Biodegradable plastic is usually made of natural plant materials. Maybe the most popular, well-known material is corn. Since it’s a fresh idea to produce biodegradable plastic with potato, I’d like to introduce it to you in this post. The Potato Plastic can be molded under compression so it opens up many design possibilities.
Plastic made of Potato Starch
What is biodegradable plastic made of? The answer can vary (or become various) nowadays.
If you’re a 3D printer user, you may think about PLA biodegradable filaments. Lots of PLAs are produced with corn starch but there’re other interesting materials. Here I found Potato Plastic (The James Dyson Award Winner) which I described shortly below.
- Biodegradable plastic made of potato starch and water
- Can be decomposed to nutrients for the soil in 2 months
- Can be molded under compression (thermoplastic), good for products like cutlery
More responsible biodegradable plastic
Now we all know we create too much waste. Since I’m still selling my plastic products, I feel guilty and want to make a change from the next product – that’s why I’m interested in biodegradable materials.
I agree with the Potato Plastic‘s creator that achieving big changes in the society comes with taking small steps in the right direction. Although adopting biodegradable plastic doesn’t solve all plastic problems, it’s worth to try and start a possible step.
Actually there’s controversy if the biodegradable plastic is “really” biodegradable. Some of them are not fully decomposed for the time they say it’s supposed to be. Some of them are not compostable at home so we’re confused about where we can throw them away (with organic waste or no? with recyclables or no?).
Anyway Potato Plastic uses seaweed to bind potato starch, to let it actually end up in the soil. Therefore I support the creator’s idea to make single use biodegradable products for fast food industry.
Potato Plastic won The James Dyson Award in 2018 and I’m wondering if it makes a progress in two years. I hope it does with proper marketability.
Natural substitute for single use plastics
Can biodegradable plastic solve the problem of disposable plastic products? It could be one of the possible solutions, especially with “not providing single use products” policy. At least we can use plastic far less, if we don’t have most of them at the fast food restaurants and replace some of them by potato, corn or other natural plant plastics.
And there’re also PLA biodegradable filaments – I’m using this kind of material for my 3D printer.
The posts in 3D Prints are usually focus on my printing experience but I’m going to write about the material as well, maybe in a month at the latest.
