FREQUENTLY ASKED QUESTIONS
HOW DOES THE RESIN CAPTURE CO2?
To absorb carbon dioxide, our design utilizes the difference in the partial pressure of CO2 when the resin material is wet versus dry. When at 0% CO2 saturation, the adsorption capacity of the resin material in a wet state is 100 fold that of its dry state. Using this moisture swing mechanism, the resin material can collect CO2 while wet until the saturation state is reached. The CO2 remains on the resin after evaporation, until the CO2 is dissolved in water. Upon rinsing with water, the resin material is "recharged" and ready to capture CO2 again.
WHAT IS THE LIEFESPAN OF THE RESIN?
Because of the extremely high efficiency of ion translations, the resin material is regenerative with a lifetime effectiveness of about 100 years. Material tests are being conducted to determine the moisture and sun exposure limitations.
HOW MUCH CO2 IS CAPTURED?
Our initial tests indicate the potential for 172kg of CO2 capture per year per unit. A tree can absorb as much as 21.77 kg of CO2 per year. In other words, testing indicates that our device has the ability to capture nearly 8 times as much CO2 as mature trees with a significantly smaller surface area.
WHAT IS BIOMIMICRY?
Biomimicry is an approach to innovation that seeks sustainable solutions to human challenges by emulating nature's time-tested patterns and strategies. Visit https://biomimicry.org/what-is-biomimicry/ to learn more.
HOW IS extrACTION BIOMIMETIC?
Our system was inspired by biological research on the function of rubisco, a molecule that captures CO2 for photosynthesis, and carbonic anhydrase, the catalyst in converting CO2. We have emulated these strategies found in nature in our device which captures carbon dioxide, and converts CO2 into a carbon-rich solution.
