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?
