<p>PCT No. PCT/FI89/00163 Sec. 371 Date Feb. 12, 1991 Sec. 102(e) Date Feb. 12, 1991 PCT Filed Aug. 31, 1989 PCT Pub. No. WO90/02720 PCT Pub. Date Mar. 22, 1990.The invention relates to a composting device for toilet and foodstuff waste to be used in connection with a toilet. In the device according to the invention, the upper portion of a rotating compost container 6 provided with a filtering floor 9 is divided into four sections to keep apart compost materials of different degree of compositing. The compost container is positioned partialy within the toilet room so that the toilet seat 5 is positioned immediately or substantially immediately above the cover of the composting device. In this way, the natural aeration will not cause the smell of the compost material to enter the toilet room when the cover of the toilet is opened. In the composite container, the waste is aerated both from above and from below. The circulation of air is arranged to take place naturally so that it flows all the time upwards. The air flow causes the liquid 10 on the bottom of the container to evaporate and takes the evaporated liquid with it, thus keeping the above composte material humid. Surplus liquid is discharged from the central area of the bottom of the compost container. This enables the collection of liquid at one point by means of a single-wall rotating container.</p> |
