Description of the project:
The Euskirchen district has been operating a composting plant for biowaste from separated household collection as well as for private, municipal and commercial green waste at the former Mechernich landfill site since the mid-90s.
In 2001, the composting process was converted from open box composting to tunnel composting, consisting of 10 decomposition tunnels designed for a throughput of 26,600 t/a. The conversion also included the renovation of the structure and the reorganisation of the operational processes in order to optimise the emissions situation as well as replanning the hall ventilation.
In 2005, the Euskirchen district decided to extend the composting plant by 5 decomposition tunnels to optimise the operation. The 5 new decomposition tunnels were integrated into the plant by extending the existing intensive decomposition hall.
The extension of the decomposition technology had to be performed under the following conditions:
As individual processing technology modules in the composting plant had also reached the end of their useful lives, the processing technology in the existing delivery and processing hall was converted using mobile processing technology.
As a result of the limited space available at the location, a stacking basin in the vicinity, in which leachate from the landfill area is temporarily stored, had to be converted prior to implementing the extension measures for the composting plant.
All of these measures were implemented by calling for tenders for the following lots:
All services were provided for the construction (civil engineering, infrastructure) and process technology.
Initial construction measures:
Initial construction measures 1999 - 2001
Extension 2005 - 2006
