According to reports, now it’s the turn of apartment complexes in the city to set up biogas plants. In apartments, biogas plants are being set up primarily for treating waste from kitchen.
Though there are different mechanisms for treating waste in apartments, many of them have been finding it difficult to address the issue completely. While some of the apartments treat bio-degradable waste using biopots and bio-bins, the corporation collects from others.
According to firms which provide service and technology for setting up biogas plants, apartments in the city have been increasingly approaching them to set up plants. The cost of the plants varies between Rs 3 lakh and Rs10 lakh, depending on their capacity. “We set up a biogas plant in our apartment a year ago after the corporation failed to collect waste regularly. Now we are able to process bio-waste generated in 24 flats in the apartment complex,” said Panampilly Nagar Infra Hamlin Owners’ Association treasurer Bino Charley. However, she said as biogas produced was not sufficient enough for apartment dwellers it was used by security staff of the apartment for cooking.
Johny Joseph, a scientist with the Hyderabad-based Indian Institute of Chemical Technology (IICT),feels that biogas plants are best suited for treating degradable waste in apartments.
“The field trial of the technology, which was developed after a research that spanned more than four years, has already been completed. The technology was developed after studying those used in European countries. It has a process efficiency of 95%,” said Joseph.
He added that he had received over 15 requests from apartments in the city.
“We will install biogas plant in our apartment in two weeks. We have decided to set up the plant as disposing of manures had become a problem, if it is converted to manures by using bio-pots,” said Kent Illam and Gopuram Owners’ Association secretary Anup Mathew.
Industry sources said that some of them had been installing plants, which were not sufficient enough to treat bio-waste generated, for availing government subsidy.
