Sustainable Alternatives to Nondegradable Medical Plastics

Dai-Hua Jiang,
Toshifumi Satoh,
Shih Huang Tung
et al.

Abstract: In light of the global climate crisis and commitments toward net-zero carbon emissions, this Perspective evaluates the current status of developments in recycling methods and bioplastics to identify long-term sustainable alternatives. The recycling and product application of major medical plastics, including poly(vinyl chloride) (PVC), polyethylene (PE), polypropylene (PP), and polystyrene (PS), are discussed, and their circular potential is evaluated. Researchers are actively investigating bioplastics to solv… Show more

“…Recycling PVC, as the primarily utilized plastic in terms of volume in medical devices [ 27 , 55 ], is challenging and imposes adverse environmental impacts, especially in the forms of air pollutants and chlorine, which contaminates recycling products and causes equipment corrosion [ 38 ]. These problems are addressed by introducing catalysts, hydrogen chloride inhibitors, or pretreatment processes to increase the efficiency of recycling procedures [ 38 ].…”

“…The quality of pyrolysis products is highly dependent on feedstock characteristics and temperature parameters [ 23 ]. In particular, the complex components and unbalanced proportion of medical waste significantly affect the pyrolysis process and the distribution of products [ 24 ]. In fact, biomass and plastic products account for the largest proportion of medical waste components, more than 60%.…”
