A team at the University of Tsukuba introduced a new procedure of harvesting energy and organic molecules from algae using nanoporous graphene and porous graphene foams. By developing a reusable system that can evaporate water at high rate without the need for centrifugation or squeezing. This research has a great potential for the application of producing cleaner, cheaper, and more efficient biofuels, vitamins, and chemicals.
In the fight against global climate change, algae biomass is a very exciting field of research, because they are photosynthetic microorganisms that convert light energy from the sun into energy-rich biomolecules. When algae are grown and harvested on an industrial scale, these molecules can be converted into a wide array of important compounds, including biofuel, medicines, omega-3 dietary supplements, and many other valuable bio-products. Algae are also able to absorb carbon dioxide as they grow, switching from traditional fossil fuels to biofuels holds the promise of slashing net greenhouse gas emissions. However, micro-algae cultures consist primarily of water at low solid content (0.05 – 1.0 wt%) and harvesting the organic material due to solid-liquid separation techniques usually requires multiple dehydration steps.
