Field scale evaluation of innovations in landfill engineering

垃圾填埋场在关闭后的几十年甚至几个世纪内仍会继续产生甲烷和渗滤液，特别是在半干旱气候地区，如加拿大大草原。快速稳定旧的市政垃圾填埋场将使市政当局能够降低长期成本，避免未来潜在的环境问题。快速稳定确实带来了与废物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，目的是将填埋工程的土工方面与与废物和渗滤液生物稳定有关的土工方面以及与堵塞过滤器和排水系统有关的生物地球化学过程结合起来。探索基金将为整体工作的特定方面提供资源，这些方面代表了这些技术的长期发展和应用的重要技术/科学挑战，但这些不是市政业主资助的当务之急。考虑到伦敦金融城将支付所有的钻孔、井下仪器和气井等费用，探索基金将战略性地使用，以产生最大的效益。

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.
