About The Landfill

The Clayton Hall site has been used as a landfill since the 1960s.  Over this time the site has developed in line with advancements in landfill engineering and pollution control management and now also includes the extraction of landfill gas and the treatment of leachate.  The site has a permit to operate until 2028 at which point the landfill will be capped and restored in line with the approved planning consent.  However, aftercare of the site will remain in place until 2088.

We ensure that our site does not have any environmental impact and we regularly liaise with regulatory authorities as well as holding regular meetings with members of the local authorities and community to answer any questions that they may have.

Landfill gas is a natural bi product of the decomposition of organic materials in landfills such as paper, wood, food stuffs, etc and comprises of approximately 40-60% methane with the remainder being mostly carbon dioxide and these gases are a major source of renewable energy.  As a result of this, and the fact that Quercia is committed to sustainability, in 2009 a landfill gas power generation plant was constructed to capture the gas produced.  The plant comprises of two spark ignition engines with an output of 1.5 MWe (which can power up to 1000 properties) and gas is extracted from the site using vertical extraction wells working 24 hours a day, seven days a week.  Once captured the gas is burnt and converted into electricity and fed into the national grid.

In 2010 a biological leachate treatment plant was constructed.  The treatment plant receives the leachate (contaminated liquid generated within the landfill site) and uses bacteria to reduce the level of contaminants in the liquid before it is discharged to the sewer.
