FORBI – Food Residue Biomass is the category of organic waste materials originating from the agri-food supply chain that can be repurposed or valorized for energy production, bio-based materials, soil amendment, animal feed, or other industrial uses. It is considered a sustainable and renewable resource, as it provides an alternative to fossil-based feedstocks while contributing to waste reduction and circular economy goals.

These residues include:

• Crop residues (e.g., stalks, leaves, husks)

• Food processing by-products (e.g., peels, pulp, shells, bones)

• Retail and household food waste (e.g., expired or spoiled food, leftovers)

• Slaughterhouse waste (e.g., blood, fat, organs)

Source: From agriculture, food industry, retail, and households

Composition: Rich in organic matter (carbohydrates, fats, proteins, fibers)

Potential uses:

• Anaerobic digestion (biogas)

• Composting (soil improver)

• Biochar production

• Feedstock for bio-based products
