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 c02 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 biodiverse we have in terms of what s above the ground, the more biodiverse is below the ground and the more carbon ends up in the soil, where it is stored for a very, very long time. so does he think nature alone could lead us to carbon neutrality? this is a recent plantation. there s around about 15 20 different shrub and tree
so we have a 2 stage process. in the first stage, we blow air through. co2 sticks on the material, they are purified air so air without co2 or with very little co2 leaves the box. when the filter s full, we close the door and start heating. we heat up the collector up to 100 degrees, co2 is released and we take it out. once the filters are cleaned, the carbon capture can start all over again. 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.
