Alternative Fuels and Raw Materials

As part of our commitment to sustainability and reducing carbon dioxide emissions our Angaston Plant has introduced the use of Alternative Fuels and Raw Materials (AFRM).

Alternative fuels are energy-rich materials such as used tyres, waste wood, used oil, spent solvents and other by-products and wastes. Alternative fuels can be used to replace coal or gas as a source of thermal energy in the cement manufacturing process.

Alternative raw materials are by-products or wastes rich in iron, silica, alumina or calcium carbonate, which can be used to supplement traditional limestone and clay input materials.

The use of AFRMs reduces the impact of potentially harmful items being disposed of as landfill while reducing the burden on non-renewable energy sources. The use of alternative raw materials also provides substantial reductions in greenhouse gas emissions from the cement manufacturing process.


AFRMs have a range of benefits including:

  • Improved business sustainability
  • Reduced site greenhouse gas footprint
  • Reduction in usage of natural resources
  • Beneficial re-use of materials previously landfilled
  • Reduced NOx emissions
  • Contributes to SA government zero-waste strategy
  • No adverse impact on emissions or product quality


Slag, used in cement manufacture, displaces a portion of limestone and clay, which are raw materials used in the manufacture of clinker for cement.

Slag is derived from the smelting industry. Blast furnaces are used to smelt various metals including iron, lead and zinc. During the smelting process, limestone is added to assist separation of the metals from other minerals. During the smelting process, limestone is added to help separate the metals from the other minerals. The remaining impurities are discharged from the furnace as slag.

As slag has already been heated, the carbon dioxide has already been removed. This results in reduced fuel consumption in the cement kiln and a lower carbon footprint.

At current burning rates, we use approximately 5,000 tonnes of slag annually.

Cement Kiln Dust

Cement kiln dust (CKD) is a by-product of the cement manufacturing process. Traditionally CKD has been sent to landfill, which has negative environmental and economic impacts. As part of a broad program of changes aimed at improving our environmental performance and reducing our carbon footprint, we have conducted a number of trials to find a better way to use handle and dispose of CKD.

Used Foundry Sand

Used Foundry Sand (UFS) is a by-product from metal casting operations. The sand is used to make metal casts and as a binding agents. The Environment Protection Authority (EPA) encourages the recycling and reuse of URS waste in order to divert waste from landfills and minimise the use of virgin materials.

Our Angaston Plant uses naturally occurring sand sourced from a local quarry near Tanunda to introduce silica into the raw mix of the process. After a successful trial UFS is now used as an alternative raw material silica source in our cement making process, using approximately 6,000 tonnes annually.

The use of UFS has resulted in significant environmental benefits for both the company and the local community including the removal of waste that is currently being disposed of as landfill and reducing the use of naturally occurring raw material.

The use of UFS at the Angaston Plant has saved the equivalent of more than six Olympic size swimming pools full of sand ending up as landfill each year.

The project has also received support from the South Australian EPA because of its environmental credentials.
