Approximately 10 billion tons of fine and coarse aggregate are manufactured worldwide annually, solely to be used as concrete for constructed structures. With approximately 80% of conventional concrete comprising sand and stone, activities in their extraction and relocation harm the natural environment. Manufacturing concrete causes substantial amounts of ecological damage and energy consumption. The replacement of natural aggregate with waste glass, therefore, theoretically removes this environmental damage and energy consumption. The research presented in this paper tested the theory that waste glass concrete aggregate represents a potential solution to curtail the adverse impact of concrete on the natural environment. Testing this theory entailed the review of the existing literature and analyses of the findings from a survey of 107 organizations situated in five countries within the concrete manufacturing supply chain. The findings of this research demonstrate that environmental implications exist with the use of both natural aggregate and glass waste. Significant CO2 reductions can be achieved by using glass as aggregate in concrete. This is found to be up to 60% and 65% for fine and coarse aggregates, respectively. In addition, using glass in its aggregate can potentially improve the strength of concrete. With a concrete grade of 20, an improved compressive strength test of up to 10 could be possible. Similarly, with concrete grades of 25 and 30, an improved tensile strength test of up to 9 could be possible. This depends on differences in the percentage of natural aggregate that has been substituted with glass.
