Abstract
The present invention relates to a composting device for composting organic waste, specifically animal and vegetable household waste. The device consists of a container having four rectangular sides, a base and a removable, reversible cover. The container is provided with a sealable compost extraction opening disposed on a front side of the container near the base. Ventilation openings are provided in the sides. One surface of the cover and front side of the container is painted dark to absorb sunlight and heat the interior chamber defined by the container. The opposing side of the cover is painted white to substantially reflect sunlight. The cover is removed and waste is added to the container through the top. Worms and microorganisms provide a way for degrading the waste into compost, which is removed through the extraction opening adjacent to the base for recycling. The temperature in the compost may be adjusted by increasing or decreasing absorption of sunlight. The temperature gradient thus formed in the container draws air through the ventilation openings and into the container to provide ventilation for the composting waste. In one embodiment, the composting device is provided in the form of a kit for home assembly.
