According to the United Nations, one-third of the world’s food is wasted annually. The majority of fruit loss occurs during storage or right after harvest. Drying fruit prevents food waste. Drying fruit has a lot of benefits. It can decrease post-harvest waste, increase the commercial value of fruit, add jobs to the local economy, and provide great nutritional value.
Our Community Partner
We have designed an affordable drying system that attempts to optimize drying time and reduce fuel expenditure to allow our community partner, the Teso Women Development Initiative (TEWDI Uganda), to produce attractive, clean-tasting fruit at a profit. TEWDI is based in Soroti, Uganda, and has several small businesses for charcoal briquette, charcoal Makaa cookstove, and fruit drying production.
Activities Conducted
We have evaluated multiple designs from two potential fuel sources: charcoal briquettes and peanut shells. After doing a holistic analysis of different design criteria, we concluded that the charcoal-powered Makaa cookstove heat exchanger (HEX) was the best option. It uses readily available materials and has a familiar user experience. We then designed the HEX around the Makaa cookstove’s dimensions and heat output. In our design, we prioritized the maximization of radiative heat transfer and the minimization of thermodynamic losses. The HEX was then tested for its thermodynamic efficiency.
As part of the Lake Victoria Improved Water Level Management through Advanced Modelling (LIVWA) Project, newly developed tools were unveiled during a dissemination workshop hosted by the College of Engineering, Design, Art and Technology (CEDAT) on August 26th, 2026. The project seeks to develop advanced hydrological and climate models to enhance water level management in Lake Victoria, East Africa’s largest freshwater resource.
The tools were designed to integrate remote sensing and reanalysis climate datasets with advanced hydrological modeling, enabling researchers and policymakers to better predict fluctuations in water levels in the lake. By combining historical data with AI and Machine Learning forecasting, the models aim to provide actionable insights for sustainable water resource management. Click here for details
Running a side business alongside full-time employment has become an increasingly popular venture among staff. For many, it is a way to supplement income and build financial resilience. For Ms. Rebecca Talikaza, a 48-year-old custodian, it has become a pathway to transformation. Talikaza successfully balances her office responsibilities with her growing enterprise, Beckiz Bathing Sponge.
“For the years I have been running Beckiz Bathing Sponge, my side business has not affected my work. I have a support system at home, and I have learnt how to utilize my time well,” she explains.
Turning Necessity into Opportunity
Talikaza’s entrepreneurial journey began during the COVID-19 period, when schools reopened. While preparing to take her first-born son back to school, she realized he did not have a bathing sponge. A search in nearby supermarkets in Nakwero proved futile.
“When I failed to get a bathing sponge, I went back home and looked for some material I had bought earlier. I became creative and decided to knit one using skills I had acquired in primary school,” she recalls.
As she worked, a neighbor noticed her and expressed interest. “When I told her I was knitting a sponge, she asked me to make four for her,” Talikaza says. After completing the order, her neighbor paid her UGX 20,000.
That same day, a boda boda rider she had sent on an errand also requested one. “He told me instead of giving him money, I should give him a sponge. That is when it hit me—I could actually make money from this. Every home needs two or three sponges,” she says.
From Small Orders to Supermarket Shelves
Encouraged by the demand, Talikaza approached Babis Supermarket in Nakwero with her sample. She requested to supply her products after noticing the gap in the market. The manager agreed and asked her to produce two dozen sponges for distribution across five branches.
She also secured a similar opportunity with Shop Wise Supermarket in Manyangwa Village. “Both supermarkets accepted, but it took me three weeks to deliver. I had to sacrifice my sleep, sometimes working until 2:00 a.m. to meet the demand,” she says.

Her first delivery earned her UGX 54,000 per dozen, with each sponge retailing at UGX 5,000. Drawing on knowledge from her Postgraduate Diploma in Business Administration at Makerere University Business School, Talikaza realized the importance of branding and packaging. “I knew I had to register my business and package my products well because my target customers value quality,” she explains.
Improved packaging doubled the price of her sponges from UGX 5,000 to UGX 10,000. Since then, the business has steadily grown, enabling her to pay school fees and purchase land.
Challenges Along the Way
Despite her success, Talikaza faces challenges, particularly with delayed payments from supermarkets.
“Some supermarkets take long to pay, yet I need money to buy materials, so I end up using funds from other sources,” she says.
She also points to the difficulty small businesses face in meeting formal requirements. “Some supermarkets require invoices, which is challenging for small businesses like mine. Without them, we are taxed heavily,” she adds.
Advice on Managing a Side Hustle
Talikaza emphasizes discipline, sacrifice, and humility as key ingredients for success. “Never despise humble beginnings. Side businesses do not accommodate laziness. If it means working late, do so to ensure growth and profit,” she advises.
She also stresses the importance of fairness and teamwork, noting that she employs her children and a maid to help with production—and pays them weekly. To maintain professionalism, Talikaza draws a clear boundary between her job and her business.
“Your office work should not suffer because of your side hustle. I do not sell my products at the University. Those who need them can find them in supermarkets,” she says. She recommends careful time management, dedicating working hours to official duties and reserving evenings or weekends for business.
Efficiency, she adds, is critical. “I do not leave work to buy materials. I send a boda boda rider who delivers on time. He even helps monitor stock in supermarkets,” she explains. Above all, Talikaza encourages aspiring entrepreneurs to build businesses around passion and knowledge.
“Understand your business—its strengths, weaknesses, opportunities, and threats. Also know your target market to avoid being cheated,” she says.
