Experiment with future plastic alternatives (V4)
We are Marina and Jannis researching sustainable alternatives to plastic.
We’ll share our process and sources here as we go and are open for any help! 🙂
Let’s find a solution for a plastic-free(er) future!
… lignin is a pretty “plastic-like” natural resin … and actually a “waste product” from paper production 😉
Hey birls and goys, thanks for the replies! They are very helpful!
@frogfall: Materiom is pretty much what we thought this community was missing, so that’s perfect. We can’t wait to feed it with more recipes. Thank you!:)
We spend the last week researching and setting up a mini-lab in the workspace (check out the Marina’s MiniLabDance and our chimney;) ), gathering utensils for first material try-outs. As a starting point for now we decided to work with food scraps since it seems to be the most approachable waste stream and it could be easily accessible for everyone everywhere.
As a start we extracted some starch from potato peels and separated gluten and starch from wheat flour. Wheat seems to work really well and the gluten is a pretty funny flexible, slimy material and as we popped a bit of it in the oven with dinner, it actually formed a pretty nice ball-thingy. The potato peels didn’t make a lot of starch, since most of the starch is in the potato itself , but we want to try to use them as a whole now. Maybe like these guys: https://www.chipsboard.com/
Moreover we are putting our heads together with our chefs to make edible materials to kill single use plastic waste streams at festivals and things like that, since Dave stumbled across these fabulous plates: http://biotrem.pl/en/
We are really excited to start more experiments next week and we’ll share more of research material we gathered in the coming days.
Let us know what you think!

Oh and here are some pictures of the gluten!
Thanks @dasjannis – I look forward to seeing the recipes.
This is a topic I was interested in for a little while over a year ago, and tried a few recipes (without much success).
I did some tests with boiled linseed oil – trying manganese dioxide (manganese IV oxide) as a catalyst to promote cross-linking – but the reaction was so slow that my samples are still “rubbery” a year later!
Another interesting substance is soy protein isolate – a powder that is sold as a food supplement for body-builders. I came across a paper that claimed that it could be “cooked” after mixing with magnesium oxide (which is sold as a horse feed supplement). I did a few tests, but it came out rather brittle. I also tried using the mixture as part of a composite with some fabrics – but, again, found it too brittle.
I might have another go if I can find the time 😉
I think this is amazing what you guys are doing. I worked for a milk company years ago and the automtive industry was our biggest customer they used a byproduct of milk called casein. This was used in dashboards because it can easily be formed.
have a look at this youtube clip. I will add a recipe in the database when i find one suitable.
That’s interesting, plastikfantastik, about automotive uses of casein. The article below suggests it isn’t used much nowadays (or at least the formaldehyde hardened version)
History of casein plastics
Maybe the compound they were using was without the formaldehyde, and used some other hardener.
I guess the video is basically of cheese-making 😉 (see curdling)
A couple of references for Soy-based adhesives:

Good range of substances outlines in the following (open access) paper. It includes lignin, as mentioned by vdx2
