The paper presents a comparison of the concentration methods conventional jig, air jig, and sensor-based sorting to treat construction and demolition waste. All tests were made with concrete, brick, and gypsum particles and the tests aim to separate these materials into different size ranges, depending on the method. The equipment tested, conventio...

A literature review comprising 163 publications published over a period of 26 years from 1992 to 2018 is presented in this paper. This review discusses the generation and recycling of construction and demolition waste (CDW) as well as its main uses as raw materials for the construction engineering sector. This review pays attention to the use of CD...

An inorganic sludge from construction and demolition wastes (ICDW) was grafted with APTES to obtain an inorganic-organic modified adsorbent ICDW-APTES. This adsorbent was successfully employed for ciprofloxacin (CFX) adsorption and treatment of synthetic hospital effluent. The chemical composition of ICDW presented large quantities of SiO2 and Al2O...

Large quantities of construction and demolition waste is generated annually around the world. Part of this material is processed in recycling plants. After removing metals, fines and lights, the construction and demolition waste is crushed and sized and can be used as aggregates for low resistance concrete, for road sub-base, city landfill and othe...

This study aimed to investigate phosphate removal from aqueous effluents by an inorganic sludge from the inert part of construction and demolition wastes (CSW) as adsorbent. It is also discussed the application of the loaded P adsorbent as potential fertiliser. The CSW was also thermally treated at 800?°C for 2?h (CSW-T), and its influence in the P...

Concrete slurry is an abundant, cheap, and commonly found waste all over the world where construction activities take place; concrete slurry, which is rich in calcium and metallic oxides, could be successfully employed in the phosphate (P) removal from aqueous media. For the first time, the effect of the carbonation process on concrete adsorbent pr...

There are various patterns of construction and demolition waste (CDW) recycling plants combining different stages of the process like extraction of metallic elements and light elements, crushing, screening and clay flocculation. While most recycled plants have very simple processes and are hard to combine all the previous equipments, processes that...

La production des Déchets de Construction et de Démolition (DCD) peut combiner diverses opérations, telles l'élimination des éléments métalliques ou légers, le concassage, le criblage et la floculation des argiles. La plupart des plateformes de recyclage fonctionnent dans des configurations simples, sans faire appel à l'ensemble de ces techniques, ...
