Last week, Vuna and VaLoo to present the complete closed-loop system of the renovated Wilmatt farmhouse in Winznau SO to an interested audience.
💦 Wilmatt prepares its own drinking water from rainwater and spring water,
🌿 Produces valuable compost and saves massive amounts of water thanks to the dry toilets in both apartments,
🪱 and treats the grey water in worm and plant filters so that it feeds the small stream next to the property.
