Water runoff from a rain event collects and transports soil, pet waste, pesticides, fertilizer, oil and grease, leaves, litter, and other potential pollutants that can ultimately wind up in our stormwater drain.

CORE has completed over twenty years of research in the use of recycled organics as well as other recycled materials for treating water runoff using bio-filtration. The end result is Advanced Bio-Filtration Technology, regarded as world’s best practice. The technology is now being used in urban, industrial, agriculture or mining applications in five major countries around the world.

You can contact us on info@core.asn.au for a copy of the “Performance based Standard for Organic Bio-filters”.

Read more about how Advanced Bio-Filtration Technology is being implemented in case studies below.

20 Years of protecting the Sydney Harbour

CORE  have provided organic bio-filters that now “ring” Sydney Harbour and its tributaries from Manly to Annandale (installed in 1998) through Redfern and Sydney and around to Rose Bay. Bio-Filters are used in a range of stormwater treatment systems such as rain gardens, bio-swales and detention basins that are installed in streetscapes, parks and reserves.

“Greening The Gutter” Program

CORE has been researching water treatment using recycled materials for more than twenty years with a strong focus on storm water from urban, industrial and agricultural sources. We are astonished at the atrocious water quality results we have witnessed over time and what little is being done about it. While a lot of effort has been put into gross pollutants you can see with the naked eye, dissolved pollutants such as nutrients, metals, toxic compounds and micro-plastics receive far less attention.

CORE is proud to launch the “Greening the Gutter” program that addressed the above issues. We aim to revolutionise the way we drain water from our communities.

Sponge Parks – How cities are using nature to overcome extreme weather

As the world’s climate changes, scientists expect an increase in the frequency and intensity of extreme weather events, such as the heavy rainfall that can cause flooding or drought that can cause water scarcity. We need to draw inspiration from the natural world and look for nature-based solutions to protect and sustainably manage ecosystems to adapt to these expected extreme weather events.
