Highland collects landfill gas produced in landfills and converts the gas into environmental and economic benefits. It can create these benefits in a number of ways.

  • The collected landfill gas can be utilized as a fuel to produce green renewable energy.
  • The landfill gas can be processed and purified to upgrade to pipeline quality (i.e. natural gas), thus creating “renewable natural gas”.
  • The landfill gas can be utilized directly by an industrial host as fuel to augment or replace fossil fuels.
  • Landfill gas can be upgraded to pipeline quality natural gas, compressed and utilized as vehicle fuel.

International experience

Highland has conducted feasibility assessments for potential landfill gas projects in: Brazil, China, Costa Rica, Guatemala, Honduras, India, Mexico and the Philippines.

Landfill gas is created in landfills when the organic material decomposes. One of the main components of this gas is carbon dioxide (CO2).

CO2 is a common man-made gas and the major contributor to global warming. The other principle component of landfill gas is methane (CH4), a colorless, odourless and highly explosive gas. Methane has 21 times the global warming capacity of carbon dioxide. One of the major sources or methane released from human activities originates from municipal solid waste landfills.

Responsible waste management requires a long term commitment.
A landfill can generate up to 125 cubic meters (m3) of methane per tonne of waste over a period of 10 to 40 years.

If not properly managed, landfill gas can create any number of environmental, health and odour problems.
