Landfill gas represents an opportunity for electricity generation and carbon abatement: it need not be managed solely for environmental, health or safety risk reasons. However, our ability to predict gas collection and fugitive emissions from landfills capped with geosynthetics liners, in consideration of the myriad of factors that control these processes, is imperfect. Building on recent advances in unsaturated soil mechanics, this project aims to conduct cutting-edge experimental and theoretical research to develop an experimentally-validated theory of gas migration through geosynthetics systems that is expected to lead to major improvement in performance and provide integrated design tools which are much needed but not currently available

填埋气是发电和减少碳排放的一个机会：不必仅仅出于环境、健康或安全风险的原因对其进行管理。然而，考虑到控制这些过程的无数因素，我们预测填埋场覆盖土工合成材料衬垫的气体收集和逃逸性排放的能力是不完善的。基于非饱和土力学的最新进展，本项目旨在进行前沿的实验和理论研究，以开发一种经过实验验证的土工合成材料系统气体迁移理论，该理论有望导致性能的重大改进，并提供急需但目前尚不具备的综合设计工具
