“…X-ray fluorescence (XRF) works at the atomic level, based on the wavelength of X-rays that identify the elements [98]. Even though the use of X-rays is limited [99], XRF system has been used for the analysis of pressure treated wood [100,101] and the identification of flame-retardants in WEEE [102]. In addition, plastic identification based on an X-ray fluorescence detection system has been used together with tracers.…”

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.

“…Its advantages are, among others, that it does not require major prior preparation and a particular speed. Therefore, it is suitable for online applications [101]. The disadvantages of the XRF method are overheating due to high ambient temperature and heat production by the X-ray, coupled with poor cooling of the XRF chamber [100].…”

“…Ademais, o resíduo, quando em contato com substâncias tóxicas, pode tornar-se perigoso, contaminando os corpos d'água e o solo e gerando riscos à saúde pública. Um último impacto é a possibilidade de contaminação do solo pela liberação de materiais químicos que foram agregados à madeira durante seu processo de tratamento e beneficiamento (ZENID, 2009;HASAN;GABRIELE;TOWNSEND, 2011).…”

“…Entretanto, a grande maioria trabalha com madeira serrada e compensado. Sendo assim, consideradas empresas potencialmente geradoras de resíduos, o que pode acarretar problemas ambientais e de saúde pública dos trabalhadores destas empresas e moradores vizinhos, o que já é registrado na literatura (LELIS, 2001;ZENID, 2009;HASAN et al 2011;RIUL;RIBEIRO, 2012).…”
