Last week, the temporary closing of Frankfurt's airport in Germany, due to bad winter weather, affected 8000 people. In order to fight the ice and snow, the airport used 700.000 litres of antacid to get rid of the three-day snowfall. This is an eco-friendlier option compared to aggressive salt or toxic chemicals, as the antacid is biodegradable and doesn't contaminate the groundwater. An excellent example of biomimicry, this antacid is like the one ants use to defend themselves, and also similar to the substance found in nettles, although the antacid used to defrost ice is made synthetically, without hurting any ants.
