As news breaks that global carbon dioxide levels are at an all-time high, one scientist is developing “artificial trees“ to help cleanse the air and reduce greenhouse gas pollution. Columbia University’s Klaus Lackner has developed a carbon dioxide capturing material that acts as a powerful sponge – and it’s able to soak up CO2 faster than plants!

Lackner’s experiment resembles a miniature indoor greenhouse, with bamboo, cucumber, basil and house plants thriving inside. Hooked into the greenhouse with the plants is Lackner’s plastic resin-based material, which looks more like a shag carpet than a carbon dioxide siphon. The strands of plastic on the “carpet” act like mini CO2 magnets, and they bind to the greenhouse gas to form bicarbonate sale.

With the aid of a fan, the plastic resin works even harder, pulling 700 kilograms of CO2 from the air. High-powered machines made from Lackner’s plastic resin could make a real difference – ten million “artificial trees” could drop atmospheric concentrations by 0.5 ppm per year, which over time would help reduce the ever climbing greenhouse gas problem.

    So it just absorbs the CO2 rather than using it and releasing oxygen? Converting one waste to another waste doesnt help. I\’ll stick to plants.
