Organic Waste Converters in Bandra-Kurla Complex, Mumbai.

Food courts, hotel kitchens, the convention centre and staff canteens make BKC a heavy producer of wet waste on working days. MCGM expects bulk waste generators to compost or digest their wet waste on site, and a large commercial plot usually falls in that group. The difficulty is space and smell in a basement that also holds parking and plant rooms. We weigh the kitchen waste before choosing capacity, place the unit with ventilation and a clear route for bins, and find a use for the compost.

The Bandra-Kurla Complex was laid out by MMRDA on low, marshy ground between the Mithi River and Mahim Creek, and it still sits with water on two sides. Over four decades it has filled with bank headquarters, the stock exchange, consulates, a convention centre and hotels, set on wide plots with podium parking below. Few people live here; tens of thousands arrive each weekday by road, suburban rail and now the metro. Underground works for the high-speed rail terminus and fresh towers rising on the last vacant plots keep parts of the district under construction. MMRDA, not the municipal corporation, plans it.
