- bsilvereagle 5y agoThere are a growing number of companies selling algae-based CO2 scrubbers. You grow algae and force air to bubble through it. When the algae fully grows you can harvest it to eat or compost. However, you need to really run the numbers to see if the particular volume of algae is sufficient to clean the levels of CO2 you’d like to. In my case, I’d need ~20 of these to negate the CO2 generation in the space. https://algenair.com/ https://algenair.com/
