biogas higher efficiency

Cat® Gas Gensets help convert Biogas to clean energy

Byproduct gases from agricultural, food processing and industrial processes are captured to fuel Cat® low-energy fuel generators. These generators are engineered to handle fuel with variations in methane content typical of biogas operations. And the energy you generate is nearly free power for your facility.

Durable and reliable biogas can yield significant long-range savings, in addition to being environmentally responsible. By tapping into biogas resources with proven Caterpillar technology, many industries can:

  • Reduce carbon emissions through the destruction of naturally occurring methane
  • Reclaim valuable land space normally used for purifying organic wastewater
  • Eliminate odor and pest issues that are caused by the decomposition of organic material
