Abstract

S porastom svjetske populacije dolazi do porasta količine nastalog otpada. Stoga se javlja globalni problem zbrinjavanja otpada. Uz zakone o izdvajanju materijala za recikliranje iz otpada, mnogobrojna reciklažna dvorišta i razne usluge prikupljanja otpada i dalje postoji problem sa odlaganjem i zbrinjavanjem miješanog komunalnog otpada. Jedno od mogućih rješenja je proizvodnja goriva iz otpada, GIO. Prema podacima iz 2018. godine, u svijetu postoji oko 1180 postrojenja za energetsku oporabu otpada. Gorivo iz otpada obuhvaća sav otpad koji se koristi u energetske svrhe, no bez standardizacije i klasifikacije takvo gorivo ne predstavlja pouzdan izvor energije. Stoga je razvijen sustav standarada koji precizno definiraju goriva iz otpada. Tako definirana goriva nazivaju se SRF (engl. Solid Recovered Fuel). Standardizacija zahtjeva poznavanje donje toplinske vrijednosti goriva ( Hd ), te udio opasnih elemenata poput klora i žive. Na temelju tih vrijednosti izrađene su klase goriva. Uspostavom ovakve standardizacije omogućen je razvoj novih tehnologija energetske oporabe otpada, što dovodi do smanjenja volumena otpada na odlagalištima i smanjenju utjecaja na okoliš.

Abstract (english)

As the global population increases, the amount of generated waste also rises, leading to a significant global waste management problem. Despite regulations on the separation of recyclable materials, numerous recycling facilities, and various waste collection services,
the issue of disposing of mixed municipal waste persists. One potential solution is the production of Refuse Derived Fuel (RDF). According to 2018 data, there are approximately 1,180 waste-to-energy facilities worldwide. Refuse Derived Fuel encompasses all waste used for energy purposes; however, without proper standardization and classification, such fuel does not provide a reliable energy source. Consequently, a system of standards has been developed to precisely define waste-derived fuels. These standardized fuels are known as Solid Recovered Fuel (SRF). The standardization process requires knowledge of the lower heating value (LHV) of the fuel, as well as the concentration of hazardous elements such as chlorine and mercury. Based on these parameters, fuel classes have been established.
The implementation of such standardization has enabled the development of new waste-to-energy technologies, leading to a reduction in the volume of waste disposed of in landfills and a decrease in environmental impact.
