 Southern Oil Refining, Northern Oil Refinery The $65 million Northern Oil Refinery at Yawin near Gladstone opened in March last year as the first facility in Queensland that recycles waste lubricating oil back into base lubricating oil for reuse. It is the most advanced re-refining plant of its kind and uses cradle to cradle treatment of oil to ensure it is kept in productive use, lowering carbon emissions and delivering improved oil security. The plant can handle 100 million litres of waste oil a year, meaning all of Queensland's annual waste lubricating oil production can be processed through Gladstone, underwriting a new industry and local jobs.
