Gas capture at Alsdorf Warden landfill

Project period



AWA Entsorgung GmbH

Task and implementation

In the course of remediation and sealing measures, we were commissioned to expand the gas collection system in the area of plot 1 East at the Alsdorf Warden landfill site. This was to ensure the subsequent operation of waste management and energy facilities.

According to our plans, the gas from several wells will now be collected via manifolds, brought together in two substations and from there transported in suitable pipes to a combined heat and power plant. The condensate produced is collected in low-point areas in three shafts. In addition, energy lines for the control of pumps, data lines for the transmission of measured values and signals as well as cable conduits for later use were laid.
