10 years ago, the Netherlands sugar industry turned to Krieg & Fischer Ingenieure GmbH. The Suiker Unie faced different challenges in 2011: On the one hand, the increasing taxes for CO2 emissions and, on the other hand, the high energy consumption for drying the dried beet pulp.

Independence - that's where we need to be. Independence from taxes, independence from natural gas. But also, independence from seasons. Our engineers were challenged to design a biogas plant capable of safe, economical and ecological operation 24/7, regardless of the seasonal processing of sugar beet.

Six months later, we designed a solution tailored to the needs of the sugar industry. In short, it ensures all-season sugar beet fermentation, which converts sugar beet into energy. Surplus CNG is fed into the natural gas grid, while digestate is used as fertilizer in agriculture.
