Upcycle High Value Products from Waste Soda-Lime Glass
Alkaline Digestion of Waste Glass
Tags: The University of Queensland, Australia, Energy & Environment, Industrial Automation & Manufacturing
UQ researchers have developed a process to extract high-value products from soda-lime glass, optimizing conditions for efficient alkaline digestion and separation. This technology enables the production of liquid alkali-silicates, high-purity silica gel, and Calcium Silicate Hydrate (CSH) from waste glass. It targets the low-value fraction of glass, transforming it into commercially valuable products without the need for color sorting. The process is noted for its high raw material and energy efficiency, offering reduced capital and operational expenses. Its applications include reducing landfill waste and consumption of virgin materials, presenting significant commercial and social benefits.
