ABSTRACT
Improper waste disposal and management due to industrial activity may lead to soil and groundwater contamination. Thus, the development of methodologies for mitigating waste generation and its valorisation should be investigated to reduce environmental impacts, create waste-based products, and fulfil sustainable development goals. When malfunctioning, earthworks can negatively impact the environmental, besides clayey soils have mechanical issues, and represent high costs of logistics depending on the region, in addition to geosynthetics being still a costly solution. Therefore, recent investigations are using industrials by-products for construction purpose. This research reviews the literature of the main wastes used as liner materials, and their laboratorial tests program to evaluate their potential for liner. Furthermore, a flowchart was designed to optimize the valorisation process depending on the waste availability, and a table developed within the tests over the literature available.
