Abstract — The growing worldwide production of synthetic plastics leads to increased amounts plastic pollution. Even though microbial degradation is known be a very slow process, this capacity has been found in many bacteria, including invertebrate symbionts, and microscopic fungi. Research field mostly focused on polyethylene, polystyrene, polyethylene terephthalate (PET). Quite an arsenal dif...

Thermo-chemical treatment (TCT) such as pyrolysis is getting recognized as a valid route for (i) materials and valuable products and petrochemicals recovery; (ii) waste recycling; and (iii) elemental characterization. Pyrolysis is also receiving renewed attention for its operational, economical and environmental advantages. In this study, samples of polyethylene terephthalate (PET) and polystyr...

Recycling is one of the most efficient methods for environmental friendly waste management. Among municipal wastes, plastics are the most common material that can be easily recycled and polyethylene terephthalate (PET) is one of its major types. PET material is used in consumer goods packaging such as drinking bottles, toiletry containers, food packaging and many more. Usually, a recycling proc...

A suitable method to functionalize the surface of polyethylene terephthalate (PET) consists in the chemical treatment with different amines such as triethylenetetramine (TETA), or tetraethylenepentamine (TEPA). The paper describes the influence of PET surface amination on the mechanical and water-sorption properties. Superficial chemical treatment involves micro-structural changes such as molec...

Post-consumer PET (polyethylene terephthalate) bottles have been recycled into fiber and sheet products ever since the Containers and Packing Recycling Law came into effect in 1997. There has been a growing need, however, for a chemical recycling process. In this process, post-consumer PET bottles are recycled into monomers that can be used as feed stocks for the recycled production of PET bott...

The recycling process is the best way to manage waste polymers. From an economic standpoint, more investigation needed of whole enhance competitiveness in these systems. A first step improved interaction and interfacial adhesion blends. Polyethylene (PE) polyethylene terephthalate (PET) are incompatible polymers, so their blends general have poor properties. Compatibilization thus a necessary o...

In this investigation, rheological properties of three different polymer-modified bitumen compounds containing recycled polyethylene terephthalate (R-PET), crumb rubber (CR) and poly (styrene-butadiene-styrene) (SBS) are evaluated and compared. The modified samples were tested by a dynamic shear rheometer (DSR) where complex modulus (G*), phase angle (δ) and rutting resistance (G*/Sinδ) of spec...

This paper presents a comparative study of the thermal, mechanical, chemical and surface properties of the biodegradable polymer polylactic acid (PLA) and the petroleum based polymer polyethylene terephthalate (PET). The study shows how the material properties of these two polymers influence the processing conditions used during manufacture. The polymer properties were compared using differenti...

Today, the economic consumption of biodegradable polymers is of capital importance in many applications. One of the most commonly used biopolymers is polylactic acid (PLA). The printability of the biodegradable film has not been fully investigated. This work tested the printability of polylactic acid (PLA) films and compared the print qualities to common packaging films like low density pol...
