Algae – boon to farmers and a solution to global warming
You are at: Oilgae Blog.
CSIRO scientists are putting the humble algae to work as a source of biodiesel and the signs are very promising. With algae made up of a third oil, a third carbohydrate and a third protein, it was an ideal raw material for producing biodiesel and ethanol.
Dr Beer said theoretically all of Australia’s diesel supplies could be produced from ponds covering just 10,000 hectares. The study found the establishment of a 500-hectare algal biodiesel plant in a rural area might create up to 45 jobs and provide opportunities to diversify in the agricultural sector.
While the technology was relatively simple, more research was needed, Dr Beer said.The next step was to build a pilot plant to see if the concept was commercial and viable and at what prices.
Like any crop, more work was also needed to identify the best species of algae to use and the conditions required for maximum yield. One challenge was to work out how to prevent other less productive algae taking over a pond, Dr Beer said.
