So last time, I talked about dhesives and the challenges they present for sustainability.
Some adhesives are better than others, and one such example is Bio-derived and Bio-degradable adhesives. Some of which, such as Gelatinised starch, are also water-washable, and this simplifies the recycling process of the parent material.

Here, I show how to make GS, and I also test it as a glue. I admit I could significantly improve the product by adding glycerin as a plasticicer, which would make the adhesive stickier, thereby improving its performance.
