Abstract
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, conventional jig, air jig, and sensor-based sorting present good results to concentrate construction and demolition waste particles, with different concentrations and mass recoveries. The results show particularly good mass recoveries and particle concentration for conventional jig, especially for concrete and gypsum particles. Sensor-based sorting should preferably use concentration circuits for best results.

The present paper provides a technical comparison among the Minerals 2021, 11, 904 three most promising methods of upgrading coarse Construction and demolition waste (CDW) recycling: conventional jigging, dry jigging, and sensor-based sorting
The results presented in the jigging tests are very promisingChamber for the use of conventional jigs in the Particles treatment of CDW
Summary
Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. Construction and demolition waste (CDW) is a mixture of different solids [1,2,3]. Their use, without any treatment, is generally restricted to landfills, causing environmental problems [4,5]. Part of the CDW consists of inert materials that can be reused in civil engineering as aggregates [6]. For that purpose, their separation by species or group of materials with similar properties is required
