Solid waste experts have criticized Bengaluru Mayor’s proposal to make kitchen pulverisers mandatory for all new households and hotels. Few days ago, the Bengaluru Mayor, R. Sampath Raj had told that eventually pulverisers would be made mandatory in their kitchen sink for all new households and hotels to reduce the amount of garbage generated. An online campaign called #KitchenPulveriserBeda has already been launched against the mandatory installation of pulverisers or food crushers in the city.
According to solid waste experts, households need 10-20 litres of fresh water a day to pulverise and flush kitchen waste in the sink which in a water scarce city like Bengaluru would put additional burden for water thus creating fresh problem for the city to tackle. Some also feel that the proposal if made mandatory would affect the functioning of sewage treatment plants (STPs) also. According to them STPs in the city are not designed to handle this type of waste water and may become dysfunctional.
As most of Indian foods have fats and oils, if they are flushed down the drain they may gradually settle down on the lining of the drainage pipes which will eventually clog them. This will only increase the cockroach menace in the drains, which poses a real threat of spreading several diseases, experts warned. Instead, ecologists suggest making composting on premises mandatory would be a better idea. They suggest adopting the Alappuzah model where the local civic body gives a 50% subsidy for bio-gas units and 90% subsidy for in-situ composting units.
