International construction giant STRABAG has initiated a landmark biodiesel pilot project in Oman in partnership with Wakud. The collaboration represents a critical step toward lowering the carbon intensity of construction operations and fostering the adoption of alternative fuels across the Sultanate's industrial and contracting landscapes.
The project is designed to evaluate the technical and operational viability of B7 biodiesel in heavy construction machinery under real-world site conditions. This initiative aligns with Oman’s broader energy transition strategy and the national mandate to reach net-zero emissions by 2050.
According to STRABAG Oman, the pilot is scheduled to operate for approximately three months. During this period, the machinery will run under two-shift conditions, consuming an estimated 27,400 litres of B7 fuel. The initial trials focus on a Caterpillar 966GC wheel loader, with performance data being closely tracked to inform future decisions on expanding the program to a wider range of equipment.
B7 biodiesel consists of a blend featuring up to 7% biodiesel combined with conventional diesel. STRABAG identified this specific blend as a viable starting point because it adheres to the EN 590 diesel standard, provided it meets quality specifications and manufacturer requirements. The company intends to analyze fuel consumption rates, engine efficiency, operational reliability, and maintenance needs to ensure that productivity remains uncompromised.
Significantly, STRABAG estimates that roughly 50% of its current construction fleet in Oman could be compatible with B7. However, the wider rollout remains contingent on the pilot results, machinery compatibility, and the establishment of a reliable fuel supply chain. This trial is among the first of its kind in Oman to test biodiesel in heavy machinery directly on active construction sites.
The move holds substantial weight given that the building and construction sectors contribute nearly 38% of global carbon dioxide emissions. For STRABAG, this pilot is a component of a larger sustainability framework involving over 200 innovation projects globally. The group has set science-based targets to reduce absolute Scope 1 and Scope 2 emissions by 42% and Scope 3 emissions by 25% by 2030.
Looking forward, STRABAG indicated it may explore higher biodiesel blends and other low-carbon fuels if the initial pilot proves successful. The company noted that broader commercial success in the region will depend on improved fuel availability, competitive pricing, and the diversification of reliable suppliers.
