Uganda Martyrs Namugongo Students Turn Organic Waste into Soap in an Innovative School Project on Sustainable Waste Management
*****The students were supervised by researchers from the College of Agricultural and Environmental Sciences (CAES) at Makerere University, led by Prof. Fred Kabi.
The garbage challenge
With urbanization rates rising rapidly across Uganda, municipal solid garbage generation in the country’s cities is projected to increase by more than 40 percent by 2050. The growing burden of unmanaged garbage, particularly organic garbage, continues to pose environmental and public health risks, underscoring the urgent need for innovative and sustainable solutions.
It is against this backdrop that Senior Four students of Uganda Martyrs Secondary School Namugongo undertook a project to demonstrate how local market garbage challenges can be transformed into opportunities for sustainable development.
Addressing the garbage Challenge
As part of their academic project under the competence-based curriculum, the students were tasked with identifying real-world challenges within their communities and developing practical solutions using locally available resources. Through research and field observations, they identified poor garbage management, particularly the accumulation of organic waste at major dumping sites such as Kiteezi Landfill, as a critical issue.
At these sites, unsorted solid garbage often accumulates uncontrollably, sometimes leading to collapses that pose serious environmental and public health risks including water contamination by leachates, persistent foul odors, and disease outbreaks.
Rather than solely viewing solid market garbage as a problem, the students recognized its untapped potential within the biodegradable fraction of market garbage streams. Their innovative solution was to convert organic solid market waste (biodegradable garbage) into an industrial raw material for soap production by utilizing saprophagous Black Soldier Fly larvae (BSFL) to accumulate lipids and applying the scientific process of saponification.
Makerere University Support to the project
The students’ project was supervised by Prof. Fred Kabi together with technicians from the College of Agricultural and Environmental Sciences (CAES) at Makerere University. Prof. Kabi and his team have been actively researching on Black Soldier Fly Larvae (BSFL) as a bio-waste management technology capable of converting biodegradable solid municipal garbage and farm waste into valuable by-products such as organic fertilizers, animal feeds, soap, and biodiesel.
Working in collaboration with Ento Organic Farm Uganda Ltd, the researchers have demonstrated how insect-based waste conversion systems can support a circular economy by transforming biodegradable waste into industrial raw materials.
According to Prof. Kabi, the five young garbage entrepreneurs (students) began their project by collecting information on household garbage management practices. After analyzing the data, they engaged stakeholders along the garbage value chain to brainstorm all-inclusive, source-based waste management strategies.
“The students developed a solution that links efficient waste management at garbage generation source to support production of organic fertilizer, insect protein for animal feeds, and soap, which is only possible with biodegradable garbage,” Prof. Kabi explained. “This approach of the Competence Based Curriculum (CBC) for lower secondary schools supports the concept of taking Makerere University to the community of budding scientists while promoting sustainable community development through a circular economy.”
From Market Waste to Soap Bars
The Team leader, Ms. Ivy Stephanie Kitali explained the step-by-step scientific process behind the project. The students began by collecting organic waste from local markets, which was then shredded to prepare it for the larvae as a substrate. “Black Soldier Fly larvae were then introduced to the prepared waste. The larvae efficiently consumed the organic matter, greatly reducing its volume while accumulating lipids (fats) in their bodies. After maturation, we separated the larvae from the remaining waste, euthanized through blanching and dried it. Oil was then extracted from the dried larvae using ethanol as a solvent. This lipid-rich oil became the primary ingredient or raw material for soap production. To enhance the final product, the larvae oil was blended with minute quantity of sunflower oil before adding sodium hydroxide, initiating saponification, the chemical reaction that transforms fats and oils into soap,” she explained. The process ultimately yielded usable bars of soap derived entirely from what had once been discarded as unwanted market waste/garbage.
Building Skills and Sustainable Innovation
Beyond producing soap, the project provided students with hands-on training in scientific research, waste management techniques, bio-chemistry, and sustainable innovation. They gained practical exposure to insect-based biotechnology and learned how environmental challenges can be addressed through science-driven by entrepreneurship.

