ClearThermal degradation kinetics of real-life reclaimed plastic solid waste (PSW) from an active landfill site: The mining of an unsanitary arid landfill
This study analyzed plastic waste reclaimed from an active landfill to determine how it degrades thermally for potential conversion into fuel or other products. Understanding the thermal behavior of landfill plastic waste is relevant to recovering value from discarded plastics rather than leaving them to fragment into microplastics.
An overview of microplastics characterization by thermal analysis
This review explores the potential of thermal analytical techniques - including thermogravimetry and pyrolysis-GC/MS - for identifying and characterizing microplastics in environmental samples, covering both manufactured primary microplastics and degradation-derived secondary ones. Thermal methods offer advantages for bulk quantification and polymer identification that complement spectroscopic approaches.
