Construction wastes have become the major source of solid wastes in Hong Kong. Thousands of tonnes of solid wastes are produced every year from construction and demolition activities. Increasing generation of these wastes has caused significant impacts on the environment and aroused growing public concerns. Therefore, the minimization of construction wastes has become a pressing issue. This pap...

Metals, including rare earth elements (REE), are the cornerstone of our current and future low-carbon urban infrastructure. This study looks at different waste resources contaminated materials present in setting as REE sources. Wastes other dilute sources such incineration ashes, sediments, mine tailings not only essential achieving a circular, carbon-neutral economy but may be most realistic o...
