The Geneva Challenge 2018:
SDSN Youth Special Prize
On the occasion of the 2018 Geneva Challenge, the SDSN Youth Special Prize is awarded in partnership with the Sustainable Development Solutions Network - Youth (SDSN Youth) to the project "Enhanced Sustainable Concrete: Combining Existing Technologies in a Novel Manner to Promote the Sustainable Development of Water and Concrete Industries Worldwide".
Their project, as well as the ones of the finalist teams, will be showcased on the Youth Solutions Report platform. Through its activities and initiatives, which benefit from SDSN's network of institutional partners, experts, private companies and media outlets, SDSN Youth facilitates the dissemination of promising youth-led solutions, giving them additional fora to showcase their work and opportunities to draw interest from potential supporters. In turn, this helps investors, donors and supporters better understand the multi-faceted role of young people in the 2030 Agenda.
Enhanced Sustainable Concrete - Combining existing technologies in a novel manner to promote the sustainable development of water and concrete industries worldwide
Team from North America ¦ University of Toronto
The integration of existing technologies in concrete science and water desalination is a project that will allow developing countries to promote economic and infrastructure development, while mitigating impacts to the environment. The objective is to recycle reject brine produced from water desalination processes and combine it with emerging bioconcrete technologies to produce enhanced sustainable concrete, which can be used in a variety of structures. By substituting the potable water used in concrete mixtures for reject brine, more water is available for consumption in areas with limited drinking water access, and virtually eliminates the need for costly brine management and disposal in the marine environment. Simultaneously, scientific evidence shows that brine can enhance concrete quality. When mixed with concrete that uses recycled waste aggregates and bacterial amendments for self-healing, it produces enhanced sustainable bioconcrete that is cost-effective, stronger, more durable and produces significantly less carbon emissions than conventional concrete mixes.
This novel integrated bioconcrete technology will improve the quality of infrastructure that requires less rehabilitation and repair, thereby preventing significant costs to municipalities. Developing such a project will allow vulnerable societies to be more resilient to climate change by increasing access or developing new sources of potable water through water desalination, as well as limiting issues in poor infrastructure by promoting sustainable and durable structural materials. As previously mentioned, this project will also mitigate carbon emissions produced by concrete and water desalination industries.
This type of project is particularly needed in a context of social and economic development where water scarcity remains unsolved in many regions of the world, which will be exacerbated by climate change. Sites where the project could be implemented will be assessed under particular considerations to develop the most suitable programs for the implementation of enhanced sustainable bioconcrete, taking into account site specificity and current circumstances. Overall, the application of this project aims to advance multiple United Nations Sustainable Development Goals including, Clean Water and Sanitation; Industry, Innovation and Infrastructure; Life Below Water; Sustainable Cities and Communities; and Responsible Consumption and production.
