Biosuperabsorbents from waste proteins

Proteins are the major materials used in the body of animals and microorganisms. We are recommended to eat proteins every day. However, there are many proteins that we don't eat such as dead bodies, hair, or old egg! In a recent work that is now being published at Journal of Macromolecular Science, we have conveted egg proteins to a superabsorbent that one gram can absorb a glass of water. It can be good idea covert our waste proteins into superabsorbents for e.g. diapers, and substitute the current oil-based polyacrylates!

(An acetylated and crosslinked protein that is a backbone of a superabsorbent. Read more about it at "Synthesis and Characterization of Biosuperabsorbent Based on Ovalbumin Protein", Journal of Macromolecular Science, Part A: Pure and Applied Chemistry, 2010, volume 47)
