Poly(ethylene terephthalate) PET, is a material of great commercial importance, in the form of fibers, bottle resin, and to a lesser extent, as a molding resin. In 1990, the annual world production of PET fibers was about 9 million metric tons and the annual world production of bottle resin was 1.2 million metric tons (1). Owing to the widespread use of PET, investigations of the decomposition ...

Biomass use and recycling are among the few options to reduce greenhouse gas (GHG) emissions of growing plastics sector. The bio-based plastic polyethylene furanoate (PEF) is a promising alternative terephthalate (PET), in particular for small bottle applications. For first time, we assessed life cycle global warming potential (GWP) 250 mL PET PEF bottles over multiple mechanical (MR) chemical ...

A systematic study of solid state polymerization (SSP), concerning the melt extruded blend of poly(ethylene terephthalate)/polycarbonate (catalyzed PET/PC, 80/20 wt %), as a function of temperature range (180-190°C) for a fixed time (6 h) is presented. The materials obtained were evaluated by differential scanning calorimetry (DSC), thermogravimetry/derivative thermogravimetry (TG/DTG), optical...

Sustainability is one of the main goals development policy and also progressively gaining importance in wine industry. The peculiar draught market strongly influenced by it. current competitive conditions sector evolution consumption styles have led to an increasing need for more accurate management strategies analysis activities determine performance wineries.
 This study aims analyse bot...

In this work, we reported the investigation of diamond-like carbon (DLC) coating on inner surface polyethylene terephthalate (PET) bottles by Microwave Plasma Enhanced Chemical Vapor Deposition to improve their barrier properties. We used 2.45 GHz microwave generate plasma, acetylene (C2H2) and argon (Ar) were as monomer gas diluted gas. The effects plasma process parameters deposition uniformi...

Abstract Encountering weak fine-grained soil presents a significant challenge during highway construction. The conventional approach to address this involves incorporating calcium-based stabilizers, particularly cement, for stabilization. However, despite its widespread use, the application of cement stabilization has adverse environmental consequences. Accordingly, finding alternative methods ...

The objective of the study is to investigate influence Polyethylene Terephthalate (PET) recycled plastic bottle fibers on compressive strength and cracking concrete. In this study, two types fiber are used: straight zigzag whose length aspect ratio 40 mm respectively. 0, 0.75, 1.25% volume fractions replacing coarse aggregates used in investigation. According ACI 211.1-91, design mixing 1:2:3 f...
