Landfill gas leakages in geosynthetic lining systems: closing missing gaps

点击翻译按钮获取中文摘要

This project aims to resolve the shortfall in the fundamental understanding of the coupling between gas flow and geosynthetic liner systems by developing practical and new modelling techniques. The project expects to underpin the development of an experimentally validated theory to predict gas leakage rates through geosynthetics composite liner systems. Expected outcomes of the project are the establishment of a new conceptual framework and improved integrated design tools for the mitigation of gas escape through geosynthetics liner systems. These outcomes are expected to benefit the waste industry by providing the necessary scientific advances to enable a better estimate of gas emissions from landfills.
