    • Life cycle assessment on construction and demolition waste recycling: a systematic review analyzing three important quality aspects
    Authors: Bayram, Berfin; Greiff, Kathrin;  Advisor: -;  Co-Author: - (2023)

    Life cycle assessment (LCA) is increasingly being applied to construction and demolition waste (CDW) recycling. But what is the current state of LCA studies on CDW recycling? In the context of circular economy, several aspects become important in LCA, such as avoided impacts and consideration of the quality of recycled materials. The aim of this study is to identify inconsistencies and best practices, and then provide recommendations for future LCA studies focusing on CDW recycling.
    • Construction and demolition waste repurposed for heavy metal ion removal from wastewater: a review of current approaches
    Authors: Ranaweera, K. H.; Grainger, M. N. C.; French, A. D.;  Advisor: -;  Co-Author: - (2023)

    Over the past few decades, the world is facing critical water supply problems caused by the relentless increase of global human populations and the associated rise of anthropogenic activities. Heavy metals are among the main water pollutants which pose a great threat to human health. Hence, globally there has been a large amount of research devoted to investigating cost-effective and sustainable methods for removal of heavy metals from polluted water. One such area of interest is the utilization of construction and demolition waste (CDW) materials for the adsorptive removal of heavy metal ions (As, Cd, Co, Cr, Cu, Hg, Ni, Pb, Sr, and Zn). This review focuses on the most current research for the use of CDW as an adsorbent. The different heavy metal ion removal mechanisms involved are...
