Biofuel from Microalgae: A Sustainable Alternative to Fossil Fuels<br /><br />By: Asst.

Unlike traditional biofuels derived from food crops, microalgal biofuels do not compete with food supply chains or require freshwater resources.<br /><br />The production process involves cultivating microalgae in ponds or photobioreactors, harvesting biomass, and extracting lipids for conversion into biodiesel or bioethanol. Some strains also produce hydrogen or hydrocarbons directly, offering multiple pathways for energy recovery.<br /><br />Microalgae can also absorb CO₂ during growth, making their use carbon-neutral or even carbon-negative. They can grow using wastewater and sunlight, making them ideal for integration into circular economy systems.<br /><br />While current challenges include high production costs and energy input, ongoing research is focused on genetic engineering, process optimization, and scaling technologies to make algal biofuels commercially viable.<br /><br />Al-Mustaqbal University – The No. 1 Private University in Iraq
