Composting of fine fraction after mechanical-biological treatment of municipal solid waste

One of most common types municipal solid waste treatment is mechanical-biological (MBT), which in practice has many variations depending on the method conducting technological process and it possible to get different output fractions. In this paper analysed generated after MBT with biodrying, where mechanical undergoes then RDF (recovery derived fuel) separated. Fine fraction remains a high content organic matter that without additional processing cannot be disposed landfill. The aim research was determine possibility fine composting conditions – open, open covered area, indoors. each area are formed three compost piles: 100% (KH1, KH4, KH7), 70% 30% wood chips (KH2, KH5, KH8), 50% (KH3, KH6, KH9). Moisture content, temperature dissolved carbon (DOC) were monitored. Results show 13 weeks samples KH1, KH7 (100% fractions) did not achieve DOC value less than 3 000 mg/l. effective terms reducing achieved KH3, KH9. Based results obtained, can concluded by adding ratio 50:50, fastest reduction samples.
