Mak Researchers in Drive to Improve Waste Management in Uganda
****Through a project titled, “Adding value to agro/bio-waste through integrating technologies to enhance sustainable agro-process waste management in Uganda”, the researcher led by Dr Joseph Kyambadde from the Department of Biochemistry and Sports Science, have proposed a number of technologies that can be used to avert the challenge of poor waste management in the country.
Background
Majority of industries in the country such as dairies, abattoirs, breweries, distilleries, and tanneries are engaged in agro-processing. Such industrial processing often leads to the discharge of large quantities of organic-rich wastewater, disease-causing micro-organisms, and greenhouse gas emissions, if poorly treated or managed. While the regulatory body, the National Environment Management Authority (NEMA) requires that all industries should efficiently treat their effluent to meet discharge standards, waste treatment technology market surveys that were carried out in the major industrial cities of Kampala, Jinja, Masaka and Mbarara in 2018 showed that most agro-process industries do not treat their wastewater. Furthermore, very few have in there effluent treatment management, resource recovery processes such as bio-digesters for recovering biogas and nutrient-rich bio-slurry. The industries that attempt to treat their effluent mainly use conventional systems, such as settling tanks and lagoons that do not efficiently remove all waste components. Additionally, industries require energy for their operations, but many use non-renewable sources, such as wood fuel, contributing to deforestation and greenhouse gas emissions. Consequently, the agro-process industries pollute the environment, contaminate drinking water sources, and pathogens from their wastes contribute to cases of diarrheal diseases. The agro-processing sector urgently needs technology solutions that would meet national environment regulatory requirements at affordable costs, but also incorporate resource recovery and reuse to protect the environment and also enhance their profit margins. However, many industries lack cost-effective technologies to convert their wastes into biogas or other useful by-products such as slurry for use as manure/bio-fertilizers. The industries also lack expertise to design and operate appropriate waste treatment technologies.
Addressing the challenge of poor waste management
Agro/bio wastes are organic-rich, hence can be biodegraded using appropriately designed integrated technologies. These methods offer the options for meeting national discharge standards, reuse of treated effluent, and recovery of useful by-products. A study conducted by researchers from the College of Natural Sciences (CoNAS), Makerere University in collaboration with partners in the waste management sector proposes a number of technologies that can be deployed to effectively address the challenge of waste in the country. These include; anaerobic-aerobic digesters, sludge drying beds, constructed wetlands, and duckweed growing units.
Through their project titled “Adding value to agro/bio-waste through integrating technologies to enhance sustainable agro-process waste management in Uganda”, the researchers led by Dr Joseph Kyambadde from the Department of Biochemistry and Sports Science at Makerere made several recommendations towards waste management in the country. The researchers called for integration of aspects of the technology, encompassing wastes-to-energy courses/topics in the curricula of programmes like biochemistry, industrial chemistry, and environmental sciences at universities. This would enable training of scientists who would in turn foster adoption and promotion of the developed technologies in different industries. They also emphasized the need to promote investment in technologies that can be used to convert waste into useful by-products like biogas, bio-fertilizers and protein-additives, and to raise awareness about the importance of waste treatment technologies amongst private-public actors, managers/business owners of agro-processing industries, as well as government line ministries/agencies, and development partners.
Supported by the Government of Uganda through the Makerere University Research and Innovations Fund (Mak-RIF), the overall objective of the project was to contribute to climate change mitigation, environmental sustainability, and agricultural development through integrated waste management systems. Under the project, the research team developed nutrient-rich fertilizer and animal feeds, and supported the production of biogas and electricity. Other members on the project included; Dr. Robinson Odong (Co-Principal Investigator), Dr. Gertrude Muwanga (Economist), Eng. Charles Ddungu (Civil Works), Eng. Edward Kalule (Electricals), Mr. Bright Twesigye (Research Assistant), Mr. Sendi (Field Assistant), Mr. Kuman (Field Assistant), and CATDA (Project Host).
