Corporation moots 30 litter-free roads for city

Staff Reporter

Residents of all zones in the city can soon look forward to two litter-free roads.

All 15 zones have been asked by the Chennai Corporation to declare two roads for which all efforts will be taken to ensure they remain clean. Some zones have already started work on the areas. LB Road and Kalki Krishnamurthy Salai are among the roads which will soon have boards declaring the stretch a ‘litter-free zone.’

A few zones have planned to use the services of at least 15 workers to sweep the roads three times a day, with the workers likely to be made accountable for deficiency in sweeping operations. Sweeping is normally done only once a day on the city roads.

The Corporation plans to have workers removing trash as soon as a resident is spotted disposing the waste on the roads.

This is expected to educate residents and prevent them from littering roads. The Corporation has also planned to set a precedent for other parts of the city by sprucing up the 30 roads and their footpaths. Illegal banners or hoardings will be removed on such stretches immediately after they are erected.

“All roads in the city should be clean. We are used to spitting on the road. The move will be successful if the Corporation gets the cooperation of the people,” Ahmed Sirajuddin, a resident of Perambur, said.

Many zones of the civic body have also decided to use the services of private agencies to remove construction debris on the roads. Kodambakkam zone has invited bids from private agencies for the clearing of debris on roads in each of the wards. As many as 8,000 tonnes of construction debris are found on the road every week.

The civic body is also planning to impose new conditions before a demolition order is issued for a building.

Intermittent power cuts are no longer a barrier to adequate illumination on a small stretch of East Coast Road. The Mamallapuram town panchayat’s move to install a bio-gas plant has not only helped provide continuous lighting and save money but has also become a model for study as is evinced by visits by students to the plant.

The 100 cubic metre bio-gas plant, installed at a cost of Rs.20 lakh in a compost yard, uses 500 kilograms of bio-degradable waste to produce 40 cubic metre of bio-gas every 12 hours. This is used to run a 10 kilowatt (KW) generator that produces 8 KW of electricity which powers 30 street lights. Each of the lights — a 96 watt compact fluorescent bulb — has been functioning from 6 p.m. to 6 a.m. without any interruption for the last three months.

On an average, around 5,000 kilograms of garbage is generated daily in areas under the civic body. Prior to the tapping of bio-gas-generated power, the civic body used to shell out Rs.6,600 a month to the State electricity authorities for powering the 30 street lights. Now, the total cost of operating them has come down to only Rs. 600.

Civic body officials said the bio-degradable waste generated by various establishments would be more than sufficient to operate 3 bio-gas plants. The electricity generated from such plants would be sufficient to run around 60 to 90 more streetlights, they added.

Schools seem to have chosen the plant as a regular stop on education trips. Recently, a batch of students from a school in Kilpauk visited the plant on their way to Mamallapuram.

Get gold coins, watches in exchange for trash

Staff Reporter

The Chennai Corporation will collect 48 tonnes thin plastic waste from residents, every day. The civic body has announced rewards, ranging from half-gram gold coins to wrist watches, for residents every month in each of the 200 wards in the city.

However, the residents will not get money for the plastic waste collected, said Mayor Saidai Duraisamy on Friday at the Corporation council meeting.

Each of the 200 wards will have a dedicated worker to collect thin plastic waste from residents on Wednesdays and Saturdays between 9 a.m. and 5 p.m. The residents will get a token after handing over of the plastic waste to the engineers concerned.

One resident in each ward will be selected every month for distribution of the gold coins. Five other residents will receive wrist watches each. The civic body will incur an expenditure of Rs. 18 lakh for three months on a pilot basis.

The amount of thin plastic waste dumped per day in the city is 96 tonnes. This is two per cent of the total waste generated in the city.

The illegal sale of thin plastic bags was brought under control after more than 300 registered units and hundreds of unauthorised units were regulated after the civic body’s intensive drive last year.

Plastic bags with less than 40 micron thickness have been banned, as per the provisions of the Centre’s notification on Plastic Waste (Management and Handling) Rules, 2011.

However, retail outlets in the city continue to procure plastic bags with thickness of less than 20 microns.

The bags are transported from other parts of the country. The civic body proposes to focus on source segregation as it is unable to control the movement of illegal plastic bags.
