Less food waste generated by food stores and food services 

In 2021, 143,254 tonnes of food waste was generated. The total amount was 0.2% smaller than in 2020. SURS estimates that the share of the edible part of food waste decreased by 2 percentage points from 40% in 2020 to 38% in 2021.

Most food waste was generated by households (53%). In food services, 28% of total food waste was generated, in food stores 10%, and the least (9%) in food production. 

Compared to the year before, less food waste was generated in food stores (by 5%) and in food services (by 6%). The amounts went up in food production (by 24%) and in households (by 1%).

More food waste treated in composting plants 

The largest share of food waste (almost 43%) was anaerobically treated in biogas plants. This is followed by aerobic treatment of food waste in composting plants with 34%. 19% of food waste was biologically stabilised before being disposed in plants for the mechanical and biological treatment of municipal waste (MBO). The rest of food waste (4%) was processed with other methods, such as incineration, oil refining and other biological recovery processes. 

Compared to 2020, the amount of composted food waste increased by 7%, while the amount of food waste processed in biogas plants decreased by almost 9% due to some restoration in biogas plants. The amount of food waste biologically stabilised before disposal went down by almost 1%.
