Biofuel Production from Municipal Solid Waste

Detailed overview of innovation with sample startups and prominent university research

What it is

This technology involves converting municipal solid waste (MSW), such as food scraps and yard waste, into biofuels. This approach can address waste management challenges while producing renewable energy.

Impact on climate action

Biofuel Production from Municipal Solid Waste within Biofuels enhances climate action by converting organic waste into renewable energy sources. By diverting waste from landfills, this innovation reduces methane emissions and displaces fossil fuels, mitigating greenhouse gas emissions and contributing to a more sustainable and circular economy.

Underlying
Technology

  • Municipal Solid Waste (MSW): MSW includes various waste materials generated by households and businesses, such as food scraps, yard waste, paper, and plastics.
  • Thermochemical Conversion: Processes like gasification and pyrolysis can convert MSW into biofuels. These processes involve heating the waste in the absence of oxygen to break down its complex molecules into simpler compounds that can be used as fuels.
  • Gasification: Gasification converts biomass into a synthesis gas (syngas), which is a mixture of carbon monoxide and hydrogen. Syngas can then be used to produce various fuels and chemicals.
  • Pyrolysis: Pyrolysis converts biomass into a liquid bio-oil, which can be further processed into biofuels.
