Identification of drivers of global trade in plastic waste based on GCA and ISM-MICMAC model: Taking China, USA and South Africa as cases.

Plastic waste's dual characteristics of "resource" and "pollution" led to the prevalence of trade. The Global Plastic Waste Trade Network (GPWTN) is heterogeneous, and its structure is susceptible to the influence of key countries within it. However, there is a shortage of research on the key countries and trade drivers influencing GPWTN evolution.

Mechanistic exploration of polytetrafluoroethylene thermal plasma gasification through multiscale simulation coupled with experimental validation.

The ever-growing quantities of persistent Polytetrafluoroethylene (PTFE) wastes, along with consequential ecological and human health concerns, stimulate the need for alternative PTFE disposal method. The central research challenge lies in elucidating the decomposition mechanism of PTFE during high-temperature waste treatment. Here, we propose the PTFE microscopic thermal decomposition pathways by integrating plasma gasification experiments with multi-scale simulations strategies.
