EREF Summit: Emerging Topics in Landfill Management, Columbus, Ohio

Wednesday, September 2021

Register Here for EREF’s Emerging Topics in Landfill Management Summit

Join EREF, Ohio EPA, and industry leaders who will cover emerging topics in landfill management with a focus on:

• Why waste slides occur – the primary factors attributed to instability
• Elevated temperature landfills and how they affect waste mass instability
• State of practice of aqueous waste disposal in landfills
• Liquids addition and leachate recirculation

The Summit will take place at the Marriott Columbus University Area in Columbus, Ohio. Rooms are $119 per night.
As with many EREF events, this will likely fill to capacity quickly.
