Abstract

This study reviews various mechanical sorting options in the field of solid waste. The interest towards the reuse of waste materials is growing due to the tightened regulation and increasing demand for recycling. The effective reutilization of waste material will be needed sorting technologies, which can be based on the different properties, such as density, electric conductivity, and other surface properties. Several technologies based on sorting were presented decades ago, but in the field of waste, several studies have been published recently that demonstrate to theme being is an essential issue currently. The review summarizes the potential mechanical sorting technologies for solid waste, which were discussed in accessible literature during the last decades. The different methods are included, based on the material properties such as, size, gravity, magnetism, surface tension, electric conductivity, or combinations thereof. The emphasis of technologies are targeted at the methods that are suitable for solid waste material, which can be reused as a raw material in the manufacturing of the products, such as composite production. This kind of operating model promote resource efficient production and contributing circular economy. It is concluded that the efficient sorting results of solid waste materials can be achieved by a combination of several technologies, but a lot of studies will be still needed in the future.
