Abstract

Otpad je svaka tvar ili predmet koji posjednik odbacuje, namjerava ili mora odbaciti. Postoje dva osnovna načina podjele otpada i to po mjestu nastanka i po svojstvima otpada. Prema mjestu nastanka otpad se dijeli na komunalni i industrijski otpad. Prema svojstvima otpad se razvrstava na: opasni, neopasni i inertni otpad. Brz razvoj industrije i visok tehnološki napredak glavni su izvori povećanja otpadnih materijala. Neadekvatno gospodarenje otpadom dovelo je do onečišćenja okoliša te do ozbiljnog utjecaja na javno zdravlje pa je potrebna uspostava efikasnog sustava zbrinjavanja. Kako se količina otpada svakodnevno povećava, važno je poboljšati postojeće i razvijati nove mehanizme za njegovo zbrinjavanje. Sustav mehaničko biološke obrade – MBO (eng. MBT) je postrojenje za obradu otpada u kojem se kombiniraju dva procesa: mehanička (M) i biološka (B) obrada (O) otpada. MBO postrojenja dizajnirana su za obradu miješanog komunalnog otpada, a također i industrijskog otpada. U okviru ovog diplomskog rada predstavljen je utjecaj sezonskih varijacija na prosječni sastav ostatnog komunalnog otpada nakon obrade u Centru za gospodarenje otpadom Marišćina. Cilj istraživanja bio je da se utvrdi postoje li bitne razlike u osnovnim geotehničkim svojstvima ostatnog otpada iz zimskog i ljetnog perioda. Provedena ispitivanja pokazala su da uzorak iz ljetnog perioda sadrži 7,6% veći udio organske tvari iz čega proizlazi da ljetni uzorak ima veći potencijal za proizvodnju bioplina. Također su utvrđena odstupanja u postotnim udjelima pojedinih komponenti otpada prema obliku zrna, a što bi moglo imati utjecaja na iznos posmične čvrstoće.

Abstract (english)

Waste is any substance or object that the holder discards, intends to discard or must discard. There are two basic ways of separating waste, according to the place of origin and waste properties. According to the place of origin, waste is divided into municipal and industrial waste. According to the properties, waste is classified into: hazardous, non-hazardous and inert waste. Rapid industrial development and high technological progress are the main sources of an increase in waste materials. Improper waste management has led to environmental pollution and has had a serious impact on public health, so it is necessary to establish an efficient disposal system. As the amount of waste increases daily, it is important to improve the existing disposal mechanisms and to develop new ones. Mechanical biological treatment system – MBT is a waste treatment plant that combines two processes: mechanical (M) and biological (B) treatment (T) of waste. MBT plants are designed for the treatment of mixed municipal waste and industrial waste. The graduate thesis presents the influence of seasonal variations on average composition of municipal solid waste after treatment at the Marišćina Waste Management Centre. The purpose of the research was to determine whether there are significant differences in the basic geotechnical properties of residual waste from a winter and summer period. The conducted tests showed that the sample from a summer period contained a 7,6% higher share of organic matter, which means that the summer sample has a higher potential for biogas production.
Deviations in the percentages of individual waste components according to the grain shape were also determined, which could have an impact on the amount of shear strength.
