Abstract:
Landfill gas often containing 50-60% methane, is generated on waste disposal sites receiving organic waste. Regulation requires that this gas is managed in order to reduce emissions, but very few suggestions exist as to how management activities are monitored, what should be set up to ensure this management and how criteria should be developed for when monitoring activities are terminated. Methane emission monitoring procedures are suggested, based on a robust method for measuring total leakage from the site; additionally, quantitative measures, to determine the efficiency of the performed emission mitigation, are defined. The tracer gas dispersion measuring technique is suggested as the core emission measurement methodology in monitoring plans for methane emissions from landfills and a guideline for best practice measurement performance is presented. A minimum methane mitigation efficiency of 80% is suggested. Finally, several principles are presented on how criteria can be developed for when a monitoring program can be terminated. Three of the suggested principles result in comparable completion criteria of about 1-3 kg CH4/h for a small landfill (an area of 4 ha).
摘要:
填埋气体通常含有50-60%的甲烷,是在接收有机废物的废物处置场产生的。法规要求对这种气体进行管理,以减少排放,但是关于如何监控管理活动的建议很少,应该设置什么来确保这种管理,以及如何为监测活动终止时制定标准。建议使用甲烷排放监测程序,基于测量现场总泄漏量的稳健方法;此外,定量措施,为了确定所执行的排放缓解的效率,已定义。建议将示踪气体扩散测量技术作为监测垃圾填埋场甲烷排放计划的核心排放测量方法,并提出了最佳实践测量性能的指南。建议最低甲烷缓解效率为80%。最后,关于如何为何时可以终止监控程序制定标准,提出了一些原则。建议的三个原则导致小型垃圾填埋场(面积为4公顷)的完成标准约为1-3kgCH4/h。
