The Rookery South Pit site is 95 hectares and the ERF will occupy approximately 10 hectares of the total area.
Covanta considered a range of design options through studying a building code established in conjunction with the Commission for the Built Environment (CABE), English Heritage, Central Bedfordshire and Bedford Borough Councils.
The ERF location and orientation is designed to keep the visual impact on the surrounding area to a minimum and to also reduce potential noise.
The building design of 'interlocking boxes' was selected as it allows the height of the building to be reduced and addresses the dominance of the roof profile in medium and long distance views.
The height of the ERF is also at the lower end of the range when compared with other UK EfW plants.
