Despite the recent dwindling patent publication activities, industrial production volumes of bioplastics are increasing every year. However, conventional plastics production has been growing at a faster pace, and the global market of bioplastics has remained only about 1 percent of all plastics. The obvious leading reason is cost. Bio-based polymers are not that expensive; it is more of fossil fuels' low prices that are making bioplastics struggle. The sinking oil prices since 2014, along with recent rapid developments in shale oil, have apparently exacerbated bioplastics' cost disadvantage, forcing a number of producers out of business. Although cost and pricing information for bioplastics are scarce, some estimated price ranges are shown in Table along with those of some conventional plastics. Note that these price ranges are reported for 2010-2011, during which conventional plastics were expensive owing to surging oil prices. Even then, bioplastics offered hardly any cost advantage over oil-based polymers. Nevertheless, the differences may not be unmanageable, and the disparities in cost may not be as hefty as it appears, considering that conventional plastics enjoy economies of scale. Increasing oil prices, diversification of plastics supplies due to the COVID pandemic, and advancements in production may improve the commercial and financial prospects of bio-based polymers. Public perception has been another challenge faced by bioplastics researchers and developers. While the great benefits of bio-based polymers are generally acknowledged, they have sometimes been subject to criticism, and even ridicule, on the basis that they will not solve the world's plastics waste problem; that their productions use farmland and compete for food sources; that they produce methane greenhouse gas while biodegrading; that they have very limited applications and would not replace the majority of conventional plastics; and so on. Whereas some of these concerns are warranted and may have arisen from misconceptions or confusions, the origins of unfounded criticisms and accusations are more elusive. However, it is certain that oil companies, already facing challenges posed by the rapid development of electric vehicles, would suffer further losses in their profit share in the event of major advancements in bioplastics market. With the belief that the benefits of bio-based polymers far outweigh their disadvantages, we hereby share our opinions on some of the most frequently raised concerns in the following myth/fact discussions.
