<p>Device for closed or partly closed composting, where the decomposition can proceed at the proper temperature, under aerobic conditions and under proper mixing of the material, which is cheep, and which is easy to use. The device comprises a container (11) intended to roll, and said container is provided with gables (13,13') and a mantle face (14) which is air permeable and has an inner hard-wearing layer (17), an outer protective layer (18) and can have an intermediate isolating layer (19). The gables (13, 13') consist of a stiff and thick material and can be isolated. The mantle face (14) is preferably provided with an opening (20) for entering the material for composting and also for emptying of the ready composted material. Mixing of the material can be done e.g. by rolling the container 11 from one entering place to the next where the cover (21) can be opened. To facilitate the usage of the container (11) this can be provided with two or more rolling rockers (23,23'). In one design the container (11) is comprised with two ore more compartments (15) separated with walls.</p> |
