The growing interest in this field stems from the urgent global need for renewable resources and circular solutions to combat climate change and resource depletion. In contrast, closed photobioreactors offer greater control over environmental conditions, leading to higher productivity and purity, albeit at a higher initial investment.
Circular Economy and Sustainability in Oil Algae Production
A significant technological challenge lies in the harvesting and dewatering of the microscopic organisms, a step that currently represents a large portion of the production costs. Furthermore, algae cultivation can utilize non-arable land and saline or wastewater, avoiding competition with food crops for freshwater and fertile soil.
Additionally, the residual biomass, after oil extraction, serves as a high-protein ingredient for aquaculture and livestock feed, further enhancing the circular economy model of algae production. These organisms act as powerful carbon sinks, absorbing significant amounts of CO2 during their growth phase.
Circular Economy and Sustainability in Oil Algae Production
Technical challenges include developing strains that are both highly productive and resistant to contamination, as well as creating integrated biorefineries that can utilize the entire algae crop for multiple high-value products. Unlike higher plants, many microalgae can produce lipids—fats and oils—as a storage mechanism, often when subjected to specific stress conditions such as nutrient limitation or high light intensity.
