Buildings Made of “Moss-Growing Concrete” Could Remove More CO2 and Air Pollution than Thousands of Trees

Researchers have developed a “living concrete” that grows moss, lichens and fungi that could turn city buildings into giant air purifiers

Spanish researchers have developed a porous, acidic concrete that acts almost like soil for moss, lichen, fungi and other drought-tolerant vegetation. They are using the material to construct prototypes of office building capable of sucking more CO2 and pollution out of the air than thousands of trees, while emitting fresh oxygen for us to breathe. A moss-growing bench in London alone does the work of 275 trees, imagine what a whole building made of the stuff can do.
