The paper presents the results of an analysis of the changes of the mass and amounts of organic substances and combustible elements in a biodegradation process. The prepared sample of organic waste constituted the material used for the tests. The composting process was being carried out for 9 weeks in field conditions. The samples for analyses were collected every 7 days. The content of a biodegradable fraction was determined according to the procedure described in the standard of PN - EN 15169: 2007 "Characterization of waste – Determination of loss on ignition in waste, sludge and sediments". Reduction of the mass of the organic waste during the composting process amounted to 35%. A significant content of organic fraction (about 60 – 70% after 9 weeks) remains in the composted waste; and the content of combustible elements is reduced (by about 30%.)
