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.

The National Variety Release Committee (NVRC) has officially approved Maksoy 7N, the latest soybean variety developed by the Makerere University Centre for Soybean Improvement and Development (MAKCSID) in the Department of Crop Science and Horticulture, College of Agricultural and Environmental Sciences at Makerere University. The approval was announced during the committee’s 47^th meeting at the National Agricultural Research Laboratories (NARL) in Kawanda on 13^th February 2026.

The NVRC, chaired by Dr. Joseph Kikafunda, is composed of stakeholders from the Ministry of Agriculture, Animal Industry, and Fisheries (MAAIF), research institutes, seed regulatory agencies, farmers’ organizations, and private seed companies. The committee evaluates new crop varieties for performance and traits before official release, helping to enhance national food security.

Rigorous Testing Confirms Superior Performance

MakSoy 7N, a cross between 6N and SG underwent extensive Distinctive, Uniformity, and Stability (DUS) testing across multiple seasons and locations in Uganda, including Kabanyolo (Wakiso), Nakabango (Jinja), Ngetta ZARDI (Lira), Abi ZARDI (Arua), Bulindi ZARDI (Hoima), and Mubuku Irrigation Scheme (Kasese).

The trials were conducted in accordance with the Seeds and Plant Act, Cap. 41 and the UPOV guidelines.

Results showed that the variety is clearly distinct from its closest reference, Maksoy 3N, in pod color, stem hair, and seed hilum, with uniformity meeting the 1% off-type standard, and stability confirmed across locations and seasons. On-farm trials were conducted to test performance under farmers’ management and to determine farmer preferences. Following these findings, the National Seed Certification Service (NSCS) recommended Maksoy 7N for release, providing farmers with a high-yielding and soybean rust-resistant variety.

 Key Reasons Behind the Development of MakSoy 7N

Soybean plays a critical role in nutrition and income generation, offering 40% protein and 20% oil. It is used in human food, livestock feed, agro-industrial applications, and soil fertility improvement, supporting climate-smart agriculture and reducing reliance on synthetic fertilizers. It also breaks pests life cycle if included in the cropping system.

Maksoy 7N was developed to address yield stagnation, rising disease pressure (including soybean rust), and growing national and regional demand for high-performing varieties. Advanced yield trials across six locations – Kabanyolo (Central), Nakabango (Eastern), Bulindi (Mid-West), Ngetta (Northern), Abi (West Nile), and Mubuku (Western) – demonstrated the variety’s strong performance in both multi-environment trials and participatory on-farm evaluations.

According to Prof. Phinehas Tukamuhabwa, Principal Investigator and Director of MAKCSID, Maksoy 7N demonstrates strong resistance to soybean rust and outstanding agronomic performance. The variety yields between   3-3.5 tons per hectare and matures in approximately three months. Maksoy 7N is expected to enhance national soybean productivity, increase smallholder farmer incomes, and strengthen Uganda’s soybean value chain.

Maksoy 7N joins six previously released high-yielding varieties (Maksoy 1N–6N). Impact studies by the Vegetable Oil Development Project (VODP) reveal that 93% of Ugandan soybean farmers plant Maksoy soybean varieties.

Appreciation to the partners

Prof. Tukamuhabwa expressed gratitude to the local and international development partners for their invaluable support to the project. These partners include the Ministry of Agriculture, Animal Industry and Fisheries (MAAIF), the National Oil Seeds Project(NOSP) and the International Fund for Agricultural Development (IFAD) who funded the research. Other research partners include the National Agricultural Research Organization (NARO), the Regional Universities Forum for Capacity Building in Agriculture (RUFORUM), Integrated Seed and Sector Development Uganda (ISSD Uganda), Soybean Africa Ltd, Makerere University Animal Science Laboratory, Soybean Innovation Lab, International Institute of Tropical Agriculture (IITA), and the host farmers who participated in the on-farm trials.

He also appreciated the Makerere University administration for the support extended to MAKCSID.

Honoring the Research Team

Addressing the meeting, Dr. Kikafunda, Chair of the National Variety Release Committee, praised the research team for their exceptional achievements and steadfast dedication to enhancing the nation’s food security. He emphasized the importance of their work in driving agricultural innovation and urged them to prioritize the rapid multiplication and widespread distribution of the new varieties, ensuring they reach the farmers and contribute to increased productivity and improved livelihoods across the country.

In her remarks, Dr. Mildred Ochwo Ssemakula, Head of the Department of Crop Science and Horticulture at the College of Agricultural and Environmental Sciences (CAES), Makerere University, and member of the National Variety Release Committee, lauded the team for their commitment in developing the new variety, MakSoy 7N. “This is the result of over eight years of dedicated effort. The previous variety, MakSoy 6N, was released in 2017. I deeply appreciate the team’s dedication to field activities. I also commend the former Principal of CAES, Prof. Bashaasha, for his contribution in making the MakCSID a reality, and the current Principal, Prof. Gorettie Nabanoga, for her continued support to the Centre.”

Dr. Ochwo further recognized the pivotal role of Makerere University, particularly CAES, in training critical human resources for the country, noting that most innovators and personnel in key agricultural organizations are graduates of CAES.

