CSR produces rockwool which is used for insulation. It is made from various rocks, such as basalt, limestone and iron slag. The rocks are melted in a cupola (furnace) to form lava that can be spun into fibres that can be formed into insulation products.
CSR, with funding assistance from Victoria’s Sustainability Fund, has developed an inorganic polymer (geopolymer) to bind the waste material so that it can be re-processed into product.
Completed in mid-2011, the plant is expected to reduce:
- the amount of waste going to landfill by approximately 2,100 tonnes per annum
- the amount of raw materials used to make the Rockwool.
About 250 less truck movements to and from the plant are also expected each year.
