Recycling provides a double benefit; it reduces the volume of waste being sent to landfills and simultaneously limits the volume of new raw material inputs required in manufacturing processes.  This is why the new recycling technology developed at UNSW is so important. It relates to the use of waste materials in the production of steels.

This technology is largely directed to repurposing rubber from used tyres instead of coking coal.  This not only removes impurities but also puts iron back into the steel.  This can result in the consumption of 12-16 percent less coking coal and a drop in electricity requirements.

The technology is also economically attractive. It can reportedly result in cost savings exceeding 10 percent.  In fact, it is already being used commercially by Arrium who have a global license for the technology.
