In recent years concerns about global climate change, pollution, dwindling stocks of petroleum, and other factors have led materials scientists to reconsider the virtues of bio-based materials. Compostable biodegradable biopolymers are produced from biomass which comes from crops such as sugar beet, potatoes, wheat, maize, cellulose and chitin. They are generated from renewable sources and are easily biodegradable because of the oxygen and nitrogen atoms found in their structural backbone. Due to the fact that biopolymers have the potential to cut carbon emissions and reduce CO2 quantities in the atmosphere (this is because the CO2 released when they degrade can be reabsorbed by crops grown to replace them) this makes them close to carbon neutral. Biopolymers can be used in packaging materials such as food containers, trash bags, wrappings, loose-fill foam, film wrapping, laminated paper and etc
