How did it come to the point that humankind builds ever bigger and higher houses? Spends more and more material for them and after no one wants to maintain those buildings any more they get dilapidated and eventually become ruins, standing there for all to see their obsolescence. No-one cares where the materials came from as long as they are cheap enough. Before, the buildings were stones and unpainted wood – easy to recycle. Next, it was bricks, cement, steel, and the facades were mortar – the recycling could still be done at least by grinding. Now, with this sustainability craze people started insulating the facades with a thick layer of Styrofoam insulation glued to the material the walls were made of. Sometimes, if the walls aren't dry enough before the insulation works, black mold starts growing on the whole façade through paint. Now, this combination of bricks, cement, Styrofoam, and paint doesn't seem to be so easily recyclable. So, what's going to be or how it’s going to look like after those buildings become obsolete? Some new materials separation process, maybe? Or, is this combination going to be a material for the “warm bricks” of the future?