Approval of the Sweet Potato and Sorghum Varieties from NARO and NASECO

At the same event, the Committee approved three purple-fleshed sweet potato varieties – NAROSPOT 8P, 9P, and 10P – developed by the National Agricultural Research Organization (NARO). These varieties are credited for their high yields, strong disease resistance, and abundant provitamin A content. With a short growing period of just three to four months, these sweet potatoes allow farmers to achieve multiple harvests annually, boosting both productivity and profitability.

The committee also approved two high-yielding sorghum hybrid varieties, NS1 (Tongo) and NS5 (Tara), from NASECO (1996) (U) Ltd. These varieties are versatile, suitable not only for food consumption but also for livestock feed, bioethanol production, and brewing. Early reports indicate strong adoption rates among farmers, which is expected to reduce dependence on imported hybrid seeds and strengthen the local agricultural seed industry.

Growing up in Nkonge Village, Kyampisi Sub County in Mukono District, Esther Ziribaggwa learned early the meaning of resilience.

Born to Mr. Musisi Godfrey, a farmer, and Ms. Babirye Resty, a market vendor in Seeta, Mukono District, her journey from humble beginnings to becoming Makerere University’s top-performing student in the Sciences is a testament to her determination, hard work, and unwavering faith. She attained a CGPA of 4.77 in the Bachelor of Agricultural and Rural Innovation, a programme taught at the College of Agricultural and Environmental Sciences (CAES). She will be graduating from Makerere University on 24^th February 2026, the first day of the 76^th graduation ceremony.

Educational Journey and Navigating the Financial Hurdles to remain in School 

Ziribaggwa’s journey to academic excellence has not been smooth. But her parents’ sacrifices laid the foundation for her dreams, even as life presented relentless challenges.

She began her education at Frobel Day and Boarding Primary School and later joined Seeta Boarding Primary School, where she excelled with 9 aggregates in her Primary Leaving Examinations. However, the transition to secondary school presented challenges that tested her resolve.

She joined Mpoma Royal College in Mukono District alongside her sister, who had scored 12 aggregates. Shortly after starting Senior One, their father fell seriously ill, requiring an intestinal surgery, and could not continue to work. With the family unable to pay school fees, both sisters dropped out for a year. It was only through the compassion of the school bursar and the then Head Teacher, Ms. Namazzi Connie, who reduced their fees from 800,000 to 380,000 Uganda Shillings, that Ziribaggwa and her sister were able to return. “The year out of school was a huge setback,” she recalls, “but I focused on catching up. I knew I couldn’t waste this second chance.” Her perseverance paid off. Despite the lost year, she completed her O’ Level with 25 aggregates in eight subjects.

Her A’ Level years were marked by similar challenges. Due to financial constraints, Ziribaggwa attended three different schools. She initially enrolled at Seat of Wisdom Boarding School in Kayunga but was forced to leave when her family could no longer afford the fees. At the time, her father, the family’s sole breadwinner, had undergone a second operation and was unable to work. Her mother, a market vendor, stepped in to support her education and transferred her to Paul Mukasa Day and Boarding Secondary School in Mukono District as a day student. However, the long daily commute was exhausting, leading to a final transfer to Godmark High School in Mukono District where she completed her A’ Level in 2019 with 15 points in Geography, Economics, Agriculture, and Subsidiary Mathematics.

 After completing secondary school, Ziribaggwa waited two years before joining university due to financial constraints. Although she had been admitted under the private sponsorship scheme to pursue a Bachelor of Statistics, she was unable to raise the required tuition. Following the outbreak of COVID-19 and the subsequent lockdown, an opportunity arose for her to obtain government sponsorship. At the time, there were no Senior Six leavers, prompting Makerere University to invite applications from candidates who had completed Senior Six within a specified period. The cut-off points across programmes were lowered, enabling her to secure government sponsorship to pursue a Bachelor of Agricultural and Rural Innovation.

Appreciation

She is deeply grateful to the Almighty, her parents, and everyone who supported her educational journey. She is specifically thankful to the Government of Uganda for sponsoring her university education, and to Ms. Namazzi Connie, her O-Level Head Teacher, for subsidizing her school fees. She is also grateful to all her lecturers at CAES and Jesus is King Ministry under the Makerere University Christian Union.

Message of Resilience to Fellow Students

To the students navigating similar challenges, Ziribaggwa shares a message of encouragement. “Never let your situation break you. There’s always going to be challenges, sometimes pushing you to what feels like a point of no return. But those moments should not define your future – they are a test of your resilience. Strive to outgrow them and become a better person, even when the journey feels impossible.”

Career and Aspirations

Ziribaggwa currently works in the extension division of Slow Food Uganda, an agricultural organization based in Mukono District, where her work focuses on women and youth. Although her dream was to become a medical doctor, her love for agriculture has grown over time and does not regret taking on this path. She aspires to become a Senior Agricultural Officer in the country, with the goal of improving farming conditions, particularly in the rural communities. Growing up in a farming community exposed her to many challenges faced by farmers, including unpredictable weather conditions that necessitate irrigation support, and improper use of agrochemical inputs, which pose risks to both soil quality and human health.

Ziribaggwa hopes to pursue further studies in crop and soil science. She draws inspiration from exemplary leaders like Hon. Rebecca Kadaga, former Speaker of the Parliament of Uganda, and First Deputy Prime Minister and Minister for East African Community Affairs. “I have always admired her for being hardworking, resilient, and eloquent,” she says, seeking to emulate these qualities in her own journey.
