1. A biodegradable synthetic leather, comprising:
a biodegradable layer comprising a mixture of a plastic and a biodegradable additive, the biodegradable layer having a first surface;
a backing layer comprising bamboo fibers, the backing layer having a first surface and being configured to provide mechanical support to the biodegradable layer;
an adhesive layer between the first surface of the biodegradable layer and the first surface of the backing layer for bonding the biodegradable layer to the backing layer; and
a biodegradable coating comprising another biodegradable additive directly on a second surface of the backing layer, the second surface of the backing layer on an opposite side of the backing layer relative to the first surface of the backing layer,
wherein the biodegradable coating is formed by:
dissolving a powder of the another biodegradable additive in a solvent to form a second mixture,
applying the second mixture onto the second surface of the backing layer, and
wherein the biodegradable additive of the biodegradable layer and the another biodegradable additive of the biodegradable coating are the same biodegradable additive.
