The expression “a perfect storm”… can also be used to describe the relationship between the climate crisis and the world’s dependence on concrete. As demonstrated in the Chatham House report, while cement (an essential element for concrete manufacturing) is extremely detrimental to the greenhouse effect and climate crisis –representing about 8% of global CO2 emissions–, its global production is nevertheless expected to increase over the next 30 years….
… Nevertheless, there are some options to make the production of concrete more eco-friendly, and to reduce its use in construction:
AshCrete
Ashcrete uses fly ash…
Finite
Through a method created by a company of the same name, Finite binds together the fine grains of desert sand to create a material that is as strong concrete and that can be easily melted and reused…
Hempcrete
Hempcrete is a mixture of hemp fibers with lime and water…
Mycelium
Mushrooms have the advantage of being materials that can grow under various temperature and moisture conditions…
Ferrock
Discovered by mistake by researcher David Stone, Ferrock is created from steel powder – which is usually discarded from industrial processes – and silica from ground glass…
GrapheneCrete
Graphene is a nanomaterial composed of carbon and the thinnest known crystal…
It is important to note that creating a product that can be used as widely and as often as concrete is not an easy task. In this sense, investments in innovation and research are essential.
