Warwick quarry develops new explosive free of fossil fuels
USING fossil fuels in quarries and mines could be a practice of the past with a Warwick quarry developing new explosives that would eliminate the use of the fuels.
The experiments conducted at Braeside Quarries earned the company an IQA gold environment award in October.
Independent owner Joanne Payne said it was the first major award the company had won as an independent organisation.
"It means that it doesn't matter if you're a big company or a small company, you can make a contribution to the environment,” Mrs Payne said.
"Quarrying is a very destructive type of industry and we need to find ways to make it more environmentally friendly and sustainable for the future.”
The explosive uses recycled rubber as a safe alternative to ammonium nitrate fuel oil and emulsion products.
Mrs Payne said the company started the experiments when they discovered the product's patent had lapsed.
Braeside Quarries took up the patents and worked with Chip Tyre, a crumbed rubber producer, to conduct trials.
Mrs Payne is also the general manager of Sequel Drill and Blast, which will market, store and deliver the final product, Mohrpower.
Mrs Payne said the explosive could create a massive change in the industry, as existing explosives were mixed with diesel fuel.
"We hope to in the future be able to commercialise the product so other businesses can reduce their fossil fuel usage,” she said.
Braeside Quarries has been operating on the New England Highway since 2009, starting as a paddock and being transformed into an operational quarry producing construction materials.
