Construction and demolition waste (CDW) is one of the largest contributors to global waste
streams, simultaneously posing significant environmental and resource management challenges. The
management of CDW, particularly its potential for energy recovery and industrial symbiosis, has
garnered increasing attention as part of a circular economy approach. This comprehensive review
explores global practices in CDW management, analysing theoretical developments, technological
advancements, and emerging resource recovery and reuse trends. Background: CDW accounts for
more than a third of all waste generated in the EU. A wide variety of materials, such as concrete,
bricks, wood, glass, metals, and plastics, make it a very un-homogenous waste stream with high
potential for material recovery through different approaches. Methods: This review draws on an
extensive analysis of scientific literature, case studies, and industry reports to assess current practices
in the CDW stream and assessment of the feasibility of energy recovery, industrial symbiosis, and
object reconstruction. Results: The originality of the current research is based on a Latvian case study
on CDW management that provides valuable insights into household-level practices and progress
towards relevant UN SDGs. Conclusions: Various CDW streams have an undeniable potential for
valorization through various approaches. Currently, the most common approach is recovery and
recycling, although CDW has the potential to broaden its application within the circular economy
framework. For instance, industrial symbiosis is a solution that can not only boost the valorization of
CDW but also significantly increase material circularity.
