Environmental insights of bioethanol production and phenolic compounds extraction from apple pomace-based biorefinery
Food waste is one of the main challenges of solid waste management throughout the food supply chain. Apples are one of the most widely consumed fruits worldwide, the production of which is accompanied by the generation of pomace as a by-product with valuable nutrients. This research presents the fir...

This research presents the first environmental insights of a multiproduct apple pomace-based biorefinery through a life cycle perspective.
