<onlyinclude>'''Pre-processing''' technologies are utilised in the pre-treatment of biowaste to obtain chemicals and/or materials which will then go into the [[conversion]] followed by an optional [[post-processing]] after which the final product is obtained. While some technologies are used exclusively for the purpose of pre-processing, others such as the separation processes and technologies can be utilised in both pre- and [[post-processing]].</onlyinclude> | <onlyinclude>'''Pre-processing''' technologies are utilised in the pre-treatment of biowaste to obtain chemicals and/or materials which will then go into the [[conversion]] followed by an optional [[post-processing]] after which the final product is obtained.
