What is Wet Waste?

x Soiled food coversx Sanitary Waste such as napkins and diapersx Cigarette buttsx Oily food (harms the composting process)

x Watery stuff (drain away the liquid from sambhar/curry before disposing it for composting)

x Dead animals (rats, cockroaches etc.)

x Weeds and diseased plants from the garden

What is NOT Wet Waste

Oily food in atake away container Empty Take-way container

Often we find non-

compostable items are

assumed to be wet waste.

Drain the Sambhar/Rasam/curries

before disposing them for composting

Coconut Shells

(collect separately . Can be

used as fuel)

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 to home/community composter or bio-gas plant.

In apartments daily door-to-door collection of wet waste by housekeeping is a best practice
