Circular Plastics system raises the bar
The Circular Plastics wastewater treatment plant provides one of the most advanced levels of treatment.
AEROFLOAT HAS SET A NEW BENCHMARK WITH A WASTEWATER SYSTEM FOR ONE OF AUSTRALIA’S BIGGEST PLASTIC RECYCLING FACILITIES.
A
erofloat’s most advanced wastewater treatment system so far for the plastics industry is in the final stages of commissioning. The wastewater treatment specialists designed and installed a system for a Circular Plastics Australia PET recycling facility in Albury-Wodonga, New South Wales. The plant, a joint venture between Cleanaway Waste Management, Pact Group Holdings Group, Asahi Beverages and Coca Cola Europacific Partners is expected to be Australia’s biggest end-to-end recycled polyethylene terephthalate (PET) plant and is expected to recycle up to one billion 600ml PET plastic bottles a year. It is the third project Aerofloat and Pact Group have worked on together.

Aerofloat has created sustainable wastewater treatment designs for major plastics recycling businesses across Australia and has been awarded for its innovative approach to tackling plastics recycling wastewater issues. Michael Anderson, Aerofloat General Manager of Engineering, says the Circular Plastics water treatment system pulls together all the elements of previous systems Aerofloat has designed for the plastics industry. “Stages of the treatment process have all been done at other sites but in the plastics industry, this is the most advanced plant that we’ve done to this level of treatment,” Michael says. “We’re really happy with what we’ve achieved.”
The Aerofloat design had to ensure a sustainable, long-term solution for Circular Plastics and allow for the expansion of the recycling facility in the future. Clean wastewater from the system is either re-used as wash water within the plastics recycling facility or discharged to sewer, helping to reduce the company’s footprint with savings on water usage. Aerofloat installed its patented circular dissolved air flotation unit, the AeroCircDAF, to treat higher flow volumes of wash water. It also included its fully automated, intelligent PLC control system to accommodate the integration of additional Aerofloat technology as the business expands. Michael says Aerofloat worked closely with the local council to ensure strict
