Combined strategy in the management of industrial side streams - production of residual soil improvement in the mitigation of environmental burden

Microbial multitudes maintain the cycles of nutritive elements in natural ecosystems. We have piloted organic residues of various processes including the food and forest industries as well as municipal waste management. This approach opens up avenues for combining economic and ecological objectives together, which has been evidenced in Finland e.g., in Tampere, Hiedanranta project in 2017 – 2022 with sedimented lake bottom deposits of cellulosic fibers, or in case of combined bioprocessing of meat industry wastes into biogas and organic fertilizers in Kitee (2020 – 2022). The chemical products in the processes include organic acids and sugar alcohols, such as mannitol, whose production was accomplished at record levels using patented technologies developed by Finnoflag Oy. The resulting organic fractions were processed into valuable biofertilizers.
