Disposable face masks

Application

  • Used to develop disposable face masks

Description

Scientists from China and the USA have studied the co-pyrolysis of two waste streams: bamboo residue and used disposable face masks. face masks are meant to be used once and then disposed of, their production and use have caused vast amounts of waste to enter the environment. Disposable face masks are constructed of mixtures of materials, mainly non-woven polypropylene in multi-layered arrangements. Like most waste, disposable face masks are typically disposed of in landfills, it reduces the volume of waste, release of hazardous emissions and toxic chemicals into the environment.

Pathway Description:

The project utilized co-pyrolysis, a thermal decomposition process, to convert bamboo residue and disposable face masks into value-added products. This process involved heating the materials in the absence of oxygen, enabling synergistic interactions between bamboo's biomass and the polymer components of facemasks.
