Revision as of 09:41, 27 August 2021 by Lars Krause (talk | contribs)
Primary processing of biowaste results in intermediate chemicals and/or materials which will then go into the secondary processing after which the final product is obtained. used to prepare raw materials so that they can be processed by core technologies.
