Germany-based Remondis is one of the world’s leading recycling companies, and recently opened an organic waste treatment facility in Lake Macquarie, Australia.

Remondis has locations in 30 countries. One of them is Australia, and in July 2018 Remondis, the city of Lake Macquarie and Komptech distributor ELB Equipment Pacific celebrated the opening of a new A$ 10 million organic waste processing facility in Awaba.
The state-of-the-art facility is one of the most advanced of its kind in Australia. It is capable of recycling not only green waste organics, but also food waste, to produce a safe, high quality compost that meets strict Australian standards.

Food waste presents several potential risks and health concerns if not handled correctly. It must be thoroughly pasteurised in a controlled environment before it can be composted. To this end, Remondis installed five fully automated tunnels at the site, which ensure the safety and quality of the output while also keeping noxious odours to a minimum. Organic waste comprises as much as 60% of the waste stream. While green waste organics are turned into mulch and compost, food waste, making up approximately 40% of the organics volume, presents more of a challenge – and that challenge has now been met. Thanks to the technology employed at the Awaba facility, the Lake Macquarie City Council can reduce its landfill rate by as much as 30%. This not only helps preserve resources, but also saves taxpayers millions of dollars in tipping fees.

ELB Equipment was selected to supply the site with a Komptech Multistar L3 star screen. The key factors influencing the decision were ELB Equipment’s reputation for unmatched aftersales service and support, and Komptech’s reputation for star screens that offer superior performance and throughput in applications with wet, sticky organics. With an annual workload of 44,000 tonnes, it was important that the plant have high uptime and consistent throughput. The Multistar completes the final phase of processing the organic waste into compost by separating the material into three size fractions. The oversize fraction is either returned to the process for further breakdown or used for landfill daily cover. The midsize fraction is used for gardens and flowerbeds, and sold as mulch. The fine fraction is used on municipal sports fields and parks, and sold to the public as a high quality, nutrient-rich compost to improve soil health and help with drought tolerance.
