The Yale School of Environment website published an article signed by Jim Robbins, titled: Why Bioplastics Will Not Solve the World's Plastics Problem (Why Bioplastics Will Not Solve the World's Plastics Problem)
.
Part of Coca-Cola's plant-based bottle is bioplastic, touted as an important solution to the world's problem of plastic pollution
.
So why are bioplastics, touted as an important solution to the plastic problem, so far short of expectations?
Single-use plastic packaging is the perfect packaging material - strong, light, versatile, clear, inexpensive, and protects the freshness of the product well, and can withstand the acidity and pressurization of soft drinks
.
PLA is one-tenth the cost of PHA, so it is more widely used in disposable tableware and various packaging
.
While both bioplastics in use today can be broken down by microorganisms and become part of the natural world again within a short period of time, the breakdown is only achieved when the plastic is collected and placed in tightly controlled high-temperature industrial facilities
.
Even a 100% plant-based bottle is not a viable solution
.
Many experts believe that the solution to plastic waste lies not primarily in the development of better bioplastics, but in economic restructuring that greatly increases the amount of plastic recycled
.
A recent study published in the journal Science estimates that around 11 million metric tons of plastic now enter the ocean each year, 3 million more than previously estimated
.
