Biffa Soil Treatment

The European Landfill Directive has created a new market for the road haulage industry. Until the UK implemented this Directive in 2004, most contaminated soil designated as hazardous waste was simply dumped into landfill sites. The treatment of this waste has become more difficult and more expensive because it now has to be treated before going to landfill.
In addition, the number of landfill sites able to accept hazardous waste has fallen dramatically from more than 300 to fewer than 10, which means it generally has to be moved further creating work for specialist hauliers.
To cater for this market Biffa has teamed up with Biogenie Site Remediation, whose core business is the remecfiation of contaminated soil and groundwater. Together they offer companies a means of removing contaminated soil from sites and avoiding the need to dump it in a landfill site was the main aim of the Landfill Directive.
Biffa and Biogenie run the Soil Treatment Clinic at Risley, near Warrington. Cheshire. which as the UK's first fixed soil remediation service, can recycle contaminated soil. The demand is certainly thereabout a million tonnes are produced in Britain every year, and disposal is a serious problem for developers.
Biffa general manager John Conway explains: "These soils must be removed from a site before developers can begin work. If landfill is not an option, the only alternative has been to treat them on site, yet they can hinder operations.
But we can accept soils for treatment away from site, releasing an area for immediate development and that saves developers time and money.'
Landfill is still widely recognised as the primary method of waste disposal for many types waste types.
Cleaning up contaminated soil from the redevelopment of brownfield sites and taking it to landfill is the quickest method of removing such contamination. Biffa offers 'disposal only and comprehensive 'haulage and disposal' options to developers and contractors.
Sites are operated under strict regulations that control the types and quantities of the individual contaminants that comprise each load.
