COIMBATORE: Following up on the clean city drive, specifically for the World Classical Tamil Conference, the Corporation plans to rid the commercial areas in the city and places where shops are located in residential colonies of garbage.

The civic body has made a fresh appeal to traders to store waste only in bio-bags (biodegradable bags) and not dump it along roads, into the drainage or in open spaces such as reserved sites.

“We spoke to the traders on Thursday on the need to use the bio-bags. They were asked to store the waste in these bags and hand these over to the Corporation’s conservancy workers,” Mayor R. Venkatachalam said.

Apart from the usual garbage removal at 6 a.m. across the city, another shift at 9 a.m. would be introduced specially for the traders.

New shift

The Mayor said the shops, especially the ones that sold fish and meat, would not have much waste as early as 6 a.m. Therefore, the new shift would be introduced.

“Unless we put in place a disposal system that meets their needs, the traders also may find it difficult to adhere to the Corporation’s orders. At the same time, the traders will have to go by the system once it is in place,” the Mayor said.

“In order to spread the message wider, we plan to hold meetings with traders at the zone level, involving the Mayor, Corporation Commissioner, Deputy Mayor, Health Committee Chairman and other officials, he said.


‘City Clean Campaign’ in July

To remove plastic waste within Nellai Corporation limits

TIRUNELVELI: Tirunelveli Municipal Corporation, which has identified 124 places under its jurisdiction where ‘waste plastic mounds’ have been created by its residents, has decided to involve its entire workforce along with volunteers drawn from schools and colleges in its ‘City Clean Campaign’ to remove this highly hazardous materials to be destroyed safely.

After the district administration and the Department of Environment decided to impose a ban on the production, sale and use of non-recyclable non-degradable plastic materials, particularly, plastic bags, serious steps were initiated to clean up the already piled up plastic wastes by involving India Cements Limited (ICL) in this noble exercise.

As per the memorandum of understanding signed with ICL, the urban local bodies of Tirunelveli, Tuticorin and Nagercoil should collect the plastic wastes being generated in their respective areas and send it in the lorries to the premises of cement manufacturing unit, where the hazardous non-degradable materials would be finely shredded to be used as supplement fuel along with the regular fuel, coal.


Subsequently, the ICL management spent over Rs. 1 crore for making some modifications in the machineries and installed equipment to make this process effective.

Even as this exercise is going on, the corporation has planned to put an end to the creation of plastic heaps under its jurisdiction while cleaning the existing stacks of plastics.

As per this new initiative, the plastic waste dumped at 124 places in various places under the Corporation will be removed during the ‘City Clean Campaign’ to be jointly organised by its 700-odd conservancy workers and over 1,800 students and volunteers drawn from various schools, colleges and also from the residents’ welfare associations.

“This camp will be conducted in the first week of July on a particular day simultaneously across the corporation to clean the plastic hillocks. After the conduct of this campaign, we’ll initiate very stern action against those who produce, sell and use the non-degradable plastic products as production, sale and use of these hazardous materials within corporation limits have been banned. Residents should hand over plastic waste only to the conservancy workers hereafter,” said Commissioner N. Subbaian.


Erode: Dumping of waste in irrigation channels goes unchecked

Farmers blame district authorities for inaction

ERODE: The dumping of solid waste, including huge amount of plastic waste, in the irrigation channels and sewers in the district remains unchecked for long.

A large number of commercial establishments particularly eateries and a few irresponsible citizens dump solid waste in almost all the sewers in the town. In the recent rains, almost all the open sewers in Erode town overflowed and flooded residential areas.

Apart from sewers running in the town, solid waste is being dumped in large quantity in the irrigation channels, thus killing them slowly.

“A large number of farmers depend on these channels to irrigate their fields. They have taken this issue to the notice of senior officials on several occasions. But they are yet to witness a positive response from the officials,” people say.

Farmers had even represented this issue during their monthly grievances redressal meeting.

“But our grievance is yet to be redressed,” farmers lament.

A number of irrigation channels passing through the town have now become big sewers emanating foul odour and a fertile breeding ground for mosquitoes.

The district authorities and the Erode Corporation continue to turn a blind eye over this issue.

“Each time we approached the officials in the district administration and the Corporation, they give us assurance that they would initiate appropriate action. But no concrete action has been taken up so far to put an end to the indiscriminate dumping of solid waste into the water carrying channels and sewers,” people charge.


New process to treat organic waste in effluents

Anna varsity to soon join hands with firms for commercialising the project

In a bid to reduce water pollution caused by industrial effluents, the Centre for Environmental Studies, Anna University, has developed a special consortium of microbes that could be used to treat organic waste even in effluent with high salinity level.

The Centre’s director A. Navaneetha Gopalakrishnan said the Centre, which had recently patented the process, would soon join hands with firms to commercialise the project.

