Chickens double their output and crops blossom from the fertilizer.
And it’s all done without chemicals.
Nestled beneath her squat-toilets are small blue barrels that, once full, are sealed and taken to an organics recycling factory in Machakos County, a bumpy 40-minute drive outside the city.
Beds of writhing black soldier fly larvae feast on a mix of excrement and food waste from hotels and agri-businesses.
That produces two products for farmers: fertilizer and animal feed.
In 10 days the larvae munch their way through 70% of the waste, leaving behind a manure laden with nitrogen and calcium, which becomes organic fertilizer.
Once the recycling plant is expanded later this year, Auerbach said it will provide 400 tonnes of fertilizer. Larvae production will ratchet up from 7 tonnes to 300 tonnes per month.
Right now we are receiving equity debt, and grant investment to scale up operations,” Auerbach said. “We’re on track for profitability by the end of 2020.”
The plump white larvae are boiled in hot water to kill off pathogens, Michael Lwoyelo, managing director of Sanergy, said.
The larvae are then sold to animal feed millers, who grind them into powder mixed with other ingredients to create a balanced diet for poultry, pigs and fish.
