Mak-CAES, UNBS Launch Edible Insect Products & Standards
Edible insects have the potential to fill the nutrition and income gaps in Uganda and Kenya. They are rich in protein and cheaper to manage. However, edible insect value chains are under-developed yet the demand is high. Business enterprises for rearing and processing quality insect food products do not exist and the business potential has not been evaluated.
Through a project titled INSBIZ – “INSect-based agriBIZiness for Sustainable grasshopper and cricket production and processing for food in Kenya in Uganda” researchers from the Department of Food Technology and Nutrition, College of Agricultural and Environmental Sciences (CAES), Makerere University in collaboration with partners from the International Centre of Insect Physiology and Ecology (icipe) set out to improve the profitability and nutritional benefits of edible insects.
Objectives of the project
The development objective of the project was to contribute to improved food and nutritional security, job creation and income generation, and reduction of the gender gap for the most vulnerable groups in East Africa in general and specifically in Kenya and Uganda through edible insects production and processing. Specific objectives included; (1) assessing the market size and testing the market performance of insect-based foods; (2) adapting and piloting of mass rearing protocols for crickets and grasshoppers; (3) developing, characterizing and commercializing insect-enriched food products; and (4) creating a favourable enabling environment for insect-based food through policy/standards, advocacy and awareness creation.
The three-year project funded by the Swedish International Development Agency (SIDA) through the BioInnovate Africa Programme Phase II was headed by Dr Dorothy Nakimbugwe, an Associate Professor in the Department of Food Technology and Nutrition at CAES. Other members on the project included Dr. Geoffrey Ssepuuya from the same department, and Dr. Jackline Bonabana-Wabbi from the Department of Agribusiness and Natural Resource Economics.
Project closing meeting
During the project closing meeting held in the School of Food Technology, Nutrition and Bio-Engineering Conference Hall on 28th March 2022, Makerere University together with Uganda National Bureau of Standards (UNBS) launched edible insect products and standards for the enterprise. The event was presided over by Makerere University Vice Chancellor, Prof. Barnabas Nawangwe and Uganda National Bureau of Standards Executive Director, Mr. David Livingstone Ebiru. It was witnessed by the Principal of CAES, Dr Gorettie N. Nabanoga; the Commissioner in charge of Entomology at the Ministry of Agriculture, Animal Industry and Fisheries, Mr. Gidudu Masaba Ambrose; and representatives from icipe led by Dr. Chrysantus Mbi Tanga.
The products launched included shelf-stable, safe and well packaged grasshopper products, cricket enriched flours, snacks, and cookies enriched with crickets.
Project outcomes
Addressing participants, Dr Nakimbugwe said the products would largely reduce nutritional challenges. “The majority of our people are not able to improve their diets because the foods that are high in protein, vitamins and minerals like chicken, beef and fish are expensive. We turned to insects because they address some of those problems. They are more nutritious than the conventional animal proteins like chicken, beef and fish. In addition, they take a shorter time to grow. Crickets grow in a matter of weeks compared to the other livestock. They can be harvested within 4 to 7 weeks. They also have a high feed conversion. The amount of feed you need to produce 1kg of insect is only about one and half kilogrammes. When it comes to the producing 1 kg of chicken, the amount of feed increases to about 5 kgs. If you are to produce 1 kg of beef, the amount of feed you need is 50kgs. The insects convert feed rapidly and efficiently and produce protein faster and of the same quality. They also require less space for rearing and present an opportunity to close the food and nutrition gap especially around proteins, vitamins and minerals,” she explained.
According to Dr Nakimbugwe, the project also sought to formalize the sector to make it more profitable. “For a long time, we have not had a certified product on the market because the Uganda National Bureau of Standards did not have a standard. The sector has been very informal. Insects are sold on streets and not controlled. In this project, we wanted to improve that situation. Together with the UNBS, we developed a standard for Uganda which was approved and is now available for use. For the first time you will be able to find certified insect products on the Ugandan market,” she noted.
The project also aimed mitigate the effects of climate change and greenhouse emissions that are high for animals and much lower for insects.
Other contributions included building capacity for research in this field. “The research in insects for food and feed is fairly new compared to other fields so we needed a lot of capacity development. The project was able to train the farmers and harvesters on handling of insects. We also trained students from PhDs, to MAs, undergraduates, fellows and technicians. This was necessary to sustain the research and development of this fairly noble field.”
Under the project, the researchers developed a compound feed to sustain large scale production of the insects. “If you are going to do commercial production, it is important that you have a standardized feed. In this development, we were very careful to exclude input that are also human food like silver fish and soy. Most of the feed in Uganda is in competition with the human food chain. In the project we were careful to avoid that. We formulated feed using the Black soldier fly larvae,” she explained.
Other outputs included strengthened edible insect value chains – cricket farmers linked to markets; large scale production, processing and marketing of cricket and grasshopper products; approved insect based food standards in Kenya and Uganda; improved grasshopper trapping method (cost-effective, sustainable and safer); more sustainable cricket rearing – using developed feed and container prototypes; and improved food and nutritional security through increased diversity of available nutritious and safe edible insect foods. All the products developed have shelf-life of over 6 months. For the grasshopper product, this implies all-year availability to consumers.
The project also contributed to the improvement of consumer health and safety through consumption of UNBS (and KEBS)-certified insect food products; increased incomes as a result of lower post-harvest losses for cricket farmers and grasshopper harvesters through use of improved post-harvesting techniques to maintain quality and safety; increased jobs creation and job security through improved capacity of young researchers, technicians and actors along the edible insects’ value chains; higher profile of and support for insect foods due to increased public awareness of their nutritional and commercial importance through various programmes.
