Recycling of Plastics in the United States: Plastic Material Flows and Polyethylene Terephthalate (PET) Recycling Processes.

ACS Sustainable Chemistry and Engineering, 2022
As efforts are made toward establishing a circular economy that engages in activities that maintain resources at their highest values for as long as possible, an important aspect is understanding the systems which allow recycling to occur.

Polyethylene terephthalate (PET) waste to carbon materials: Theory, methods and applications

Journal of Analytical and Applied Pyrolysis, 2022
Polyethylene terephthalate (PET polymer) is the main ingredient in clear bottles containing water and other liquids such as hand sanitizers. Due to the increasing use of these disposable bottles, especially during the COVID-19 pandemic, the production of

Hydrolysis of waste polyethylene terephthalate catalyzed by easily recyclable terephthalic acid.

Waste Management, 2021
Hydrolysis of polyethylene terephthalate (PET) is an efficient strategy for the depolymerization of waste PET to terephthalic acid (TPA), which can be used as a fundamental building block for the repolymerization of PET or for the synthesis of ...

Photoinjection into polyethylene terephthalate

Canadian Journal of Physics, 1977
We have measured the photocurrents injected into polyethylene terephthalate from evaporated aluminum electrodes in the wavelength range 475–300 nm following a careful depolarization of the specimens. The yield curves give linear plots of (yield)1/2 against photon energy. The threshold energy is [Formula: see text].

Easily recoverable and reusable p-toluenesulfonic acid for faster hydrolysis of waste polyethylene terephthalate

Green Chemistry, 2022
Common technologies for waste polyethylene terephthalate (PET) hydrolysis generally use strong acids or alkalis as catalysts; however, these processes are costly and generate a large amount of acid, alkali, and...

Solubility of Polyethylene Terephthalate

Nature, 1965
IT is generally considered that polyethylene terephthalate is soluble only in a restricted range of rather specialized organic liquids, such as o-chlorophenol, tetrachlorethane/phenol, etc. It is the purpose of this report to describe conditions under which this range may be extended.
