Composting Facility (North Bannister)

Located at the North Bannister Resource Recovery Facility, our Composting Facility receives and processes household and commercial organic green waste from across Perth and south-west WA.

Each year the facility converts around 23,000 tonnes of garden, food and agricultural waste into high quality compost.

Composting Process

The Facility uses the MAF (Mobile Aerated Floor) composting system. Raw organic material is placed over a series of perforated pipes which an electrically powered fan-box pumps air through. This allows oxygen levels to be controlled every minute of the day – something that cannot be achieved with traditional compost turners.

The composting process takes around 12 weeks.

Compost products

Once processed, our quality compost is used in landscaping and agriculture to reduce water loss and add valuable carbon and nutrients to soils. In many cases, the compost will be used back in the Council areas where the garden waste was originally collected. 

All compost products that leave the site are subject to rigid testing in accordance with Australian Standard AS4454 (composts, soil conditioners and mulches).

Support services

Our services extend to product delivery, assistance in product application and advice on application rates.
