In a world of growing demand yet finite resources, efficient food production and energy use are an imperative for Bühler’s customers to drive business successfully into the future. 

For Bühler, developing sustainable solutions is not just a fundamental business driver but also a core company principle. All new Bühler solutions will cut 30% of energy consumption and waste by 2020.

Energy-efficient solutions

Higher energy efficiency isn't just sustainable; it also makes economic sense. In the processing industries, energy accounts for up to 10% of total cost. So any saving translates directly into higher margins. In the latest Tubex scale generation, for example, an electromechanical drive reduces operating energy costs by over 90%. And the potential is by no means exhausted. Around 60% of energy consumption in the processing industry is accounted for by process heat. Feed pellets, breakfast cereals, and pasta have a certain moisture content during production but, ultimately, need to have a long storage life. The energy required for the drying processes is commensurately high. Thanks to an innovative heat exchange concept, the Ecothermatic dryer for long goods, for example, requires 40% less thermal energy. The cereal dryers in the EcoDry line are likewise among the most economical of their kind. In 2015, they were singled out for an award in the DGL Focus Test in the “Drying Efficiency and Energy Consumption” category. And they are sustainable in a second sense because they play a significant role in reducing losses after the harvest, too.

Sustainability for animal feed

Increased sustainability is also a top priority for animal feed: In aquaculture, for instance, currently the fastest growing section of the agricultural economy. Fish farms are often criticized because they use fishmeal produced from fish caught in the wild as the basis for their feed. But with the use of Bühler’s extrusion technology, it is easy and efficient to give vegetable raw materials the necessary properties. In the not too-distant future, we’ll be looking into alternative protein sources such as algae or insects as feedstuffs for fish and poultry.
