as the air travels through, the tiny holes provide an enormous surface area, meaning a high proportion of the co2 touches the surface and is absorbed. steam is then used to wash out the co2 which is processed and stored, ready for local use. this can then start its work over again. three commercial trials are already under way, but this solution is relatively small beer. perhaps one of the best technologies at solving the carbon problem is nature itself. i ve come to brynau wood in south wales, one the last patches of a once enormous ancient woodland. today, a reforestation project is under way. many countries have committed to planting more trees to soak up co2 but my guide gwyn says the mix of trees planted is crucial to success. when there is a mixed amount of tree species within a forest, so the more
in from a new us start up. we can provide co2 for large food packaging plants, all the way down to a small machine air to pull all the c02 right out of the air from inside the restaurant or bar right to the soda gun or the tap. they do it by using these cubes with thousands of tiny holes through them. the whole thing is coated in a chemical that absorbs c02. as the air travels through, the tiny holes provide an enormous surface area, meaning a high proportion of the c02 touches the surface and is absorbed. steam is then used to wash out the c02 which is processed and stored, ready for local use. this can then start its work over again. three commercial trials are already under way, but this solution is relatively small beer. perhaps one of the best technologies at solving the carbon problem is nature itself. i ve come to brynau wood in south wales, one the last
