• Anaerobic Digestion

    Process that transforms organic waste into raw biogas.

  • Biogas

    Gas produced through Anaerobic Digestion of organic waste, consisting mainly of methane (CH4) and carbon dioxide (CO2), impurities and other pollutants, such as water, hydrogen sulfide (H2S), siloxanes, Volatile Organic Compounds (VOCs), nitrogen and oxygen.

  • Upgrading

    Process of treating biogas to transform it into biomethane.

  • Biomethane

    Biomethane is a gas consisting almost exclusively of methane. It is produced through upgrading of biogas.

  • N2 and O2

    Nitrogen and oxygen. Their presence in landfill gas makes its necessary to perform a cryogenic distillation to be able to produce biomethane.

  • Bio-CNG

    Compressed Natural Gas produced from biomethane.

  • Bio-LNG

    : Liquefied Natural Gas produced from biomethane.

  • BOG

    Boil-Off Gas. It is the fraction of gas produced from evaporation of LNG.

  • LBG

    « Liquid Biogas ». Equivalent to bio-LNG.

  • LBM

    « Liquid Biomethane ». Equivalent to bio-LNG.

  • RNG

    « Renewable Natural Gas ». Equivalent to biomethane.

  • Bio-CO2

    CO2 produced from biogas.

  • NGV

    Natural Gas Vehicle.

  • CNG

    Compressed Natural Gas (fossil origin).

  • LNG

    Liquefied Natural Gas (fossil origin).

  • Gasification

    Process that transforms carbonaceous materials (like wood waste) into synthesis gas (syngas) consisting mainly of methane (CH4), carbon monoxide (CO), carbon dioxide (CO2), and hydrogen (H).

  • Syngas

    Synthesis Gas produced through gasification of carbonaceous materials.
