Abstract

Problematika rasta ukupnih količina otpada jedan je on najvažnijih ekoloških problema današnjice. Cjelovit sustav gospodarenja otpadom daje nam jasne naputke i mjere u svrhu rješavanja ovog problema. Jedna od najistaknutijih mjera jest primjena procesa obrade otpada kako bi se smanjila količina otpada na odlagalištima te dobili vrijedni resursi. U ovom radu provedena je procjena biorazgradivosti organske frakcije iz miješanog komunalnog otpada. Rezultati pokazuju da je udio biorazgradive frakcije u miješanom komunalnom otpadu u prosjeku visok i iznosi 73,62±1,50 %. Visoka prosječna vrijednost omjera BPK5/KPK od 0,78±0,04 ukazuje na mogućnost biološke obrade.

Abstract (english)

The problem of increase in total waste is one of the most important environmental problems of today. A comprehensive waste management system gives us clear instructions and measures to tackle this problem. One of the most important measures is the application of the waste treatment process to reduce the amount of waste in landfills and recover valuable resources. In this work, an evaluation of the biodegradability of the organic fraction of mixed municipal waste was carried out. The results show that the content of biodegradable fraction in mixed municipal waste is high on average and is 73.62±1.50 %. A high average value of BOD5/COD ratio of 0.78±0.04 indicates the possibility of biological treatment.
