This article presents a comparative analysis of the circularity and cost-efficiency two distinct construction material recycling processes: ML-based automated sorting (MLAS) conventional technologies. Empirical data was collected from Finnish companies, providing robust foundation for this comparison. Our study examines operational specifics, economic implications, environmental impacts each method, highlighting advantages drawbacks. By leveraging data-driven insights, we aim to illustrate how MLAS can enhance efficiency sustainability compared traditional methods. In our cost modeling over seven-year period, achieved cumulative €12.76 million, significantly lower than CS, which incurred €21.47 underscoring long-term MLAS. The findings underscore potential advanced AI technologies revolutionize waste management practices, offering significant improvements in accuracy, recovery rates, overall cost-effectiveness. provides valuable perspectives stakeholders industries, emphasizing importance integrating innovative achieve higher goals.

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

This work reports an upgrading reuse of construction-generated sludge waste (CGSM) to manufacture value-added building materials using hydrothermal mineralization (HM). The optimization mixture proportions and the influential factors curing temperature duration were explored. Results showed that high-strength HM-CGSW blocks over 50 MPa with a strength-to-calcium ratio 2.95 MPa/percentage can be produced under optimal Ca/Si 0.5 HM 200 °C for 12 h. production block would generate 305.81 kg e-CO2/m3 cost 222.44 CNY/m3, lower than those concrete autoclaved fly-ash block. An industrial application was proposed use CGSW produce new constructions. findings in this study not only deepen mechanistic understandings treatment waste, but also shed much light on developing path enables sustainable material production.
