A Comparative Cost Analysis using Dust Suppression on Roads

Global Road Technology (GRT), a Queensland based company, operating internationally, manufactures products and provides turn-key solutions to the market for dust control, soil and ground stabilisation with a particular focus on roads. They offer a specially formulated liquid polymer (GRT7000) engineered for use in dust suppression during civil construction. GRT7000 concentrate is diluted with water when loaded into a water tank, then applied to a dusty unsealed road using standard spray equipment.

GRT has engaged Deloitte Touche Tohmatsu (Deloitte) to provide a comparative evaluation of the cost in relation to conventional water spray dust suppression methods (Conventional Approach) and dust suppression using GRT7000 (GRT Approach) under comparable conditions.

Deloitte has engaged the services of SMEC Australia Pty Ltd (SMEC), a civil engineering firm, and Project Support Pty Ltd (Project Support), a specialist quantity survey consultant, (together Technical Advisors) assist with the identification of the appropriate cost base and operational assumptions for the Conventional Approach to support the financial analysis.

Key Assumptions in the Analysis

The cost estimation and comparative financial analysis have been undertaken on the basis of a number of assumptions regarding the operation and underlying unit costs. Project Support together with SMEC have developed input assumptions and populated a cost estimation model Expert Estimation. GRT have provided the input assumptions for the use of their product including the cost and application cycle and rates.

Typical savings compared to 4 water applications per day on 10km road being 10km away from a water source and with water costing $0.30 / kl for a 24 month period:

Water Savings

More than 95% saving on water

Water based dust suppression requires constant re-watering to be effective.  Water is fast becoming a scares and vital commodity. Applied water quickly evaporates instead of being available for more critical requirements such as agriculture. For the above scenario, you will save more than 229 000 000 litres water by using GRT Polymer Seal.

Greenhouse Gas Savings

More than 98%

Water needs to be applied by heavy vehicles having to constantly traverse the road.  These vehicles are heavy polluters.  Save for the pollution, heavy vehicles contribute to traffic and maintenance demand on the road. For the above scenario, you will remove 537 000 heavy vehicle kilometers off your road, equating to 500kg greenhouse gasses.
