- Hydroponic farming requires the circulation of nutritious water, the same as microalgae farming. Combining the same water source for both reduces the "amount of water to product" ratio.
- Microalgae require sun, while the sun can generate energy. Energy is needed for water circulation.
- Plant fertilizers are the second biggest industry after the pharmaceutical. Algae can be used as fertilizers.
