Abstract
Vent structures are provided on the upper and lower sides, and lid of an organic waste cart so that wet biomass deposited in the cart is dried by convective air currents passing through the cart. The lid vent is hooded to prevent moisture from passing into the biomass. A perforated false bottom within the cart elevates the biomass above the lower vents to assure that drying air can circulated throughout the biomass.
