Waga Energy commissions 60 GWh biomethane unit in Iowa

Waga Energy, specialised in upgrading landfill gas into grid-quality biomethane, has announced the commissioning of a biomethane production facility at the Scott Area Landfill site in Scott County, Iowa. The project was developed in partnership with the Scott County Waste Commission and Linwood Mining and Minerals, the site’s landowner.

Energy output equivalent to 6 million litres of diesel

The unit, equipped with the proprietary WAGABOX® technology, is designed to produce more than 60 gigawatt hours (GWh) of biomethane annually, equivalent to the energy content of 6 million litres of diesel. The biomethane is injected into the local natural gas grid and is intended for regional energy use. The installation will capture methane emitted from the decomposition of landfilled waste, reducing uncontrolled emissions from the site.

A project on a site processing 185,000 tonnes of waste annually

The Scott Area Landfill, operated by the Scott County Waste Commission, processes approximately 185,000 tonnes of waste annually from 17 local municipalities. The new facility converts landfill gas into commercial-grade biomethane, providing a new energy source while monetising a previously untapped resource. The land is leased from Linwood Mining and Minerals, a local industrial actor.

Cooperation between public and industrial stakeholders

The project reflects a joint effort between public institutions and private entities. The Scott County Waste Commission manages the site’s operations, Linwood Mining and Minerals provides the land, and Waga Energy is responsible for the design, construction and operation of the biomethane unit. According to the partners, this collaboration enables waste management to align with energy production in support of regional economic development.
