The aim of the study was to evaluate the inactivation of Ascaris suum eggs during composting waste from municipal green areas with the addition of sewage sludge from Kneer container technology. Carriers with parasite eggs were placed in the top, medium and bottom layers of the composted biomass. Analyses showed distinct differences in egg inactivation in particular biomass layers. Ascaris suum eggs survived longest at the bottom - from 3 days in the summer cycle to 161 days in the spring cycle. The egg’s elimination rate in the summer cycle was remarkably higher than in the spring. No eggs able to develop further were detected at all the tested layers of the biomass after 4 days, while in spring the survival rate based on a calculation regression lines ranged from 20 to 161 days.
