Abstract

Današnje društvo je iz dana u dan sve svjesnije problema koje uzrokuje odbačena plastika u okolišu. Većina plastike u okolišu se neće u potpunosti razgraditi, nego se raspada na sve manje i manje dijelove tvoreći mikroplastiku. Iako je znanje o učinku mikroplastike na okoliš i ljude i dalje ograničeno, iz dana u dan znanstvenici dolaze do novih saznanja i postupaka za njeno uklanjanje. U ovom radu dan je pregled postupaka za uklanjanje mikroplastike iz okoliša. Neki procesi, poput biorazgradnje i fotorazgradnje, rezultiraju djelomičnim smanjenjem volumena i mase mikroplastike, dok napredni oksidacijski procesi rezultiraju potpunom razgradnjom mikroplastike. Nadalje, sve više se ispituju membranski procesi kojima se postiže visoki stupanj uklanjanja mikroplastike iz voda, ali njihov nedostatak je cijena i često mijenjanje membrana. Novija istraživanja bave se kombinacijom navedenih procesa, upravo kako bi uklanjanje mikroplastike iz okoliša bilo ekonomski isplativo i ekološki prihvatljivo.

Abstract (english)

Today's society is increasingly aware of the problems caused by discarded plastic in the environment. Most of the plastic in the environment does not fully degrade, but breaks down into smaller and smaller pieces, creating microplastics. Although knowledge about the effects of microplastics on the environment and humans is still limited, scientists are developing new knowledge and methods to eliminate them. This paper provides an overview of methods to remove microplastics from the environment. Some processes, such as biodegradation and photochemical degradation, result in a partial reduction in the volume and mass of microplastics, while advanced oxidation methods result in complete degradation of microplastics. In addition, membrane processes that achieve high levels of microplastic removal from water are increasingly being tested, but they lack pricing and frequent membrane replacement. Recent research is looking at a combination of the above processes to make the removal of microplastics from the environment economically viable and environmentally acceptable.
