    There was a guy that made a non-toxic and edible plastic called Starlite. They fed it the dogs and horses.

      You can use also the website materiom for other open source bioplastic and biomaterial recipes. Try it out and experiment until you find a ratio you like!

      Oh I know the feeling- I felt very discouraged when I first started and stopped for 2 years. That's why I made this video! I post all my experiments @theseaweedgirl on instagram :)

    I'm thinking about how pre-petroleum-plastic people would make tools like forks, spoons, and combs from animal horn which was boiled in oil or soaked in water to soften it so it could be molded. It has a texture not too far from plastic from what I've heard and it biodegrades, which is why we don't have a ton of really really old examples. They also made windows from horn too!
    I'm wondering if bioplastics made from algae can be a more scalable alternative to petroleum based plastics and to horn for these sorts of things.

    So, that is fascinating and I have lots of questions. Does it last a long time? Does it dissolve in any common liquids? Is it flexible? How thick a piece can you pour? Can you shape/melt it? I’ll have to try it out and find out!

    @lennybogart 11 หลายเดือนก่อน

    So, if I want to make a plastic that is flexible after a certain temperature but then, sets again once it cools, I need to choose a plasticiser that only melts past a certain temperature and sets again below that temperature?
    Am I right??

    Hi Ms. Kathryn. I am located here in the Southernmost of the Philippines, specifically in the BARMM region. We are the top producer of seaweeds here in the Philippines and I would really love to focus my thesis for my master's degree in Chemistry on seaweeds with the aim of furthering its application. I am fascinated with now I discovered other applications of bioplastic on the manufacturing of utensils, in replacement of synthetic plastics. Using bioplastics from seaweeds is obviously more sustainable. Where can i personally reach you? Hope you can give me insights. Thank you!

    Hi! This is a very interesting video. I stumbled across it while I was doing research for a material studies project based around bioplastic. I tried my own experiments, however, they all seem to shrivel up/ crumple and become distorted while also shrinking significantly. When I try to put something heavy on top to keep the bioplastic flat, the moisture becomes trapped and the bioplastic starts to develop fungi. Has this ever happened to you, and if so do you have any tips on how to prevent this?

    • @maggiesssss
      @maggiesssss 2 ปีที่แล้ว

      Although to be honest, a lot of the bioplastics I've tried to make also developed fungi without me even covering it. I've been using Agar Agar powder, glycerol and water in the recipe.

      @KathrynLarsen  2 ปีที่แล้ว +1

      @@maggiesssss agar is super prone to shrinking. You may need to add less agar, more plasticizer, and be aware of humidity when you pour- a dryer room results in more warping. You can also experiment with adding other starches or glues like fish glue, and seeing if that helps the shrinkage.

    • @KathrynLarsen
      @KathrynLarsen  2 ปีที่แล้ว

      Hi ! I just laser cut mine by hand. I think if you use a mesh, in many cases the bioplastic will bond with the mesh. You could also pour into a metal pan and use a dehydrator.

Alginate, agar and carrageenan kappa are extracted chemically from the seaweeds and while these are tasteless, it's because they've been isolated from the rest of the seaweed.
