Waga Energy earns certification for landfill gas system

France-based landfill gas (LFG) to renewable natural gas (RNG) technology provider Waga Energy has earned International Sustainability & Carbon Certification (ISCC) EU certification for a facility it has under construction at the PreZero landfill site in Els Hostalets de Pierola, Spain.

The firm says it also is seeking ISCC status for several additional facilities that are either under construction or operational.

The facility being built at the landfill site near Barcelona in the Catalonia region is its first to be awarded ISCC EU accreditation, which Waga Energy says helps boost the market value of RNG. The landfill is owned by Germany-based PreZero as a result of its 2021 acquisition of waste and recycling assets formerly owned by Spain-based Cespa S.A.

The ISCC EU certification was awarded following an independent audit conducted in April. “This accreditation proves that the installation meets sustainability and greenhouse gas (GHG) emissions savings criteria set out in the European RED II Directive,” the firm says.

“ISCC certification guarantees that the RNG we produce is traceable and compliant with European biofuel regulations, which helps boost its value,” says Lucie Tonnellier, energy director at Waga Energy. “This will enable us to increase the selling price of RNG produced by our first Spanish facility.”

Waga Energy says it has begun the certification process for all its European facilities with production capacity of at least 20 gigawatt hours (GWh) per year. In France, ISCC certification soon will be a requirement for accessing the feed-in tariff.

Though based in Europe and most active there, Waga Energy has active installations in Canada and has indicated it also views the United States as a potential growth market for its landfill gas-to-energy technology.
