About our Compost

Established in November 2008, the Dulverton Organics Compost Facility is the largest composting facility in Tasmania, accepting approximately 20,000 tonnes of organic material per annum from suppliers across the state. This facility was opened to offer clients a cleaner and more sustainable by-product management option and to provide the community with an affordable high quality organic compost.

Dulverton Organics Compost is made to a strict scientifically calculated formula, using only high quality organic material sourced from suppliers across Tasmania. To ensure suitability, nutrient and element analysis’ are taken of the organic inputs prior to introducing them to the process. Inputs include garden green waste, lawn clippings, tree loppings, forestry and sawn log residues, fish waste, biosolids, milk & cheese sludge and brewers yeast. This diverse mix of ingredients makes for a nutrient rich final product, which resembles rich dark soil with a dry weight of approximately 700kg/m³.

The organic material is mixed in specific ratios to ensure optimum nutrient and composting outcomes are achieved and then it is formed into windrows. Over the 16 week composting process the windrows are monitored regularly for moisture, temperature and oxygen levels. The 3 parameters are maintained within our pre-determined tight tolerances in accordance with our Environmental Management System and the Australian Standard for Composts, Soil Conditioners and Mulches (AS 4454).

Once a windrow has finished composting and has been tested to ensure compliance with AS 4454, it is screened to less than 16mm to produce Dulverton Organics Compost – a final product that is weed and pathogen free, nutrient rich, granular and easy to spread.

Dulverton Organics Compost has proven to be very popular among farmers looking for an alternative to synthetic fertilizers. Some other common uses are in agriculture, orchards and vegetable growing. Bulk purchasing is available; please visit the ‘Purchase’ section for more information.
