43,473 TONS OF WASTE SAFELY REMOVED
FROM THE COMMUNITY EVERY YEAR
The waste is removed from the community by handcarts and trucks. The handcarts ensure we can install toilets
deep in urban slums where there are only narrow, unpaved roads as access points. The waste is then
taken out of the community by a professional logistics team using trucks. As the urban populations throughout
East Africa grow, so does the solid waste management burden – a situation worsened by a lack of regulations’
enforcement. Nairobi produces about 1 million tons of solid waste per year and only 50% is collected. Most of it is illegally
dumped, posing a huge risk to the environment. We offtake organic waste through City Fresh – a green waste
management company. To learn more, please visit their website or reach out to [email protected]
SELLING HIGH QUALITY FARM INPUTS
TO OVER 1,000 KENYAN FARMERS
We convert the waste at a centralized facility into valuable end-products such as
organic fertilizer and insect-based animal feed. To produce the insect-based animal feed, we have a colony of Black
Soldier Flies, whose larvae consume organic waste. The pathogen-free larvae make sustainably
produced, nutrient-rich protein input for animal feed.
To produce the fertilizer, frass residue from Black Soldier Fly production processes is mixed with carbon sources
from plant waste. We use windrow management technology to systematically measure temperature, aeration,
and moisture content to ensure a high-quality compost.
Once ready, we test our end-products by third parties to ensure compliance with international standards.
