“…Numerous papers have been published on the pyrolysis of plastic, where the pyrolysis oil can be used as a fossil fuel substitute or as a crude oil replacement (e.g., Buekens and Huang, 1998;Aguado et al, 2006;Blazsó, 2006). Few cases of largescale applications are documented in the literature and none where marine litter is the feedstock.…”

Marine litter is a significant and growing pollutant in the oceans. In recent years, the number of studies and initiatives trying to assess and tackle the global threat of marine litter has grown exponentially. Most of these studies, when considering macro-litter, focus on floating or stranded litter, whereas there is less information available about marine litter on the seabed. The aim of this article is to give an overview of the current state-of-the-art methods to address the issue of seafloor macro-litter pollution. The overview includes the following topics: the monitoring of macro-litter on the seafloor, the identification of possible litter accumulation hot spots on the seafloor through numerical models, and seafloor litter management approaches (from removal protocols to recycling processes). The article briefly analyzes the different approaches to involve stakeholders, since the marine litter topic is strongly related to the societal engagement. Finally, attempting to answer to all the critical aspects highlighted in the overview, the article highlights the need of innovative multi-level solutions to induce a change toward sustainable practices, transforming a problem into a real circular economy opportunity.

“…That procedure would increase the cost of required equipment and the production of pyrolysis oil. Blazsó (2006) and Lin, Huang, Luo et al (2010) also showed that pyrolysis of mixed PW containing PVC released hydrogen chloride which caused not only corrosion of the equipment, but also the formation of organochloride compounds in hydrocarbons. Wu et al (2014) showed that the pyrolysis of PVC leads to the production of dioxins which are highly toxic environmental persistent organic pollutants (Berg et al, 2006).…”

1 Fakultet za inženjerski menadžment, luka@latinovic.rs Apstrakt: Ključni problemi recikliranja plastičnog otpada u Srbiji su neadekvatna zakonska regulativa i niska otkupna cena otpadne plastike koja ne predstavlja podsticaj za njeno sakupljanje u većoj meri. Ovaj rad predlaže metod za recikliranje plastike koji se bazira na pirolitičkoj konverziji plastičnog otpada u supstitute goriva kao primarni način reciklaže. Metod se ogleda u više različitih smernica za njegovu primenu. One su detaljno objašnjene i prikazane u ovom radu. Ukoliko bi zakonodavac prepoznao ovaj metod recikliranja kao društveno odgovorno poslovanje i uneo određene izmene u zakonskoj regulativi, i ukoliko bi navedene smernice bile ispoštovane, implementacijom ovog metoda mogao bi se stvoriti prostor za veću otkupnu cenu plastičnog otpada. Ekonomski posmatrano, viša cena otkupa povećala bi ponudu, odnosno podstakla sakupljanje plastičnog otpada u većoj meri što bi imalo pozitivan ekološki efekat uz ekonomsku opravdanost. Ključne reči:Recikliranje plastike, piroliza, zamena za dizel, ekološki. Abstract:The key problems of plastic recycling in Serbia are inadequate legislation and low purchase price of plastic waste, which is a poor incentive for plastic waste collecting. This paper suggests the method for plastic waste handling in Serbia by means of pyrolytic conversion into fuel substitutes as primary recycling method. It is reflected in several guidelines for its application, which are explained in detail, proved and given in this paper. If the state recognized this method as a socially responsible business by introducing certain legal regulation changes and if the above guidelines were followed, the implementation model could make a room for a higher purchase price of plastic waste. In economic terms, higher price would increase supply by encouraging the collection of plastic waste to greater extent, which would have a stronger environmental impact with economic justification.

“…Pyrolysis is a suitable recycling technique for converting the plastic waste into monomers, fuels or other valuable materials by thermal cracking processes. This method can be applied to transform both thermoplastics and thermosets, moreover, it is suitable for the treatment of plastic wastes mixtures [1]. Thermal cracking of seven components mixed plastics into oils/waxes was investigated by thermal cracking process.…”

Abstract. The thermal and catalytic degradation of a plastic wastes mixtures using two types of natural clays catalysts has been carried out in order to obtaining liquid oils with potential use in the chemical industry. Thus, the polymer waste mixture (PWM) of polystyrene (PS), poly(ethylene terephthalate) (PET) and poly(vinyl chloride) (PVC) were thermally degraded at 420 °C in absence and presence of studied catalysts in mass ratio 1:10, catalyst/PWM. The catalysts were characterized by N 2 adsorption-desorption isotherms (BET), Scanning Electron Microscopy (SEM) and Fourier-transform infrared spectrometry (FTIR) for determined the structural and textural properties. The degradation of plastic wastes produces gases, liquids and solid residue products. The effect of the catalyst types on the yields and distribution of end-products obtained by thermal and catalytic degradation of mixed plastic waste has been studied. The yields of liquid oils fractions were calculated between 54.98 wt.% and 62.18 wt.%. The liquids and solid products were analyzed by different analytical techniques: gas chromatography mass spectrometry (GC-MS), ultraviolet visible spectroscopy (UV-Vis) and/or FTIR, in order to establish the chemical compositions. The GC-MS results showed that the liquid products contain in principal monoaromatic compounds like styrene, toluene, ethylbenzene or α-methylstyrene. The FTIR and UV-Vis spectra of products indicated the specific vibration bands or transitions between electronic energy levels of the functional groups of the constituent compounds.
