A core part of AB Mauri’s GHG emissions reduction strategy is investing in energy efficiency, particularly at its yeast production plants. Yeast production requires both electricity and heat, primarily to create steam, which is used throughout the process to keep equipment sterile. Recovering heat from this production process to use in another is a key way energy use can be reduced. At its site in Bandirma, Turkey, a state-of-the-art two-stage economiser was added to an existing steam boiler in 2024. The economiser now takes flue gas waste heat from the boiler, which was previously lost, recycling it to heat cold water coming into the boiler. The project reduced the site’s emissions by approximately 200 tCO2e in 2024. Another significant investment in improved evaporator technology has enhanced overall site efficiency by improving co-products processing. This contributes to an annual reduction in emissions of over 1,300 tCO2e.
