Brewing - emissions and waste
Biomass burning for thermal energy
Spent grains supplemented with imported wood chips
- to generate economy of scale
- to optimise chemical composition of fuel
Brewers’ grains need to be pressed to at most 50% moisture
Business flexibility: burner may be operated on wood chips alone
- if good price available for animal feed
- dust filter employed to reduce emissions
Still have some ash to send to landfill
Offsets some costs of operating food safety of animal feed systems
- e.g. FEMAS in UK
Consider combined heat and power
Is it possible to use the heat?
Is it possible to sell or use the electricity?