Research dissemination seminar
On 23rd January 2024, the project team held a seminar at Ridar Hotel, Mukono District to present their research findings/outputs to key stakeholders in the waste management sector such as industry, academia, and policy makers, and also receive feedback. At the meeting, the project PI, Dr. Joseph Kyambadde decried the high level of poor waste disposal in the country. Highlighting the support extended to City Abattoir Traders Development Association (CATDA), Dr Kyambadde said many industries were directly disposing effluent into water sources, posing a number health, environmental and economic risks. “Investing in waste treatment technologies would avert the risks, but also support the recovery of useful byproducts such as nutrient-rich slurry or biogas.” As one of the achievements registered, the project supported the construction of a wastewater treatment plant at Kampala City Abattoir. According Mr. David Mutebi, the PRO of Kampala City Abattoirs Hides and Skin Traders’ SACCO, before Makerere supported the construction of the plant, effluent used to be discharged in Nakivubo Channel, posing several health and environmental risks. Dr Kyambadde appreciated the Government for supporting the project which is envisaged to minimize poor waste disposal throughout the country.
As part of the strategies for sustainable agro-process waste management in the country, participants advocated for a comprehensive policy, a waste management fund, and incentives for investment in waste management technologies. They also called for a comprehensive curriculum for waste management, and a market development plan for waste products.
In his remarks, the Deputy Principal of CoNAS, Prof. Juma Kasozi appreciated the Government of Uganda for the support extended to the project. “Poor waste disposal is one of Uganda’s biggest challenges. I commend the research team for venturing into research that directly addresses the country’s development problems.” He called for increased investment to support initiatives aimed at managing waste from industries and other places.
A nationwide study led by Prof. Fredrick Jones Muyodi has revealed multiple factors contributing to poor performance in Biology in Uganda’s national examinations, with the Northern and Eastern regions being the most affected. The study highlights significant gaps in practical learning, digital access, and teaching methods, underscoring an urgent need for educational reforms.
Factors that prompted the study
Launched in 2023, the study was undertaken in response to growing concerns over the long-term decline in Biology performance in the Uganda Advanced Certificate of Education (UACE) examinations.
An earlier analysis conducted by the School of Biosciences at the College of Natural Sciences (CONAS), Makerere University, revealed that since the late 1970s, performance in Biology at the UACE level had consistently fallen below expectations. Over time, the situation worsened, as reflected in the annual examination results released by the Uganda National Examinations Board (UNEB).
In 2018, for example, only one student out of 13,061 candidates scored an “A” in Biology, while just 38% scored at least an “E”. Although 2019 saw a slight increase, overall results remained far below national standards, a trend that persisted into the post-COVID-19 era.
Poor performance in Biology has serious implications, as the subject underpins 70–100% of academic and research work across the College of Natural Sciences, the College of Health Sciences (CHS), the College of Veterinary Medicine, Animal Resources and Biosecurity (COVAB), and the College of Agricultural and Environmental Sciences (CAES). Weak results affect student progression and threaten Uganda’s life sciences ecosystem, impacting key sectors and government ministries.
In response, Makerere University, through the School of Biosciences at CoNAS in collaboration with the College of Education and External Studies (CEES), launched a study to investigate and address the problem. Funded by the University’s Research and Innovations Fund (MakRIF), the study examined teacher qualifications, curriculum depth, laboratory infrastructure, and student attitudes towards the subject.
Dissemination of the Study Findings
The project team presented their findings to stakeholders at a workshop held on 19th March 2026 at Makerere University. The event was attended by the Commissioner for Secondary Education at the Ministry of Education and Sports, Mrs. Juliet Atuhairwe Muzoora, alongside senior leaders from Makerere University.
Factors undermining performance in Biology
Guided by the socio-ecological model, the project team interviewed 5,000 participants, including teachers, students, parents, school administrators, and curriculum experts, across 100 districts nationwide. Key challenges identified include:
- Inadequate practical learning – Many schools lack functional laboratories, leaving students unable to connect concepts to real-life applications.
