Spanish Researchers Develop Photobioreactor to Produce Algal Biofuel

In Spain, University of Alicante researchers have patented a new device, consisting of a photobioreactor, that allows more efficient cultivation of microalgae as raw material for biofuel and other high-value products.

The prototype designed by the Research Group in Polymer Processing and Pyrolysis allows mass production, less cleaning and maintenance operation, better use of carbon dioxide, better light transfer and it is easily scalable for larger production. According to the research group, the unique design of this new device addresses the difficulties in microalgae cultivation for biofuel and industrial substances, citing the high cost of production that hinders commercial viability.

Apart from biomass for biofuel production, microalgae provide raw materials that can be used to produce substances of high value in food, pharmaceutical and cosmetic sectors. Depending on the species, products such as antibiotics, polyunsaturated fatty acids, enzymes, proteins, vitamins, triglycerides or antioxidants, can be derived from microalgae.
