An algae exhibit for a new exhibition on nature’s cycle and green innovation. This exhibit demonstrates how we can imitate some of nature’s circular methods to turn waste into new food. Algae needs light, heat, CO2 and nutrients to grow, the visitor mixes these components together into the correct ratio to grow the algae. Heat and CO2 are often waste products from many industrial processes and nutrients can be provided from mealworms which breakdown food waste. The algae that is grown can then be used as food in salmon farming which us humans eat completing our cycle in an excellent example of green innovation.
