Waste plastic to energy storage materials: a state-of-the-art review

Abstract

Recycling plastic waste efficiently and cleanly is one of the key ways to reduce environmental pollution and carbon emissions. At present, the disposal methods of waste plastics mainly include landfill,...

Plastic Waste Recycling─A Chemical Recycling Perspective

“…In addition to the energy received, plastic waste incineration offers several advantages over landfill deposition: Reduction of the waste mass Incineration can transform harmful substances Obtained incineration slag (inorganic fillers and residue) is inert and can be deposited or used for road construction Easiest end-of-life use of unrecyclable plastic, like Mixed, coextruded, composite structured, bonded, or laminated to other materials plastics Extensively degraded polymers Possibly contaminated plastics from medical use, hazardous-goods packages, agriculture use, etc. The incineration of plastic is also improving in terms of efficiency , and lower emissions due to new technologies such as carbon capture and storage methods. − Additionally, strategies to produce useful products that function as carbon capture materials are being investigated. These methods can generate porous carbon with hierarchical, tubular (Carbon Nanotube – CNT), granular, or template structures from plastic waste. , CNTs, in particular, have gained importance in recent years due to their exceptional mechanical, electrical, thermal, and optical − properties.…”

“…These methods can generate porous carbon with hierarchical, tubular (Carbon Nanotube − CNT), granular, or template structures from plastic waste. 58,59 CNTs, in particular, have gained importance in recent years due to their exceptional mechanical, 60 electrical, 61 thermal, 62 and optical 63−66 properties. Despite the aforementioned advantages, incineration can also produce harmful substances remaining in the bottom or fly ash after incineration.…”
