NOVELTY - A composting unit comprises wheeled mobile waste container having base (16), side walls and lid (18), and defining an internal volume (20) into which material for composting can be placed. The internal volume is free from internal support structures, and the lid is pivotable to enable material to be introduced into and removed from the internal volume. The container can be tilted to facilitate removal of material from internal volume. An electric air compressor (50) is arranged to continuously inject compressed air at greater than or equal to 200 mbar directly into the internal volume.    USE - Composting unit for organic materials.    ADVANTAGE - The composting unit enables economical deployment of decentralized high-pressure accelerated composting solution. This brings technology closer to organic waste rather than transporting the waste over long distance to technology. The reduced scale and minimum energy consumption allows this composting unit to work under grid connected alternating current conditions or under battery powered direct current system, e.g. solar powered system.    DETAILED DESCRIPTION - A composting unit comprises wheeled mobile waste container and electric air compressor (50). The container has base (16), side walls and lid (18), and defines an internal volume (20) into which material for composting can be placed. The internal volume is free from internal support structures, and the lid is pivotable to enable material to be introduced into and removed from the internal volume through an aperture at upper end of container. The container can be tilted to facilitate removal of material from internal volume. The air compressor continuously injects compressed air at greater than or equal to 200 mbar directly into the internal volume through a drainage aperture formed in the base of container. The drainage aperture serves as an air inlet to the container when connected with the air compressor and as a drainage outlet for liquid evacuation when not connected with the air compressor. An INDEPENDENT CLAIM is included for decentralized composting using the wheeled mobile waste container, including placing waste material for composting into internal volume; supplying compressed air continuously into the internal volume; composting; and removing compost.
