Ugandan Innovators on a Mission Against Food Waste
Sandra Namboozo and Samuel Muyita, two visionary entrepreneurs from Uganda, have gained international recognition for their groundbreaking invention aimed at tackling food waste. Selected as one of the top ten innovators for the Young Inventors Prize 2025, their innovation addresses a pressing global issue—food loss and waste—which accounts for 8-10% of annual greenhouse gas emissions. With over 1 billion tonnes of food wasted annually while more than 783 million people suffer from hunger, their work is not just timely, but essential.
A Simple Yet Effective Solution
The duo has crafted a unique plant-based sachet that significantly extends the shelf life of fresh fruits by up to 30 days. Their product is designed to protect vulnerable produce, allowing smallholder farmers to maximize their yields and fight against the devastating economic impacts of post-harvest losses, which can reach as high as 40% globally. Drawing from their farming backgrounds, Namboozo and Muyita are passionate about finding solutions that directly benefit farmers.
How the Sachets Work: A Scientific Breakthrough
The sachets function by releasing a combination of plant-derived volatile organic compounds (VOCs) that inhibit ethylene production, the gas responsible for fruit ripening. Compounded from natural materials like cloves, lemongrass, eucalyptus, and wintergreen, these sachets prevent spoilage caused by mold, fungi, and bacteria. In research conducted with Uganda's National Agricultural Research Organization, mangoes stored with the sachets remained fresh for 33 days compared to just 11 days without them. This breakthrough not only extends fruit longevity but also underlines the potential of sustainable products in agriculture.
Entrepreneurs with a Vision
Namboozo and Muyita’s journey began at Makerere University, where their shared goal of reducing food waste led to the inception of their company, Karpolax, in 2020. Their commitment to creating environmentally sustainable yet economically viable solutions sets an inspiring benchmark for young entrepreneurs across Africa. The affordability of their sachets means they can cater effectively to small farmers and local markets, empowering them to turn profit from what was once wasted.
The Broader Impact on Environmental Sustainability
As the world grapples with climate change and environmental degradation, innovations like those from Namboozo and Muyita represent a light at the end of the tunnel. The ability to prolong the life of perishables ensures not only that food reaches consumers but also that less waste is generated overall. This aligns with global initiatives aimed at reducing emissions and creating sustainable practices within agriculture.
Future Aspirations
The pair are not resting on their laurels. With their sights set on expanding operations across Africa, they are eyeing markets in Kenya and Rwanda, among others. Their ambition to scale their business means reaching out for additional funding and partnerships, a common challenge for many innovators starting with a limited budget. But the team's dedication to fostering tangible change within their communities is unwavering.
Encouraging the Next Generation of Innovators
The recognition by the European Patent Office honors not only Namboozo and Muyita but serves as inspiration for other young innovators who aspire to create social change through sustainable practices. Their story encourages aspiring inventors to harness their backgrounds and experiences in order to develop solutions for crucial global challenges.
Conclusion: The Call for Action
As we continuously seek innovations that can mitigate food waste, supporting entrepreneurs like Sandra Namboozo and Samuel Muyita through advocacy, funding, and market access can lead to more groundbreaking solutions. Their journey embodies hope, ambition, and the power of sustainable choices that can significantly alter the agricultural landscape across Africa.
