Notes to Editors:

Hydrodec's technology is a proven, highly efficient, oil re-refining and chemical process initially targeted at the multi-billion US$ market for transformer oil used by the world's electricity industry. Spent oil is currently processed at two commercial plants with distinct competitive advantage delivered through very high recoveries (near 100%), producing 'as new' high quality oils at competitive cost and without environmentally harmful emissions. The process also completely eliminates PCBs, a toxic additive banned under international regulations. Hydrodec's plants are located at Canton, Ohio, US and Young, New South Wales, Australia. Hydrodec recently acquired the business and assets of OSS Group, the UK's largest collector, consolidator and processor of used lubricant oil and seller of processed fuel oil, with a national network of oil storage and transfer stations, currently serviced by a fleet of more than 90 trucks which collect used oil and other garage workshop waste from over 30,000 customers. Used oil is converted into processed fuel oil at OSS's plant at Stourport and principally sold on to the UK quarry and power industry.

Hydrodec's shares are listed on the AIM Market of the London Stock Exchange. For further information, please visit www.hydrodec.com.
