David Monday Transforms Uganda's Plastic Waste into Durable Eco-Houses

In Mayembe Upper Hill, Mpigi District—about 40km from Kampala—rows of sturdy homes rise from recycled plastic bottles, a innovative response to Uganda’s mounting waste problem.

David Monday, founder of Pendeza Shelters, launched this project after losing his 10-year-old brother in 2007 floods triggered by plastic-clogged drains in Kasese. Motivated to repurpose waste, he researched techniques from Cameroon and Nepal, then built his first house in 2014 using bottles packed with soil and bound by mortar.

These structures boast remarkable durability, lasting up to 420 years when reinforced with iron bars and concrete. Walls use thousands of bottles per house, foundations rely on stones, and roofs incorporate iron sheets, car tyres, or glass. A typical two-bedroom home costs Shs18-25 million, while a recent four-bedroom double-storey in Mpigi ran Shs95 million.

Monday’s team collects bottles from Mpigi, Wakiso, and Kampala, employing 120 workers on average. Since 2014, they’ve built 64 houses in Uganda, Zimbabwe, Kenya, Nigeria, South Africa, and Congo, collecting 2.24 million bottles and training 305 youths and women, boosting their incomes by 30%.

Beneficiaries like Lilian Namatovu and Roselline Ryokot praise the homes for being cool in heat, warm in rain, termite-resistant, fireproof, and low-maintenance. They even draw tourists curious about the unique design.

Uganda grapples with waste mismanagement: 92% dispose improperly, per the 2024 census. Kampala generates 2,500 tonnes daily, collecting just half. The Kiteezi landfill collapse in 2024 killed 34, underscoring the crisis. Experts call for stronger policies, better enforcement, and youth involvement in green jobs.

Challenges persist, including public skepticism about the houses’ strength and high transport costs, but Monday’s work showcases a path to sustainability.
