Abstract

Nepravilno gospodarenje otpadom dovodi do štetnih posljedica u okolišu uz rizik za javno zdravlje. Poznavanje svojstava otpada ključno je za iskorištavanje njegovog potencijala, čija oporaba postaje ozbiljan izazov diljem svijeta. Osim što stvara potencijalne ekološke probleme, otpad ne samo da predstavlja gubitke iz proizvodnog procesa vrijednih sirovina i energije, već zahtijeva i značajna ulaganja u kontrolu onečišćenja. U ovom radu provedena je karakterizacija organske frakcije miješanog komunalnog otpada simulacijom procjedne vode u laboratorijskim uvjetima. Rezultati pokazuju da udio biorazgradive organske frakcije u miješanom komunalnom otpadu je veći od 61,5 % uz visoku prosječnu vrijednost omjera BPK5/KPK od 0,80±0,05 što ukazuje na značajan potencijal za biološku valorizaciju ispitivanog realnog uzorka.

Abstract (english)

Improper waste management leads to harmful environmental consequences and poses risks to public health. Understanding the properties of waste is crucial for harnessing its potential, and its recovery is becoming a serious challenge worldwide. Besides creating potential ecological problems, waste not only represents losses of valuable raw materials and energy from the production process, but also requires significant investments in pollution control.
In this study, the characterization of the organic fraction of mixed municipal waste was conducted by simulating leachate in laboratory conditions. The results show that the biodegradable organic fraction in mixed municipal waste is over 61.5%, with a high average BOD5/COD ratio of 0.80±0.05, indicating significant potential for biological valorization of the tested real sample.
