Abstract

Pružanje dobara i usluga našem društvu doprinosi širokom rasponu utjecaja na okoliš. Stvaranje otpada, emisije stakleničkih plinova i potrošnja resursa događaju se u mnogim fazama životnog ciklusa proizvoda i procesa, od eksploatacija sirovina, dobivanja energije, proizvodnje, recikliranja, pa sve do konačnog odlaganja i zbrinjavanja. Sve to pridonosi stvaranju negativnih utjecaja na okoliš kao što su oštećenje stratosferskog ozona, stvaranje fotooksidata (smog), pojave eutrofikacije, zakiseljavanja tla, toksikološki stres na zdravlje ljudi i ekosustave, te iscrpljivanje resursa. Za postizanje UN-ovog cilja održivog razvoja postoji potreba za sveobuhvatnim i robusnim alatom koji pomaže pri donošenju odluka u identifikaciji rješenja koja su najbolja potpora održivom razvoju. Odluke moraju imati sistemsku perspektivu, razmotriti životni ciklus i sve relevantne utjecaje koje rješenja uzrokuju. Procjena životnog ciklusa (LCA) je alat koji ima sve ove karakteristike. LCA je alat za procjenu utjecaja pojedinih procesa i proizvoda na okoliš i resurse koji se koriste tijekom životnog ciklusa proizvoda. U ovom radu cilj je upoznati se sa osnovama LCA-a, razvojem alata kroz povijest, te njegovom metodologijom, te kroz primjer korištenja LCA metode u električnoj automobilskoj industriji razviti slika na koji način LCA proučava pojedine procese i proizvode.

Abstract (english)

The provision of goods and services to our society contributes to a wide range of environmental impacts. Waste generation, greenhouse gas emissions and resource consumption occur in many phases of the product and process life cycle, from raw material exploitation, energy production, manufactoring, recycling, to final disposal. All of this contributes to the creation of negative environmental impacts such as climate change, stratospheric ozone depletion, photooxidation, eutrophication, soil acidification, toxicological stress on human health and ecosystems, and resource depletion. To achieve the UN goal of sustainable development, there is a need for a comprehensive and robust tool to assist decision-making in identifying solutions that best support sustainable development. Decisions must have a systemic perspective, consider the life cycle and all relevant impacts that are caused by solutions. Life Cycle Assessment (LCA) is a tool that has all of these characteristics. LCA is a tool for assessing the impact of individual processes and products on the environment and resources used during the product life cycle. In this paper, the aim is to get acquainted with the basics of LCA, the development of tools throughout history, and its methodology, and through the example of using the LCA method in the electrical automotive industry to develop a picture of how LCA studies individual processes and products.
