Vitrification and reuse of waste

Vitrification and reuse of several types of waste (e.g. municipal waste incinerator bottom ashes, mining residues, contaminated sediments, air pollution control residues, etc. and combination of them) and investigation of the reuse of the so obtained glasses and glass-ceramics as raw material for the manufacturing of building materials with improved properties (production of sintered – monolithic or cellular – glass-ceramics, or modification of traditional ceramic tiles), or as new sustainable building materials, special cement production and filling of bituminous agglomerates.


Description of work

Task 1.1 Vitrification process of different wastes (task leader UNIPD, other participants: POLITO, ERLANGEN, OMPI)

Manufacturing of glass-ceramics mixing several inorganic wastes, in order to get glass compositions prone to crystallization.  Subsequent sinter-crystallization, which allows the obtainment of glass-ceramic after a very fast processing of powdered glass.

Task 1.2 Vitrified waste as raw material for added value products (Glass-ceramics, fibres, foam) (task leader POLITO, other participants: UNIPD, ERLANGEN, OMPI)

The sintering approach is used for the preparation of glass and glass-ceramic foams, by using the same glasses mentioned in T1.1 mixed with suitable “foaming agents” (substances that generate gasses upon sintering, like carbonates, C-containing compounds etc.).

Task1.3 Prototype testing (task leader UNIPD, other participants: POLITO, ERLANGEN, OMPI)

The samples produced in Task1.1 and Task1.2 will be tested and characterized.

Recruited researchers to be involved (ESR= early stage researcher, ER= experienced researcher)

ESR4 will study the “Reuse of vitrified wastes in cement or bituminous conglomerates”  and will be involved in T1.2 and task 1.3

ESR5 will study the “Sinter-crystallisation of wastes and vitrified wastes” and will be involved in T1.1.

ESR10 will “Glass and glass-ceramic components from inorganic waste and novel processing” and will be involved in T1.1, T1.2 and task 1.3