Africa Climate Collaborative: Masters & PhD Scholarship Announcement Academic Year 2026/2027
*****The two-day training, hosted by the College of Agricultural and Environmental Sciences (CAES) at Makerere University, was conducted under the auspices of the APPEAR Collaborative Research Project, ‘Clean and Prosperous Uganda – Fecal Sludge and Solid Waste Management for Improved Livelihoods (CPUg).
The challenge of waste management in Uganda
Fecal Sludge Management (FSM) and Solid Waste Management (SWM) are essential for building healthy, resilient communities. However, in many parts of Uganda, these systems remain underdeveloped, leaving communities exposed to a wide range of complex challenges.
Improper handling and disposal of fecal sludge and solid waste pose both immediate and long-term public health risks, including the spread of waterborne diseases like cholera, typhoid, and dysentery. When human waste is not safely contained, treated, or disposed of, pathogens can contaminate water, food, and soil, disproportionately affecting vulnerable groups such as children and residents of informal settlements.
Environmentally, unmanaged waste degrades ecosystems, pollutes rivers and wetlands, and contributes to greenhouse gas emissions. Open dumping clogs drainage systems, heightening urban flood risks and facilitating disease transmission. Non-biodegradable materials, including plastics, can persist for decades, blocking waterways, harming wildlife, and weakening communities’ resilience to climate change.
The economic consequences are equally profound. Inefficient waste management undermines productivity by driving up healthcare costs, lowering property values, and limiting tourism and investment opportunities. Informal waste collection systems, often the only coping mechanism for many urban residents, fail to provide adequate protection for workers.
Given these intertwined health, environmental, and economic impacts, the burden of fecal sludge and solid waste in Uganda is not merely a municipal concern but a pressing national development issue. Urgent attention is required to invest in modern FSM and SWM infrastructure, promote behavioral change, and implement regulatory frameworks that ensure safe, sustainable, and inclusive waste management solutions. Without such interventions, the compounded risks to human well-being, ecosystems, and economic growth will continue to escalate.
Addressing the Challenge through the CPUg Project
The Clean and Prosperous Uganda – Fecal Sludge and Solid Waste Management for Improved Livelihoods (CPUg) Project, a collaborative initiative between the CAES, the Institute of Water Quality and Resource Management at Vienna University of Technology in Austria, the Department of Environmental and Livelihood Support Systems at Mbarara University of Science and Technology (MUST), and the Uganda Red Cross Society, seeks to tackle Uganda’s most pressing challenges in waste management.
The project set out to explore circularity concepts, test a variety of techniques for utilizing dried fecal sludge, analyze plastic recovery from existing composting plants, and evaluate the social and economic viability of improved FSM and SWM and their influencing factors on regional communities. Supported under the Austrian Partnership Programme in Higher Education and Research for Development (APPEAR), the project aims to examine how best to optimize and integrate FSM and SWM in rural settings in Wakiso District, refugee settlements in Arua District, and Uganda in general.
In addition to the technical aspects, the socio-economic viability of improved fecal sludge and solid waste management is being evaluated in terms of affordability, perceptions, and the willingness to accept and utilize these products. The project aims to contribute towards reshaping Uganda’s landscape through integrated solutions, scientific rigor, and inclusive community engagement. It stands as a model for integrated development.
It is coordinated by Prof. Jeninah Karungi Tumutegyereize from the Department of Crop Science and Horticulture at CAES, Makerere University.
Two-Day Training on Integrated Fecal Sludge and Solid Waste Management
The College of Agricultural and Environmental Sciences at Makerere University, in collaboration with the Uganda Red Cross Society, Mbarara University of Science and Technology, and Vienna University of Technology, Austria, held a comprehensive two-day training on Integrated Fecal Sludge and Solid Waste Management.
