From Waste to Riches: How to Make Money from Mushrooms
In Uganda's thriving urban centers like Kampala and Mukono, oyster mushroom farming is emerging as a transformative business for aspiring entrepreneurs. This venture uniquely combines environmental sustainability with economic opportunity, making it attractive for those seeking to create value from everyday waste.
By repurposing agricultural by-products, such as cotton husks, into mushroom-growing substrate, this farming method not only addresses waste management challenges but also opens the door to a highly profitable agricultural niche. Cotton husks, typically considered agricultural residue, are abundant in Uganda, inexpensive, and rich in the nutrients mushrooms require. These qualities make them an ideal foundation for cultivating oyster mushrooms, which are popular in markets due to their versatility, nutritional value, and ease of cooking.
The beauty of this business lies in its accessibility. Unlike traditional farming, mushroom cultivation doesn’t require expansive land or heavy machinery. Urban dwellers can start on a small scale, using a spare room, shed, or even a balcony as a growing space. The startup costs are modest, and the materials required—mushroom spawn, cotton husks, and basic tools—are readily available. With a little effort and dedication, small-scale growers can harvest their first crop in just a few weeks, turning waste into a source of income while contributing to a greener environment.
For many urban Ugandans, oyster mushroom farming is more than just a side hustle—it’s a way to tap into a growing market while championing sustainability. By leveraging agricultural waste, they’re not just earning money but also helping to reduce environmental strain, making this venture a true example of turning waste into wealth
The ultimate goal of farming is not the growing of crops, but the cultivation and perfection of human beings.

The Process: Turning Cotton Husks into Gold
Cotton husks, widely available in Uganda, are an excellent substrate for growing oyster mushrooms. These husks are not only cost-effective but also provide the nutrients needed for mushrooms to thrive. After collection, the husks undergo pasteurization to eliminate pathogens and prepare the substrate for spawning. Once inoculated with mushroom spores, the substrate is packed into small bags and monitored for growth. Within 3–4 weeks, the first harvest is ready, with each bag producing multiple flushes of mushrooms over its lifecycle.
Costs and Startup Requirements
Starting a small-scale mushroom farm in Uganda requires an initial investment of about UGX 3,000 per substrate bag, as reported by New Vision. For a farm with 100 bags, the estimated startup cost is around UGX 300,000–500,000. This covers the purchase of substrate materials, mushroom spawns, and basic equipment such as racks and watering cans. For urban farmers, spaces as small as a single room can accommodate a mushroom farm, making it ideal for areas with limited space.
Revenue Potential
Oyster mushrooms have a high market demand due to their nutritional and medicinal benefits. A kilogram of fresh mushrooms sells for UGX 10,000–15,000 in Kampala's markets, while dried mushrooms fetch even higher prices. With each substrate bag yielding about 2 kilograms of mushrooms, a small farm with 100 bags can produce up to 200 kilograms per cycle, generating UGX 2,000,000–3,000,000 in revenue.
Environmental and Social Impact
Apart from being a profitable venture, mushroom farming contributes to environmental conservation by diverting agricultural waste like cotton husks from landfills. This aligns with sustainability goals and provides an avenue for job creation and poverty alleviation in urban communities.
Scaling Up
As profits grow, farmers can reinvest to expand their operations. Larger farms can include processing units for drying mushrooms, packaging facilities, and direct marketing to supermarkets and export markets. With an estimated return on investment of 300%, oyster mushroom farming is a viable and sustainable business for Ugandan entrepreneurs.
Conclusion
Oyster mushroom farming is a shining example of how urban Ugandans can turn waste into wealth. With cotton husks as a substrate, minimal capital requirements, and high revenue potential, this business is perfect for aspiring farmers in Kampala and Mukono. By starting small and scaling up, anyone can reap the financial and environmental benefits of this thriving sector.
