Thermally-driven ammonia stripping was developed by Organics to offer an alternative route to that of pH adjustment for continuous-process ammonia stripping. With a thermally-driven stripper no chemical additions are required. I've started this blog post to gauge the interest within SWANA. If it is of interest, we'll put together a multi-part series of posts covering ammonia removal, recovery and re-use options. The single important input for the thermal ammonia removal system is waste-heat with which to drive the chemical reactions. If waste-heat is not available, the fuel-cost can be as prohibitive as that of chemical additions or carbon source requirements. ...

In Wisconsin, current code requires landfill operators to install final cap within two years after an area of the landfill has reached final waste grades. We have seen this lead to decreased gas production and presumably extended organic stability timeframes at several landfills statewide. Also, we have seen sites with substantial settlement within the first 5-7 years that are unable to refill the settlement airspace because it was capped within 2 years. As a result, we are doing some research into the state of the industry regarding permeable caps and/or delayed capping schedules. What are the capping requirements in other parts of North America? ...

Can landfills plan for a great legacy and actually begin working on that legacy today? Landfill site master plans and end-use plans that sit on the shelf for some future day don’t have a lot of credibility with the neighbors or host community. Sure landfill owners need flexibility and change happens but… read this succinct linked article http://americancityandcounty.com/blog/viewpoint-creating-great-landfill-legacy
