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
