    Abstract: Disclosed is a waste processing plant and method of processing waste biomass. The plant includes a waste receiving apparatus for receiving biomass waste and processing it into a liquid stream before passing it to, anaerobic hydrolysis tanks for hydrolysis, acidification and acetylation of the stream, before passing it to, a heat exchanger for raising the temperature of the stream to a pasteurization temperature, pasteurization tanks for holding the stream at the pasteurization temperature to ensure adequate pasteurization before passing it to, and anaerobic methanogenesis tanks for anaerobic digestion of a portion of the stream into biogas. Also included is a centrifugation apparatus to separate oil from the stream, wherein at least a portion of the stream which is downstream of the hydrolysis tank(s) and upstream of the methanogenesis tank(s), and which has a temperature of above 68° C., is centrifuged by the centrifugation apparatus to remove a portion of the oil.

    Abstract: The invention relates to a device for metering an additive into a fluid, containing a valve body, a fluid inlet, and a fluid outlet. A first channel system extends between the fluid inlet and the fluid outlet in the valve body, and a second channel system extends between the fluid inlet and the fluid outlet in the valve body such that in the operating state fluid can flow from the fluid inlet to the fluid outlet either through the first channel system or through the second channel system. The valve body contains a docking element which is configured for docking a cartridge for the additive. A switchover device is provided which can be switched if the cartridge is docked such that the second channel system is fluidically connected to the cartridge when the cartridge is connected to the docking element.
