Product Description:

This is a fully automatic solar-powered carbon absorption device. The solar panels first charge the wet battery. The air pump injects air containing carbon dioxide into the lime water, which undergoes a chemical reaction to produce calcium carbonate, which is then filtered by a water pump. To maintain concentration, a pH meter controls the replenishment of lime powder. The resulting calcium carbonate can be used to make concrete, among other things, turning waste into treasure and reducing the impact of climate change.
