Mixotrophic microalgae cultivation using food processing waste
Innovative use of food processing waste as a carbon source for mixotrophic microalgae cultivation enhances biomass production, CO₂ sequestration, and reduces environmental impact. This sustainable approach leverages nutrient recycling for cost-effective biomass yields.
Overview
This solution leverages the innovative use of food processing waste as a carbon source for the mixotrophic cultivation of microalgae. By combining photosynthesis with organic carbon uptake from food waste, this approach enhances biomass production and CO₂ sequestration. The process not only boosts microalgae growth but also reduces environmental impact by recycling nutrients and treating food waste simultaneously, making it a sustainable and economically viable solution.
Technical specifications
