As the first tele-mammography network in Latin America providing preventive, high-quality healthcare to every woman, Mamotest uses tele-radiology, remote analysis provided by top-tier professionals in imaging diagnoses, to democratise access to diagnoses and life-saving services.

Mamotest has detected thousands of breast cancer cases in early stages, which has saved patients’ lives. It has provided quality healthcare to more than 510,000 direct beneficiaries and has created awareness for millions of women. Conceived since its inception as a social-impact company with a central objective, Mamotest is drastically reducing deaths from breast cancer.

S4S Technologies is an SME that is committed to empowering rural women and harnessing new technology to reduce food waste and improve income for farmers. The organisation addresses post-harvest loss through an electricity-free solution that converts farm losses to value-added products, helping farmers to increase their profit by 50–200 per cent.

S4S simultaneously solves three problems—malnutrition in women and kids, food wastage, and low income of farmers—while reducing gender inequality and promoting women entrepreneurship. The technology innovation (the solar conduction dryer) produces preservative-free, nutrition-rich products. It saves 22,500 tons of produce each year from getting wasted and 300,000 tons of CO2 from the environment.

SOLshare is an SME that has created a revolutionary new approach to bringing affordable solar electricity to the energy-poor in remote, rural communities of Bangladesh by installing the world's first peer-to-peer (P2P) energy-trading grid, monetising excess solar energy via mobile money for rural development and empowerment.

To date, ME SOLshare’s P2P energy exchange platform, SOLbazaar, has connected nearly 700 households into 30 microgrids. Targeting the remote population of the river islands of Bangladesh, SOLshare provides affordable access to clean, decentralised energy. SOLshare’s current solution supports rickshaw drivers by helping them close their income gap.

Wateroam from Singapore is a water innovation enterprise that develops one of the world's most portable and efficient water filters to serve rural and disaster-hit communities with safe drinking water. These water filters are built to be simple-to-use, swift to deploy and can even operate without electricity.

Since 2014, Wateroam has provided clean water access through its partners to more than 150,000 people across 38 countries globally including Cambodia, Indonesia, Philippines, Nepal, Malaysia, and Myanmar.

Instituto Iberia from the Dominican Republic plans to convert used cooking oil into biodiesel and use it to power the institution's generator. Through this project, students hope to positively impact the environment and inspire community members to make more sustainable choices. This project will teach students entrepreneurship, how to work with a team, and how to overcome challenges to achieve a goal.

In the next 5 years, it will benefit 10,000 students, as they learn how to apply traditional academic content in real problem-solving scenarios.

Students at the Eastern Mediterranean International School in Israel, have proposed a student-led initiative in engineering, called Project Oasis, that aims to collect electricity and water from the air, simultaneously. The system accomplishes this using organic Rankine cycle and condenser technology.

Their aim is to produce 6 kilowatts of energy and 1,000 litres of water every day with zero infrastructure for every machine that is built. Ultimately, the school plans on mass producing these machines to significantly reduce global water shortages and provide clean water and energy in impoverished areas; all while being carbon neutral in operations.

The solution will continue to deliver benefits to students at the school for the next 50 years.

The school depends on well water for general purpose usage and requests that students bring their own drinking water from home. This project aims to help solve those problems with a sustainable rainwater harvesting solution for the treatment, storage, and reuse of water.

Sustainability outcomes are estimated at two litres of consumable water being available per person per day for the school, totalling 30,720 litres per month, and 368,640 litres saved per year.

The proposed sustainability project, LivingEnergy, uses microorganisms to affordably generate power from used facemasks, addressing the challenge of electricity shortage and an overreliance on nonrenewable energy resources.

The project could eliminate up to 19 kg of facemasks from polluted waters each year and deliver benefits to students and the local community for the next 15 years, impacting 1,000 students in the first five years alone.

Female students in this rural school face the tremendous challenge of lack of access to sanitary products. The project proposes to harvest raw plant materials from local farms to produce sanitary products to improve girls’ health and boost school attendance, enabling underprivileged girls to complete school cycles.

The project is expected to benefit 500,000 students.

UWC ISAK Japan is a member of the global United World College movement, with students coming from 83 different countries. Through this project, the school aims to become the most sustainable school in Japan and a role model for others by taking measures towards various environmental problems inside the school campus. To achieve this, the school will use renewable sources which include a biomass boiler, solar panels, and a rainwater collection system. The school expects to reduce its carbon emissions significantly, become more energy-efficient, produce organic and healthy food sources, and increase awareness of sustainability.

Their environmental measures maximise the strength of the local area by using wood chips from lumber yards and cooperating with local non-profit organisations for energy supply, and sustainable food production. The project will benefit both the local and international community of youth changemakers for the next ten years and impact 520 students directly within the school in the first five years.
