UZWIL, SWITZERLAND — Bühler Group and Vyncke have formed a strategic partnership to offer integrated solutions with which biomass side stream products are transformed into clean process energy while reducing the customers’ carbon footprint.

The dependency on fossil fuels — and with this, CO₂ emissions — can decrease from 20% to 100%, depending on the raw material and side stream products. This means that in some cases, food plants can become fully carbon neutral. The first focus of the partnership is the segments of cocoa, oat, and malt processing.

“This partnership is a key element in our strategy to massively reduce CO₂ in the value chains of our customers,” said Johannes Wick, chief executive officer of Bühler Grains & Food.

“Many industries rely on our solutions to reduce their fossil fuel consumption,” said Peter Vyncke, owner of Vyncke. “With Bühler, we now aim to also become the standard to reduce the CO₂ footprint of the food industry. Together, Bühler and Vyncke can now offer integrated and optimized solutions where economic and ecological benefits go hand in hand.”

 With new equipment, digital services and retrofit offerings, Bühler already made strong progress in making its solutions more energy efficient.

“By adding Vyncke's energy recovery processes to our portfolio, we can offer our customers low- to zero-carbon food solutions,” Wick said.

Belgian technology supplier Vyncke specializes in energy production from a wide range of biomass byproducts, including industrial or municipal wastes. The range of biomass-based fuels available for energy production is broad; from agricultural and wood residues to sludges from industrial processes, recycled wood, and specially grown energy crops.

Vyncke designs and builds green and clean energy systems that combust biomass and waste to produce thermal process energy from 1-100 megawatt hours (Mwh) and electrical energy from 0.5-15 megawatt electrical (Mwe).

 With their cooperation, Bühler Group and Vyncke are developing solutions for more sustainable food production — with holistic process chains in which energy recovery is integrated so that external energy consumption and energy costs can be reduced. This not only contributes to greater sustainability, but also opens competitive advantages for food producers through greater energy efficiency.

“Today, we are far from exploiting the full potential of recovering energy from side stream products,” Vyncke said. “Our goal is to reduce the energy consumption of a food plant by up to 70%. The beauty of our solutions is that sustainability and economic criteria go hand in hand. Today, we are already enabling our customers to reduce emissions by 2.5 million tons of CO₂ annually. By partnering with Bühler, we can further improve and scale these solutions in an integrated approach to create a much larger positive impact.”

One particularly important joint project will be the expansion of a malt production plant for Bühler's longtime business partner, Malteria Oriental SA in Montevideo, Uruguay. Malteria Oriental SA belongs to the Grupo Petrópolis, one of Brazil’s largest beer producers. The company’s brewing business requires more malt, as beer consumption in South America has grown steadily in recent years.

 In the project, Vyncke will be responsible for recovering thermal energy from biomass, which is a byproduct of malt production. Through an on-site energy audit, Vyncke developed a set-up to reduce the size of the energy system by 30%, creating savings in the total investment as well as the operational costs. Vyncke will build a turnkey 20-megawatt superheated water boiler with dual combustion systems, which will burn internal barley husks and plant rejects, completed by externally sourced wood chips. This will save 35,000 tons of CO₂ emissions each year compared to standard operational practices in Uruguay.

The new malt house is designed for a batch size of 260 tons of barley and has an annual capacity of 77,000 tons of malt. Commissioning and production are scheduled for March 2022.

“By working closely together, we aim to execute projects with less coordination effort for our customer,” Wick said. “Our joint innovative strength will drive us into the future and our customers will have ever better and more efficient solutions at their disposal.”

Both Vyncke and Bühler have set the goal of reducing energy consumption in all new food plants by at least 50% by 2025. Together, both partners want to create the possibility of making malting plants CO₂ neutral. The project in Uruguay is just the beginning. In the future, both partners intend to coordinate their solutions technologically in a targeted manner.
