Assistive tech for people that have trouble holding forks/spoons/etc. Made from my favorite lesser known material, polyhydroxyalkanoates, which is fully biodegradable in any biome. Anyone else making AT for people?

Cool. I've never seen PHA before. What printer are you using for it? Is it any harder to print with?

Wow, this stuff looks cool. "A drop of fossil energy use by 95% and greenhouse gas emission by 200% can be achieved by substituting petroleum-based polymers with PHAs.4 Therefore, PHAs have the potential to contribute to a green industrial evolution."

Oh that is very interesting! I guess the main way that they decompose is through PHA depolymerase--according to ChatGPT a lot of the species that have been tested in the decomposition of PHA are bacteria. It would be interesting to try inoculating some samples of PHA with different mushroom species as well. It would be really great if PHA could be fully-decomposed into proper food-safe compost.
