Up: vermi-compost; biochar; Struvite. Down: briquettes; fireballs; pellets
The project intends to develop and produce products from human waste. A broad range of products have been developed and are being tested for their safety and quality.
For bio-fertilisers the following products have been developed as options for market-uptake in Nakuru:
- compost made from human waste and market waste using an anaerobic process;
- vermi-compost from human waste and market waste for which worms were used to assist in decomposition of the materials;
- biochar made from carbonised and crushed human waste
- dried and crushed faecal matter
- Struvite, out of pure urine
For biomass-fuels the following products have been developed as options:
- carbonised sausage type briquettes (made with an extruder)
- carbonised fire-ball type briquettes (made with an agglomerator)
- non-carbonised fuel-pellets (made with a pelletiser)
- industrial size briquettes
These fuels are made out of mixtures of market waste, sawdust and human waste. As a binder starch, molasses and faecal matter have been explored.
The photos give an impression of the products developed.
