Bühler’s Energy Recovery Centre, built in partnership with Belgian company Vyncke, is fully operational and ready for customer trials.
Officially opened on November 20, the facility provides heating for Bühler offices in Uzwil by using biomass generated at its application and training centres.
Moreover, the Energy Recovery Centre, the world’s only application centre of this kind and size, works as a platform for customers to explore the potential of using side streams through energy recovery, which can lead to the reduction of their carbon footprint, waste and energy costs.
The Energy Recovery Center (ERC) combines Bühler’s expertise on biomass fine grinding and preparation with Vyncke’s combustion knowledge and latest technology (optimising the energy yield), resulting in an integrated and cost-efficient energy solution.
Vyncke installed its red-walled boiler at Bühler’s site. This is also the first time that the technology of multi-staged pyro gasification turbix combustion for agricultural fuels is used.
The fuel injection system combined with the injection of the primary and secondary combustion air will lead to better combustion, and therefore, lower emissions, said the company.
The plant has two purposes. The first objective is the management and generation of sustainable energy. The ERC will be fed by various side streams generated by the application and training centres in Uzwil. This fully integrated solution will go on to process the fuel, generate hot water and send this energy back to heat the buildings.
The second function is to test the biomass side streams from the processes of Bühler’s global customer base. The side streams that will be tested in the centre cover a broad range of materials including wheat bran, rice husks and cocoa shells.
The by-products will be combusted either individually or in a mixture with a test and learn approach.
The ERC is scientifically supported by the Swiss Federal Laboratories for Materials Testing and Research (EMPA) to evaluate research and development (R&D) results and further applications of boiler ash (i.e., as fertiliser or building material production).
“By adding Vyncke’s energy recovery processes to our portfolio, we can offer our customers new processes towards a more sustainable production,” said Johannes Wick, CEO of Grains & Food at Bühler.
“With the Energy Recovery Center and Bühler’s application and training centres, our customers have the ideal platform and expertise to make sure their investments for the future are sound and proven.”
Peter Vyncke, owner of Vyncke, said: “Many industries rely on our solutions to reduce their fossil fuel consumption. With Bühler, we now aim to also become the standard to reduce the CO2e footprint of the food industry.”
