These modular garden tiles ("Lifewall" tiles) were created by the Spanish firm Ceracasa, and they're designed to support a variety of different plants and drip irrigated for water efficiency. And because they're modular, the 1sq.m (10.8sq.ft) can be placed in any pattern or design you want! But that's not all: Lifewall tiles were designed to work in tandem with another Ceracasa product called Bionictile, which sucks pollution out of the air and converts it into fertilizer for the growing, living wall.
Tests show that Bionictile ceramics can decompose 25.09 micrograms of Nitrogen Oxide per m2 per hour, which means that if 200 buildings incorporated ceramic BIONICTILE, 2,638 million cubic meters of air per year would be decontaminated.
The product is now being marketed globally. Read more about it (in Spanish) at CeraCasa and at Inhabitat.
