Final Project

It seemed like a good idea at the time…

So, originally I had chosen to work with homemade bioplastics. I thought I should create something useful, something i needed. So, I decided to go with a set of cutlery that i would mold out of bioplastics that I made at home. Seemed easy enough. But I had nothing but problems.

To start, I did research into different recipes of bioplastics, especially hydrophobic bioplastics which could be used for eating, etc. I ended up with this recipe. It seemed easy, but it wasn’t. I had constant problems with the exact formulations, and it took days to cure. I thought that I would soon find a formulation that would work, but it either came out too gooey or so brittle it cracked. I couldn’t seem to get a middle-ground area. It all came out garbage.

I’m not really sure what i was doing wrong. The mixture, the oven maybe, I’m not really sure. I tend to also do this with food a lot, so perhaps i should have anticipated problems. What’s more, I was almost out of money for my project. With so many bad batches, I thought I should instead use a material that was easier to work with, so I made a last-ditch effort to make epoxy molds and then cast in clear acrylic.

This also went poorly.



In the end, perhaps because I didn’t use enough Vaseline or something, But molding from epoxy turned out to very problematic– and unfortunately ultimately too expensive to try again, as I had run completely out of money. So this didn’t work out, and now I’m broke.

Fascinating Material

After watching the presentation in class, I was very interested in the idea of home-made bioplastics, and the possibilities for household use. I began watching several videos regarding corn starch-based and milk-based homemade bioplastics recipes. At the same time, I was considering what I might make.

What Purpose?

I began searching around for what sort of things could be made of this material, but i kept coming across items like jewelry or utilitarian items like storage crates, blended-material bags, and other things i didn’t find particularly useful to me. So, then I thought, I should create something I need. And suddenly I had my idea.

Need To Eat

I’m moving soon, and my roommates have already moved out, taking nearly everything with them. I have one pot, a cookie sheet, a wooden spoon, and absolutely no cutlery. So, instead of going out and spending a bunch of money I don’t have on a new set of cutlery, I’ve decided. to create my own, designed how i want.

It didn’t take long to find a good amount of video instructions on how to mix various bioplastic recipes. After looking around, I found this one pretty easily. I think it has also been linked here in another post.

How to Make Corn Starch Bioplastic

I chose this method because I had tried the milk-based method and, well, it didn’t go well. Actually, it caught fire and ruined a pot. I decided to not take pictures. Besides, it’s more complicated and not necessary for my project. So, for my next attempt, I’ll be trying the cornstarch method.
