Developed by Professor John Orbell and his team at Victoria University, the technology delivers emergency stabilisation that acts within minutes.

“Oiling of our wildlife is happening on a continual basis worldwide,” John says.

“Compared to the traditional approach of detergent-based treatment at rescue centres, our highly portable dry-cleaning method enables us to quickly remove the most toxic and corrosive oil components.”
