Transforming Food Waste into Purpose

Goterra’s Circular Innovation at International Towers

Last week, a group of our tenant partners toured the Goterra facility at Wetherill Park, hosted by Justin Frank, Head of Strategy and Communications at Goterra. The visit offered a close-up look at the technology powering the on-site Goterra Waste Hub at International Towers — and a deeper appreciation for the circular system transforming food waste beneath our feet.

Since launching in 2020 at Intermational Towers, the Goterra Waste Hub has been turning organic waste into valuable resources — using robotics and Black Soldier Fly larvae to process over one tonne of food waste daily, right here on-site. This closed-loop solution produces nutrient-rich fertiliser and high-protein feed, supporting Australian agriculture and reducing landfill reliance.

• Food waste is collected from across the precinct in green bins
• It’s weighed, blended, and fed to larvae inside the Goterra unit
• In 10–12 days, the larvae consume the food and grow into a sustainable protein source
• The remaining material is processed into fertiliser to return nutrients to the soil
• The cycle continues — turning waste into resource, again and again

Impact Snapshot: 2024 Year-to-Date

Thanks to the support of tenant partners and building teams, the Goterra Hub has achieved:

• 251.82 tonnes of food waste diverted
• 10.07 tonnes of feed for farmers produced
• 50.36 tonnes of insects fed for a day
• 478.46 tonnes of CO₂ emissions prevented

The 24% material output from food waste input is largely the result of natural water evaporation an expected part of the organic breakdown process.

We’re incredibly grateful to our tenant community for their ongoing support of this initiative. Together with Goterra, we’re not only reducing waste — we’re building a precinct where innovation and sustainability go hand-in-hand.
