DUSTLOC™: A Smarter, Safer Dust Suppression Solution for Pilbara Haul Roads

The Pilbara is one of the world's most demanding mining environments. Extreme temperatures, heavy haul truck traffic, and long stretches of unsealed roads create significant dust management challenges for mine operators. Effective dust suppression is essential, not only for operational efficiency and equipment performance, but also for protecting worker health, reducing environmental impacts, and maintaining safe site conditions.

DUSTLOC™ has become a trusted dust suppression solution across the Pilbara because it delivers long-lasting dust control while meeting stringent environmental expectations, including use near sensitive drinking water catchment areas. DUSTLOC™ is a biodegradable lignosulphonate-based dust suppressant that is approved for use by both Rio Tinto and the Western Australian Department of Health, including use near drinking water catchment areas.

The Pilbara Dust Challenge

Mining haul roads are subjected to constant heavy vehicle movement, generating large volumes of airborne dust. Uncontrolled dust can result in:

• Reduced visibility and increased safety risks

• Higher water consumption from continual watering

• Accelerated road deterioration

• Increased maintenance costs for vehicles and infrastructure

• Increased environmental impacts and community concerns

Traditional water-only suppression methods often provide only short-term results, particularly in the Pilbara's hot and dry conditions where evaporation occurs rapidly.

How DUSTLOC™ Works

DUSTLOC™ is a pure lignosulphonate-based dust suppressant that binds fine particles together within the road surface, forming a stable crust that resists displacement from traffic and wind. Unlike water alone, DUSTLOC™ continues working after application, helping retain moisture within the road profile and extending the effectiveness of dust control measures. 

This results in:

• Longer-lasting dust suppression

• Reduced watering frequency

• Improved road stability

• Reduced loss of fines from the road surface

• Lower operating costs over time

Proven Performance Across Pilbara Operations

DUSTLOC™ has been supplied to Rio Tinto operations for more than a decade and is identified as the preferred lignosulphonate-based dust suppression additive across Pilbara operations. DUSTLOC™ is listed by Rio Tinto as DC1016 and has been recognised in Rio Tinto HSE communications as a preferred dust suppression solution. 

Its widespread adoption demonstrates the product's ability to perform in some of Australia's harshest operating conditions.

Key Operational Benefits

Reduced Water Usage

Water is a valuable resource in remote mining operations. By extending the effectiveness of each haul road treatment, DUSTLOC™ can significantly reduce the frequency of water truck applications, lowering water consumption and operating costs.

Improved Safety

Better dust control means improved visibility for operators and reduced airborne particulate exposure. Maintaining a stable road surface also contributes to safer haul road conditions and improved vehicle control.

Enhanced Road Performance

By helping bind surface fines, DUSTLOC™ assists in maintaining road integrity, reducing corrugations and minimising material loss caused by vehicle traffic and wind erosion.

Lower Maintenance Requirements

Reduced dust generation and improved road stability can lead to lower grader usage, fewer maintenance interventions, and reduced wear on mobile equipment.

Safe for Sensitive Water Catchment Areas

One of the most significant advantages of DUSTLOC™ is its environmental profile.

DUSTLOC™ is a 100% biodegradable dust suppression product and is approved for use near sensitive drinking water catchment areas. The Western Australian Department of Health have issued DUSTAC with an approval letter covering the use of DUSTLOC™ near drinking water catchment areas. 

This approval provides mine operators and asset owners with confidence that dust suppression activities can be undertaken while maintaining environmental stewardship and protecting important water resources.

For operations located near reservoirs, catchments, or environmentally sensitive areas, selecting an approved dust suppressant is a critical consideration. DUSTLOC™ allows operators to achieve dust control objectives without compromising their commitment to responsible environmental management. 

Supporting Sustainable Mining Operations

Modern mining operations are increasingly focused on sustainability, water conservation, and environmental performance. DUSTLOC™ aligns with these objectives by:

• Reducing water consumption

• Minimising dust emissions

• Supporting safer working environments

• Providing a biodegradable solution

• Being suitable for use near sensitive catchment environments

As the mining industry continues to pursue safer and more sustainable operating practices, products that deliver measurable operational benefits while meeting stringent environmental requirements will continue to play an important role.

Conclusion

For Pilbara mining operations, effective dust suppression goes beyond simply controlling airborne dust. The solution must improve safety, reduce operating costs, conserve water, and meet environmental expectations.

DUSTLOC™ has demonstrated its capability across Pilbara haul roads for more than a decade and offers a unique combination of performance and environmental responsibility. As a biodegradable lignosulphonate-based product approved for use by Rio Tinto and supported by Western Australian Department of Health approval for use near drinking water catchment areas, DUSTLOC™ provides mine operators with confidence that they can achieve effective dust control while protecting critical water resources.
