Mechanical methods: An oil press is the simplest available method to press the dry biomass to extract oil. Oil presses are successfully used for the extraction of oil from crop seeds (e.g., sunflower, canola, and olives). In the case of algae, the biomass requires drying prior to pressing it through the press, which is a significant cost making this option less cost-effective.
