“…In waste processing, manual sorting by humans is still widespread today. However, the purity and thus the value of recovered material can be significantly increased by using sensor-based sorting systems [52]. This is urgently needed because, for example, a directive of the European Union mandates an increase in municipal waste recycling rates of one percentage point per year from 55 to 65 % by weight for the years 2025 to 2035 [53].…”

Sensor-based sorting describes a family of systems that enable the removal of individual objects from a material stream. The technology is widely used in various industries such as agriculture, food, mining, and recycling. Examples of sorting tasks include the removal of fungus-infested grains, the enrichment of copper content in copper mining or the sorting of plastic waste according to the type of plastic. Sorting decisions are made based on information acquired by one or more sensors. A particular strength of the technology is the flexibility in sorting decisions, which is achieved by using various sensors and programming the data analysis. However, a comprehensive understanding of the process is necessary for the development of new sorting systems that can address previously unresolved tasks. This survey is aimed at innovative researchers and practitioners who are unfamiliar with sensor-based sorting or have only encountered certain aspects of the overall process. The references provided serve as starting points for further exploration of specific topics.

“…From another perspective, solid waste is a source of recyclable materials such as metals and plastics, and recovery of the materials is important considering the global or local strain of different resources [2]. Processing municipal and industrial solid wastes has been attracting the attention of researchers working on developing and optimizing solid waste sorting technologies such as magnetic sorting, eddy current sorting, ballistic sorting, and gravity sorting [1][2][3]. Solid waste sorting helps concentrate or purify wanted substances and discard unwanted substances.…”

Solid waste sorting is an important pre-treatment in recycling to improve the efficiency of material recovery and reduce costs. Motivated by the PEACOC project on metal recovery from solid wastes, an innovative magnetic density separation (MDS) process has been developed for solid waste sorting. It has intrinsic advantages over conventional gravity separation technologies and the previously industrialized MDS process. The new MDS process applies an inclined planar magnet and a horizontal basin containing a static magnetic fluid as the separation medium. A particle sliding phenomenon is identified as a feature that could help the separation. Experiments have been carried out to demonstrate the role of the MDS in concentrating valuable metals in shredded PCBAs and reducing metallic contaminants in plastic fractions of shredded wires. A pilot scale facility is introduced to show the design to achieve continuous production and to reduce the consumption of ferrofluid.
