 Agro-industrial waste is a great resource for producing a range of useful products such as biogas, biofuel, mushrooms and tempeh. This waste can be used instead of traditional sources of raw materials, reducing costs and environmental impact. Additionally, it can be used to produce enzymes, vitamins, antioxidants, animal feed, antibiotics and other chemicals through solid state fermentation, SSF, processes. Various types of microorganisms are used to create these products, which can then be sold or used in industrial applications.
