Popis: | Plastics are highly advanced materials that have a vast array of applications and are produced globally in an approximate amount of 350 to 400 million tons every year. Nevertheless, there are serious concerns about plastic waste and pollution as a result of the misuse and lack of control of their use in industries, including packaging, transportation, manufacturing, and agriculture. Approximately 1,000 years are required for plastic bags to decompose efficiently. Additionally, CO2 and dioxins are released into the atmosphere by burning plastics, and they contribute to global warming. The Earth’s environment is overwhelmed with waste, mostly from poor recycling practices and low circular usage, resulting in millions of tons of waste generated annually. To combat this, new technologies for recycling post-consumer plastics are desperately needed to decrease plastic waste and improve the environment, while also finding ways to utilise these materials. Due to the inadequate disposal methods currently available for plastic waste, there has been increased interest in the use of microorganisms and enzymes designed for the biodegradation of non-degradable synthetic polymers via biocatalytic depolymerisation indicating that plastics treatment and recycling can be more efficient and sustainable. Plastika je daleko najnapredniji materijal kad je riječ o primjeni i svojstvima, a procjenjuje se da se svake godine globalno proizvede 350 do 400 milijuna tona. Ona je postala ozbiljan problem s obzirom na odlaganje plastičnog otpada i onečišćenje, zbog njezine nekontrolirane upotrebe u različite svrhe tijekom posljednjih desetljeća, kao što su pakiranje, transport, industrija i poljoprivreda. Za učinkovitu razgradnju plastičnih vrećica potrebno je otprilike 1000 godina. Osim toga, izgaranjem plastike u atmosferu se ispuštaju CO2 i dioksini koji doprinose globalnom zatopljenju. Zemaljski kopneni ili morski okoliš akumulira milijune tona otpada svake godine zbog lošeg recikliranja i niske kružne upotrebe. Inovativne tehnologije za recikliranje otpadne plastike prijeko su potrebne za smanjenje plastičnog otpada i postizanje ciljeva kvalitete okoliša uz valorizaciju potrošne plastike. Zbog trenutačno neadekvatnih metoda zbrinjavanja plastičnog otpada povećan je fokus na upotrebu mikroorganizama i enzima dizajniranih za biorazgradnju nerazgradivih sintetičkih polimera putem biokatalitičke depolimerizacije, što ukazuje na to da obrada plastike i recikliranje mogu biti učinkovitiji i održivi. |
