The city corporation is working on modalities to switch over from the existing centralised solid waste management project to viable decentralised schemes for the city.
Three projects were presented before the councillors at a special meeting of the corporation council on Friday. The presentations were made by the Centre for Research and Development in Health Hygiene and Environment (CRDHHE), an NGO; the Confederation of Real Estate Developers Association India (CREDAI) and the Kerala Sashtra Sahithya Parishad (KSSP).
Mayor V.K.C. Mammed Koya, who chaired the session in the afternoon, said that the project presented by CREDAI appeared to be ideal for residential apartments. Further, the Corporation would not have to incur any financial expense to implement this project.
However it was up to the Standing Committee on Health to take a final call on these projects presented by CRDHHE and KSSP, the Mayor added.
The CREDAI’s project involved the collection of segregated waste in bins called Bio- Digester Bin. The waste is decomposed through aerobic process called the bio-trigger mechanism by spraying bio culture. It is convenient to process bio degradable rejections into compost within 30 days.
This is done by depositing it in three-tier terracotta pots. The compost can be used as organic fertilizer in vegetable or floral gardens.
The KSSP modelled focussed on creating awareness on waste management, reducing garbage at households and disposal of plastic waste. It focussed on setting up kitchen bin pipe compost, vermicompost and biogas plants at households.
Composts will be set up in all households within two years. Besides, the KSSP will take steps to streamline the functioning of the waste treatment plant at Njeliyamparamba.
The project, presented by CRDHHE, emphasised on setting up aerobic compositing instead of pipe composting. The objective is to safely disposal the bio degradable waste from households or institutions at the sources itself.
This involves collecting the organic waste in bins.
The waste is turned into manure using chemically- treated husk after 20 days. The fertiliser could be used for vegetable cultivate and gardens.
The project would not only help to dispose garbage but also promote vegetable cultivation at households in the city.
