  author={Vanja Spahi{\vc}},
Zaradi narascanja svetovnega prebivalstva in posledicno vecje proizvodnje, uporabe in odlaganja polimernih materialov, je recikliranje le-teh postala nujnost . Polietilen tereftalat (PET) je v tekstilni industriji najbolj uporabljen sinteticni material, kljub temu pa je recikliranje PET-a iz tekstilnih materialov manj raziskano podrocje. V diplomskem delu smo PET vlakna depolimerizirali s postopkom nevtralne hidrolize, stopnjo depolimerizacije pa dolocili s pomocjo titracij. Rezultati so… 


Trend pri razvoju inovativnih embalažnih materialov je v funkcionalizaciji povrsine embalažnih materialov z namenom pridobitve protimikrobnih lastnosti. Zato iz dneva v dan narasca zanimanje za
Chemical Recycling, Kinetics, and Thermodynamics of Poly (Ethylene Terephthalate) (PET) Waste Powder by Nitric Acid Hydrolysis
Hydrolysis reaction of PET waste powder in HNO3 was undertaken in batch process at 88–120°C temperature and 1 atm pressures. Particle size ranging from 50–512.5 μm and reaction time 30–200 min
Research on the Sorting Reclaim System of Municipal Solid Waste Based on the Concept of “Cradle to Cradle”
Abstract In recent years, the output of municipal solid waste (MSW) in China has been increased by 10% annually, and the traditional disposal methods, such as sanitary landfill, incineration and
SYNOPSIS The process of depolymerization of PET resin by EG glycolysis under pressure is investigated. The kinetics of this pressurized depolymerization of PET resin is discussed. It was found that
Research on Flotation Technique of Separating PET from Plastic Packaging Wastes
Abstract Flotation, as one efficient waste plastic separation technology, is an effective method to improve the recycling rate of packaging waste. Polyethylene terephthalate (PET) widely used in
Chemical recycling of post-consumer PET wastes by glycolysis in the presence of metal salts
Abstract Chemical recycling of poly(ethylene terephthalate) (PET) has been the subject of increased interest as a valuable feedstock for different chemical processes. In this work, glycolysis of PET
Kinetics of catalytic glycolysis of PET wastes with sodium carbonate
Abstract The kinetics of glycolysis of poly(ethylene terephthalate) wastes with ethylene glycol to give highly pure bis(2-hydroxyethyl terephthalate) was examined in a batch reactor. An excess of
Manipulation of chitosan binding on the polyethylene terephthalate (PET) surface and study of coatings on poultry meat shelf life-time
The aim of this study was to activate inert PET surfaces in order to introduce the surfaces’ carboxyl groups and to obtain its hydrophilic character, which was important for the chitosan bonding to
Pet Waste Management by Chemical Recycling: A Review
The paper reviews the problem due to the use and disposal of synthetic polymers to the environment and its solutions; in particular poly (ethylene terphthalate). Wide spread application and
Greener routes for recycling of polyethylene terephthalate
Abstract The article reviews the different routes for recycling of polyethylene terephthalate. Chemical recycling processes are divided into six groups: methanolysis, glycolysis, hydrolysis,
