Similar to conventional refineries, biorefineries can provide multiple chemicals by fractioning an initial raw material (biomass) into multiple intermediates (carbohydrates, proteins, triglycerides) that can be further converted into value-added products.
Ngokufana nokucwenga okuvamile, ama-biorefineries anganikeza amakhemikhali amaningi ngokuhlukanisa izinto zokuqala ezingavuthiwe (i-biomass) zibe ama-intermediates amaningi (ama-carbohydrate, amaprotheni, ama-triglycerides) angaguqulwa futhi abe yimikhiqizo enezelwe inani.
