‘Bio-Chest’ to augment MCT’s zero garbage initiative

By TheHindu on 19 Aug 2017

To make better use of organic waste produced from vegetable markets in the temple city, the Municipal Corporation of Tirupati (MCT) has introduced two ‘on-site and in-vessel organic waste composters’ at the Rythu Bazaar and the Indira Priyadarshini Vegetable Market.

The 'Bio-Chest' units, with capacity to handle 500 kg per day, can convert both dry and wet waste into compost within 21 days. This facility, officials said, would reduce the burden of shifting the organic waste to dumpyards or to centres following traditional composting practices.

“Everyday municipal workers feed the unit with the generated organic waste and microbial culture. This goes on in a cyclic process and the initial result i.e., the compost, is obtained after 21 days and can be collected subsequently,” maintained a senior municipal official, while speaking to The Hindu.

He said the facility would augment their focus on the ‘zero garbage’, which would involve making the best use of waste produced at a particular site, alongside eco-friendly initiatives.

Clean, compact

With an input of 10 tonnes of organic waste during the cycle, more than three tonnes of compost would be generated. The 'Bio-Chest' units, installed by Tamil Nadu-based VNS Enviro Biotechq, would take less space at the site and will not have the problem of bad odour as the entire composting is done within the vessel/unit. “It is also free from houseflies and mosquito menace,” maintained VNS Enviro Biotechq's CEO and Managing Director S. Nagarajan. “It can also be used by local bodies, universities, industrial canteens, temples etc., where there is a possibility for effective utilisation of organic waste,” he said.
