What we did

Investor, designer and operator of the first unit in a pipeline of containerised digesters.

Scope

REURASIA finances, designs and will operate the plant. Alterna Verde owns and runs the recovery and recycling facility that hosts it. atmosfair provides the low-interest debt and the carbon-finance path under the Gold Standard for the Global Goals.

Where it stands

Fabrication of the digester modules, the technical and pumping containers, the flare and the gas circuit is complete. The units are being prepared for shipment to the site. This is a planned project; results on waste diversion, electricity generation, fertiliser quality and methane control will be published once the plant is commissioned and independently verified.

Sector: Private landfills and waste operators. All references: the reference list.
