The students at Centro Etnoeducativo Integral Rural Nuestra Señora del Carmen want to solve their school’s lack of access to drinking water problem. They are proposing to implement a reverse osmosis filtration systems to generate drinking water with the power of photovoltaic solar energy, managing the community's human waste by building dry washrooms, and hosting educational programmes on environmental and girls’ menstrual health.

The students at Escuela Técnica Nro.3 Maria Sanchez de Thompson have proposed a project to help diagnose water quality in areas where there is no access to reliable drinking water. Their project involves developing a low-cost kit. A photo is taken of the collected water sample and is loaded into a progressive web page (WPA) that shows if there is a presence of microorganisms using artificial intelligence.

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 Gymnasium Kreativno pero have proposed the “Classroom for the Sustainable Future” to address the problem of toxic materials used in school supplies, toys, and other products. The project entails quipping a classroom with solar-powered 3D printers that use corn-based PLA plastic. The printed products, including school supplies and toys, will be completely biodegradable and non-toxic. Students will learn how to work on 3D printers, and why it is important to use healthy materials and renewable energy resources; they will develop an algorithmic way of thinking accompanied by empathy for the environment.

Students at Northfleet Technology College have proposed a project to engage, restore, and explore a nearby nature preserve to promote students’ connection to nature. The school already has a weather station and four wildlife cameras powered solar PV. This project intends to take this further and use photographic/video methods and AI recognition systems to record the range of birdlife. The project also plans to create a small remote classroom powered by renewables. Furthermore, as part of this project, the school will rehabilitate an existing pond.

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 JSS Private School have proposed the “Blue-Green Solution for Global Warming, Food, And Energy Crisis” project, which aims to cultivate algal biomass that will be used for various applications to reduce the energy, food, wastewater, and pollution. The project will use innovative technology to convert microalgal biomass produced during wastewater treatment into carbon-neutral products such as biofuel, feed, bio-fertilizer, bioplastic, exopolysaccharides, and value-added products like food supplements, pigments, and biopolymers.

Students at Obour STEM School have proposed to build a sustainability laboratory that will be powered by solar panels, employ wind turbines for additional energy that can be stored for use during power outages, and utilise organic waste for both composting and natural gas conversion. Natural gas will be used in chemistry and biology experiments, while compost will be applied to a small fruit garden that provides fruit for student lunches.

Students at Cheshire High School proposed an agro-industrial project that involves post-harvest management of fruits through juice extraction by solar-powered machines. Bio-preservatives extracted from renewable plant materials will be added to the fruit juices, as opposed to the conventional chemical preservation of fruit juice. Biomass will also be used for renewable energy generation for energy and electricity supply in the school and the host community.

Students at Mary Mount Secondary School proposed the “sustainable waste management for clean energy generation” project, which involves the following: 1. Upgrading the school’s pit latrines to flush toilets; 2. Constructing a bio digester to process human waste into biogas or slurry, which will be treated further by a baffled reactor; 3. Another bio digester will be constructed to process animal waste for biogas or manure; 4. A sand filtration unit will be constructed to recycle grey water from the bathroom and kitchen; and 5. The firewood stoves in the kitchen will be replaced with clean biogas burners.

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 Kopila Valley School have proposed the Malilo Mal project, which focuses on composting organic waste and improving the availability of nutritious foods through gardening. The students will first design an experiment to compare two composting methods: 1) vermicomposting, which is practiced in the school garden, and 2) effective microorganism (EM) composting using a locally cultured microorganism-rich liquid, which the school farmers use. Students will test which work best with different kinds of organic household waste, and in different sized areas. The students will put together composting and kitchen garden kits and provide them to families along with training.

They proposed a project to set up solar energy systems to provide electricity for the school as well as a rainwater harvesting and purifying system on the campus to provide safe drinking water.

Students at Bohol Wisdom School have proposed a project that directly responds to the devastation of Super Typhoon Rai in December 2021. The storm was not only detrimental to the community but also the endangered tarsiers, the world’s smallest primates. The student-led project would install solar panels on the school's rooftop, create a solar-powered Upcycling Facility that converts waste materials into other usable and functional products, and scale the school’s solar-powered wildlife monitoring robot prototype that monitors endangered tarsiers.

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.

Students at Sangam Sadhu Kuppuswamy Memorial College have proposed a project to transform the school by converting it to solar and water-generated energy while also building out its health infrastructure. The project involves changing high power-consuming appliances to energy saving appliances, eliminating practices which waste electricity, and installing solar panels throughout the school. They also plan to generate electricity from water turbines that will operate during the rainy season and help offset solar power generation. The water will be harvested and stored for school agriculture. Lastly, they wish to convert a vacant building into a health clinic and gym.
