Dairy farmer Aleid Blitterswijk has built a CO2-neutral hay shed, making him the first in the Netherlands to use this technique. The shed uses solar heat to dry hay and a modern feeding method that includes fresh grass and hay, leading to healthier cows and milk. This milk is now being used to produce a new cheese variety, 'Uut Hooi', and there are plans to also produce ice cream, yogurt, butter, and carton milk. Blitterswijk hopes this will inspire other farmers to adopt sustainable production methods.
