The incubation of polymer samples took place for a period up to 24 months. The characteristic parameters of compost: temperature, pH, moisture content and activity of dehydrogenases were monitored and their influence on degradation of polyurethanes was discussed. The proper compoststability of polyurethanes was investigated by changes of weight, tensile strength and morphology of polyurethane samples after incubation in environment. The degradation study revealed that the degree of degradation of polyurethanes in the natural environment, like compost, is dependent on their chemical and structural composition.