The training, conducted on 30th-31st March 2026, at Makerere University was officially opened by the Principal of CAES, represented by Dr. Mildred Ochwo Ssemakula, Head of the Department of Crop Science and Horticulture. Participants included representatives from academia, the private sector, municipal authorities, service providers, and farmers.
The training programme aimed to equip personnel across the waste management value chain with the knowledge and skills to transform fecal sludge and solid waste into valuable, sustainable agricultural and economic resources. It covered topics such as occupational safety, waste management infrastructure, processing and post-treatment methods, composting, carbonization, material flow analysis, service gaps, and economic considerations in Greater Kampala. Participants were also trained in specialized software tools designed to enhance efficiency and manage waste-to-resource processes, promoting both environmental sustainability and economic viability.
Particular emphasis was placed on shifting perceptions of fecal sludge-based products among end users, mainly subsistence and commercial farmers.
Emerging Issues from the Training

RUFS Project Team Enhances Capacity of Smallholder Farmers in Mbale City in Financial Management & Communication
Achieving lasting and sustainable success in agriculture goes far beyond planting and harvesting. It requires a diverse skill set, including financial literacy to manage budgets and make sound investment decisions, as well as effective record-keeping to track performance, inform operations, and identify opportunities for improvement. Equally important is strategic communication, which enables farmers to market their products, build brand visibility, and enhance profitability.
A strong understanding of group dynamics is also essential in helping farmers foster collaboration within cooperatives, community initiatives, and peer networks. By integrating these competencies, agricultural entrepreneurs can maximize productivity, optimize resource use, and build resilient enterprises capable of adapting to evolving environmental, economic, and social conditions.
Despite the vital role urban farmers play in ensuring food security, many still lack the technical knowledge and skills needed to optimize productivity. This gap limits output and undermines the profitability, efficiency, and long-term sustainability of their farming enterprises.
Addressing the Skills Gap Through Phase II of the RUFS Project
Phase II of the Resilient Urban Food Systems (RUFS) Project aims to address these challenges. Through hands-on training programmes in Mbale City and Kasese Municipality, the initiative seeks to equip urban farmers with practical knowledge, modern techniques, and adaptive strategies to improve productivity.
Led by Prof. Frank Mugagga from the Department of Geography, Geo-Informatics, and Climate Sciences at the College of Agricultural and Environmental Sciences (CAES), Makerere University, and supported by the AgriFoSe2030 Programme, the project focuses on strengthening urban food systems to withstand climate-related shocks such as floods and droughts. By promoting climate-smart agricultural practices, the initiative empowers farmers to sustain productive, profitable, and resilient operations, ultimately improving livelihoods and contributing to stable urban food supplies.
Training Sessions in Mbale City
To enhance their skills, the RUFS Project team held training sessions for smallholder farmers in Mbale City on 26th-27th March 2026. Hosted at the home of Hajji Siraji Kamulegeya, a mixed farmer in Nankusi Cell, Northern Division in Mbale City, the training provided a community-centered setting that encouraged active participation and peer learning.
A total of 25 farmers attended the training, which aimed to strengthen financial literacy and enhance overall farm management practices. The sessions covered essential topics such as effective bookkeeping, farmer group dynamics, systematic documentation of farm activities, and the strategic use of media to share knowledge and promote agricultural products and services.
Farmers actively engaged in the discussions, openly sharing their experiences and the challenges they encounter. Many confessed that they did not maintain proper financial records, citing limited knowledge of record-keeping practices, the busy schedules, and, in some cases, low motivation to adopt structured documentation systems.
Training in Financial Management
In a comprehensive training session focused on bookkeeping, Mr. Mbowa Henry from AidEnvironment, also a member of the RUFS Project, emphasized the critical importance of maintaining accurate, consistent, and systematically organized financial records. He noted that proper record-keeping not only improves financial management but also strengthens farm management and promotes long-term economic sustainability of farming enterprises.
