Thermophilic composting is a process that involves creating a controlled environment to break down organic materials using heat-loving microorganisms (thermophiles).
The Wormtech Carrathool Composting Factility is an EPA licenced facility that converts organic waste diverted from landfill into rich compost. The thermophilic composting process used at the site involves mixing and arranging layers of organic waste materials, such as kitchen scraps, yard waste, and commercial organic waste from food production, to create a balanced carbon-to-nitrogen ratio. The key to achieving a nutrient-rich compost is the addition of water, which is added in the first 2 to 3 turns of the compost pile. This creates an environment of at least 40% moisture that acts as a catalyst for thermophile activity. The compost pile is turned and aerated regularly to prevent internal combustion from overheating.

Tonnes of Organic Waste Diverted from Landfill by Worm Tech.
When organic material breaks down, beneficial products are formed that can increase soil quality and productivity and yield many climate change benefits (PDF 947KB).
In nature, organic material gradually decomposes and returns nutrients back to the soil. Licensed composting processors use various systems to speed up this natural process.
Composts today are made from materials such as food and garden organics from household green bins, green waste from commercial landscaping activities, or commercial food wastes.
Manufacturing quality compost that meets customer requirements is vital to operate a successful organics recycling facility.
Voluntary industry standards, such as those published by Standards Australia, provide guidance to manufacturers.
Australian Standards relevant to recycled organics or compost include
Australian Standard AS 4454 (2012): Composts, soil conditioners and mulches
Australian Standard AS 3743 (2003): Potting mixes
Australian Standard AS 4419 (2016): Soils for landscaping and garden use
Australian Standard AS 4422 (2016): Playground surfacing
