and debris (30-40%) and hazardous waste, including bio-medical waste management, says Mumbai – based Amiya Kumar Sahu, president, National Solid Waste Association of India an convener/coordinator, NSWAI-Environmental Information System or ENVIS, a result of its tie – up with the Union Ministry of Environmental and Forests.
“Then there is huge scope for recycling of batteries, tube lights and
CFLs, which requires skills professionals,” says Sampatth. “There
is a lot of potential in this field, especially in a developing country,”
A lot of waste management work is being done by private and non – governmental organizations. There has been some move in government set – ups towards professional garbage management. For example, through a public private partnership, Mysore City Corporation is reportedly with diesel, kerosene, wax and perfume as by – products.
Once upon a time, this didn’t happen. Before 2000, when Municipal Solid Wastes (Management and Handling) Rules came into effect, civic bodies didn’t even keep an inventory of garbage, says Sahu, who wrote the first draft report on the rules submitted in 1997. The 2000 rules laid down compliance criteria and the procedure for managing and handling municipal solid waste in cities and towns. The rules also said civic authorities would “adopt suitable…technologies to make use o wastes so as to minimize (the) burden on (the) landfill.”
Apart from such domestic developments, the international carbon credit market
has had a positive spin – off, too. Recently, Municipal Corporation
of Delhi earned Rs. 5 lakh worth of carbon credits for one of its plants.
Ketan Mehta, owner of Ecosense Labs in Mumbai, says their business picked
up about two – three years ago as the carbon credit market became “liquid
and fluid”. Ecosense, involved in R&D of solutions using biotechnology,
sells products including those that hasten the conversion of biodegradable
waste into compost, without producing methane, a green house gas. “With
carbon credits, the profitability and viability of these (waste management)
projects has tuned around.” The profit margin changed from eight to
15% to about 12% to 15%, he says.
Surely, there’s some profit in this field.
