Businesses in the food and drink sector can generate bio-energy from their bio-degradable residues. On-site Anaerobic Digestion of food processing residues can produce biogas for factory use. If deployed more widely on industrial sites it will reduce reliance on fossil fuels and help cut GHG emissions. One of Britain’s most advanced on-site Anaerobic Digestion (AD) plants, located at First Milk’s Aspatria creamery, is the largest AD plant on a creamery site in Europe.

Uses of heat
High temperature – process steam
 Most valuable form of energy
 Greatest flexibility of use
 Highest demand
 Industrial
Low temperature – process hot water
 Limited applications e.g. process cleaning
 Pre-heating
Very low temperature – domestic water, space heating
 Low energy density of carrier
 Small sized customers?

Conclusion
Opportunity to maximise value for industrial sites
 The upgrading of biogas to biomethane opens up a number of
options for value creation
 The optimum solution is dependent on a variety of factors both
external and site specific
 Potential for site to become increasingly energy self-sufficient
 Industrial sites could become self contained ‘Energy Islands’
