It actually depends in which environment it degradates, Here`s the time of biodegradation in marine environment:
General paper 1–3 months Paper towel 2–4 weeks Cardboard box 2 months Cotton cloth 5 months Plastic coated milk carton 5 years Wax coated milk carton 3 months Tin cans 50–100 years Aluminium cans 150–200 years Glass bottles Undetermined (forever) Plastic bags 10–20 years Soft plastic (bottle) 100 years Hard plastic (bottle cap) 400 years
