Across the grain-dominated farmlands of northern Europe, a quiet rethinking is underway — one that asks whether the humble grass and clover, long valued as soil restorers, might also become the raw material for a more self-sufficient and ecologically grounded food system. Researchers at Chalmers University of Technology are developing green biorefineries capable of transforming freshly harvested biomass into protein feed, biogas, and carbon-capturing materials, offering a potential answer to Europe's dependence on imported soy and the environmental costs that dependence carries. The science is
