Request PDF | PET recycling: Evaluation of the solid state polymerization process | Many studies have been carried out to make bottle-to-bottle recycling feasible. One of the difficulties found is ...
Chemical recycling of Polyethylene Terephthalate (PET) has gotten great attention today. Aminolysis, one of the chemical recycling methods, is the degradation of polyesters using primary amines that attack its functional group. It is not much explored as a commercial recycling technique among the chemical recycling methods. This review …
The recycling of plastic waste into new useful building construction products will be a great advantage In this analysis, the shredded PET waste gathered from the recycling center was heated to ...
In this paper we review an interesting method of PET recycling, i.e. chemical recycling; it is based on the concept of depolymerizing the condensation polymer through solvolytic chain cleavage into low molecular products which can be purified and reused as raw materials for the production of high-quality chemical products. In this work our attention …
The recycling of post-consumer PET (POSTC-PET) as a technology is a cross-disciplinary practice with many fields. of science involved. These include polymer chemistry and physics, process ...
This book is essential reading for anyone in industry or academia requiring up-to-date information on technical developments in the recycling of PET, the market and regulatory framework within ...
Solid waste generation especially from plastics increase every year due to the current consumption habit in the society. The improper disposal of plastics has been a major concern to environment as they are not easily degradable. In this study, energy derived from Polyethylene Terephthalate (PET) plastic bottle recycling process were …

Background With a growing global population, the generation of plastic waste and the depletion of fossil resources are major concerns that need to be addressed by developing sustainable and efficient plastic recycling methods. Biocatalytic recycling is emerging as a promising ecological alternative to conventional processes, particularly in …
With the European Green Deal, the importance of recycled products and materials has increased. Specifically, for PET bottles, a high content of recycled material (rPET) is demanded by the industry and consumers. This study was carried out in a lab environment replicating real-life industrial processes, to investigate the possible impacts …
The Tomra Recycling Sorting business unit of Norway-based Tomra Systems ASA says it has identified two popular applications at North American material recovery facilities (MRFs) for its deep learning or artificial intelligence (AI)-based GAINnext sorting device.. Tomra says the PET Cleaner and Paper Cleaning applications for GAINnext …
Plastic makes our society more practical and safer. It is hard to consider eliminating plastic in some sectors, such as the medical field. However, after use, plastic waste becomes a global problem without precedents, and when not properly disposed of, it can cause several socio-environmental problems. Some possible solutions are …
The current public debate on plastic debris also triggered the revision of PET recycling technologies. This Research Article focuses on the chemical recycling of PET by means of methanolysis ...
Due to the increasing production of plastic soft drink bottles, accompanied by the accumulation of plastic waste in landfills, our society is encouraging the development …
Abstract. Polyethylene terephthalate (PET) stands out as the most widely recycled plastic globally. However, in the Philippines, the processes associated with PET recycling, particularly the transportation of PET bottles from collectors and consolidators to processing plants, demand significant time, monetary resources, and effort due to the …

Production of polyethylene teraphtalate (PET) fiber in the world is increasing every year and reached to an amount of about 20 million tons a year in 2001. The wastes occur in the production of PET fiber in the amount of about 3–5% of total production. The PET does not degrade for a long time in nature. Since PET is a derivative of petroleum, the wastes of …
(a) The hydrolysis kinetics of PET based on the shrinking core model (inset). (b) The volcano-shaped correlation between the reaction rates and the Hammett constants (σp) for different substituents.
Avantium, a renewable chemistry company based in the Netherlands, plans to open a plant later this year that will enable commercial-scale production of a plant-based plastic that can be incorporated into packaging and recycled in traditional polyethylene terephthalate (PET) recycling streams.. Avantium's YXY plant-to-plastics technology …
PET recycling can significantly reduce energy and GHG emissions compared to PET production, with a life cycle assessment (LCA) study showing that it can …
