Sanergy offers a variety of bold sanitation and waste management solutions for today's growing cities!
A solution that addresses sanitation and waste management systemic gaps from waste containment, emptying, transport, treatment and reuse of waste generated. Our approach involves building a repertoire of low-cost, high-quality sanitation products and services for residents living in urban non-sewered areas, safely removing all of the waste generated by our customers and transporting it to our central processing plant for treatment and up-cycling into high quality agricultural inputs. To date, we have built a network of over 3,000 Fresh Life Toilets, which serve over 100,000 urban residents with safe sanitation every single day. We also safely remove and up-cycle over 12,000 metric tonnes of waste every year.

Did you know that sugarcane farming supports numerous livelihoods across western Kenya? But sugarcane processing generates large volumes of bagasse waste that heavily contribute to environmental pollution. Today, we are converting bagasse into biochar - a stable, carbon-rich material that improves soil health, reduces emissions, and safely locks carbon for hundreds to thousands of years!
This is regenerative agriculture in action. We are creating sustainable solutions that support farmers, strengthen communities, and protect the environment.

Today we join the world in marking World Water Day. As the Sanergy Collaborative, we continue to play our part by providing safe, inclusive sanitation solutions that protect vital water sources. Through our waterless Fresh Life Toilets, we save billions of water each year and reduce the burden on women and girls. Where water flows, equality grows.
This World Water Day reminds us that are closely connected. In many communities, women and girls carry the greatest burden when water and sanitation are limited, spending hours collecting water, navigating unsafe facilities, all while managing other daily responsibilities.
Safe, clean and accessible water plays a vital role in making life easier and more equitable for women and girls. It improves health, education and the overall quality of life for communities at large. Where water flows, equality grows.

International Women’s Day 2026 offered a moment to pause and reflect on growth, balance, and the power of investing in ourselves as women of the Sanergy Collaborative.
This week, we brought our ladies together for a special reflective session that created space for inspiration and introspection. Through a vision board exercise facilitated by Gladys Wanene and a powerful “Tree of Life” session guided by our key guest, psychologist and mental well-being strategist Tara Ndichu, we visualized the aspirations, goals, and lives we hope to shape; and explored the values, experiences, and relationships that shape who we are.
The conversations of the day were honest and deep. They were a reflection of how women often pour into others that they sometimes forget to nurture themselves. IWD 2026 was a reminder that investing in our own well-being is indeed the first step to investing in others.

As the world gathers in Belém, Brazil to tackle the climate crisis, Sanergy is showing what real climate solutions look like on the ground. By transforming urban waste into valuable resources that is nutrient-rich fertilizer and renewable energy,we’re closing the loop for healthier cities and a cooler planet. Circular economy isn’t just a buzzword for us,it’s daily practice that empowers communities, cuts emissions, and delivers results that global pledges alone can’t. At , we’re calling for climate action that starts with safe sanitation and ends with thriving, resilient cities.

It's not everyday that a Sanergy Collaborative Fellow is recognized as a MacArthur Genius Awardee! Will Tarpeh, who is now a professor at Stanford, worked with us in Kenya in 2012-14. His research focused on extracting minerals like struvite, which is rich in phosphate, from urine. Struvite can be used as an organic fertilizer to help crops grow. This research has been very helpful for us as we work to create value from waste, and therefore make it more cost-effective to provide safe sanitation for residents of urban informal settlements and climate-smart agricultural inputs for farmers across Kenya.
We congratulate Will on the distinction from the MacArthur Foundation, and we are beyond proud of all that he's gone on to done to advance the circular economy and improve people's lives through smart sanitation solutions.
The MacArthur Foundation supports creative people and effective institutions committed to building a more just, verdant, and peaceful world. In addition to selecting the MacArthur Fellows, we work to defend human rights, advance global conservation and security, make cities better places, and unders...

Cities around the world are growing rapidly. Today, the population in urban slums is 1 billion and is expected to increase to more than 3 billion people by 2050. With existing infrastructure already struggling to keep pace, 70% of slum residents live without access to a safe sanitation option. As a result, 1 million people die each year due to sanitation-related diseases, and economies lose $260 billion in impaired productively.
Sanergy has a variety of bold sanitation and waste management solutions for these booming cities! A solution that addresses all systemic gaps from waste containment, emptying, transport, treatment and reuse of waste generated.
Our approach involves building a repertoire of low-cost, high-quality sanitation products and services for residents living in urban non-sewered areas, safely removing all of the waste generated by our customers and transporting it to our central processing plant for treatment and up-cycling into high quality agricultural inputs.
To date, we have built a network of over 3,500 Fresh Life Toilets, which serve over 120,000 urban residents with safe sanitation every single day. We also safely remove and up-cycle over 10,000 metric tonnes of waste every year.
