Worms at Work is a City of Melbourne pilot that turns ordinary street furniture into living composting benches.

Developed through the Fishermans Bend Digital Innovation Challenge, it brings together design, technology and community to make composting part of everyday city life.

Three benches across Fishermans Bend and Yarra’s Edge are now helping residents and businesses turn food waste into rich compost.

Watch the video below to hear from the collaborators and community champions who made it possible.

We are installing three garden beds at different locations in Fishermans Bend - it's a seat, a garden bed and compost.

We got shortlisted in the Fisherman's Band Digital Innovation Challenge and I invited Michael on board and we did the pitch together.

We won that competition, we won a $90,000 prize. I thought this is a chance to make composting part of everyday life in Australian cities.

In March we did a community workshop at Yarra’s Edge.

We've got these compost champions and they're organising the community. We're giving ownership of this project to the people who need to use it.

The purpose of tonight was to discuss how we can get the community involved in recycling, kitchen waste and green waste rather than consigning it to landfill.

We get a lot of feedback around how they want the worm farm to look like, feel like, and then that helps us to, develop to the criteria what the bench design will look like.

So today we have the first worm bench being installed at ST. ALi Roasters. We will have our second one in Yarra’s Edge, and then the third one will be in front of Susuro Wine Bar - it's a different design. It's a slimmer profile.

So they're like garden furniture, but they're also compost that turns food waste into soil, into nutrients, and reduces food waste at cafes, households and apartments. When people put food waste in, they get rich compost, which is the best fertilizer. Some cafes that have been doing this with, prototypes that I’ve developed have halved their food waste bill. So you can save money by composting food waste.

We have different sets of sensors for the worm health. We have temperature, moisture sensors, worms breathe through their skins, they need 70% 80% of moisture levels. We want to make sure they get comfortable in there, and then we have pH sensors, so help us to monitor if the compost gets too acidic.

What we want to do here is end food waste by showing how easy it is to compost in the street. The fact that Melbourne City Council is going out and thinking about doing composting in the public with this project, just gives me so much respect for the council. I imagine Melbourne being greener, cooler, cheaper. This is not just about compost, this is about how we live in our cities. I want people to reconnect in a village way.

What I really, really want for this project is change people's feeling about composting, making it very easy to use, very beautiful. That's part of nature.

Pilot collaborators

The Worms at Work pilot is the result of a collaboration between the City of Melbourne and two creative innovators: Zoe Wang (Upsoil Collective) and Michael Mobbs (The Off Grid Guy).

Zoe and Michael were selected as winners of the Fishermans Bend Digital Innovation Challenge for their composting bench concepts that combine smart design with circular economy principles. Their unique approaches bring together community use, sustainable materials, and environmental education in the form of street furniture.
