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.

Biochemical pre-treatments

Enzymatic (in vitro)
Fungal
Microbial
