AAK AB will invest SEK500m to install biomass boilers at its production plant in Aarhus, Denmark – an initiative that is expected to reduce the plant’s CO2 emissions by approximately 90%. The installation will also generate substantial savings as fossil fuel will be replaced by shea meal, a by-product from the plant’s shea oil extraction process. The project is expected to be completed by the end of 2023.
The plant in Aarhus has run a small biomass boiler as a pilot over the past five years, in an effort to make its operations more sustainable. As a result of the positive experiences from the pilot, and to further reduce the plant’s environmental impact, two new 18 MW boilers will be installed. Combined, the three boilers are expected to cut CO2 emissions by more than 45,000 tons per year, leading to a 16% reduction in the group’s total scope 1 emissions. In addition, with the boilers running on shea meal, the need for fossil fuel will virtually be eliminated. This is expected to generate yearly savings of up to SEK100m.
“AAK is fully committed to accelerate its reduction of greenhouse gas emissions, and this initiative will definitely result in true progress. Not least will it strongly contribute to delivering on the science-based targets which we are in the process of setting,” said Johan Westman, president and CEO of AAK Group. “We work hard, together with our suppliers, to ensure a sustainable supply chain when sourcing our various raw materials. This investment shows we are equally committed to limiting the environmental impact of our own operations.”
Beyond a CO2 reduction and savings, the use of shea meal to fuel the boilers will generate ash, which in turn can be utilised for fertilising purposes. In essence, all parts of the shea kernels will be used.
AAK’s production plant in Aarhus specialises in the crushing, refining, and fractionation of shea, a unique raw material from West Africa that AAK has been sourcing for more than 60 years. At the plant, AAK produces a large number of products, among them shea stearin – a major component in CBE (cocoa butter equivalents), frequently used in chocolate and confectionery products. AAK also supplies shea-based emollients for cosmetics and personal care products.
