CC01 Chrondus Crispus (Carrageenan)
NOTE: This recipe is poorly documented. Do not expect to gain the same results by following my steps. Even I forget how I made this one. And that is a shame because this is really good bioplastic. Instead, try making CC02.
Chrondus crispus is well known for its high carrageenan content. To make this, I followed the abundant online tutorials on how to make Chrondus crispus gel, then casted that gel into a mold.
Procedure:
Blend the seaweed in water (choose your own quantities: 150mL of water and 3g seaweed will make a LOT of bioplastic.)
When it is homogenous, put it into a pan or cooking apparatus.
Heat at 60C for 2-10 minutes, depending on quantity. You will lose some water in this step and the gel will become thicker.
Once the mixture is feeling thicker, cast it into a mold or a flat item.
Let dry for 5 days.
Done!
Note that I did a horrible job of casting the bioplastic, and that is evident!
Before drying:
The film-like ball of stuff is what dried in the heated pan.
After drying:
Results:
Overall, I would call this a large success. This is because I can make bioplastic out of raw material, instead of doing lots of processing, which costs money and has a large environmental impact. I look forward to continuing this research by creating a stronger film in the future.
