If plants are the lifeblood of our industry, soil must surely be the heart. And healthy soil is vital. It is fortunate then that MLSA boasts two organics recycling companies, not only as members but proud sponsors too.

South Australia is decades ahead of other states when it comes to how we deal with our recyclables and green waste. Peats Soils has been a South Australian institution for 45 years and has often been at the forefront of this movement, campaigning tirelessly and influencing policy where required.  With a firm grounding (no pun intended) in scientific evidence, Peats works alongside company scientists and industry professionals, continually working with the business to improve processes and products that are certified and tested to meet Australian standards.]

Peats products are used in Viticulture, Horticulture and Broadacre sectors and by civil, local government, landscape and turf professionals. Growers and landscape yards are supplied by four strategically positioned sites across the state – Willunga, Brinkley, Dublin and the first regional site at Whyalla.

So, who better than to spearhead the organics industry in Darwin?

Peats Soils recently opened their fifth organics processing and manufacturing site, co-located at Shoal Bay Waste Management Facility in the Northern Territory. It started organics processing operations on 1st April 2020 in conjunction with processing partners Katherine Tree Maintenance (KTM) and site operators Veolia. Together, they produced a whopping 10,000 cubic metres of mulch products in the first three months of operation. Plans are in place for the processing facility to be fully operational by mid-2021. Drawing on their years of composting experience and expertise, streamlining the processing of the current organic materials and growing the capacity of the Darwin site will be paramount.

This new site’s operations will provide businesses and City of Darwin residents with a solution for their green waste and will significantly divert organic materials from landfill. The breakdown of organic materials in landfill generates the potent greenhouse gas methane and produces potentially polluting leachate. From a climate perspective, diverting green waste from landfill has the largest impact of any solid waste component.

Apart from the environmental reasons to divert green organics from landfill, the processing of these materials produces nutrient-rich soil improving products for growers, farmers, landscapers and gardeners to use.

City of Darwin CEO, Scott Waters said he was delighted to see Shoal Bay diverting waste from landfill and turning it into a valuable commodity: “The creation of mulch from green waste represents a circular economy; we are extending the lifecycle of this resource by recycling and repurposing it to create a saleable material.”

Peter Wadewitz, Managing Director of Peats Soil repeated the sentiment: “Composting is a circular economy in action. There is nothing more rewarding than being part of an industry that sees plant and organic materials as a resource rather than waste and transforming this resource into composted products that feed the soil. These products are used to green-up our suburbs, improving our plant-life balance, and improve soils that grow more plants and nutrient-rich food. And so the cycle continues.”

We wish Peats Group every success with this new endeavour.

Peats Soil & Garden Supplies operates four sites in South Australia – Willunga, Brinkley, Dublin and Whyalla. Along with advanced composting facilities, Peats have developed a biodiesel manufacturing plant and renewable energy technologies.
