Separation of contraries during the treatment of biowaste prior to wet fermentation

An efficient biological treatment of source separated organic waste from household
kitchens and gardens (biowaste) requires an adequate upfront mechanical preparation. This typically includes a separation of physical, non-organic contaminants like glass, plastics, etc. which otherwise might end up in the compost or digest.

In Germany Maximum limits for such contaminants in the compost and digestate are specified. In this paper the efficiency of different treatment options for the preparation of biowaste for wet digestion processes are presented. This includes on the one hand results from trials with a waste separation press (WSP) and a further separation of still existing contaminants with hydrocyclones.

Die innerstaatliche Umsetzung des Pariser Klimaschutzübereinkommens - ein Rechtsvergleich
© Lexxion Verlagsgesellschaft mbH (8/2024)
Like all public international law treaties, the Paris Climate Accords rely on national law for their implementation. The success of the agreement therefore depends, to a large extent, on the stepstaken or not taken by national governments and legislators as well as on the instruments and mechanisms chosen for this task. Against this background, the present article compares different approaches to the implementation of the Paris Agreement, using court decisions as a means to assess their (legal) effectiveness.
