The Solid Waste Association of North America (SWANA) is hosting a virtual summit in place of SOAR this June 17th. The Landfill Challenges Summit presents sessions from 12:00 – 5:00 pm EDT and on-demand sessions throughout the conference.
The Landfill Challenges Summit brings together landfill, landfill gas, and biogas professionals throughout the United States and Canada. Industry experts, including those at SCS Engineers, will discuss current and future challenges that are expected to impact landfill operations and landfill gas production and what lessons can be applied as we move forward.
As vacant land becomes more scarce, developers are turning to former landfills, which are often large tracts in prime locations, are now use. Daniel Cooper and Somshekhar Kundral use examples demonstrating how landfills and lakefills may be reclaimed, allowing the community to realize economic benefits in previously unusable areas for development while improving environmental protection. However, redevelopment on such site poses several environmental and geotechnical challenges. The design concepts of methane gas management systems vary based on the site’s subsurface conditions, building footprint, and the perceived risk tolerance of building owners. Several gas management barriers are available in the market today and can be broadly classified into the asphaltic spray-applied liner and the HDPE liner. The use of these liner systems depends on subsurface conditions and the size of the building. SWANA CEU: .50
