Wool Carpets also know as Biocarpets, as the name indicates are bio-degradable to the extent that they contain all natural components which in itself are Bio-degradable.
It will not biodegrade on its own on the wooden, cemented, tile or any other kind of floor. When disposed of after its useful life, its natural materials will decompose in other natural components and plant nutrients like nitrogen, potassium, magnesium etc. This replaces the need to put additional organic materials in soil as biocarpets can serve as plant nutrients and can be used as soil amendment either directly or after compositing.
