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.
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.
Prof. Fred Kabi from CAES supervised the students.
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.
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 Africa Climate Collaborative at Makerere University, an initiative supported by the Mastercard Foundation, has launched an inclusive Youth Skilling Program aimed at equipping young people with practical, market-driven skills to unlock business opportunities and contribute to climate resilience.
The Program will begin with a pilot of fifty (50) youth selected from Lwengo, Rakai and Yumbe districts, forming the first group of a planned 500 young people to be trained over the eight-year implementation period. The initiative targets youth who have completed at least Senior Four or its equivalent but have not enrolled for or completed university education.
For the first group, the youth will receive intensive hands-on training across the poultry value chain, enabling participants to develop climate-smart enterprises, create employment opportunities and strengthen their livelihoods.
The Program Director of the Africa Climate Collaborative, Prof. Gorettie Nabanoga, indicated that the Skilling Program was designed in response to the challenges faced by thousands of young people who are not in employment, formal education or vocational training (NEET).
“We realised that there are several young people who never got an opportunity to attend university or pursue higher education, yet they constitute the majority of our population. We are intentionally creating pathways that enable them to acquire practical skills, participate meaningfully in the economy and secure dignified employment,” Prof. Nabanoga said.
Prof. Gorettie Nabanoga
Applications for the first group under youth skilling program are now open to eligible youth residing in either Lwengo Sub-County in Lwengo district, Ddwaniro Sub-County in Rakai district, Zone 5 of the Bidibidi Refugee Settlement, or Ariwa Sub-County in Yumbe District.
Prof. Gorettie Nabanoga explained that the Africa Climate Collaborative deliberately selected these locations because they are among the most vulnerable to the impacts of climate change.
The programme prioritises districts within Uganda’s agropastoral landscape. She further indicated that the Program is aimed at nurturing young people who will serve as catalysts for enterprise development within their communities.
“The training will equip participants with practical skills that enable them to innovate around climate-related challenges while protecting the environment. Ultimately, they will generate income, improve their livelihoods and become catalysts for local economic transformation.” she said.
Why Poultry?
The Africa Climate Collaborative selected the poultry value chain as the entry point for the pilot because it offers diverse opportunities for entrepreneurship, innovation and employment.
According to Prof. Nabanoga, trainees will specialise in different components of the value chain, including feed production, hatchery management, poultry production, poultry product value addition and poultry waste management.
“The poultry sector offers numerous opportunities for innovation. By developing expertise across different components of the value chain, these young people will collectively strengthen the entire poultry ecosystem.”
Environmental sustainability remains central to the program. Participants will be introduced to climate-smart production practices, resource efficiency and innovative approaches to poultry waste management that minimise environmental impacts while improving productivity.
Program participants are expected to become community resource persons who will transfer the acquired knowledge and skills to other young people.
“These young people will become trainers of trainers. When they return to their communities, they will establish enterprises and mentor others, creating a critical mass of youth engaged in climate-smart businesses.”She noted.
District Leaders and Experts Welcome the Initiative
District leaders have welcomed the program, describing it as a timely intervention for addressing youth unemployment.
Francis Bwowe, Senior Agricultural Officer for Rakai District, described the intervention as timely and transformative.
He noted that the closure of Primary Teachers’ Colleges and the increasing costs of post-secondary education have left many youths without viable alternatives.
“Many young people who complete Senior Four have nowhere to go. Therefore, a program that equips them with practical skills to start their own businesses is extremely important. We believe it will help them become self-reliant and earn a living,” he explained.
Community leaders also expressed optimism about the program’s potential to transform livelihoods.
Mr. George Kizito, LCII Chairperson of Kalere Parish in Rakai District, said unemployment remains one of the greatest challenges facing young people.
“The opportunities exist, but many young people lack the capacity and confidence to create jobs for themselves. In our community, people involved in poultry farming are earning good money, but many youths simply watch because they do not know where to start from,” he said.
The program has also received positive reactions from technical experts. Responding through one of the Africa Climate Collaborative’s social media platforms, Ms. Nehwera Eufemia, a specialist in animal feeds, commended the decision to prioritise feed production.
“Feed accounts for nearly 70 percent of poultry production costs and is the single most important factor influencing profitability. Strengthening skills in feed production provides a strong foundation for improving productivity and sustainability across the entire poultry value chain” she observed.
Ms. Eufemia encouraged eligible young Ugandans to apply and take advantage of the opportunity.
