Filtration system converts CO2 into biodiesel

Engineers in Wales have reportedly developed a filtration system that converts carbon dioxide emissions into a waste product that can be converted by genetically modified algae into biodiesel.

The system, called a Greenbox, could replace the muffler on a conventional exhaust although it is too large to fit onto an existing car exhaust. It could also be used for larger vehicles or even buildings, its creators suggest.

In test over the last two years, engineers Ian Houston, John Jones, and organic chemist Derek Palmer found that the Greenbox could reduce carbon dioxide emissions by 85-95%.

They discovered the technology, the exact makeup of which remains a secret, when looking at ways to increase fish farm algae with carbon dioxide. They have suggested that algae processing required for the UK 's thirty million cars would take up an estimated 1,000 acres.

The engineers are seeking further investment into their new device and have set up a new company, Maes Anturio Ltd, to develop the technology.
