Algae biofuel using CO2 from a whisky plant ! Posted by Veronica on Sun September 26 2010 09:34:49 PM 4

The Glenturret Distillery in Perthshire home to The Famous Grouse Whisky percolate CO2 made during the whisky distillation through a microalgae bioreactor.


 Each tonne of microalgae absorbs two tonnes of CO2. Scottish Bioenergy, who run the project, sell the microalgae as high value, protein-rich food for fisheries.

 In the future, they plan to use the algae to produce other high value products and feed the residues to an anaerobic digester.


Anaerobic digestion is the process where bacteria and other micro-organisms break down plant and animal material in the absence of air. The product of anaerobic digestion is a combustible gas, which Scottish Bioenergy plan to use to generate renewable heat and power for the distillery.

 Anaerobic digestion is a wet process so there is no need for water removal, reducing the carbon footprint associated with harvesting the algae.


'In the short term, microalgae will be made into high value products, but increasingly are expected to help in the remediation of wastes,' says Dr Claire Smith, algae lead for the NNFCC  the UK's National Centre for biorenewable fuels, materials and technologies.

'Energy opportunities will develop through using algal residues but are likely to be smaller, more local solutions, rather than the larger scale facilities we see abroad.'
Microalgae offer a real solution to the challenges of climate change and can provide additional environmental benefits. 

The opportunities for UK companies to develop this budding technology are tremendous, but so remain the challenges.

My questions are the same as what Alan Schafaer asks regarding Co2 absorption in a coal power plant.
How much land is required for this ?
What is being done in the nights ?
