Abstract

Tema ovog diplomskog rada je tehno-ekonomska analiza potencijalnog pirolitičkog
postrojenja koje bi se izgradilo u sklopu realnog poslovnog subjekta. Predmetno poduzeće
bavi se gospodarenjem neopasnim otpadom. Uspješnost njihove obrade kreće se od 70% za
plastiku pa do 90% i više za papir, karton, metalni otpad i biorazgradivi otpad. Nakon procesa
recikliranja poslovnom subjektu godišnje ostane 985 tona ostatnog otpada, a udio ostatnog
otpada pirolitički bi se obrađivao. Od ukupno 985 tona, plastika koja bi se obrađivala iznosi
401,8 tona. Obradivu plastiku čine PS, PP, HDPE, LDPE i ostalo (7). PVC i PET nije
poželjno obrađivati zbog loših svojstava u smislu procesa pirolize te ih je potrebno zbrinuti s
ostalim otpadnim tokovima. Projekcijom količine nastalog otpada sukladno zahtjevima EU
može se uvidjeti da će doći do povećanja količina odvojenog otpada. Sukladno tim
zahtjevima, kapacitet potencijalnog postrojenja povišen je na 1 071,6 tona. Ostali parametri,
poput prinosa ulja, ulazne naknade i raznih troškova, određeni su pregledom literature. Svi
dostupni parametri su zabilježeni i osrednjeni. Tako osrednjenim parametrima i navedenim
kapacitetom provedena je ekonomska analiza i analiza osjetljivosti kojima je utvrđena
neisplativost projekta. U ostatku rada navedeni su potrebni koraci za projektiranje ekonomski
isplativih postrojenja, njihova usporedba te zaključak. Svi proračuni izvršeni su u programu
Excel.

Abstract (english)

Theme of this thesis is the techno-economic analysis of a potential pyrolysis plant which
would be built by a waste management company. The company’s primary objective is waste
recycling. Their rate of recycling ranges from 70% for plastics to 90% and more for paper,
cardboard, metal and biodegradable waste. After waste goes through recycling process, the
company is left with 985 tonnes of non-recyclable waste on a yearly basis. Percentage of said
non-recyclable waste would be used in pyrolysis plant for production of pyrolysis oil. Out of
985 tonnes of non-recyclable waste, 401.8 tonnes would be used in pyrolysis process. Those
401.8 consist of PS, PP, HDPE, LDPE and other (7) types of plastic. PVC and PET should
not be used in pyrolysis process due to their bad characteristics. Instead, they should be
adequately disposed along with other waste outputs. In accordance to EU’s municipal solid
waste recycling requirements, it was projected that the amount of recycled waste will be
increased. Thus, the capacity of a potential pyrolysis plant was increased to 1 071.6 tonnes.
Other parameters, like oil yield, gate fee and various expenses, were determined by studying
the literature. Found parameters were marked down and averaged. With those parameters and
said capacity, economic analysis was carried out. It was determined that the plant capacity
does not suffice in order to make the project feasible. In the rest of the thesis, it was shown
what needs to be changed in order to design a profitable plant with a conclusion. All
calculations were done in programme Excel.
