Austria’s EFKO Launches “Bio Substrat” Project: Turning Potato Waste into Biogas for 600 Homes

Austrian manufacturer EFKO has officially launched its innovative “Bio Substrat” project, marking a significant step forward in industrial sustainability. The initiative focuses on the large-scale conversion of organic production waste—most notably 5,000 cubic meters of steam-peeled potato skins—into renewable biogas. By processing this substantial volume of leftover biomass, EFKO aims to generate enough clean energy to power approximately 600 households. This closed-loop system not only reduces landfill dependency but also cuts greenhouse gas emissions by transforming a high-moisture waste stream into a valuable energy resource.

Beyond energy production, the project exemplifies a zero-waste approach to industrial ecology. The residual digestate left after the biogas fermentation process will be repurposed as a high-quality agricultural fertilizer, returning vital nutrients to the soil. This dual-output strategy ensures that the entire organic input is utilized, creating a circular economy model that benefits both the energy sector and local farming communities. With this pilot, EFKO demonstrates how food processing facilities can evolve into bioenergy hubs, setting a replicable standard for sustainable waste management across Europe.
