DuPont Australia’s groundbreaking work in reducing dust emissions from coal trains, improving air quality in local communities, has been recognised with two prestigious industry awards – the Australian Mining Prospect Awards award for Excellence in Environmental Management and the Australian Bulk Handling Awards award for Dust Control Technology.

The Australian Mining Prospect Awards were held in Sydney on Wednesday 11 November and The Australian Bulk Handling Awards on Thursday 12 November.


The awards came as a result of a joint project with Anglo Coal, which saw the coal dust emissions during rail transportation reduced by 50 to 90 percent, depending on the actual conditions and coal transported.


‘Dust emissions from coal trains are a serious problem for the mining industry and a constant source of compliant for communities near the rail lines’, said DuPont Technology Centre Manager, Dr Leong Mar. ‘Australia’s hot, dry climate significantly increases the potential for dust emissions during the trip from the mine to the port.


‘DuPont worked closely with its partner, Anglo Coal at their Callide Mines, to provide a solution that incorporated a specially designed wagon spray system that treats the surface of the coal load with a DuPont™ Dusgon® dust suppression agent. The rail wagon dust suppression system is seamlessly integrated with normal operations and provides tangible benefits to the workers, local community and the environment.’


The improvements were verified by independent environmental consultants who monitored the coal dust emissions from the trains treated with DuPont™ Dusgon® dust suppression agents. The dust emissions from these trains were found to have been reduced by 50 to 90 percent compared to untreated trains.


DuPont Australia Managing Director, Hutch Ranck, says the award reflects the company’s commitment to developing products that protect people and the environment.


‘DuPont is proud to have partnered Anglo Coal to provide a solution that benefits the environment and the industry.
