W HAT DO WE FEED IT ON ? Approach to feedstock's is opportunistic with very few supply contracts. • Pig & Cow Slurry • Whey Permeate and other milk waste • Bakery Waste • Surplus Grass & Maize Silage • Rape Seed Straw

W HAT IS N EXT FOR W YKE ? • More gas production • More solar • Transport – milk tankers? • Can only be as ‘Green’ as current technology allows

W HAT IS N EXT FOR THE A D INDUSTRY ? • More gas from smaller digesters; - Separation of solid and liquid retention times - Improvements of pre-hydrolysis techniques • Increase use of crop residues like straw, chaff etc. • Increase yields from purpose grown crops • Nutrient recovery/separation from digestate
