Notes to Editors:

Hydrodec Group plc is a clean-tech industrial oil re-refining group with operations in the USA.

Hydrodec's technology is a proven, highly efficient, oil re-refining and chemical process principally targeted at the multi-billion US dollar market for transformer oil used by the world's electricity industry. MarketsandMarkets forecasts that the global transformer oil market is expected to grow from USD 1.98 billion in 2015 to USD 2.79 billion by 2020 at a CAGR of 7.14%.

Used transformer oil is processed 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 (polychlorinated biphenyls), a toxic additive banned under international regulations.

In 2016 Hydrodec received carbon credit approval from the American Carbon Registry ("ACR"), enabling its product to be sold with a carbon offset and creating an incremental revenue stream. The Group is now generating carbon offsets through the re-refining of used transformer oil, which would otherwise ordinarily be incinerated or disposed of in an unsustainable manner. This is a highly distinctive feature for the Group, confirming (as far as the Board is aware) Hydrodec as the only oil re-refining business in the world to receive carbon credits for its output. This is a significant endorsement of the Company's proprietary technology and standing as a leader in its field.

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