He introduced the farmers to the core components of an effective record-keeping system, including cashbooks, receipt books, expenditure registers, and bank records, tools essential for monitoring income, tracking expenses, and evaluating overall performance.
He encouraged the participants to actively apply the knowledge acquired, stressing that consistent adoption of these practices would empower them to optimize their farm operations, enhance productivity, and secure sustainable financial growth for their agricultural ventures.
Managing Farmer Group Dynamics
In addition to financial skills, the RUFS Project team, led by Mr. Mbowa and Ms. Ritah Pavin Nakanjako, provided guidance on farmer group dynamics. Discussions centered on common challenges affecting collective farming and strategies to address them. Key challenges identified included the lack of shared goals, conflicting individual interests, weak saving culture, leadership gaps, unregistered or family-centered groups, low participation in group activities, uncoordinated initiatives, politicking, and limited financial management skills, all of which hinder the success of farmer groups. The trainers emphasized the importance of unity, clear objectives, and structured collaboration in strengthening group performance.
Climate Change Risks
Another significant topic of discussion was climate change and its devastating effects, as well as the social and hydrological histories, emphasizing the urgent need for adaptive strategies in agriculture. The Elgon region, which spans Eastern Uganda’s highlands and the foothills of Mount Elgon, is particularly vulnerable to extreme rainfall, flash floods, and landslides due to its steep terrain, heavy seasonal rains, and densely settled, erosion-prone slopes. Over the decades, such disasters, most notably in 1997-2004, 2010, 2018, 2022, and 2023, have resulted in displacement, destroyed livelihoods, damaged infrastructure, increased food insecurity, and heightened health risks.
During the training, farmers shared firsthand accounts of the devastating impacts of recurrent floods in the region. Facilitated by Mr. David Luswata, a Masters student supported by the project, and Ms. Patricia Kiggundu, a member of the project, the sessions offered a collaborative platform for participants to explore long-term, sustainable solutions aimed at reducing both the risks and economic losses associated with climate variability. As part of his Masters research on flood risk management among smallholder farmers in Mbale City, Mr. David Luswata engaged the farmers on the impact of floods on crops, livestock, property and livelihoods.
Documentation and Knowledge Sharing
The training also emphasized the critical role of documentation in effective farm management and knowledge sharing. Mr. Juma Wephukulu, a member of the RUFS Project and Chairperson of the Mbale City Food Systems Platform, offered detailed guidance on essential practices for recording day-to-day agricultural activities. Drawing from his own experience, Mr. Wephukulu authored a book chronicling his farming journey. Supported by RUFS, the publication serves as an educational guide and an inspirational resource, equipping other farmers with practical insights, strategies, and motivation to enhance productivity and resilience.
Communication and Media Engagement
Another distinctive feature of the training was its focus on communication and media engagement. Farmers were encouraged to leverage media platforms to amplify their voices and share their experiences with wider audiences. Mr. Wataba Shaban, a talk-show host at IUIU FM in Mbale City, led a simulated radio talk-show session, demonstrating effective techniques for communicating agricultural issues and providing participants with practical skills for public engagement.
Community Perspectives
Many of the factors driving climate change are the result of human activity, frequently stemming from unsustainable agricultural practices and improper construction methods. Representing the farming community, Hajji Siraji Kamulegeya called for more educational programmes and capacity-building initiatives to deepen understanding of the causes of climate change and strategies for mitigating its impact. He expressed gratitude to the funders and the project team for the interventions.
Addressing the participants, Mr. Munowa Hassan, LC1 Chairman of Nankusi Cell in Northern City Division, Mbale City appreciated Makerere University for its numerous initiatives aimed at empowering farmers and enhancing food security. He called for the expansion of such projects.
Action Planning
To translate knowledge into action, participants collectively developed a concrete action plan and a monitoring and evaluation framework to track progress, measure outcomes, and make necessary adjustments to achieve the desired impact.
A similar training will be conducted in Kasese Municipality.
