Abstract: Lavatory for connection to a composting container (1) or a sewage pipe forming part of a sewage system. The lavatory has a seat part (11), a lid (12) adapted to the seat part, and a hollow support body (13) supporting the seat part. The support body (13) surrounds or forms an inner duct through which fecal matter passes to the container or the sewage pipe. The rear wall of the duct slopes backwards from the seat part (11) in the downward direction so that it forms an angle (&agr;) with the vertical.

Abstract: Composting device for night soil and other biodegradable material, comprising a receptacle for receiving the material to be composted and on the bottom of which a starting bed is to be spread out. The receptacle comprises an inner, seal-tight lining in the form of a sack (10) made from a flexible, liquid-impermeable material and a carrier (1) intended to support the sack. The sack is constructed with liquid drains (14) for the drainage of liquid which is separated from the composting material. The carrier (1) and the sack-lined receptacle are arranged such that they can be transported as a unit to a depot after the sack (10) has been wholly or partially filled. The bottom of the carrier (1) is constructed with openable hatches (8), which allow the sack (10) with its contents to be deposited in the depot through the said bottom when the carrier (1) is lifted.

Abstract: Arrangement for collecting and composting night-soil and other biodegradable material, comprising a space (23) in which a starting bed (29) has been spread out in order to accelerate the breakdown of material (30) which is dropped down onto the starting bed. The space (23) is lined with an inner layer of a flexible, liquid-impermeable material forming a sack-like container (8) which is open at the top. The starting bed (29) is arranged in the sack-like container, and the arrangement comprises members (40) for pressing the upper edge portion of the container against a ceiling (36) which is located under the floor (32) of at least one overhead toilet and is provided with at least one opening for attachment to a toilet bowl. The sack-like container (8) is designed to enclose the material (30) while the latter is being broken down, and the container comprises members for conveying liquid, which has been separated off from the material, via a screen arrangement (31).
