Production of chitosan from brewery waste
After a material project with chitosan there was the question for other sources next to fishing waste. The material it self has some good characteristics. It is antibacterial, antifungal, biodegradable and recyclable. I managed to make some foils out of it and developed a packaging concept.
Asking for the source of chitosan I found some disadvantages. It is expensive, complex to produce and comes with long shipping from other continents.
You can find chitosan also in brewery waste, so i started to experiment with it. By using a paper from P. Pochanavanich and W. Suntornsuk (Fungal chitosan production and its characterization) I made a first try.
I got brewery waste from Ehringsdorfer Brauerei, also used bakers yeast to compare the results, and did the steps one by one.

My result was very little of chitosan extracted from the yeast.
Further steps:
Simplify the process and produce more chitosan to make some own foils.
