Summary

More than eight billion tons of plastic waste has accumulated worldwide over the past 50 years. The majority (80%) of the waste goes directly into landfills and 3% ends up in the oceans. At the current rate, we will end up having more plastic than fish in the ocean by 2050. Plastics are persistent in the environment and degrade slowly (over a century), releasing fragments, microplastics, and toxic chemicals into our lands, rivers, and oceans. In particular, single-use packaging, textile, and composite plastic such as e-waste are attributed to more than 50% of the plastic waste.
The overall goal of this special issue is to shed light on the area of plastic waste management. Topics of interest include but not limited to mechanical recycling, chemical recycling, biodegradation, micro-/nano-plastic, characterization methods for plastic waste, policy analysis, techno-economic and lifecycle analysis of plastic waste management. New knowledge reported in this special issue will provide guidance for sustainable development as well as future manufacturing of plastic products.

Published Papers
  • Life Cycle Assessment of Recycling High-Density Polyethylene Plastic Waste
  • Abstract Increasing production and use of various novel plastics products, a low recycling rate, and lack of effective recycling/disposal methods have resulted in an exponential growth in plastic waste accumulation in landfills and in the environment. To better understand the effects of plastic waste, Life Cycle Analysis (LCA) was done to compare the effects of various production and disposal methods. LCA shows the specific effects of the cradle-to-grave or cradle-to-cradle scenarios for landfill, incineration, and mechanical recycling. The analysis clearly indicates that increasing recycling of plastics can significantly save energy and eliminate harmful emissions of various carcinogens and GHGs into the… More

  • Glycolysis Recycling of Waste Polyurethane Rigid Foam Using Different Catalysts
  • Abstract Dramatically increasing waste polyurethane rigid foam (WPRF) draws the attention of the world. A mixture of ethylene glycol (EG) and diethylene glycol (DEG) is used as glycolysis agents. WPRF was subjected to alcoholysis using different catalysts which are titanium ethylene glycol and potassium hydroxide to obtain recycled polyol, respectively. The effect of a different catalyst on the viscosity and hydroxyl value of recycled polyol is discussed. The regenerated polyurethane (RPU) is performed using the recycled polyol. Infrared spectrum, compressive strength, apparent density, water absorption, scanning electron microscope, and thermogravimetric analysis are carried out to investigate the effect of WPRF degradation… More

  • Synthesis and Characterization of Thermoplastic Poly(Ester Amide)s Elastomer (TPEaE) Obtained from Recycled PET
  • Abstract A series of thermoplastic polyester elastomer (TPEE) and thermoplastic poly(ester amide)s elastomer (TPEaE) copolymers were obtained by depolymerizing PET (polyethylene terephthalate) by which the waste PET can be efficiently recovered and recycled into value-added products from a practical and economical point of view. The structure of TPEE and TPEaE was identified using nuclear magnetic resonance (NMR) and Fourier transform infrared spectroscopy (FT-IR). Differential scanning calorimetry (DSC) data showed that the melting temperature (Tm) decreased with the amide content increased. The glass transition temperature (Tg) was increased as introducing the amide group, and the formation of amide-ester and amide-amide hydrogen bonds… More
