垃圾填埋场排放的甲烷是英国乃至全世界温室气体的重要来源。这篇论文考虑了甲烷排放的测量如何被用来规范英格兰的垃圾填埋场，以减少垃圾填埋场对气候变化的贡献。这篇论文介绍了英国为量化垃圾填埋场甲烷排放而进行的一系列研究的结果。使用的方法包括DIAL（差分吸收激光雷达）技术和示踪气体分散方法。开发了一种基于航空测量的方法。测量了15个可生物降解垃圾填埋场的甲烷排放率。所有进行测量的垃圾填埋场都有一个活跃的垃圾填埋气体提取系统。利用甲烷收集率与收集率和排放率之和的比率，计算每个填埋场的甲烷收集指数（MCI）。在这里报告的活动中，该指数的值从0.28到0.90不等。受调查的现代营运堆填区的MCI值范围较窄，介于0.64至0.90之间，平均值为0.76。这表明，这些垃圾填埋场可以收集大量的垃圾填埋气体。提出了一种利用测量的MCI来调节垃圾填埋场的方法。这将涉及每年进行一次测量活动，以量化甲烷排放量，并利用这些调查提供的数据制定一个可实现但具有挑战性的MCI限制。MCI的极限值为0.75，用于说明该方法。MCI低于上限将触发减少垃圾填埋场甲烷排放的行动。
Methane emissions from landfills are an important source of greenhouse gases in the UK and worldwide. This paper considers how measurements of methane emissions could be used to regulate landfills in England in order to reduce the contribution of landfilling to climate change. The paper presents the results of a number of UK studies undertaken to quantify methane emissions from landfills. The methods used have included the DIAL (Differential Absorption Lidar) technique and a tracer gas dispersion method. A method based on aerial measurements has been developed. Methane emission rates were measured at 15 biodegradable waste landfills. All of the landfills where measurements took place had an active landfill gas extraction system. A methane collection index (MCI) is calculated for each landfill using the ratio of the methane collection rate to the sum of the collection and emission rates. The values of the index in the campaigns reported here ranged from 0.28 to 0.90. The modern operational landfills surveyed achieved MCI values with a much narrower range of between 0.64 and 0.90 with an average of 0.76. This has demonstrated that it is possible for these landfills to collect a high proportion of the landfill gas. A proposed approach is presented for regulating landfills using the measured MCI. This would involve an annual measurement campaign to quantify the methane emissions and the use of the data provided by these surveys to develop an achievable but challenging MCI limit. A limit value of 0.75 for the MCI is used to illustrate the approach. An MCI that falls below the limit would trigger actions to reduce the methane emissions from the landfill.
