Landfill gas detection 2018-2022 at Austrian mass waste dumps.

The present study looked at the collection and treatment of landfill gas in 48 mass waste dumps over the 2018-2022 investigation period. Subsequently, the time series previously conducted from 1990 to 2017 was extended to 2022. In addition to the amounts of landfill gas collected and treated, information was also collected on the measures taken by the landfill operators to increase landfill gas collection, as well as the extent of temporary surface covers, irrigation measures and precautions to reduce residual emissions. In the context of the conclusion, a summary of the main results and a brief outlook on the future development of the recorded landfill gas volumes and the measures to be taken by the operators in the handling of the remaining landfill gas are provided.本研究针对2018-2022年调研周期内的48座大型垃圾填埋场的填埋气（Landfill Gas）收集与处理情况展开调研，并将此前1990-2017年已有的时间序列（Time Series）数据延伸至2022年。 除填埋气收集与处理体量相关数据外，本研究还采集了垃圾填埋场运营方为提升填埋气收集效率所采取的各类措施，以及临时表层覆盖范围、灌溉措施和降低剩余排放的防护举措等相关信息。 在结论部分，本研究对主要研究结果进行了总结，并针对记录的填埋气体量的未来发展趋势，以及运营方在处置剩余填埋气时应采取的措施给出了简要展望。
