Terrace composting

It has been a few years, more than five actually, since we tried composting on the terrace at Brigade Millennium Mayflower Block. Though this very successful pilot experiment has been written about here, I realised that the process has not been properly documented, so here goes!

The objective was to reduce the waste that went out of the 250-flat apartment block. The solution for wet waste was quite obvious, on-site composting.

Those of us from the apartment block who got involved with the project did quite a bit of research to arrive at a sensible, scalable model keeping in mind the existing infrastructure and constraints in the block. We visited a few working sites, read about various methods and engaged with waste management experts and service providers. With the help and guidance of Mr C. Srinivasan, a member of the Supreme Court of India’s Committee on Solid Waste Management, we decided on a method that overcame the lack of space on the ground. The terrace on the 15th floor was identified as a suitable location. Apart from a trolley that was specifically designed for the purpose, the method uses only natural resources – air, water, sunshine, manpower and bacteria present in cowdung/curd.

4 ft x 3 ft x 3 ft. Fabricated with metal flats. Fitted with wheels for portability. Cost in 2010 – approx Rs 4,500.
