Pyrolysis plant given green light

Planning permission has been given for an 18,000-tonne pyrolysis plant at Seamer Carr in North Yorkshire.

Scarborough Power received planning permission for the facility, which is part of the new technologies demonstrator programme run by the Environment Department (DEFRA), on 24 April.

Scarborough Power is a partnership between Yorwaste, pyrolysis company GEM and engineering consultancy NEL Power.

The plant will be built at Yorwaste’s landfill site and will process 18,000 tonnes of residual household waste from Scarborough each year. This will undergo ‘flash pyrolysis’ - heating in the absence of air - to convert it into syngas, which in turn will be used to produce 2 megawatts of electricity for the grid.

It will also produce 2.5MW of heat that will be supplied to a local industrial estate via a district heating network.

Apart from exhaust gases, the only residue from the system will be a non-hazardous carbon char, which will be sent to the landfill.

The company has applied to the Environment Agency for a pollution prevention and control permit and expects a decision in July. If received, it intends to build the plant by early 2008.

The plant is one of two pyrolysis facilities being built under the new technologies programme. Compact Power intends to have its 30,000-tonne pyrolysis and gasification facility in Bristol running by the autumn (ENDS Report 375, p 21 ).
