Landfill & biogas upgrading
Landfill gas as an energy source
DMT’s Carborex® & Sulfurex® for upgrading landfill gas
Landfill is the oldest form of waste disposal. Waste was simply disposed in piles or thrown in pits and it was only in the 1940’s that we began covering the landfills. But still landfills make up for a large portion of the human-related methane emission. Typically on a landfill you will find the same bacteria present in an anaerobic digester making landfills a source of methane emissions.

Landfill gas (LFG) is produced by the decomposition of organic material in landfills and is considered a by-product. The main component in LFG is methane (CH4) and carbon dioxide (CO2) but it also contains other different gasses. About 2 to 10 percent of LFG (landfill gas) consists of nitrogen, oxygen, ammonia, sulfides, hydrogen, VOC’s and siloxanes.
Landfill gas quality
The quality of landfill gas for biogas upgrading varies. Contributing factors include oxygen content, the amount of moisture, temperature, the type of waste present in the landfill and the age of the landfill. Landfill methane can be tapped, captured, and used as a fairly clean renewable energy source for generating electricity or heat. Further treated, the landfill gas can be upgraded to a high quality and high efficient energy source.
Upgrading to Green Gas – Biomethane
Producing biomethane, or sometimes referred to as green gas, from gas from landfills, reduces odour as well as health and safety hazards associated with the emissions. Additionally, biogas upgrading from LFG reduces greenhouse gas emissions, generates revenue and creates local jobs.
