Imtech wins £14.5m contract to build Herts AD plant

Anaerobic digestion (AD) company Tamar Energy has awarded a £14.5m contract to Imtech Water, Waste and Energy (Imtech) to build a 3MW AD facility in Hertfordshire.

The Hoddesdon plant will process 66,000 tonnes of unavoidable food waste a year. Electricity produced will be enough to power 6,000 homes.

The plant will also produce 18,000 tonnes of digestate.

There is also a biological wastewater treatment plant to recycle process water.

Bruno Speed, Imtech managing director said:  “We are also working with Tamar Energy on a number of other projects.

“Each site will have different constraints, but we relish the opportunity to work with Tamar to provide the best possible AD solution for each individual project.”

Tony Wilson, director of construction and operations at Tamar Energy, said: “Imtech has significant expertise in delivering complex projects in a cost-effective and innovative way.

“The ex-power station site is exceptionally complex, with numerous challenges, including a flood plain location, ecological considerations, high pressure gas main through the centre of the site, adjacent 400kVa high voltage overhead power lines, in ground power lines and an adjacent historic asbestos landfill.”

This month Tamar Energy’s new chief executive Willie Heller told MRW that his company was entering “high growth mode”.

WRAP support for AD

WRAP are now offering support for AD operators looking to develop secure markets or outlets for their digestate.

Up to five days of one-to-one support is available on getting started, or for those who have already made some progress.

The aim is to ensure operators learn the benefits of effective digestate management and planning.
