A Renewable and Clean Alternative to Natural Gas<\/h2>

Biomethane is the renewable substitute for fossil natural gas. Composed of methane (CH\u2084), it offers equivalent energy performance and calorific value to conventional natural gas, while significantly reducing the carbon footprint of your operations.<\/span><\/span><\/p>\n<\/div><\/div><\/div>\n\n

Biomethane is obtained by purifying biogas produced from the anaerobic (oxygen-free) decomposition of organic matter. This process occurs naturally in swamps, rice paddies, wastewater treatment plants, or landfill sites, and can also be triggered artificially in digesters fed with organic residues (slurry, manure, agricultural or agro-industrial waste). Biomethane production thus enables the valorization of waste to locally produce renewable energy while reducing greenhouse gas emissions associated with its treatment.<\/span>\u00a0<\/span><\/span><\/p>\n

The chemical composition of biomethane is identical to fossil natural gas, allowing it to be blended into existing distribution and transport networks. It can also be compressed and used as fuel in vehicles (bioCNG) or ships.<\/span>\u00a0<\/span><\/p>\n<\/div><\/div><\/div>\n\n

Measurable Reduction of Carbon Footprint <\/h2>

Combustion of biomethane, like natural gas, emits carbon dioxide (CO\u2082 ). However, the CO\u2082 \u00a0released from biomethane combustion is biogenic: it originates from the degradation of organic matter, not from fossil carbon extracted from deposits buried for millions of years. This is referred to as the \u201cshort carbon cycle,\u201d as opposed to the \u201clong cycle\u201d of fossil carbon.<\/span>\u00a0<\/span><\/p>\n

This\u00a0difference\u00a0is\u00a0reflected\u00a0in the\u00a0<\/strong><\/span>emission\u00a0factor<\/strong>, expressed in grams of CO\u2082 \u00a0equivalent per kWh. For biomethane injected into the grid and consumed for residential or commercial use in France, this factor is 23.4 g CO\u2082 -eq\/kWh LHV, compared with 216 g CO\u2082 -eq\/kWh LHV for fossil natural gas. Biomethane produced by WAGABOX\u00ae units in France has an emission factor of 16.52 g CO\u2082 -eq\/kWh LHV, a level comparable to renewable electricity sources.<\/span>\u00a0<\/span><\/span><\/p>\n<\/div><\/div><\/div>\n\n

Higher Production Cost Offset by the Green Value of Gas <\/h2>

Biomethane production costs are structurally higher than fossil natural gas. Investments required for waste collection and transport, biogas purification, and grid connection remain relatively high, whereas large-scale fossil gas extraction benefits from significant economies of scale.<\/span>\u00a0<\/span><\/p>\n

This additional cost is offset by the environmental and social value of biomethane: reducing greenhouse gas emissions, decarbonizing activities (transport, industry, heating, etc.), supporting local economies through the circular economy, and reducing dependence on fossil energy imports. That is why many countries support RNG production through subsidies or guaranteed purchase tariffs.<\/span>\u00a0<\/span><\/p>\n

By valorizing gas emitted from landfilled waste, the WAGABOX\u00ae technology can produce biomethane at competitive prices. At large landfill sites, this renewable gas can be sold under private purchase agreements (\u201cBiomethane Purchase Agreement\u201d), independently of any public support mechanism.<\/span>\u00a0<\/span><\/p>\n<\/div><\/div><\/div>\n\n

Certified Green Value <\/h2>

Various certification mechanisms allow buyers to recognize biomethane purchases in their environmental reporting and obtain regulatory or fiscal benefits.<\/p>\n

In Europe, Waga Energy\u2019s biomethane is ISCC-certified (International Sustainability and Carbon Certification), verifying compliance with sustainability and greenhouse gas reduction criteria defined in the EU RED II directive. This certification provides access to EU ETS quota exemptions or carbon tax reductions, depending on national regulations.<\/p>\n

In France,\u00a0Waga\u00a0Energy\u00a0was\u00a0the first\u00a0company\u00a0to issue\u00a0Biogas\u00a0Production Certificates (CPB),\u00a0certifying\u00a0the green value of the\u00a0gas\u00a0and\u00a0allowing\u00a0them\u00a0to\u00a0be\u00a0traded\u00a0independently\u00a0of the\u00a0molecule.<\/p>\n

In the United States, biomethane produced by Waga Energy qualifies under the federal Renewable Fuel Standard (RFS). Classified as a cellulosic biofuel, it generates credits usable to decarbonize transport activities.<\/p>\n

Waga Energy can commercialize biomethane with or without associated certificates, depending on the buyer\u2019s needs.<\/p>\n<\/div><\/div><\/div>\n\n

Advantages of Biomethane Produced at Landfill Sites <\/h2>

Biomethane obtained via the WAGABOX\u00ae process from landfill gas is chemically identical to biomethane produced by anaerobic digesters or wastewater treatment plants. Its methane content reaches 97%, providing a calorific value equivalent to high-calorific natural gas (\u201cH Gas\u201d). It also meets injection criteria for grid operators in most countries (CO2, oxygen, sulfur content, etc.). Where no gas network is nearby, it can be compressed and transported by road (\u201ctrucked gas\u201d).<\/span>\u00a0<\/span><\/p>\n

The WAGABOX\u00ae process also reliably and cost-effectively reduces fugitive methane emissions at landfill sites, which are potent contributors to global warming (methane\u2019s warming potential is up to 80 times higher than CO2). Due to the lack of a reliable measurement methodology, this impact is currently not included in the emissions savings reported by Waga Energy.<\/span>\u00a0<\/span><\/p>\n<\/div><\/div><\/div>\n<\/div>\n<\/div>\n<\/div>\n\n
