Structural and microstructural aspects of asbestos-cement waste vitrification

Crystallization and rheology of Na2O–CaO–Al2O3–SiO2 melt in the vitrification of technological waste

“…Vitrification has been a worldwide recognized solution for treating hazardous waste for decades. 1 By transforming waste substances into durable glass or glass-ceramics materials, the vitrification process is able to stabilize a wide range of dangerous waste, namely, fly ashes, [2][3][4][5][6] bottom ashes, 7 sludges, [8][9][10] asbestos, [11][12][13] medical waste, [14][15][16] metallurgical slags [17][18][19][20] or nuclear waste. [21][22][23][24][25][26][27][28][29][30][31] Thus, vitrification of waste is an attractive approach due to its flexibility to treat various type of hazardous waste.…”

From hazardous asbestos containing wastes (ACW) to new secondary raw material through a new sustainable inertization process: A multimethodological mineralogical study

“…A possible alternative is ACW inertization. Scientific research has been successfully involved in this topic (e.g., Gualtieri et al 2011 and references therein;Iwaszko et al 2018;Ruiz et al 2018), leading to many excellent scientific papers and to J o u r n a l P r e -p r o o f hundreds of patents (35 of which in Italy) dedicated to ACW inertization through thermal, thermochemical and/or mechanical treatments, also providing possible solutions for the inert material reuse.…”

Management of Asbestos Containing Materials: A Detailed LCA Comparison of Different Scenarios Comprising First Time Asbestos Characterization Factor Proposal

“…For this reason, several asbestos inertisation treatments have been proposed in the last decades, most of which has been summarized in a recent review. 11 Particularly, they include chemical, 12 thermal, 13,14 thermochemical 15,16 and mechanical procedures, 17−19 together with those based on vitrification 20 as well as biological treatments. 21 However, although the European Union recently recognized asbestos inertisation as a preferable solution to be adopted instead of landfilling in order to decrease the environmental burdens associated with ACW, 22 most of the proposed methodologies are extremely energy demanding, or not yet sufficiently mature, 11 thus risking to simply move the environmental impacts to a different phase of the asbestos life cycle.…”
