.Energy efficiency equipment at AB Mauri's factory in Casteggio, ItalyAB Mauri's yeast plant in Casteggio, Italy, is decarbonising its operations through the implementation of various technologies and initiatives. The focus has primarily been on improving energy efficiency through advanced fermentation aeration technology, high-efficiency natural gas boilers, steam distribution optimisation and new heat recovery systems. In 2024, the plant introduced a new boiler that uses renewable biogas, generated as a by-product of its anaerobic digestion water treatment process, to supply low-carbon heat. These efforts have reduced carbon intensity (tCO2e/tonne of product) by 9% since 2018, excluding changes in grid electricity carbon intensity. Further reductions are expected in 2025 as additional energy efficiency measures, including rooftop solar panels, are implemented, allowing for the decommissioning of a natural gas turbine
