Overview
Bioplastics
Cellophane is reformulated cellulose (wood), produced via an acid and base dunk of sawdust. This may be used in glazing. Car bodies may be made; the original car bodies for Ford were soybean-derived bioplastics.
Polylactic acid (PLA) can be made by fermenting starch or with hay in silage.
Mycelium can be placed in a mold with grain husks, wheat straw or any of a wide variety of other biomass (with different end product results) and be made into a variety of useful products, including a durable closed cell foam substitute.

Open Source Extruders
- Precious Plastic - prototype filament maker. Note that the hopper feed mechanism appears to be robust, so that regrind can be used readily.
Plastic Lumber Version Of the Precious Plastic Design
- Compare to Lyman Filament Extruder, which works well with pellets, but it is not clear if it would work robustly with regrind.
Co-Extrusion
Do different plastics mix well for making 3D printing filament? Yes, there are good combinations shown at [1]
- Good examples: PC/PET, ABS/PVC. For PC/PET - that could be a good combination mixing best properties of both.
