UK’s first BioSNG plant to use Saxlund technology

Currently under construction at Marston Gate in Swindon by Advanced Plasma Power and Cadent, the UK’s first commercial bio-substitute natural gas plant will use a fully automated fuel reception and delivery solution from Saxlund International.

The £25 million facility, due to commence operations in early 2018, will be capable of turning 10,000 tonnes household waste per annum into 22 GWh of synthetic natural gas (BioSNG), enough to heat 1,500 homes or fuel 75 heavy goods vehicles each year.

Waste will be delivered to the facility once a day with a moving floor trailer, and up to 150m3 will be stored to provide a buffer for weekend operation.

Saxlund, a biomass and material handling specialist, has been chosen to provide a complete automated solution incorporating fuel reception, storage and discharge of RDF to feed the downstream fluid bed gasifier which in turn is closely coupled to a plasma converter.

The chosen solution incorporates Saxlund Truck Docking Stations (SAX-TDS) designed to allow walking floor trailers arriving at the plant to be quickly unloaded, alongside a Push Floor storage bunker with 100m3 capacity and chain conveyors to transport fuel on to the gasifier.

“Producing 80 per cent lower carbon emissions than fossil gas, BioSNG is recognised as being key to decarbonising heat and transport in the UK and internationally. We are delighted to be involved with this pioneering project at Marston Gate,” said Matt Drew, managing director for Saxlund International.

“Like all of the bioenergy and gasification plants we are currently involved with, fuel handling and storage are critical areas to get right to ensure plant efficiency and peak productivity.”
