Many regular liquid adhesives currently on the market are not biodegradable, which prompted the question of how a new biodegradable liquid adhesive could be formed using natural ingredients. Chemical-based adhesives such as “Krazy Glue” or “Super Glue” are toxic and can be fatal if ingested. Most liquid adhesives contain petrochemical products, meaning that they have their roots in crude oil. Aside from the crude oil, some of the compounds used are polyvinyl acetate, epoxy, polyurethane, and cyanoacrylate polymers. These substances all have their own additional environmental impact.
Chitin (also known as poly acetylglucosamine) and its derivative chitosan, occurs naturally as the building blocks of the shells in all crustaceans and the exoskeletons of every insect. Since this material is an extremely abundant resource, it proves itself to be the perfect candidate for creating a bio-compound with virtually any other organic material.
The purpose of this project was to create a safe and natural liquid adhesive that could be used to adhere simple items together such as paper, cardboard, and fabric.
The outcome of this project was a usable adhesive that can successfully bind together regular white paper, card stock paper, cardboard, and felt fabric. An adhesive has been created that will reduce the waste produced from commercial glues, is safe on skin, safe to ingest, easy to use, and easy to clean up.
