About Us
Sian Biogas
Born from the heart of Kericho County in 2023, SIAN Biogas Ltd. is more than just a biogas digester company – we’re a community-focused enterprise committed to empowering local communities through renewable, clean energy solutions.
Driven by a deep connection to our community and a growing concern for the environment, our founders witnessed firsthand the challenges posed by traditional waste management practices and the lack of access to clean, reliable energy. We saw families struggling with respiratory illnesses from burning waste, farmers facing rising fertilizer costs, and communities yearning for a more sustainable future.
Our biogas solutions directly address these concerns. By capturing organic waste and converting it into clean energy, we offer a sustainable alternative to fossil fuels, reducing greenhouse gas emissions and contributing to SDG 13.
Additionally, biogas technology promotes access to clean and reliable energy in developing regions, aligning with SDG 7. This two-pronged approach positions us as a key player in tackling climate change and building a more sustainable future.

Water, Sanitation, and Hygiene (WASH)
At Sian Biogas, we are committed to improving public health and environmental sustainability through innovative solutions. Our WASH initiatives target schools, markets, and underserved communities to ensure access to clean water, improved sanitation, and hygienic practices.

Why WASH Matters
Lack of adequate sanitation and safe water access remains a significant challenge in many communities. Poor sanitation not only affects health but also the environment, leading to waterborne diseases, contamination of natural resources, and a decline in community well-being.
Our Solution: Biogas for WASH
Sian Biogas leverages biogas technology to create sustainable and affordable solutions for waste management, which directly contributes to enhancing WASH standards. Our prefabricated and fixed dome biodigesters are designed to manage human waste effectively while producing biogas for energy and clean water from slurry, offering a comprehensive WASH solution.
