Working towards achieving its net zero goals, Laing O’Rourke is conducting trials of 100 per cent hydrotreated vegetable oil (HVO100) on Australian projects.

HVO100, derived from vegetable oils such as rapeseed or waste-based feedstock like used cooking oil, offers a substantial reduction in greenhouse gas emissions compared to diesel derived from fossil fuels. Recognising the construction industry’s significant contribution to global emissions, phasing out diesel is crucial for meeting net zero targets.

Hollie Hynes, general manager of sustainability and environment at Laing O’Rourke, said that the adoption of renewable liquid fuels, like hydrotreated vegetable oil, is critical to the company achieving its 2030 near-term targets.

“As the construction industry is heavily reliant on diesel, the transition to electric heavy machinery and plant will take time – beyond 2030,” said Hynes. “Hydrotreated vegetable oil is widely available in other parts of the world at price parity and is the solution Laing O’Rourke is using in the United Kingdom to reduce scope 1 emissions.”

The METRONET Byford Rail Extension project was the first project in Western Australia to trial the use of renewable diesel. The renewable diesel is powering four onsite pieces of equipment with HVO100. The trial is being run in partnership with METRONET, WA’s Department of Transport, and Curtin University, which will undertake studies to understand implications for fuel efficiency, emission reduction and impacts on engines.

In New South Wales, the St Marys Station footbridge project team worked with subcontractor AnewX to trial HVO100 in their plant and equipment. To date, positive outcomes have been reported, with consistent engine performance and seamless transitions between fuel types.
