If you are looking for a material with a natural feel and high degree of freedom of shape then Treeplast might be a good alternative. It is natural renewable and biodegradable, originally made from wood chips (50%), with crushed corn and natural resins, it is now available with several recipes for different applications. There is a biodegradable version available that breaks down in water in a few hours or in 4-6 weeks in the open in grass/sand.

The raw materials are extruded to granulates, which can subsequently be processed in traditional plastic-processing machines like for instance with injection molding or extrusion. The end product can be bonded, finished and coated like wood.

The material is skin-friendly and non-electrostactic and has, unlike for instance PLA, a natural feel similar to wood.
