摘要：<p>The invention relates to a method for treatment of biowaste, like household waste, for reduction of odour and microbial activity and use of treatment agent. A treatment agent is added at least once during a storage period prior to further treatment of the biowaste. An aqueous solution of formate, acetate or propionate, comprising their respective acids and their disalts, is sprayed in amounts of 1-3 weight %, calculated as formate/acetate/propionate equivalents, on the biowaste having a moisture content of 50-75 weight %. Preferably a solution of 15-50 weight % potassium diformate is sprayed on the biowaste each time it is supplied to the bin in amounts of 50-70 ml/kg wet biowaste. The treated biowaste can further be processed to compost by addition of dry biowaste like bark, turf etc. in amounts of 25-75 weight % of the total mixture and said mixture can then be aerated.</p>
