Current Knowledge on Polyethylene Terephthalate Degradation by Genetically Modified Microorganisms

Frontiers in Bioengineering and Biotechnology, 2021
The global production of polyethylene terephthalate (PET) is estimated to reach 87.16 million metric tons by 2022. After a single use, a remarkable part of PET is accumulated in the natural environment as plastic waste.

Synthesis of Highly Conductive Electrospun Recycled Polyethylene Terephthalate Nanofibers Using the Electroless Deposition Method

Nanomaterials, 2021
Plastic bottles are generally recycled by remolding them into numerous products. In this study, waste from plastic bottles was used to fabricate recycled polyethylene terephthalate (r-PET) nanofibers via the electrospinning technique, and high ...

Prediction of terephthalic acid (TPA) yield in aqueous hydrolysis of polyethylene terephthalate (PET)

CoRR, 2022
Aqueous hydrolysis is used to chemically recycle polyethylene terephthalate (PET) due to the production of high-quality terephthalic acid (TPA), the PET monomer. PET hydrolysis depends on various reaction conditions including PET size, catalyst concentration, reaction temperature, etc.

Polyethylene Terephthalate (PET) Biodegradation by Pleurotus ostreatus and Pleurotus pulmonarius

Environmental Monitoring and Assessment, 2022
Abstract Essential properties of Polyethylene terephthalate (PET) such as lightness, high transparency, high mechanical strength, good moisture barrier, high heat resistance, and relatively low cost make it a suitable material for the packaging of natural mineral and soft drink bottles. However, these have contributed significantly to household

Properties of Polyethylene Terephthalate (PET) after Thermo-Oxidative Aging [PDF]

Materials, 2021
The influence of the thermo-oxidative aging semi-crystalline polyethylene terephthalate process on the thermal and mechanical properties was analysed in the article. For this purpose, PET was aged at 140 °C for 21, 35 and 56 days. The research showed that as a result of aging, the amount of the crystalline phase increases by about 8%, which translates ...

Effect of Partial Replacement of Fine Aggregate by Polyethylene Terephthalate on the Characteristics of Mortar [PDF]

JES: Journal of Engineering Sciences
In this study, polyethylene terephthalate (PET) granules were used as a partial replacement for sand in mortar applications as a sustainable alternative material after recycling plastic waste to compensate for the expected shortage of natural aggregates ...

Microbial fermentation of polyethylene terephthalate (PET) plastic waste for the production of chemicals and electricity

, 2021
Ideonella sakaiensis (I. sakaiensis) can grow on polyethylene terephthalate (PET) as the sole carbon and energy source. Previous work has shown that conversion of the hydrolysis products terephthalic acid (TPA) and ethylene glycol (EG) under aerobic ...

Structural basis of terephthalate recognition by solute binding protein TphC

Nature Communications, 2021
The presence of the gene encoding the solute binding protein TphC has been shown to permit the uptake of terephthalate (TPA), which is the breakdown product of Polyethylene terephthalate (PET) plastic.
