This paper reviews specific technical and eco-efficiency performance issues in using glass waste as an aggregate in the production of concrete. Eco-efficiency is a relatively modern tool in the pursuit of sustainability. Eco-efficiency is the concept of maximising the benefits from the use of non-renewable resources while minimising the use of non-renewable resources. The paper details a life cycle assessment and eco-efficiency review of a potentially sustainable alternative to traditional concrete, made from ordinary Portland cement. The study follows the ISO framework, which includes goal and scope, a life cycle inventory, life cycle impact assessment, life cycle costing, normalising of data and the creation of an eco-efficiency portfolio. SimaPro life cycle assessment software has been used to further analyse the use of recycled glass aggregate as a replacement for naturally occurring stone aggregate in geopolymer concrete. The study found that the use of geopolymer concrete as a non-cement based alternative concrete was a viable way to reduce emissions with a high global warming potential but faced challenges in other environmental impact areas. There is a need for ongoing research and study on the application of eco-efficiency as a tool in the pursuit of sustainable practices in society. |
