The Alternative Raw Materials (ARM) Project is a key decarbonisation initiative being undertaken by Boral at its Berrima Cement Works. The project is expected to reduce carbon dioxide (CO₂) emissions from cement manufacturing by up to 100,000 tonnes per year, making it one of the most significant emissions-reduction projects in Australia's cement industry.

Located in the Southern Highlands of New South Wales, Berrima Cement Works is a strategically important manufacturing facility for both Boral and Australia. The site supplies up to 40 per cent of the cement used across New South Wales and the Australian Capital Territory, supporting major infrastructure, commercial, and residential construction projects.

Supported by $24.5 million in funding from the Australian Government, the project plays a critical role in Boral's broader decarbonisation pathway. It targets process emissions, the largest and most challenging source of emissions to abate in cement manufacturing.

The project involves the installation of a specialised grinding circuit and associated infrastructure at Berrima Cement Works. Once operational, the new grinding circuit will enable Boral to significantly increase the use of alternative raw materials (ARMs) in the kiln feed, increasing the substitution rate from approximately 9 per cent to up to 23 per cent. This will reduce reliance on limestone, the primary raw material traditionally used in clinker production.

Reducing limestone consumption is a vital step in lowering cement manufacturing emissions. During clinker production, limestone releases CO₂ through a chemical process known as calcination. This process is responsible for approximately 55 per cent of the cement and concrete sector's emissions in Australia and is widely recognised as the industry's most difficult-to-abate emissions source.

By increasing the use of alternative raw materials, the ARM Project will substantially reduce these process emissions while maintaining the quality and performance of Boral's cement products.

Opportunities for Local Suppliers and Contractors

Boral is committed to engaging local businesses throughout the delivery of the project and is seeking expressions of interest from suppliers and service providers across various project phases.

In particular, opportunities are expected for civil, mechanical, and electrical contractors operating in the Southern Highlands region of New South Wales. Businesses interested in participating in the project are encouraged to contact Boral to discuss potential opportunities and capability requirements.
