Feedstock characteristics

Feedstocks

Feedstocks used by first generation bioethanol production techniques are:

• beet molasses (by-product of sugar production)  
• syrup from sugar production  
• downgraded potatoes  
• downgraded cereals and those from mills  
• whey  
• fruit juices (non-marketed fruits)  
• products from agricultural sectors in difficulty

Characteristics:

• immediate availability  
• little direct competition with the food supply chain  
• utilisation of agricultural surpluses 
• utilisation of co-products for on-site production of energy or animal feed.

Feedstocks used by second generation technologies:

• dedicated agricultural production (miscanthus, grass, etc.)
•  agricultural production wastes (straw, leaves, husks, etc.)
• dedicated forestry production (wood) forestry and wood industry wastes (branches, sawdust, etc.)
• other wood residues, green wastes, part of household waste, etc.