During the event, a cricket farmer from Masaka shared her experience with the enterprise. She noted that with support from the project, cricket rearing had greatly transformed her life and is now able to pay fees for her children. The project supports over 50 cricket farmers in Masaka.
Remarks by the Vice Chancellor
In his remarks, Makerere University Vice Chancellor, Prof. Barnabas Nawangwe applauded the researchers noting that the project would largely address challenges of food insecurity in the country. “Makerere University researchers are taking the issue of food security seriously. In Africa, the biggest challenge we have is feeding the growing population. The traditional foods are not expanding in volume and some are actually disappearing yet we have this abundancy of what you can call the animal world. There are insects that we have traditionally eaten but these are seasonal. There are also insects which we assume we should not eat but are highly nutritious and eaten by people all over the world. Researching into ways of making their products more attractive will largely increase their consumption and boost food security,” he explained. He acknowledged the efforts of the researchers towards transforming Makerere into a research-led University as per the 2020-2030 Strategic Plan.
Speaking on the need to move the country to middle income status, the Vice Chancellor urged the researchers to transform the innovations into business enterprises. “We need to move towards setting up companies that will address challenges of unemployment but also boost our economy. With these great ideas, you can become billionaires and less dependent on salary,” he advised. He cautioned researchers to work towards patenting their products.
The Vice Chancellor appreciated SIDA and BioInnovate Africa for the support extended to the project. He also thanked the Government of Uganda for supporting research activities at the University. He urged researchers to continue engaging the government and private sector in projects, noting that research is more impactful when they work together.
Remarks from CAES Leadership
The Principal of CAES, Dr Gorettie N. Nabanoga applauded the project team for what she described as cutting-edge research that will greatly address challenges of food insecurity, malnutrition and improve food safety. “You have made CAES and Makerere proud with this level of success registered from the project,” she said.
Dr Nabanoga appreciated the development partners and the Government of Uganda for the continued support towards research at Makerere. She also appreciated the Vice Chancellor for the untiring support towards CAES activities.
In their remarks, the Dean of the School of Food Technology, Nutrition and Bio-Engineering, Dr Abel Atukwase and the Head Department of Food Technology and Nutrition, Dr Ivan Muzira Mukisa congratulated the research team upon the successes registered. They also appreciated the project partners and funders for the support extended to various programmes at CAES.
The Executive Director of Ugandan National Bureau of Standards, Mr. David Livingstone Ebiru urged the research team to extensively disseminate and rollout the project to other parts of the country. He called for innovative measures of ensuring sustainability of the projects when donor funding stops.

*****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
- Weak fecal sludge management systems: Existing systems, particularly in refugee settlements, are inadequate.
- Public health risks: Improper sludge handling continues to threaten health – only 44% of fecal sludge is safely managed.
- Limited technical capacity: Practitioners need more training in safe handling and reuse technologies.
- Low adoption of resource recovery: Sludge-to-product innovations are underutilized.
- Environmental pollution: Untreated sludge contaminates soil, water, and surrounding ecosystems.
- Poor integration with agriculture: Opportunities for nutrient recycling are not fully exploited.
- Inadequate equipment: PPE, emptying tools, and treatment facilities are scarce.
- Low composting standards in Uganda: Composting often follows non-scientific methods.
- Behavioral and hygiene gaps: Handwashing and proper waste disposal practices remain weak.
- Underdeveloped waste-based value chains: Compost, briquettes, and fertilizers are not economically leveraged.
- High reliance on on-site sanitation: Sewer network coverage is below 10% in Greater Kampala.
- Insufficient emptying and collection services: Services are limited and costly.
- Limited private sector engagement: Public investment and private participation are inadequate.
- Treatment capacity and cost recovery challenges: Facilities are strained and revenue mechanisms weak.
- Low willingness or ability to pay: Users are reluctant or unable to afford improved services.
- Negative perceptions of fecal sludge products: Public attitudes hinder adoption.
- Regulatory and equity barriers: Awareness is limited, regulations are burdensome, and access is unequal.
Way Forward
Effective waste management is essential for public health, yet remains a significant challenge in Uganda, with few households able to empty their on-site sanitation facilities due to high costs. Experts emphasize the need for increased investment and prioritization of operator safety. Rigorous safety protocols and training are critical to safeguarding workers and ensuring sustainable operations.
Remarks by the CAES Leadership
On behalf of the Principal of CAES, Dr. Mildred Ochwo Ssemakula underscored Uganda’s immense potential to benefit from effective fecal sludge and solid waste management. “In an agriculture-dependent country, converting waste into organic fertilizer and other resources can significantly enhance productivity and generate substantial economic benefits. At the CAES, we are proud to collaborate and support initiatives like CPUg through innovative research and capacity-building programmes that directly address Uganda’s environmental challenges. I extend my sincere gratitude to the researchers and partners for their unwavering commitment to advancing research and environmental management. Makerere University highly values these collaborations, and together, we form a powerful coalition driving positive change in Uganda’s development.”
The CPUg project has contributed to capacity-building by training five PhD students, three from Makerere University and two from Vienna University of Technology, as well as three MSc students from Makerere University. The results are expected to improve knowledge in waste management and strengthen stakeholder capacity across the waste management value chain.
