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.
