Biogas & Landfill Gas is derived from the following sources:
- Landfills
- Digestion of food and agricultural waste
- Digestion in municipal and industrial waste water treatment plants
Contaminant removal or gas upgrading is typically required to take advantage of Biogas & Landfill Gas as an energy source or exhaust it to atmosphere. While the amount and the type of contaminants depend on the source, treatment is primarily determined by the destination of the gas: to Atmosphere via Gas Flaring, to Local Power/Electricity Generation or to Renewable Natural Gas.
To Atmosphere via Gas Flaring
When exhausting Biogas & Landfill Gas to atmosphere, harmful air emissions and odour control are the primary treatment concerns.
To Local Power / Electricity Generation
When reusing Biogas & Landfill Gas as a local energy source, operators have several options for power/electricity generation equipment such as boilers, gas engines, or combined heat & power (CHP) systems. The choice of equipment dictates the level of required treatment.
To Renewable Natural Gas
When upgrading Biogas & Landfill Gas to Renewable Natural Gas (RNG), the treatment specifications are determined by the utility or pipeline company. These can vary based on location.
