Across the world, more than 1.3 billion tons of food waste are generated every year. In Africa alone, nearly 50 million tons of edible leftovers are discarded, while in Tanzania, households produce an estimated 4,000 tons of waste daily, over 60% of which is organic food waste. Much of this ends up in open dumps or landfills, releasing methane, a potent greenhouse gas. Meanwhile, farmers face high fertilizer costs, and soil continues to lose their natural fertility.
In Mbezi Beach, Dar es Salaam, this global challenge is felt locally. Waste collectors visit neighborhoods only a few times a week, forcing families to store food waste for days. Spoiled leftovers attract flies and rats, turning kitchens and yards into breeding grounds for disease. At the same time, nearby farmers struggle with depleted soil and high fertilizer prices, making it difficult to grow vegetables and maintain small farms.
Recognizing this gap, the Human Dignity and Environmental Care Foundation (HUDEFO) turned the challenge into an opportunity. On April 1, 2025, HUDEFO launched a community composting program in Mbezi Beach to transform household food waste into nutrient-rich organic manure. The concept was simple but powerful: instead of letting food waste rot and pollute the air, it is collected, composted, and returned to the soil.
“I am a strong supporter of environmental protection. When HUDEFO first told me about food waste, I wanted to learn more, so I followed every step until the compost was finally made. Truly, it is a very good initiative, and I wish this knowledge could reach many more people.” - Mama Mwakatobe, Resident of Mbezi Beach Kati.
The program began with direct community engagement. HUDEFO trained 15 households near its office at Mbezi Beach Shule on how to separate food waste from plastics and other trash. Each household received dustbins, and a collection routine was established every after two (2) days to prevent spoilage. The collected food waste was then composted using low-cost, environmentally friendly methods to produce high-quality organic manure at the HUDEFO premises.
The results were significant. In just six (6) months, these households generated over 5 tons of food waste, which HUDEFO converted into 1.8 tons of compost. The compost has been distributed to four households to support vegetable gardens, while the remainder enriches the HUDEFO demonstration garden, providing fresh produce for staff and training sessions. Families report cleaner kitchens, fewer pests, and reduced odors, while children actively participate in separating food waste, learning important lessons about sustainability.
“As a farmer and livestock keeper, I was surprised when HUDEFO first approached me about collecting food waste to make compost. At first, I didn’t fully understand the idea, but I decided to give it a chance. Over the past six months, I’ve learned how to turn waste into fertilizer, and HUDEFO has even supported me in my gardens. Today, my vegetables are thriving with the compost they helped us create. I am truly grateful for this knowledge and the positive change it has brought to my farm.” - Mama Nappe, Resident of Mbezi Beach Kati
Beyond reducing waste, the program offers multiple benefits for families and the wider community. Composting decreases the amount of waste sent to dumpsites, lowers greenhouse gas emissions, and discourages open burning of garbage. Households benefit from cleaner surroundings, fewer odors, and reduced dependence on expensive chemical fertilizers, while the nutrient-rich compost improves soil fertility, enabling families to grow their own vegetables and strengthen food security.
“HUDEFO has really helped us manage household food waste in our neighborhood. Before, we struggled with the bad smells from leftovers staying too long, but that problem has reduced significantly. They even helped me start a vegetable garden using compost made from the food waste we collect, and it has made such a positive difference.” - Shekh Suleman, Resident of Mbezi Beach Shina
The initiative also fosters a culture of responsibility and environmental stewardship. Participating in households contribute to cleaner neighborhoods, healthier environments, and stronger local food systems. Children gain hands-on experience in sustainability, creating a generation more aware of their environmental impact.
Moving forward, HUDEFO aims to expand the community composting program to reach more households and neighborhoods, increase compost production, and establish additional collection points. The organization plans to strengthen partnerships with local authorities, schools, and donors, while continuing to provide training and resources to empower communities. By scaling these efforts, HUDEFO seeks to transform food waste into a sustainable resource, improve soil fertility, support local food production, and foster lasting environmental awareness and stewardship across the region.
Join HUDEFO today at the Mbezi Beach composting site to learn, support, and be part of this movement. Together, we can turn food waste into a valuable resource that nourishes families, restores soil, and protects our planet.
