Olivine-treated marine clay: An innovative CO2 sequestering landfill base liner material

This research investigates the development of an innovative landfill base liner material utilizing olivine-treated marine clay. The innovative refers to its ability to sequestrate any excess CO2 emission in the landfill which may then be used for its strength and hydraulic conductivity improvement. This study reveals that olivine-admixed marine clay can be used as an innovative base liner material in engineered landfills with the potential of sequestering landfill CO2 while also enhancing the hydraulic conductivity and strength of the liner material. Insights from this work are crucial towards achieving long-term sustainability in liner management.
