A micromethanization unit has been established at a vegetable farm in Holtzwihr, Haut-Rhin, aiming to convert vegetable waste and brewery byproducts into biogas for heating and electricity. Developed by the Strasbourg startup Arkeale, this compact unit is designed for small-scale operations and targets 40% energy autonomy for electricity and 100% for hot water. The system, costing approximately €400,000, is expected to be profitable within 6 to 10 years, with plans for three more units in the region by 2027.
