An Introduction to PET (polyethylene terephthalate) PET (also abbreviated PETE) is short for polyethylene terephthalate the chemical name for polyester PET is a clear strong and lightweight plastic that is widely used for packaging foods and beverages especially convenience-sized soft drinks juices and water Virtually all single-serving and 2-liter bottles of carbonated soft drinks and getic and material recycling methods ultimately lead to a downcycling of PET In contrast chemical recycling methods offer the pos-sibility of re-introduction of PET into the material cycle without loss of quality by de-polymerizing PET-waste into monomers These monomers are used for re-polymerization Most frequently applied meth-


Polypropylene is currently one of the fastest growing polymers Much of this growth is attributed to polypropylene's ability to displace conventional materials (wood glass metal) and other thermoplastics at lower cost Polypropylene (PP) is a tough rigid plastic and produced in a variety of molecular weights and crystallinities Polypropylene is made from the polymerization of propylene

Polypropylene can be combined with other materials as can polyethylene Rubber for example can be added to make it more pliable One of the exciting additives that is added to polypropylene are minerals These minerals allow a polypropylene sheet to become a synthetic paper synthetic paper is essentially plastic paper It can be easily printed on It can be folded hot stamped die cut

Making a mark on polypropylene recycling Fluorescent markers aid in recycling polypropylene Subscribe February 7 2020 Edward Kosior Municipal Recycling While polypropylene (PP) is the most versatile and easiest to recycle polymer and one of the most widely used materials in packaging for consumer goods this packaging is not widely recycled Additionally PP is virtually nonexistent as a

Polypropylene (PP) Margin Report ICIS pricing's weekly European PP margin report is designed to complement ICIS's highly regarded pricing data It assesses producer cash costs and cash margins for PP by modelling raw material and key variable manufacturing costs co-product credits and product yields across the business from feedstock naphtha or propane through propylene to PP

17/04/2008Introduction Food contact materials are all materials and articles intended to come into contact with food such as packaging and containers kitchen equipment cutlery and dishes In the European Union plastic is one of the most common food contact materials These may be made exclusively of plastic or they may consist of a plastic layer on top of another material such as metal or

Introduction The amount of waste of polystyrene (PS) foams is increasing in last years due to the increase of their use in isolation protecting storing and serving many different food products Continuous accumulation of waste plastics leads to serious problems all over the world (Seung-Soo and Seungdo 2004) Recycling of this waste has recently received significant attention all over the

Introduction In the past 30 years global plastic consumption has multiplied by 10 reaching an estimated value of 100 M tonnes per year However this technological development has not foreseen the implications of product recycling The recycling of these materials is a must given their limited or no biodegradability and the fact that they cause the depletion of a non-renewable resource like
