Potential Role of Vitrification and Waste Vitrification in the Circular Economy

Glasses, Frits and Glass-Ceramics: Processes and Uses in the Context of Circular Economy and Waste Vitrification

“…Consequently, new horizons emerge for conducting research with the mentioned industrial waste to learn the conditions in which they can be rendered inert or used in the composition of traditional materials as a secondary raw material or in the production of new materials [37][38][39]. Following the general increase in population and industrial development, the management of resources by using secondary sources of raw materials, recycling and energy recovery from waste products is growing in importance [24,40]. There are many challenges associated with each approach, with waste treatment and handling its by-products being among the most environmentally concerning matters [24].…”

“…There are many challenges associated with each approach, with waste treatment and handling its by-products being among the most environmentally concerning matters [24]. A chapter of one publication [40] studies the types of waste management: municipal solid waste management and wastewater management. In the first part, management of municipal solid waste, incineration is presented as a tool for energy recovery, and its hazardous by-products (fly ash and bottom ash) are defined.…”

“…In the first part, management of municipal solid waste, incineration is presented as a tool for energy recovery, and its hazardous by-products (fly ash and bottom ash) are defined. The second part of this chapter [40] is dedicated to the potential use of rice husks. The resulting heavy-metal-containing rice husk can be vitrified, and it is possible to prepare foam glass-ceramics after its vitrification [40].…”

“…The second part of this chapter [40] is dedicated to the potential use of rice husks. The resulting heavy-metal-containing rice husk can be vitrified, and it is possible to prepare foam glass-ceramics after its vitrification [40]. Many articles have been published recently on the problem of managing different types of waste that, after proper treatment, can become raw materials for the construction industry and other sectors.…”
