Abstract: The invention relates to a method for producing a form-cut object made of foam. The invention is based on the aim of refining a known method for producing a form-cut object made of foam in that it also allows the precise creation of complex shaped form cuts in the foam. This aim is achieved by the method according to the invention in that the first preliminary version of the object in the region of a first form or contour cut is provided with a (second) form cut, which is superimposed on the first form or contour cut and extends down to larger depths than the first cut. Preferred application areas of the claimed method and the resultant objects made of foam are pillows, for example.

Abstract: A system for processing sewage into vermicompost includes a holding tank for receiving and initially processing the sewage. A treatment tank, connected to the holding tank by a first pipe, is used for treating the initially processed sewage from the holding tank to ensure optimal pH, percent of solids, and electrical conductivity of the sewage. A distribution tank, connected to the treatment tank by a second pipe, is used for heating or cooling the sewage from the treatment tank as necessary. A distribution apparatus, connected to the distribution tank by a third pipe, distributes the sewage to a vermicular environment, wherein the vermicular environment contains a plurality of worms which digest the distributed treated sewage into vermicompost.
