For 2020 Deba Bailarako Industrialdea, S.A. commissioned Afvalzorg the contract to continue landfill gas management in Elgoibar, Spain. The past years Afvalzorg already considered solution options and managed a landfill gas extraction system.
The closed landfill site Urruzuno in Elgoibar is a special location. On top of this former landfill, an industrial business area has been constructed while no impermeable top cover system was installed at the site. This has led to very risky situations in the past due to the accumulation of landfill gas underneath the business premises. As a result of a landfill gas related fire in one of the business premises, Afvalzorg mapped out the situation in 2013, considered solution options and ultimately designed and managed a landfill gas extraction system.
Through installation of the landfill gas extraction system, plus some additional measures, the risks related to landfill gas migration and accumulation have been significantly reduced and CH4 levels beneath the floors of the buildings reduced from 45% to less than 10 ppm. Of course, this extraction system requires meticulous management. As in previous years, we have been proudly awarded the contract for management and maintenance of the system in 2020 to provide for a safe situation for all companies situated at the Urruzuno landfill.
