Bioplastics have multiple advantages over fossil resource-derived plastics. They are generated from renewable sources which also fix CO2 from the atmosphere. If bio-based plastics are prepared using similar amounts of energy to plastics from nonrenewable sources, their fixation of CO2 will decrease greenhouse gas emissions at the same output. In addition, many biobased plastics are biodegradable, providing more flexibility in disposing products made with them. The one disadvantage of bioplastics is the cost and time necessary to develop these new polymers to meet market technical needs in barrier, strength, temperature and other polymer properties already met by established plastics.
