A consultation has been opened into an environmental permit for Yorkshire-based Gascorp Plaxton planned biogas plant.
The consultation was opened yesterday by the Environment Agency and runs until 12 December.
According to the consultation documents, the plant is planned for land in Beverley.
The documents reveal the plant will produce biomethane for export to the gas grid, although do not state how much will be produced.
It is also confirmed that the plant will process up to 80,000 tonnes a year of potato pulp and whole potatoes from a nearby food processing factory.
The potato pulp is produced in the factory and pumped by a centrifuge through sealed pipelines directly to the pre-tank, which is located within an enclosed, purpose-built, pasteurisation building.
The documents state "it is also possible" to use the same network of sealed pipes, to pump feedstock directly to the biogas plant’s digesters.
Whole potatoes that are unsuitable for food production are stored in the factory and fed "three to four" times per day into the existing hopper where they are macerated and then pumped into the pre-tank or digesters.
Biogas will be collected in fermenter and post-fermenter tanks and is stored in an integral inflatable gas holder, according to the documents.
The biogas is then upgraded to biomethane and injected into the gas supply system, owned by Northern Gas Networks.
Heat and power for the site are provided by a gas CHP engine rated at 550kWe output, which is fuelled either by biogas from the digesters or by the natural gas grid.
