The family-run Gow Street Recycling Centre has been given the greenlight from the Minister for Planning to construct and operate a liquid waste recycling facility with the capacity to process up to 250,000 tonnes per annum of drilling mud and concrete washout water at 81 – 87 Gow Street in Padstow.

The liquid waste facility will be co-located with the existing waste facility, which operates under a variety of development consents granted by the Canterbury-Bankstown Council. This approval allows the business to increase the recycling of a waste that is costly to dispose of and that few facilities are able to recycle in NSW.

The Minister’s sign off permits the demolition of an existing office building, awning, demountable lunchroom and partial demolition of a warehouse. It also includes construction of a new office, waste bunkers and installation of equipment in the extended warehouse.

The facility will store up to 1460 tonnes of liquid and related waste at one time with 33 kilolitre diesel tanks and liquid waste treatment plants and machinery to be installed within the warehouse.

Gow Street Recycling is a family-owned and operated business, which has operated at the site since 2016. It holds a licence to transfer and crush up to 80,000 tonnes per year of construction and demolition waste into reusable products for use in building and construction. This operation will not be impacted by the liquid waste facility.

Waste generated from construction and demolition activities historically end up in landfill. Increasingly, businesses are seeing waste as a potential resource, which has resulted in a growth of recycling facilities to repurpose waste in NSW.

The family-run business will capitalise on the growing need for facilities to treat liquid waste, as disposal is costly and water is increasingly becoming a more precious resource, yet few facilities are presently available to recycle such waste.

With Southwest Sydney seeing an influx of new infrastructure projects, as well as a high demand for residential development, the region is generating significant quantities of liquid waste associated with this activity.

The state-wide Waste Avoidance and Sustainable Material Strategy 2041 sets targets for waste reduction and landfill diversion to transition to a circular economy, including an 80% average recovery rate from all waste streams by 2030.
