Landfill Subsurface Exothermic Events
This short course will review research and experience from case histories related to subsurface heat generation and accumulation at landfills.
The course emphasizes contributing factors to Elevated Temperature Landfills (ETLFs) such as biological-chemical processes, operational practices and environmental conditions that have been experienced at several ETLFs.
There will be a very brief discussion on the modeling of ETLFs and the possible mechanisms that trigger such reactions within landfills. These models have many assumption in regards to waste composition and environmental factors affecting. Regardless, we will forge ahead and report on findings that predict heat generation, consumption and releases from ELTFs.
A large portion of the course will deal with the management of ELTFs. We will first discuss monitor temperature and other landfill constituent properties (gas and leachate composition and quality) to try and predict various phases during an ELTFs life.
We will then take these properties and see how they might affect slope instability, settlement and releases at the landfill.
Finally, we will try and address how to minimize damage to infrastructure and containment systems at the landfill. Such mitigating efforts will hopefully have the effect of isolating and containing heat within the ELTF and reducing risk to human health and the environment.
