In the coastal village of Bwejuu, Zanzibar, mornings once began with the thick smoke of firewood drifting through homes. For Mama Salma, a mother of three, cooking meant coughing fits, burning eyes, and long hours spent collecting fuel from shrinking forests.

“Some days I walked for hours just to find wood,” she recalls. “I was tired before I even started cooking.”

Today, Salma turns a small valve in her kitchen, and a clean blue flame appears, powered entirely by her household’s KyoGreen biogas system, which converts organic waste into safe, renewable cooking energy.

“There is no smoke now,” she smiles. “My children can sit with me while I cook.”

The benefits ripple through the community. Indoor air pollution has dropped dramatically. Families save money that once went to charcoal. Women reclaim precious time, now used for small businesses, learning, or rest.

At the local school, a KyoGreen School Biogas System feeds over 400 students daily. Meals are cooked without smoke, fuel costs have been cut, and the nutrient-rich digestate now supports the school garden.

“This system has changed everything,” says the headteacher.

“We save money, the kitchen is clean, and our students are healthier.”

Each unit prevents tonnes of CO₂ annually and reduces pressure on Bwejuu’s fragile forests, creating a cleaner coastline and a more resilient community.

For families like Salma’s, the impact is clear:

“Life feels lighter,” she says. “The clean flame has given us clean air  and new hope.”