- Limited digital access – Poor internet connectivity and lack of digital learning tools hinder modern science education.
- Ineffective teaching methods – Overreliance on lectures weakens conceptual understanding.
- Gender disparities – Lower confidence and limited participation of female students in practical work.
- Negative community perceptions – Low motivation resulting from societal attitudes toward Biology.
Recommendations for Improvement
Despite a notable improvement in the 2025 Uganda Advanced Certificate of Education (UACE) examinations, the project team recommends a series of strategic interventions:
- Expansion of practical learning through fieldwork and project-based activities, with government support to fund hands-on initiatives.
- Investing in digital infrastructure, prioritizing internet access and online resources for underserved schools.
- Upgrading laboratories with modern equipment and increasing technical support to create conducive learning environments.
- Strengthening teacher development through continuous professional development programs promoting inquiry-based teaching.
- Aligning curriculum and assessments by fostering collaboration between the NCDC and UNEB to ensure coherence between instruction and exams.
- Enhancing student engagement through mentorship programs, academic clubs, and career guidance initiatives.
- Promoting gender equity in science education through targeted interventions.
The project team emphasizes that these interventions are essential for developing a generation of Biology students well-equipped to meet the demands of higher education and scientific careers. They advocate for coordinated action among government agencies, schools, and communities to reverse current trends and strengthen science education nationwide.
To further support efforts to improve performance in Biology, the team is seeking additional funding to pilot interventions in the most affected regions, particularly Northern and Eastern Uganda, and to establish a monitoring and evaluation framework to track progress and ensure lasting impact.

Makerere University Researchers Awarded UCIF Grant to Tackle Maize Contamination with Innovative Plant-Based Fungicide
In a significant stride towards ensuring food safety and agricultural resilience, a team of researchers from Makerere University has been awarded the prestigious Uganda Climate Innovation Fund (UCIF) to support the development of a groundbreaking solution to maize contamination.
Maize, a staple food for millions of Ugandans, has long been threatened by Aspergillus fungi, which produce aflatoxins, highly toxic compounds that pose serious risks to human health, livestock, and the nation’s agricultural productivity. Recognizing the urgency of this challenge, the research team from the Department of Plant Sciences, Microbiology, and Biotechnology at the College of Natural Sciences (CoNAS), Makerere University, is pioneering the development of a plant-based organic fungicide aimed at significantly reducing Aspergillus growth and aflatoxin contamination in maize.
The initiative is spearheaded by Dr. Abubakar Sadik Mustafa (Principal Investigator), with major contributions from co-innovators Dr. Jamilu E. Ssenku, Dr. Patience Tugume, Mr. Frank Kalungi, and Mr. John Okello. The team officially received the UCIF award on 26 February 2026 at an event held at Kampala Serena Hotel.
“This recognition underscores the importance of locally-driven scientific innovation in safeguarding our food systems,” said Dr. Mustafa upon receiving the award. “Our goal is to deliver an environmentally friendly solution that not only protects maize but also contributes to public health and supports sustainable livelihoods for smallholder farmers.”
The UCIF grant, funded by the UK Foreign, Commonwealth & Development Office (FCDO) under the Climate Smart Jobs initiative, is implemented by Palladium in collaboration with Stanbic Bank, Swissconnect, and CABI. The programme seeks to advance solutions that address the dual challenges of climate change and economic development by supporting innovations that foster sustainable agricultural practices, reduce environmental risks, and create climate-smart employment opportunities.
This breakthrough aligns closely with the global Sustainable Development Goals (SDGs), particularly those targeting good health and well-being (SDG 3), zero hunger (SDG 2), and climate action (SDG 13). By developing a natural, plant-based fungicide, the Makerere University team hopes to offer a scalable solution that mitigates food contamination risks while promoting environmentally sustainable farming practices across Uganda.
