Learn more about RNG

Maximum energy efficiency

Converting biogas captured at landfills (landfill gas) into RNG offers an energy yield that is 2-3x greater than solutions that involve converting biogas into electricity and heat.

Significant reduction in greenhouse gas emissions

Renewable natural gas is injected directly into existing natural gas distribution infrastructure, replacing fossil fuels, and reducing greenhouse gas (GHG) emissions by up to 90%.

Used as a compressed natural gas (CNG), RNG derived from biogas produced by waste also helps reduce CO2 emissions by 80% compared with diesel, and cuts fine-particle emissions by 95% and nitrogen oxides (NOx) by 50% compared with gasoline or diesel.

Short, competitive energy distribution cycle

The production of RNG at a landfill site supports the circular economy. Consumption by residents and businesses produces organic waste that is collected and stored in landfills.

The organic matter in this waste decomposes and produces a mixture of gases known as biogas. Once recovered, the biogas is purified and converted into renewable natural gas before being redistributed to consumers via the existing gas infrastructure, or used locally as compressed natural gas (CNG).

RNG produced from biogas derived from landfills is the most competitive on the market.

A lever for energy sovereignty

RNG from landfill waste provides a local, renewable, and immediately available source of energy to accelerate decarbonization and a transition to cleaner energy. Our WAGABOX® projects promote local energy independence and a circular economy.

Maximize your energy generation and environmental performance.

Explanatory diagram of the different waste-to-energy processes. The first diagram shows open-air waste storage, which emits biogas into the atmosphere, a gas containing 50% methane. This storage method is dangerous for the environment and produces no energy. The second diagram shows storage in non-hazardous waste storage facilities, where the biogas is captured and flared. This method produces neither environmental nor energy performance. The third diagram shows storage in non-hazardous waste storage facilities, where the biogas is captured and transformed into electricity. This recovery method has limited environmental performance and an energy yield of 30%. The final diagram shows storage in non-hazardous waste landfills, where the biogas is captured and purified into biomethane using WAGABOX technology. This recovery method delivers optimum environmental performance and an energy yield of 90%. Explanatory diagram of the different waste-to-energy processes.

Developed and patented by Waga Energy, the revolutionary WAGABOX® technology makes it possible to convert landfill gas into renewable natural gas.

The WAGABOX® technology combines two cutting-edge systems for upgrading biogas derived from waste, ensuring that the RNG produced by our units meets the standards for injection into natural gas pipelines.

Explanatory illustration of the WAGABOX technology. Raw biogas is treated by membrane filtration to separate carbon dioxide from methane. Impurities and CO2 present in the gas are expelled from the circuit. The partially treated biogas then passes through the cryogenic separation module, which separates the methane from the air gases using nitrogen. The air gases are expelled from the circuit. The 98%-pure biomethane is then injected into the gas distribution network. Explanatory illustration of the WAGABOX technology.

The WAGABOX® technology creates new opportunities for landfill gas recovery that combine energy generation, environmental compliance, and economic benefits.

The WAGABOX® technology is already in use at multiple landfill sites around the world owned by local authorities and leading waste management companies.

Waga Energy makes a difference for waste management companies and local authorities

The WAGABOX® solution offers significant economic and environmental advantages to help landfill site operators transform their landfill gas from a liability to a resource.

Up to 100% of project costs covered

Waga Energy handles all financing and on-site activities, such as the feasibility studies to the connection to the gas distribution pipeline.

Generating a regular income

The RNG produced by a WAGABOX® unit is marketed under a long-term contract with an energy off-taker, providing reliable and additional revenue for the landfill operator.

Easy to deploy

The standardized WAGABOX® solution is compatible with landfills of various capacities, starting at 500 scfm of collected landfill gas.

Our teams typically deploy WAGABOX® units within 12-24 months from contract signing, with the timeline influenced by local permitting and gas interconnection construction requirements.

Energy generation and environmental compliance

The WAGABOX® technology is efficient, performing regardless of the quantity and quality of the landfill gas being treated.

This reduces the risk of unwanted emissions and odors, while maximizing revenue for landfill operators when compared to alternative upgrading solutions.

Guaranteed continuity of service

WAGABOX® units operate 24/7, are fully automated, and controlled remotely by expert technicians. Their performance is optimized every day through the collection of 300,000 data points transmitted by more than 200 sensors installed on the units. Predictive, preventive, and corrective maintenance processes are managed by specialized operators.

Local development

The WAGABOX® solution contributes to the development of a circular economy: RNG produced locally from household and industrial waste at the landfill site is injected into the natural gas pipelines to supply local homes and businesses. This provides local communities the opportunity to achieve energy independence, while reducing waste management costs and effectively combatting global warming.

The WAGABOX® solution: a collaborative, controlled, and secured process

1. Analysis of renewable natural gas production potential from the landfill


Waga Energy performs pre-project studies and technical, economic, and regulatory feasibility analyses prior to implementation to obtain required administrative permits for producing and commercializing RNG. All parameters are shared transparently with the site operator and incorporated into the agreement between Waga Energy and the landfill operator.

2. Construction and installation of the WAGABOX® unit


Waga Energy manages all phases of construction and installation of the WAGABOX® unit. Site specifications, RNG production potential, landfill gas specifications, and RNG offtakes are analyzed prior to construction. Once civil engineering work is completed, and the equipment has been delivered to the site, Waga Energy’s technicians assemble the WAGABOX® unit. Standardized components and processes produce a faster installation timeline. Waga Energy is supported by a solid network of industrial, commercial, and financial partners, and covers all investments required to install, operate, and maintain WAGABOX® units.

3. Connection to the gas collection system and natural gas pipelines


Waga Energy ensures the dual connection of the WAGABOX® units. Connection is established upstream to the landfill gas collection system installed at the landfill, and the downstream connection is then established at the injection point on the natural gas distribution network.

4. Operation and maintenance


Fully automated and remotely controlled, WAGABOX® units operate 24/7 with a proven availability to exceed a 95% uptime. Waga Energy operates and maintains these units with the support of expert technicians working remotely or on-site. Data collected from all WAGABOX® units enables us to continuously improve energy and environmental performance.

5. Renewable natural gas sales


The landfill site operator, whether private or public, can choose between two types of partnerships with Waga Energy:

① The biogas recovered at the landfill can be sold to Waga Energy at a fixed price under a long-term contract. Waga Energy is responsible for marketing the RNG produced by the WAGABOX® unit at the best tariff.

②Waga Energy provides a service to operate and maintain the WAGABOX® unit and partners with the site operator, who markets the RNG on their own behalf.
