Poly(ethlyene terephthalate) waste from a local market was depolymerized by ethylene glycol (EG) in the presence of Lewis acidic ionic liquids [Bmim]ZnCl3 and the qualitative analysis showed that bis(hydroxyethyl) terephthalate was the main product. Compared with ionic liquid [Bmim]Cl, the Lewis acidic ionic liquids showed highly catalytic activity in the glycolysis of poly(ethylene terephthala...

Over 359 million tons of plastics were produced worldwide in 2018, with significant growth expected the near future, resulting global challenge end-of-life management. The recent identification enzymes that degrade previously considered non-biodegradable opens up opportunities to steer plastic recycling industry into realm biotechnology. Here, sequential conversion post-consumer polyethylene te...

Recently, the demands for the production of many different types of plastic wastes are greatly growing that subsequently, lead to the serious challenges in environmental considerations. Since, these materials are rarely resolved by microorganisms, hence, their recycling to the useful materials is crucial. In the present study, we used a solution electrospinning technique to synthesize nano/micr...

Polyethylene terephthalate (PET) bottle recycling is a highly automated task; however, manual quality control required due to inefficiencies of the process. In this paper, we explore automation sub-task, namely visual detection, using convolutional neural network (CNN)-based methods and synthetic generation labelled training data. We propose pipeline tailored for transparent crushed PET detecti...

Supercritical ethanolysis (scEtOH) is a method that allows the production of monomers, e.g., diethyl terephthalate (DET), from Polyethylene terephthalate PET chemical recycling. The use of the ionic liquids (ILs) such as 1-n-butyl-3-methylimidazolium tetrafluoroborate ([Bmim][BF4]) as a catalyst has advantages in such processes by enhancing the yield at reduced times, as shown in previous work ...

Ligament reconstruction is an effective therapy for anterior cruciate ligament (ACL) rupture. Polyethylene terephthalate (PET) artificial ligaments have recently gained popularity in clinical ACL reconstruction for its advantage in the improvement of keen function. However, the application of PET in clinical treatment is limited by its poor bioactivity and biocompatibility. Recently, bone marro...

Fast fashion trends lead to significant quantities of textiles produced and discarded, its waste is incinerated or landfilled due a lack recycling technologies for mixed textiles. Recycling by hydrothermal liquefaction (HTL) novel approach produce bio-oil monomers, as no prior sorting color removal required. Herein, post-consumer polyester (polyethylene terephthalate (PET)) cotton garments were...

Abstract This paper aims to thoroughly analyze the effect of polyethylene terephthalate (PET) plastic aggregate on concrete compressive strength using a meta-analysis. Forty-three datasets for containing PET coarse and 60 data sets fine were collected. The input variables used percentage nominal maximum size along with mix proportions. Main plots, contour surface plots expressions presented dem...

Degradation of polyethylene terephthalate (PET) plastics by the traditional technologies usually requires high energy consumption and encounters poor product selectivity. Herein, we report photoconversion PET into carbon dioxide with 100% selectivity in-plane heterostructured NiO/Fe2O3 nanosheets in pure water under normal temperature pressure. High-resolution transmission electron microscopy, ...
