ReCirculator

Improving productivity by reducing costs and enhancing the value of waste outputs.

The Northern Rivers Regional Circular Economy Accelerator

The ReCirculator program is a $2 million Federal Government-funded initiative forming part of the Strategic University Reform Fund (SURF).

Designed to act as an independent broker, The ReCirculator will support information exchange, research and technology implementation to accelerate the adoption of circular economy principles in the Northern Rivers Region of NSW.

This will involve conducting, publishing and facilitating world-leading research to enable adoption of circular economy principles in the NSW Northern Rivers region.

“The difficulty for industry lies in not having the capacity to really test processes and techniques. Recirculator solves that by testing and evaluating new waste management processes that deliver economic, social, and environmental gain.”

Led by Southern Cross University, ReCirculator is a research hub and technology brokerage that connects NSW Northern Rivers businesses in a circular economy ecosystem of cutting-edge technology. It acts as an economic growth driver by:

  • saving costs
  • improving productivity
  • regenerating resources
  • creating resilient jobs.

Aiming to help local businesses to enhance their efficiency by adopting circular economy principles that:

  • identify the composition of their waste streams and any materials and energy that could be recovered from it
  • combine wastes from compatible partners to create commercially marketable outputs and/or products, and
  • identify, trial and optimise technological solutions to waste reuse and recovery, and assist with their uptake on a commercial scale.

To do this, The ReCirculator will:

  • provide access to the technical facilities and expertise of Southern Cross University and its research partners for waste characterisation, testing of resource recovery potential, plus piloting and optimising suitable technology before commercial adoption
  • provide techno-economic modelling expertise to identify and apply commercially viable solutions
  • act as a trusted technology broker for industry, using links between Southern Cross University and both national and international technology and research providers, and
  • build a network between the university, industry, regulators and government to foster information sharing and technology adoption to create meaningful change

They represent a targeted approach to a common goal – a better, safer, more sustainable world. 

Benefits of a circular economy

Reduce waste and pollution

Keep products and materials in use

Create employment through products developed from waste materials

Demonstration projects

The ReCirculator is running four demonstration projects targeting significant waste streams in key Northern Rivers industries. The efficiencies established in these pilot projects are scalable, meaning they can be adapted for commercial uptake up by similar businesses in the future.

  • Project 1: Thermal treatment of waste
  • Project 2: Plastic waste –recycling into the Circular Economy
  • Project 3: Capturing nutrients from industrial wastewater
  • Project 4: Carbon accounting
  • Project 5: Waste identification and sorting
  • Project 6: 3D printed housing – Studio Kite

Industries supported by these pilot projects include food production and manufacturing.

Equipment

Testing the quality of biogas generated through an anaerobic digester at Richmond Dairies in Casino. This gas can be used to heat and power the factory.

Recirculator equiptment 1

Collecting wastewater from the anaerobic digester at Richmond Dairies to test ways of extracting nutrients which can then be used as a fertiliser.

Recirculator equiptment 2

Casino Hide Tanners - breaks down organic pollutants in effluent, meaning it can be safely used for irrigation, rather than having to be disposed of at specialised landfills.

Recirculator equiptment 3

Using the Static Pile Inoculated Composting process at scale, this project demonstrates how composted material can improve pasture and build soil health.

The ReCirculator and Plastics Pirate bring the Circular Economy to Stanthorpe

SQNNSW Innovation Hub and Southern Downs Regional Council invited Southern Cross University’s ReCirculator team and their industry partner, Plastics Pirate, to conduct a Circular Economy demonstration and information session at Stanthorpe on 6 December.

Attendees from the Granite Belt Growers Association, Southern Downs Regional Council, local industry – and from as far afield as Glen Innes and Kingaroy – saw how the Plastics Pirate pyrolysis technology can convert waste plastic into fuel or feedstock for new plastics.

The overwhelming interest shown at this event will support further demonstrations within the region and, ultimately, the commercial rollout of the technology.
