Kwinana BioWise ARRT Facility

By providing an economic solution for biosolids disposal, SITA is diverting waste from landfill and delivering the horticultural, landscaping and nursery sector with a high quality product.

The SITA Organics BioWise ARRT facility has the capacity to process up to 50,000 tonnes per year of organic material, including biosolids, shredded garden organics, grease trap waste and food wastes.  This material is converted into high quality composts and soil conditioners.

The composted organic products are tailored to meet market demands, and the process is designed to consistently deliver this outcome. Incoming feedstocks are carefully blended in proportions that ensure the resulting compost meets end use requirements, with parameters including correct moisture content and ratios of nitrogen and phosphorous.

The mixed organics are composted in an aerated, static pile  system, which enables the temperature and moisture levels in the compost to be monitored and controlled, optimising the breakdown of the organics and destroying pathogens. The compost is then matured and tested.

SITA was the first organisation within the Perth compost market to introduce transparent data collection and testing to AS4454, becoming the first company in Australia to achieve AS 4454 - Composts, Mulches and Soil Conditioners accreditation for its products.

BioWise products help address environmental issues such as sandy soils, salinity, water conservation, nutrient leakage into water and rivers, use of chemical fertilisers and greenhouse gas reduction.

The benefits of BioWise compost for horticultural, landscaping and nursery applications include:

  • Water saving through moisture retention
  • Increased soil microbiological activity 
  • Helps suppress plant diseases
  • Improves soil texture – builds up organic matter
  • Pathogen free
