Build a Vermicompost Bin
Red wrigglers eat their body weight in kitchen scraps every single day. A 60-litre bin can process 1.5 kg of waste daily — enough for an apartment of four.
Bin design
Two stacked 60 L plastic crates with 5 mm holes drilled in the bottom and lid. Top crate holds worms; bottom catches drainage (vermiwash, a free liquid fertiliser).
Choose the worms
Eisenia fetida (red wriggler) is the only worm that thrives in confined bins. 500 g of worms cost Rs 400-600 in India.
Feeding schedule
Bury veg scraps under bedding. Avoid citrus, onion, spicy food, dairy, meat. Feed once every 2 days at first; scale as the colony grows.
Harvest castings
After 90 days, push everything to one side, add fresh bedding and food to the other. In 3 weeks worms migrate; scoop out the dark castings on the empty side.
