OUR COMPOST MAKING PROCESS

When vegetation and green waste are mulched into finer organic material, the resulting product provides the raw carbon source for our composts. Organics are repositioned to form compost pile windrows up to 100 metres in length at our industrial composting facilities and are composed of composting materials like food scraps, garden waste and other organic matter. A range of different nitrogen sources can be added to achieve the desired nitrogen-to-carbon ratio.

Additional liquids are added to the compost rows to ensure moisture levels remain at 40-50%, encouraging optimal breakdown of organic waste during the composting process. The windrows are turned on average about 40 times during their life cycle, effectively managing greenhouse gas emissions. The frequency of the turning is determined by regular temperature and moisture checks. Batches are aged for a minimum of 16 weeks and transformed into finished compost materials.

Every windrow is sampled and stringently tested to ensure compliance and the Australian Standard AS4454 is achieved. These quality checks and balances ensure the end product is of the highest quality and fit for purpose.

Carbon Plus Compost has a purpose-built Komptech X60 windrow turner to ensure optimal mixing and aeration of food waste and other organic materials. The finished product is screened to 16mm minus prior to sale.

The Carbon Plus Compost process has been inspected and received approval as a Freshcare-recognised supplier, affirming our commitment to sustainable practices and superior product quality.
