Established in November 2008, the Dulverton Organics Compost Facility is the largest composting facility in Tasmania, accepting approximately 40,000 tonnes of organic material per annum from suppliers across the state.

STEP 1

Organic material including garden green waste, supermarket organic waste, woodchips, by-products from the processing of animals, fish, dairy and vegetables, animal straw and manure, and biosolids are delivered to the site

The different types of organic materials are combined by front end loader to ensure an even mix of material types.

The combined mix is placed in long windrows

Every three days, or as often as is needed, a compost windrow turner works along each windrow mixing air and moisture into the compost piles

Every day, temperature probes are used to test the heat levels of the windrows to ensure they maintain the 60C + temperature needed to kill weed seeds and pathogens

After 12-16 weeks of managing the compost, samples are sent for laboratory testing to ensure compliance with the Australian Standard for Composts, Soil Conditioners and Mulches (AS 4454)

The compost is screened to less than 16mm with larger pieces returned to active windrows to decompose further.

The screened, nutrient-rich compost is now ready to use. Compost is weed and pathogen free, granular and easy to spread with a dry weight of approximately 700kg/m3.

Transforming the way we make compost

Dulverton Waste Management has commenced a project to upgrade our composting facility and provide best practice leachate and odour control.

In February 2020, a Development Permit Application was approved by Kentish Council to construct an industrial compost cover and associated mechanical equipment to better manage aeration and moisture of the existing compost windrow operation.  Learn more about the Dulverton Organics Transformation (DOT) project here.
