Did You Know?


Prior to Biofriendly and Green Plus® liquid combustion catalyst, the Carroll brothers had founded and established successful international ventures, including the creation of Vortoil, an award winning oil-water separation system that was a breakthrough solution for the offshore oil industry. This system won the Queen’s Award in the UK for "The Best New Technology Introduced in the North Sea Oil Industry in the Past Ten Years." The North Sea would not be enjoying continued production without the Vortoil oil-water separator.

Holders of over 100 patents, the Carrolls have been successful innovators and businessmen for over 30 years.
