Example Companies​

  • Sistema.bio - Provides biodigesters that convert organic waste into biogas and biofertilizer.
  • HomeBiogas - Develops small-scale biogas systems for households and small farms.
  • Biogas Engineering - Specializes in the design and construction of biogas plants.
  • Envirofit - Creates clean cooking solutions, including biogas stoves.

Overview​

  • Biogas: Produced from the breakdown of organic matter like food waste, manure, and sewage through anaerobic digestion.
  • Application: Used for cooking, heating, and powering vehicles.
  • Greenhouse Gas Reduction: Replaces traditional fuels, leading to fewer greenhouse gas emissions.
  • Leaders in Biogas Promotion: Biogas industry, United Nations, World Bank.

Progress Made​

Significant advancements in biogas technology have led to reduced greenhouse gas emissions and increased adoption of biogas systems:

A new method can convert 95 percent of biogas into green fuel methanol without adding hydrogen, making green methanol much cheaper to produce than before.
