Community biogas plants set up in public markets, schools and major public spots in the city are the latest casualties of corporation's ill-maintenance of waste management units.

The latest consolidated report on community biogas plants prepared by the health wing points out eight out of 14 such plants are currently not functional and importantly corporation has not framed annual maintenance contracts (AMC) with any of the 14 agencies which installed the bio gas plants.

A variety of reasons have been enlisted for non-functional bio-gas plants. The community bio-gas plant at Peroorkada which was installed to process 2 tonnes waste a day is out of order due to damaged pulverizer.

The plant at Kazhakkoottam with a capacity to process 1,500 kg per day, became dysfunctional because of overloading. The biogas plant at Sreekanteswaram Park with a capacity to process 1,200 kg per day is unable to process waste because of lack of sufficient quantity of waste. While another such plant installed at Sree Chithra Home here is also dysfunctional due to overloading, the report notes.

The health committee's failure to renew AMCs and recruit trained personnel to maintain community waste management units had led to the failure of 236 aerobic bins in the city. The civic body had spent close to Rs 1.25 crore to set up community biogas plants in public spots, schools and markets. Even the community biogas plant at Palayam, which was the first high capacity plant to be launched by the city corporation in 2012, also shows the status 'Not functioning'.

A contractor, who had a horrid time running from health circle office to main office to receive his installation cost and then with requests for renewal of AMC, says that the corporation has never been keen on proper maintenance of community bio gas plants. "At the time of installation, operation and maintenance are covered for a mandatory period of two years, after that period, no one has cared either to renew the contract or to make sure that the plant is maintained properly," says the contractor.

It takes corporation Rs 1.85 lakh to pay for AMC and the health committee has not shelled out money for AMCs for any of the community biogas plants. In March 2016, the corporation had called for tenders to clean the community plant at Sreekanteswaram. The biogas plant with a capacity of 1,200kg was set up in 2013 at a cost of Rs 15 lakh. The plant had stopped functioning for almost a year after the corporation staff had failed in ensuring that only segregated waste reached the plant.

Lack of segregation and mismanagement has cost corporation not just the money but also has posed questions at the viability of decentralised waste management without proper monitoring. At Manacaud, the health officials had cited that they received wrapped covers of sanitary pads and even stained diapers from households.

Processing of market waste has also been derailed after community bio-gas plants had failed. The report shows that except for Sreekaryam market, the community bio-gas plants at Manacaud, Palayam, Peroorkada,Vattiyoorkavu, Nalanchira and Kazhakootam do not function anymore.

In the meantime, the civic body has cleared 138 loads of waste dumped in public places even as most of the community waste management plants have been is disorder for almost a year.
