The Byron Bay Concrete Plant has switched to 100 per cent renewable energy as part Holcim Australia’s commitment to reducing carbon emissions.
Last year, the concrete plant managed to eliminate all Scope 2 CO₂ emissions via electricity use on-site. The achievement was made possible through on-site solar generation and 100 per cent renewable energy supplied by Shell Energy.

According to Holcim Australia. The plan receives 20 per cent of its electricity needs from its solar panels, with the remainder sourced from certified renewable energy.
“On-site solar has been a great first step in achieving our Zero Scope 2 target, but it will never be able to cover 100 per cent of our requirements—our operations run at times when the sun doesn’t shine,” Holcim procurement business partner Chris Marathakis said.
“That’s why we supplement our energy needs by purchasing renewable electricity from large-scale projects by retailers like Shell Energy.”
The milestone in Byron Bay is part of Holcim’s Global Health, Safety, and Environmental Improvement Plan which includes objectives like zero emissions from electricity use.
“The Byron Bay Concrete Plant follows in the footsteps of our Jacobs Well plant in Queensland, which has been operating on 100 per cent renewable energy since 2023 using a similar mix of on-site solar and grid-sourced green energy,” Holcim Australia said in its release.
“We remain committed to advancing sustainability within our operations and beyond – such as our waste reduction that successfully diverted 4.6 tonnes of waste from landfill, primarily through timber and cardboard recycling at Brisbane (Eagle Farm) concrete plant.”
