Field scale evaluation of innovations in landfill engineering

在关闭后的几十年甚至几个世纪里，垃圾填埋场可以继续产生甲烷和渗滤液，特别是在加拿大草原这样的半干旱气候地区。对旧的城市垃圾填埋场进行快速稳定将使市政当局能够降低长期成本，并避免未来潜在的环境问题。快速稳定确实带来了与垃圾中的水分和气体运动、排水系统堵塞和垃圾填埋场稳定性相关的挑战。简而言之，其目的将是将垃圾工程的岩土工程方面与垃圾和渗滤液生物稳定相关的方面结合起来。以及与过滤器和排水系统堵塞有关的生物地球化学过程。发现赠款基金将为总体工作的特定方面提供资源，这些方面对这些技术的长期开发和应用提出了重要的技术/科学挑战，但并不代表市政业主当前的优先事项。发现赠款资金将被战略性地用于产生最大的收益，因为市政府将支付所有的钻孔和井下仪器和气井等。

Landfills can continue to produce methane and leachate for decades or even centuries after closure, particular in semi-arid climates such as the Canadian Prairies.  Rapid stabilization of old municipal landfill sites will enable municipalities to reduce long term costs and avoid potential environmental problems in the future.  Rapid stabilization does present challenges associated with moisture and gas movement in the waste, clogging of drainage systems and landfill stability.   In short, the intent will be to bring together the geotechnical aspects of landfill engineering with those relating to waste and leachate biostabilization, and the biogeochemical processes related to clogging of filters and drainage systems.  Discovery Grant funds will provide resources for specific aspects of the overall effort that represent important technical/scientific challenges for long-term development and application of these technologies, but which do not represent immediate priorities for funding by the municipal owners.  Discovery Grant funds will be used strategically to generate the biggest bang for the buck, given that the City will have paid for all of the boreholes and downhole instrumentation and gas wells etc etc.
