How does the Regional Organics Processing Facility Work?

 

Watch the video or read on below to find out more about how we make our compost

 

Organic waste from your lime green organics recycling bins (currently operating in the City of Bunbury and the shires of Capel, Margaret River, Collie, Harvey and Donnybrook-Balingup) is taken to the facility and deposited in large windrows 45m long and 15m wide.

 

The material collected from your verge is high in nitrogen and sugars, so mulched green waste, which is high in carbon, is added to the mix to balance out the carbon to nitrogen ratio. The raw material is the added to windrows which are aerated to minimise odours and speed up the composting process. Our compost champions then pick any unwanted non-organics out to prevent any further contamination. Your organics then starts it journey to a rich certified organic compost.

 

The windrows are monitored for temperature and moisture levels and watered as required. The aeration system is programmed to add air to the windrows at specified time frames.

 

Each windrow is turned to ensure even composting and all parts of the pile are pasteurised. Pasteurisation occurs at temperatures above 55°C. The windrows are turned at least five times and the temperature maintained above 55°C for at least 15 consecutive days to meet pasteurisation requirements. Pasteurisation kills all seeds and pathogens and is one of the most important parts of the composting process.

 

The first screening removes all particles above 50mm and larger contaminants. Leaving a 50mm product ready for maturation.

 

After the piles have been maturated and allowed to cool down further, they are then screened to remove all materials above 50mm.

 

This leaving a high grade 10mm product ready for sale.

 

The screened product is put into a bunker and samples are taken to be tested to the Australian Standard (AS4454-2012) for mulches, compost and soil conditioners. The samples are sent to an independent accredited laboratory for analysis. Testing takes 3-4 weeks and lists the chemical, physical and pathological attributes of the compost and the requirements for Australian Standard AS4454-2012.

 

Compost is then ready for home and commercial use. To view the Laboratory Test Report click on the button below.
