Students at Fundación Bios Terrae - ICAM Ubaté have proposed a “Community Air Quality Program” to address the air pollution crises and to improve the health of 200,000 people living in Ubaté.

Students at Romain-Rolland Gymnasium have proposed to build a lighthouse powered by solar energy an electrolysis-based fuel cell, and run workshops and events from inside the solar lighthouse, creating a space in which students can learn and experience for themselves what it means to develop sustainable alternatives to fossil fuel energy.

Students at Gifted Students School proposed a project to develop a hydroponic greenhouse in which food can be grown all year long. The greenhouse would be controlled by cellulosic cooling cells supplied with water from a sustainable source (groundwater) and air vacuums, as well as temperature controllers supplied with electricity through solar panels.

Students at UWC East Africa - Arusha Campus want to reduce the prevalence of dental & skeletal fluorosis by tackling their community’s drinking water issue: about 50% of spring water sources in Arusha possess fluoride concentrations above WHO’s permissible levels. They have proposed a project to create sustainable bone char water filters by sanitising locally-sourced animal bones and burning them using biomass from nearby farms' agricultural residue. Team Maji Safi's filters will then be distributed to local households and schools to lower fluoride levels by up to 99% in drinking water to prevent long-term exposure to fluoride among Tanzanian youth.

Students at Dhaka Residential Model College have proposed a project to produce healthy crop plants in a faster time by shortening the seed germination period, increasing germination rates, and enhancing seedling growth using soil dwelling microorganisms. The project aims to supply microorganism-based seed and soil treatment chemicals, microbial bio-fertilizers and biopesticides to 2000+ farms and reduce the information gap of Bangladeshi farmers through rural campaigns and consulting services.

Students at Kamil Muslim College proposed a project to address the effects of climate change that have affected their community and the world by providing 100% solar energy to the school, collecting rainwater from a rain harvesting system, generating biogas energy for cooking in the school canteen, and providing food for students who cannot afford lunch.
