Basics of Landfill Aeration

11 Marzo 2021
Waste management

Landfills are a source of significant emissions in terms of polluted leachate and greenhouse gases which mainly occur under conventional operating conditions (i.e., anaerobic conditions). When considering the specific type and quality, and quite often lack of, barriers, these leachate and gas emissions may result in a significant negative impact on the environment.

Landfill aeration represents one part in a sequence of measures, starting with waste deposition and ending with the termination of aftercare. Aeration effectively stimulates processes, which are capable to transfer a landfill from the post-closure phase, where gas utilization is no longer profitable and/or feasible, to a long term phase where active provisions for emission control are no longer needed. At that time, the final top cover can be installed and a basis for multiple options of landfill after use has been established.

The webinar “Basics of Landfill Aeration” contains information on the background of the methodology, results from both field and lab scale tests and a number of examples of field scale projects in several countries. Specific technological aspects such as off-gas treatment and air injection devices will be discussed in more detail. The webinar concludes with considerations on associated costs and cost-saving-potentials as well as a summary on current programs, supporting landfill aeration projects.
