At its plant, which is according to the By-Products Regulation, Biovakka produces environmentally friendly recycled nutrients. Such nutrients are well-suited for field cropping and improve the characteristics of the soil by returning to it humus and carbon. At the same time, they reduce soil nutrient washout. At Biovakka, by-products are treated both biologically and through hygienisation. The end product is suitable for field use as such. Biovakka's recycled nutrients are produced as part of the biogas process. Thanks to this, they have high-quality hygienic properties and their nutrient values are good. In addition, they lack the typical smell of livestock sludge. The nutrients produced in the biogas process have fared extremely well in different comparisons of nutrient effectiveness.
