CAPE TOWN - Picture 8.6 billion flies in one room.
It sounds like a horror film, but it is a Cape Town factory's recipe for success.
The protein-based feed for chickens and fish, produced by AgriProtein, is the first of its kind in South Africa.
And, this mash-up of nutrients and insects could lead to a thriving new form of business.
The flies, larvae and maggots are fed prime nutrients gained from leftover food and offcuts.
The insects are then turned into protein feed for the animals humans eat.
"We have a large cage of flies, we get those flies to lay eggs. We grow those eggs on waste that comes from cities. We bring in 250 tonnes a day of waste. We lay 162 million eggs a day," said the CEO of AgriProtein, Jason Drew.
Once big and strong, the insects are dried and defatted and then ground into super feed.
Using this feed for livestock could save farmers money.
Science and Technology Minister Naledi Pandor praised the initiative. "It's a sustainable solution to address food security. In many countries, they're struggling with solutions for feeds for animals, particularly protein."
