Saxlund selected for Hertfordshire gasification plant

The £60 million plant, which will be based in Hoddesdon, is a joint venture between Bouygues Energies & Services and specialised investment fund AssetGen Partners.
Hertfordshire County Council has approved plans for a controversial incinerator in Hoddesdon, which would be used for all of the county’s waste.

Development of a 96,000 tonnes-per-year capacity waste gasification plant in Hertfordshire is underway – with Saxlund International selected to construct fuel storage bunkers at the facility.

Construction of the facility has also been part-financed by the Green Investment Bank and its partner Foresight Group, which injected £30 million into the project in March 2015 shortly after it received planning permission

Capable of producing 10MW of power for the National Grid, the facility is the ‘largest’ proposed energy from waste plant in the UK to utilise the thermal treatment technology according to Bouygues, which will design, construct and operate the facility for a period of 10 years.

The facility is due to begin operations in early 2017 and will source feedstock from ‘local’ commercial and industrial waste businesses.

Saxlund, which is part of the Trention AB energy and environmental technology group, has been contracted to provide a ‘Push Floor’ fuel storage system for the facility, as well as discharge bunkers.

Bunkers

The company will install and commission two crane-fed fuel bunkers with shear walls constructed in steel, capable of handling the 96,000 tonnes of refuse-derived fuel (RDF) required for the plant each year. The bunkers will receive, store and discharge RDF to twin conveying streams feeding the gasifiers at the plant.

Gasification

Despite recent concerns surrounding the viability of gasification technology, Bouygues Energies & Services is connected to a number of thermal treatment projects in the UK.


Hoddesdon

Located 22 miles north of London, Hoddesdon has become an area linked to significant EfW growth in recent months – with Veolia also choosing the area to site its 380,000 tonnes-per-year capacity mass-burn incinerator. Due to handle all municipal residual waste in the region, the plant was accepted in principle by Hertfordshire county council in March this year
