Japanese flower artist Makoto Azuma in collaboration with Unitika Ltd, exhibited a biodegradable green carpet at the Tokyo Fiber Sensware exhibition. This carpet is not just biodegradable, its also biological. The top layer of the carpet is composed of moss which grows and held together by the underlying fiber base. The fiber base is a made of Terramac,a plant-derived polyactic acid-fiber, which can decompose after 10 years.  Meaning that you cant pass this carpet to your grand children.

While it does look magnificent, the function of the carpet (besides capturing CO2) was not mentioned. It doesn’t seem to be the carpet you can lay on and spend a book with. Nor does it looks easy to vacuum and clean. You might need the gardener to clean this kind of carpet.
