City of Monash: Diverting polystyrene from landfill

The Diverting Polystyrene from Landfill project aim was to purchase an expanded polystyrene (EPS) extrusion machine to recycle EPS into briquettes on site, reducing litter and transport costs and to increase the capacity of the Monash Transfer station to receive and divert EPS from landfill, reducing landfill airspace.

The project objectives were to improve collections and source separation of EPS on site and secure an end market for briquettes; increase community awareness of the EPS recycling facility at the transfer station; increase resource recovery by 50% of baseline volume; reduce transport costs by 50% and reduce waste to landfill by 900m3 over 6 months.

The transfer station had participated in a trial EPS recycling project, whereby EPS was stored uncompacted in cages and transported to a recycler. At the conclusion of the trial, the service became a cost to council for transporting EPS. Having established the transfer station as a drop off point and receiving a regular input of EPS, council wanted to continue to provide this service. Research was conducted into the different types of EPS recycling units in use at NSW councils to determine the type of unit fit for Monash. Site selection for the unit commenced including installation of three-phase power and a suitable undercover area for the unit and storing EPS.

The project achieved a reduction of transport costs by 100%, a net increase in customer numbers by 75%, improvements to the collection and source separation of EPS on site, a secure end market for briquettes, increase of resource recovery of EPS by 33% and reduction of waste to landfill by 306m3 over 6 months.

The Diverting Polystyrene from Landfill project achieved a long term, viable and cost effective solution to recycling EPS on site at the Monash Transfer Station. The project required minor resourcing to deliver considerable increases in diversion of EPS from landfill. The project has created a lasting EPS recycling solution with the capacity to increase the amount of EPS received and recycled into the future.
