Casein is a protein that is manufactured and made up of protein molecules and moisture. Casein being a macromolecule means it starts off in protein form and must be converted to a plastic physical form in the strongest way possible unless used for weaker products. “Flat sheets of casein plastic were made by adding in water to the rennet casein powder until the moisture content was around 20%.” (Shayne Lang, Being a part of a group called, Phosphoproteins, it contains “82.5% protein and 11.9% moisture.” (Chem Cent J., U.S National Library of Medicine National Institutes of Health) It is a protein found in various things but primarily cow’s milk and human milk. Casein alone isn’t very strong and can be washed away with water so it’s “beefed up with a small amount of clay and a reactive molecule formaldehyde which links the protein molecules together” as stated by Neha Patni, Neha Tripathi, and Sweta Bosmia of the Chemical Engineering Department, Institute of Technology. This makes it easier to use in harder and tougher products like glue, paint, and fiber. Casein is a very beneficial and green substance that can be used in various ways when put to the right use.Casein is a protein derived from milk and it has been used to produce many things that we use every day. For example, Casein is responsible for the production of millions of small goods and for things like adhesive and binding for paint. (Shayne Lang, “Casein Plastic: History, Chemistry, and Manufacture”) The creation of Casein plastic has been used to its many advantages during its main time of use. According to Shayne Lang, Casein has been additionally used for the manufacture of children’s building blocks. Other uses for Casein like “implementations in the food, drug, and cosmetic industries” according to Chem Cent J. of the U.S National Library of Medicine and National Institutes of Health, are also common uses for the helpful substance. Furthermore, Casein is especially important in the application to single-serving wrappers and dissolvable packets because of its weak and dissolvable material. (Katie Rodger, “Paper, Plastic, or Milk?: Non-Food Uses for Milk Casein”) Casein can be made into a biodegradable “plastic” that has multiple uses and purposes. Finally, the components of Casein are what make it able to become a biodegradable plastic. The “basic unit in the casein plastic is a protein, a naturally occurring polymer” (Shayne Lang, and that polymer is formed into a biodegradable polymer with a “casein sample with maximum yield being blended with plasticizers.” (Neha Patni, Neha Tripathi, and Sweta Bosmia, Chemical Engineering Department, Institute of Technology) This proves with work, the casein we use for everyday products can become biodegradable and better suited for our environment. The polymer that is created “contains minimal amounts of carbon” so it’s biodegradable according to Neha Patni, Neha Tripathi, and Sweta Bosmia of the Chemical Engineering Department, Institute of Technology. The casein being used is a “naturally occurring macromolecule that accounts for 80% of the protein in cow’s milk.” (Neha Patni, Neha Tripathi, and Sweta Bosmia) Natural, meaning that it is safe for the environment and not man-made. There are benefits as well that come from casein being biodegradable. For example, edible casein bio-polymers would overall minimize waste because there would be no need to use carbonized plastic. Overall, casein’s biodegradable status and its wonderful benefits and properties are what make it such an outstanding substance that can be put to vigorous use.
