The strategy revolves around self-operating, modular farms where black soldier fly larvae—essentially maggots—are employed to decompose food waste, transforming it into both animal feed and fertilizer.

Although maggots can make many people uneasy, Yarger acknowledged their crucial role.
According to the Department of Climate Change, Energy, the Environment and Water, food waste contributes approximately 3 percent to Australia’s yearly emissions.
Australia is facing ‘a landfill crisis’
“Between one quarter and one third of all the waste generated is food waste. We need to keep this out of landfills.”
The clever system allows her business, Goterra, to address the food-waste problem while also turning a profit.

Larvae are placed into crates at five days old and, over 12 days, produce nutrient-rich fertiliser for farms. Before the larvae mature into flies, they are converted into poultry feed.
“The feed is also full of amino acids which are essential for chickens to produce eggs.”
The ‘biggest’ problem is contamination
“This is what businesses must do when mandates come in next year because it is so important to keep the stream of organic material clean for products like compost.”

Yarger is now preparing for major national expansion. From one small bucket in her garage in 2016, her business has grown to seven sites across four states.
