Assessment of the Carbon Footprint of Green Concrete Liners in Landfill Construction—A Critical Review

This paper presents a critical review of the existing research on the assessment of the carbon footprint of green concrete liners used in landfill construction. The review assesses the current understanding of the carbon footprint of green concrete liners and the key factors that affect the carbon footprint, including the materials and production processes used to manufacture these liners. The review is based on a systematic literature search, which identified and reviewed a total of 28 papers. The papers included studies that examined the carbon footprint of green concrete liners from the cradle-to-gate stage and from the cradle-to-grave stage. The review also identified potential areas for further research in order to improve the current understanding of the carbon footprint of green concrete liners. The results from the review indicate that the carbon footprint of green concrete liners depends on the materials used, their production process, and their service life. Furthermore, the review revealed that the current research on the carbon footprint of green concrete liners is limited, and further research focusing on the service life and the end-of-life stage of these liners is needed in order to develop a robust assessment of the carbon footprint of green concrete liners.
