BIOMETHANE FOR ALL

Landfill gas recovery and upgrading to grid-quality biomethane

Waga Energy has developed a breakthrough technology to recover landfill gas into biomethane, also called Renewable Natural Gas (RNG).

The WAGABOX^® is a landfill gas upgrading unit that delivers high-quality biomethane, regardless of the quality of the raw biogas. The biomethane produced by the WAGABOX^® can be injected directly into the gas grid or used as fuel for vehicles.

Waga Energy builds, owns, operates, and maintains the WAGABOX^® units under long-term contracts with landfill owners in which biomethane sales revenue is shared.

Upgrading landfill gas — a waste-management by-product — positions Waga Energy to provide the most competitively priced biomethane on the market for end customers. A large-capacity landfill can provide consumers a biomethane with similar prices to that of the fossil-based gas.

WAGABOX^® units have a double impact to help fight climate change: they capture landfills gas — a major source of greenhouse gas emissions — and produce a renewable substitute for fossil-based natural gas.

Each new WAGABOX^® unit marks additional progress toward a true energy transition and toward protecting our environment.

Landfills: a source of renewable gas to be harnessed

Human activities produce more than three billion tons of waste per year. Most of this waste is landfilled (31% of waste in France).

The decomposition of the organic matter trapped underground with the waste will spontaneously release a biogas in which methane is the main compound.

Methane (CH₄), an appealing source of energy, is the main component in natural gas, a fossil-based gas widely used for heating and transportation. However, before this gas can be injected into utility grids, it must be purified.

Waga Energy has developed a simple, economical solution for upgrading landfill gas into grid-quality biomethane. This solution makes it possible to harness an abundant source of renewable gas: landfills.

According to the ADEME, the French Agency for Environment and Energy Management, by 2023, French landfills could possibly produce up to 8,189,140 mmBtu (2.4 TWh) of biomethane per year — enough to supply a city the size of Lyon with gas.
