Food organics high-rise pilot

City of Melbourne is piloting the use of on-site organics processing technology in high-rise residential buildings to reduce the amount of organic material going to landfill.

Man chopping vegetables and putting scraps into a benchtop compost bin

Selected residential apartment buildings (six storeys or higher) are participating in a twelve-month pilot program which explores the effectiveness of on-site organics processing technology.

Residents deposit their food scraps directly into an on-site organics processor, which dehydrates the organics and reduces its volume by up to 80 per cent. The resulting materials are then turned into a high nutrient soil conditioner. 

The pilot will conclude in late 2026 when it will be evaluated. The results will be used to plan and design food organics collection system for existing and future buildings. 

If your building is participating in this pilot, please see below for building-specific information and updates.

Text says 'ecoguardians: SoilFood System User Instructions. Soilfood'

The Eco Guardians SoilFood system is very easy and simple to use.

Bring your caddy with your food waste. Use your fob or personalised passcode to unlock the system. Then slide open the door.

Place your compostable bag in the unit and close the door. It's as simple as that.

Most organics can be used in Eco Guardians SoilFood system, but if you're not sure please refer to the checklist that you received.

Text on screen reads 'ecoguardians: For more information please visit www.ecoguardians.com.au'

Frequently asked questions

If you did not attend an information session or you've just moved in, please contact your building manager for an introduction to the service.

Your kitchen caddy is used to collect and transfer food scraps to the dehydrator. Place the caddy in a convenient place, such as your kitchen bench, and start collecting food scraps.

Compostable liners are used to line your kitchen caddy. Once your caddy is full, take it to the organics processor, lift the bin liner out and place it into the organics processor. Do not tie a knot in the bag.

It is important to only use council-approved compostable liners, as only these will break down during the dehydration process. Other plastic, degradable and biodegradable bags must not be used with your kitchen caddy. They can contain harmful plastic and heavy metals that will contaminate the organic material and damage the processor.
 

You will receive enough caddy liners to last you one year. If you run out, please speak to your building manager to get more.  

You can also purchase your own compostable bin liners through COMPOST-A-PAK External link.

At times the organic processor won’t be available due to cleaning and maintenance. Please do not leave your caddy or food scraps next to the organics processor. Check the operating schedule beside the organics processor and return during operating hours. 

Speak to your building manager about a replacement caddy. 

Please do not take the kitchen caddy with you when you move out. Wash and dry the caddy and leave it, along with any unused compostable liners, in the apartment for the next tenant.

Return the organics processor access card to building management or leave it along with the kitchen caddy in the apartment.

Please speak to building management about a replacement card or fob.
