Solar-driven reforming of solid waste for a sustainable future

In this Review, we focus on PR of real waste, which increases the process complexity, and improves its economics and sustainability

Scholarcy highlights

  • Today’s industrialised economies feature a linear “take-make-waste” model of resource extraction, consumption and disposal. This linear system has financial incentives, our increasingly urgent need to preserve finite resources and minimise greenhouse gas emissions will require a rapid transformation of the production and use of materials and energy
  • Up to eighteen times more waste is produced industrially than municipally, but due to the scarcity of data on global industrial waste composition and disposal, we focus primarily on municipal solid waste unless stated otherwise
  • Incineration is used to generate energy from 22% of MSW in high income countries, it will not be discussed here as we focus on the production of fuels and valueadded chemicals
  • With continued technological developments and application in tandem with other renewable technologies, photoreforming has the potential to generate clean fuels and mitigate waste, and contribute to the circular and sustainable flow of materials and energy in a carbon-zero future
