Everything about Waga Energy
Landfill gas is a complex mixture of biogas, air and volatile organic compounds, mainly composed of methane and carbon dioxide. Converting it into biomethane is a major technical challenge, requiring a thorough understanding of its characteristics in order to optimise injection into natural gas networks.
Biomethane is a renewable substitute for natural gas, produced from organic waste, and plays a crucial role in the energy transition. Its production and injection into gas networks help reduce greenhouse gas emissions, while contributing to the decarbonisation of the economy.
The virtual tour of the WAGABOX® unit illustrates the process of transforming landfill gas into biomethane, detailing each stage from the waste cells to the point of injection into the gas network. It highlights the technical innovations used to maximise the efficiency and minimise the environmental impact of this technology.
Biomethane
Biomethane is a renewable alternative to fossil natural gas. Primarily composed of methane (CH₄), biomethane is produced by upgrading biogas generated through the fermentation of organic matter.
Biogas
Biogas is a mixture of methane (CH₄) and carbon dioxide (CO₂) produced by the fermentation of organic matter in an anaerobic environment. To convert it into biomethane, the methane must be separated from the carbon dioxide.
Landfill Gas
Landfill gas is generated naturally as organic matter breaks down at landfill sites. It consists of biogas, air (oxygen and nitrogen), and various other pollutants in varying proportions.
Methane
Methane (CH₄) is a highly combustible gas found in both natural gas and biomethane. It is also a potent greenhouse gas, with atmospheric concentrations more than doubling over the past two centuries.
Natural Gas
A fossil-based hydrocarbon gas mixture consisting primarily of methane. Extracted by drilling, this fossil gas is used as a source of energy (for heating or as fuel for vehicles).
