Secondary processing covers either the direct or indirect (processing of intermediates from primary processing) valorisation of biowaste into a final product. While some technologies are used exclusively for the purpose of secondary processing, others (such as the separation processes and technologies) can be utilised in both primary and secondary processing which places them into hybrid processing.
