Wet Waste Collection
Final Disposition: Composted at home or
Community Composting or use for biogas
generation. For independent houses your
municipal corporation will provide a separate wet
waste collection
Collection: Covered bin in Kitchen lined with newspaper. Tear newspaper
lengthwise to get 2 long pieces. Place them into the bin to cover the bin inner surface.
NO PLASTIC BAGS!
Disposal : Transfer daily home or community composter. In apartments daily door-to-door collection of wet waste by housekeeping is a best practice
