Converting waste glass into waterglass
The aim of this interdisciplinary project is to develop a robust strategy to make waterglass from waste glasses, in particular from waste grades unsuitable for recycle in the glass manufacturing process.

Impact of Research
The technology will provide the opportunity to generate an added-value commodity chemical, i.e. waterglass, in a cost- and energy efficient manner. The advancement will provide an economically-viable route to recycling waste glass. Our project will have an immediate impact on the cementless concrete sector, i.e. will allow making concretes with cementless binders an economically attractive when compared with equivalent Portland cement concretes, with major contribution towards decarbonisation of the construction sector.

Sustainable Development Goals
This project aims to address the following SDGs:
Goal 9 - Industry, Innovation and Infrastructure
This will be achieved by providing opportunity to generate an added-value chemical, i.e. waterglass, in a cost and energy efficient manner.
Goal 11 - Sustainable Cities and Communities
Project fits well within the urban mining strategies for waste management (waste glass) and the 3R policy of circular economy.
Goal 12 - Responsible Consumption and Production
This will be accomplished by conservation of virgin material and instead usage of waste glass in creation of added-value product (waterglass).
Goal 13 - Climate Action
This goal will be reached by lowering the carbon footprint of the high energy demanding waterglass making process, and ultimately in generating ultra-low carbon concrete.
