Biffa have ditched plans for an energy from waste plant in favour of a soil recycling facility in Hertfordshire.
The firm had been preparing to submit a planning application for an incinerator at its Westmill site.
However the company is now planning a temporary soils repair centre instead.
It will be on the southwest part of the landfill site which has been quarried buy not yet landfilled and restored.
The facility will convert contaminated soils into re-useable clean soils which can then be used on site as restoration and daily waste cover, the company said in its proposals.
Biffa consulted residents about a proposed energy from waste centre in 2009 for 400,000 tonnes of waste a year.
However the project was put on hold and Biffa said that it hoped the new proposal will be more acceptable to local residents.
Biffa said that there would be no impact on traffic as the amount of soil transported to site would remain the same. It added that there would be no additional impact to noise or smells at the site as a result of the new facility.
A planning application is due to be submitted to Hertfordshire County Council in the next few weeks. Biffa will also apply for an Environmental Permit from the Environment Agency.
