Abstract

Građevinska industrija dugi niz godina posluje po principu linearne ekonomije koja na svom kraju ostavlja otpad kao zadnji produkt. Značajan porast cijena, povečana nestabilnost globalnih robnih trzišta i štetni nusprodukti su doveli do preispitivanja takve ekonomije, u pogledu potrošnje sirovina i energije. Cirkularna ekonomija predstavlja novi ekonomski model koji nastoji odvojiti ekonomski rast i razvoj od potrošnje ograničenih resursa. U građevinskom sektoru, prijelaz s linearne na cirkularnu ekonomiju zahtijeva koncentraciju na sistematičnom razmišljanju, kako bi se shvatio cjelokupni životni vijek građevine i građevinski lanac vrijednosti. Cirkularna ekonomija je zasnovana na kruženju materijala u procesu korištenja i ne stvaranju novog, nepotrebnog otpada, na tzv. 4R principu. Taj princip objedinjuje četiri aktivnosti kojima se korištenim materijalima „vračaju" njihova svojstva te ostaju u uporabi. Sam naziv dolazi od engleskih riječi – smanjivanje, ponovne uporabe, prerade i recikliranja (reduce, reuse, remake, recycle). Cilj ovog rada je ustanoviti u kojoj mjeri su zaposleni u građevinskim poduzečima upoznati s konceptom cirkularne ekonomije i njegovom primjenom. U tu svrhu, provedeno je istraživanje putem anketnog upitnika koje je pokazalo kako su ispitanici još uvijek nedovoljno upoznati s pojmom CE, ali je istaknulo koji indikatori cirkularnosti u građevinarstvu mogu biti važni za definiranje budučih okvira i poslovnih strategija građevinskih poduzeča.

Abstract (english)

For many years, the construction industry has operated on the principle of a linear economy, with waste as the final product. Significant price increases, increased volatility in global commodity markets, and hazardous by-products have prompted a re-examination of such an economy in terms of raw material and energy consumption. The circular economy is a new economic model that seeks to separate economic growth and development from the use of limited resources. The transition from a linear to a circular economy in the construction sector necessitates a focus on systematic thinking in order to comprehend the entire life cycle of a building and the building value chain. Circular economy is based on the circulation of materials in the process of use and not the creation of new, unnecessary waste, the so-called 4R principle (reduce, reuse, remake, recycle). The purpose of this work is to determine how familiar employees in construction companies are with the concept of circular economy and its application. To that end, an on-line survey was conducted, which revealed that respondents are still unfamiliar with the term of circular economy, but also showed which circularity indicators in construction may be important for defining future frameworks and business strategies of construction firms.
