A focused review on recycling and hydrolysis techniques of polyethylene terephthalate

Polymer Engineering and Science, Journal Year: 2023, Volume and Issue: 63(9), P. 2651 - 2674

Published: June 21, 2023

Abstract Polyethylene terephthalate (PET) is used in textile and packaging industries. The main source of PET production fossil fuels with limited capacity. Also, products are single use that transform into high volumes wastes, causing ecosystem problems. Recycling proposed to confront this challenge. four major recycling techniques mechanical, chemical, pyrolysis, enzymatic. Mechanical, enzymatic have constrained capabilities manage waste. Chemical the potential path expanding waste possibility upcycling addressing dirty streams. Several chemical methods introduced discussed literature. five glycolysis, alcoholysis, aminolysis, ammonolysis, hydrolysis. This review describes depolymerization via these introduces hydrolysis as one can depolymerize an organic‐free solvent environment. Hydrolysis tolerates mixed wastes streams including copolymers. It helps avoid challenges attributed using organic solvents reaction systems. Moreover, produces terephthalic acid, monomer, which has recently gained attention initiative monomer for production. focuses on three forms hydrolysis—alkaline, neutral, by presenting background studies, issued patents, recent trends application

Life cycle assessment of plastic waste and energy recovery

Energy, Journal Year: 2023, Volume and Issue: 277, P. 127576 - 127576

Published: April 25, 2023

Plastics are essential in our economy and everyday life. However, plastic pollution is a global concern. To address this issue, the European Strategy for Circular Economy was adopted January 2018. Attention has been raised to entire life cycle of products, with legislation stating that used throughout design phase manufacturing packaging phases needs be recyclable by 2030. This study evaluates selected material categories technologies carrying out review Life Cycle Assessment (LCA) analysis from literature. The literature carried out, indicator units impact among investigated mid-point methodologies as well conversion factors metrics harmonization were provided finally detailed environmental several types plastics two options waste hierarchy, which through disposal sending landfills incineration energy recovery. disposal, treatment recycling 2.2 tonnes general including non-recyclable delivered facility considered comparison these methods. An assessment comparative advantages each practice conducted. potential recovery highlighted.

Microplastic pollution in the marine environment: A review

Journal of Hazardous Materials Advances, Journal Year: 2023, Volume and Issue: 10, P. 100327 - 100327

Published: May 1, 2023

The quantity of plastic materials produced worldwide is progressively increasing. For instance, annual global production has increased from 1.5 to 390.7 million metric tons 1950 2021. Meanwhile, inefficient management strategies have resulted in huge waste disposal (i.e., the form macro-, micro-, and nanoplastics) environment a hostile manner. In particular, such uncontrollable discarding paves entrance pollution into as microplastics (μPs) after degradation macroplastics. this respect, marine environments are most typical regions prone μP pollution. These ubiquitous emerging pollutants can also adsorb other pollutants, organic materials, toxic heavy metal ions, pathogens, transfer them living organisms. main theme present study compile information on how affects ecosystem, with particular emphasis following key factors: (i) types sources μPs, particularly those entering sinks; (ii) mechanisms leading μPs' degradation; (iii) poisonous effects μPs biota humans; (iv) fate environment, including their transportation routes deposition modes, (v) recent developments characterization, separation, removal environment. presented here would be practical for developing effective risk plans.
