The Shape of Biopolymers as Beauty and Structure




The Shape of Biopolymers as Beauty and Structure
Shape ....Versatility....Function
The miracle of biopolymers has existed for the last 100 years. Safe and biodegradable with a multiplicity of uses and products biopolymers are made from plant material. Biopolymer is a material which can be processed from sugar, nucleic acids, polypeptides (protein) and with further processing can make a variety of different products including high tech materials. PLA or poly lactic acid is a thermoplastic made from corn starch or sugar cane and is used for a variety of packaging, materials, cups, waste disposal bags, coatings for paper materials as well as made for fibers for clothing. It provides an alternative to polystyrene plastics and polyethylene plastics which while in production release more toxins into the air and environment. One of the goals of sustainable production is production with less toxins and the biodegradability of the product. Biopolymers can be made strength and toughness to have a wide variety of uses and is comparable to traditional thermoplastic. Soypolyols made from soy resin produce thermosets, such as different types of foams, polyurethanes, and flexible foam from which different types of insulations, furniture padding and mattresses are made. Current automobile manufacturers are currently using soy foam in the new cars in production for the coming year. As the production of biopolymers increase the costs of production is lessened and can be considerably less to produce than comparable products. There is no product which can exist with no environmental impact but the pleasant alternative of these natural products is a good point for further development.