At present, several industries release raw effluent into waterways, including the Cooum river, as the microbes now used in the treatment process cannot digest organic waste owing to high total dissolved solids (TDS) level.

The new process was tested in waste water, which has TDS level ranging between 50,000 and 65,000 mg per litre. The microbes used in aeration process helped in treating the organic waste, he said. N. Vasudevan, professor at the Centre for Environmental Studies, said the process would be more efficient than that used in sewage treatment plants for organic waste removal. It is economical than the energy intensive treatment process used in industries.

Moreover, the salt content in the waste water could be recovered through evaporation for use as raw material in alkaline industries. Chlorine gas, which is used as disinfectant in water treatment, could also be generated, he said.

Stop dumping plastics in canals – EcoWaste

Green advocates appealed to the public Sunday to stop the disposal of plastic bags along waterways after heavy rains again triggered flashfloods in the metropolis last Friday.

As the country braces for severe storms and accompanying floods, the EcoWaste Coalition asked the public to prevent disposing of plastic bags that clog waterways especially during the rainy season.

EcoWaste coordinator Rei Panaligan said the flashfloods in some portions of Metro Manila last Friday was reminiscent of the floods caused by tropical storm “Ondoy” last year.

The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) earlier warned that a repeat of storms “Ondoy” and “Pepeng” is likely with the prevalence of the La Niña event this year.

Based on the US National Weather Service (NWS), most climate models predict a transition from El Niño by June to the onset of La Niña conditions by July to September 2010.

EcoWaste also noted that, “carelessly thrown plastic bags block the drainage systems and waterways and will find their way into the country’s biggest ‘landfill,’ the Manila Bay, causing massive marine pollution.”

“Let us not forget the lessons of Ondoy and together cut our waste size, starting with single-use plastic bags,” Panaligan said.

The group urged Filipinos to reject all forms of littering and dumping, reduce trash and make it a habit to separate discards at source for reusing, recycling and composting.

A study by EcoWaste and Greenpeace show that synthetic plastic materials constitute 76 percent of the floating trash items in Manila Bay, with plastic bags comprising 51 percent; sachets and junk food wrappers, 19 percent; Styrofoam containers, five percent; and hard plastics, one percent.

The rest of the rubbish found in Manila Bay consisted of rubber (10 percent) and biodegradable discards (13 percent).

Another study published in 2009 by the US-based Ocean Conservancy revealed that 679,957 of over 1.2 million pieces of marine litter of various types that were gathered in seaside areas during the 2008 International Coastal Clean-Up Day in the country were plastic bags.

Waste Management: Kulithalai model fetches laurels

KULITHALAI: Profitable conversion of civic waste into eco-friendly vermicompost has made the “Kulithalai model” in solid waste management a head-turner in civic body circles nationwide.

With its synergetic approach to profitable disposal of solid waste, the Kulithalai Municipality in Karur district has secured a grant of Rs. 40 lakh for improving its facilities and furthering its agenda.

Kulithalai municipality’s effective schedule of segregation of bio-degradable waste and others at source, door-to-door collection of garbage in 19 of the 24 wards covering 5,245 households in the civic area and profitable disposal of the 3.5 to four tonnes of garbage gleaned every day has come in for wholesome praise in municipal circles.

Pioneering work in converting the civic waste into vermin compost is being undertaken zealously at the Sathyamangalam compost yard spread over 9.2 acres. The bio-degradable waste is processed through the wind row pile method and circular heap method for pre-digestion involving either cow dung slurry, press mud and effective micro-organism solution, according to Kulithalai Municipal Chairman A. Amuthavel.

The pre-digested waste gets value addition through the tank method or heap method or brick method for harvesting vermi compost suitable for all crops. Demand for the civic body’s vermi compost is high, claims Mr. Amuthavel and already more than 4.5 tonnes has been sold in the past few months. Another six tonnes are ready for sale and for own consumption.

The aim is to generate revenue to the tune of Rs. 1 lakh per month through vermin compost sales to make the venture self-sustainable, he adds.

Plans are under way to have a green cover spread over five acres at the yard for which the Forest Department has given 500 “Pungan” saplings and another 1,250 “Kumizh” saplings have been procured.

What’s more, as inter-crop, jack saplings are to be planted. Along the perimeter of the yard, over 1,000 casuarina saplings will be planted to act as wind barriers. Drip irrigation is to be installed for micro-irrigation management, Mr. Amuthavel observes.

Mr. Amuthavel acknowledges the technical support Exnora International has been providing for the project.

Stating that the stakeholders’ involvement is the key to the success of Kulithalai Model, coordinator Vijay Anand of Exnora says that they are just facilitators and provide capacity building to the civic body and the synergy has brought laurels.
