The Times – Using carbon dioxide to help grow veg

The fight against climate change took a fascinating new step on May 31 — carbon dioxide was sucked out of the air and used commercially to help grow vegetables. The Climeworks facility near Zurich in Switzerland soaks up carbon dioxide from the atmosphere and pumps the purified gas to a nearby greenhouse where tomato, cucumber and other plants are enriched in the gas, fertilising them by boosting their photosynthesis. The Climeworks operation is powered by a waste heat recovery facility, a renewable energy source, so it doesn’t add any of its own pollution.
