Each of these conferences focused on special issues covered by the Journal of Material Cycles and Waste Management. The topics included thermal processes with and without catalysts, wet processes in various solvents, the dehydrochlorination of PVC, mechanical recycling and separation techniques, as well as the treatment of biomaterials. This review is a compilation of the most interesting and important developments discussed at the ISFR during the last decade. Since the symposium has consistently had its focus on special issues published in the Journal of Material Cycles and Waste Management , it has provided us with the opportunity to review the major challenges and perspectives of the day, reflecting on the special issues and related publications from other journals. One issue consistently given a lot of attention over the years is the dehalogenation of waste plastics, which can be divided into two large fractions, municipal waste and waste electric and electronic equipment WEEE.

Waste plastics contribute to serious environmental and social problems, such as the loss of natural resources, environmental pollution, and depletion of landfill space, but they also create demands on the environmentally-oriented part of the society. Feedstock recycling of scrap polymers by thermal and chemical methods is well known and environmentally accepted. The paper presents the results of thermodynamic analysis of the conversion of polyolefins in a fuel-like mixture of hydrocarbons using thermal cracking in a new type of tubular reactor with molten metal. Evaluation of the efficiency of the process was based on exergy calculations. Calculated exergy efficiency was ca. It means that feedstock recycling of waste is better from an energetic and environmental point of view than other processes, particularly incineration. It is hard to estimate global production of plastics excluding fibers especially when available data vary [ 1 , 2 ].

Pyrolysis based biorefineries have great potential to convert waste such as plastic and biomass waste into energy and other valuable products, to achieve maximum economic and environmental benefits. In this study, the catalytic pyrolysis of different types of plastics wastes PS, PE, PP, and PET as single or mixed in different ratios, in the presence of modified natural zeolite NZ catalysts, in a small pilot scale pyrolysis reactor was carried out. The gas chromatography-mass spectrometry GC-MS analysis of oil showed a mixture of aromatics, aliphatic and other hydrocarbon compounds. FT-IR results showed clear peaks of aromatic compounds in all liquid oil samples with some peaks of alkanes that further confirmed the GC-MS results. The liquid oil has a high heating value HHV range of

Халохот проверил оружие, решительно направился вперед и осмотрел площадку. Левый угол пуст. Следуя плану, он бросился в проход и, оказавшись внутри, лицом к правому углу, выстрелил.

    Pyrolysis is a recycling technique converting plastic waste into fuels, monomers, or other valuable materials by thermal and catalytic cracking.
