Biobuu

Biobuu is a Tanzanian company that collects organic waste and turns it into high-value products: compost, alternative fuels and low-carbon materials. The company points to the large volumes of organic waste that go unmanaged across Africa, polluting cities and adding to emissions.

Its website explains the problem, its products, team and partners. Biobuu's model links waste collection with processing and sales to farms and industry, aiming to turn a pollution problem into inputs for a lower-carbon economy. The company targets cities, farms and industrial buyers.
