I'm part of a new social enterprise called Circular Food. After learning about the huge global issue that is food waste, we wanted to do something about it!

We now operate the largest urban worm farm in Australia. We take in food waste (at the moment we take all our waste from a local restaurant making their business zero waste!) and we process that waste through commercial scale worm farms. 

We add some other ingredients, such as garden lime and compost to ensure the environment is perfect for the worms. The end product is a liquid and solid fertiliser product, full of microbial life.

Nature always intended for organic waste to return to the earth. The humble earthworm is one of the most important creatures on the planet, as it turns this organic waste into plant available nutrients. 

What is a provocation or insight that might inspire others during this challenge?

Why not use food waste to produce more food? Its the cycle of life that was intended by nature. We want to encourage everyone to adopt small scale worm farming in order to deal with your own household waste, as well as inspire you to have a go at growing your own food. We also support farmers to change over to organic practices and manage their own farm waste in a beneficial way.

Tell us about your work experience:

I studied Strategic Comms at La Trobe in Melbourne. My previous job was for an electronics recycling company. I now work at Circular Food full time. Sustainability is my passion!
