The Mamallapuram branch of Adyar Ananda Bhavan generates 30 kg. kitchen waste a day. A seaside resort across the East Coast Road accounts for 10 times more of food waste. There are 700 odd eateries in this tourist town. Till about five years back, food waste from Mamallapuram restaurants and hotels wound up at the municipal landfill.
And then, came a bio-gas plant that converts kitchen waste into electricity. I don’t know who made the first move, but Vivekananda Kendra - a Kanyakumari based NGO - designed and set up this plant, on a reclaimed patch of the municipal garbage dump yard. The waste-to-energy plant is run by another NGO – Hand-in-Hand.
Mr M Raja of Hand-in-Hand who conducted us around the plant - a group of OMR Greens members from Padur - explained at length the waste-to-energy conversion process, from door-step collection of food waste to transmission of the converted electricity that powered 25 street lights. Over 40 waste collectors are engaged; and their remunaration is covered by the collection charges paid by the eating houses. A minimum levy for kitchen waste collection is Rs.50 a month and the chrages vary in accordance with the quantum of food waste collection.
The Mamamallapuram waste-to-energy plant is a collective enterprise, of several stakeholders. The plant, designed by an NGO, and located on panchayat land, is run by another NGO, with monthly contributions by eateries. The 10 kilowatts generator running on bio-gas produced by Kirloskars, costing Rs.20 lakhs (at the 2008 price level), is a donation from Sweden. Under the renewable energy programme the town panchayat is eligible to Rs.4 lakh subsidy.
Mr Raja, so knowledgeable on so many aspects, couldn’t, however, tell us the one thing we needed to know - the unit cost for producing power from kitchen waste. OMR Greens would want to sell this waste-t0-energy proposal to Padur panchayat and other stakeholders. Ideally, there should be a waste-to-energy unit for every panchayat and in setting it up all stakeholders in the neighbourhood need to be involved - residents, other individuals and institutions generating waste, property developers responsible for mushrooming residential high-rises , and the panchayat.
A bio-gas plant developed by Bhaba Atomic Research Centre (BARC) lends itself to decentralized waste disposal system. For a plant with capacity to process one tonne waste daily requires no more than 300 sq.ft. of land. And a tonne of bio-degradeable waste can produce 25-30 kg. of methane, about 150 kg. carbon dioxide and nearly 60 kg of organic manure. Besides kitchen and veg. market wastes, and those generated in abattoirs, the BARC bio-gas model can take in even hazardous biological sludge.
The plant, they say can be operated by unskilled workers such as rag-picker Ramesh and his folks at Padur . All they require is one-month training.

This milestone on Sathy Road says Chamarajanagar is just 10 km away. From here we drove past scores of slaughtered trees all the way to the town. Amputated tree trunks on the roadside bore mute witness to an officially sanctioned havoc to green cover.
This stretch of the road close to Chamarajanagar town has apparantly been left untouched. Or could it be because the timber contractor, working his way towards the town from the sixth milestone, has yet to make it here ? Whatever the reason it was refreshing to see a stretch of road so well shaded by the lofty spread of decades old roadside trees.
If axe-men have their way, this shaded stretch may become a memory before long.
We took this picture from inside a car so as not to ‘distract’ workers of the timber contractor, who may not be appreciative of our amateur camera work.
Elsewhere, logs from a freshly slaughtered tree await transport to saw mills and carpentry shops.
You could do a 1000 words on this picture. But who needs words when the chopped trunks can speak. Road-widening is cited as an obvious explanation. What is often not so obvious is that a minor fortune some people stand to make by lobbying for widening roads that are rich with old avenue trees.
Telltale remains of a chopped tree on the left of the big one suggest that road-widening may well be a pretext for converting decades old trees into high value timber. In many cases trees that got axed could have been saved, with marginal realignment of the stretch to be widened. But then saving trees fetch no money. And these are sturdy old trees, on which there is a fortune to be made by bringing them under the axe.
