Energy is a large input cost in the malting process and for this reason maltsters were early to adopt technologies which would create greater efficiencies in kilning. There are many examples and include such improvements as heat recovery from exhaust air, variable speed fans, and replacement of boilers with more efficient models. The introduction of Combined Heat and Power was a big investment at some sites from the 1980s onwards and continues to be an efficient system to operate.
Malting companies have Climate Change Agreements (CCA) which are managed by the MAGB and demonstrate a commitment to improved energy use efficiency and the associated reduction in Greenhouse Gas Emissions in all their operations. Further information about the CCA scheme can be found here.
The next big step for members is to switch to renewable fuels, several companies have already invested in biomass heating plants, an example being that at Muntons – Brewing Green. Other projects across the sector include solar, wind Simpsons Malt Limited to cut Tweed Valley Maltings carbon emissions by 80% through Energy Centre development – Simpsons Malt, and hydrogen UK Malting Moves Towards a Greener Future: Protium and Bairds Malt Announce Initial Results of Partnership to Decarbonise UK Malting – Protium.
