Abstract:

An aerobic-anaerobic composting device and method of composting organic waste materials. The composting device disclosed is a free-standing rotatable wheel which has an open mesh material on its exterior sides and ends. After the organic waste material is placed in the wheel, a removable cover is placed over the open mesh material on the sides of the wheel and the wheel is rotated periodically to mix and aerate the contents with a tumbling action. The cover retains the material in the wheel and also protects it from the weather. Fertilizers or other chemicals of high nitrogen content may be added to the waste material in the wheel to promote its decomposition. After the composting has been completed, the cover is removed and the composted material is discharged by rotating the wheel. For anaerobic treatment, the wheel is not rotated and a second cover is placed over the material in the wheel and the ends of the wheel are closed to restrict the flow of air. After such treatment, the inner and outer covers are removed and the contents of the wheel are discharged, as required, by rotation of the wheel.
