It is understood, in order to find out plastic which is not only completely recyclable but also biodegradable, researchers from Colorado State University (CSU) will be eyeing the compound extracted from the biomass out of the molecule. US Energy Ministry has this material as one of the most suitable items substituted 12 kinds of petrochemical products.
The research team said that from the point of view on the chemical nature, GBL is the same as commercial bioplastics P4HB, but since the latter is based on the bacterial production, so its cost is higher, process is also more complex. Team hopes their findings could lead to lower costs, simpler process for the industry of recyclable, biodegradable plastic.
While some plastics can be recycled through continuous accumulation and manufacture into useful articles, but most of the plastic waste is throwed into landfill or the ocean. Recently, chemists have found a polymer, allegedly, such polymers can be synthesized as a useful material is then broken down into its original structural form and then be reborn.
Although other plastics like PLA and can degrade under certain circumstances, but they also have some drawbacks. Although recycling can be used as a way to extend the life cycle of the material, but it cannot in no case other harmful substances will be decomposed to the original molecular state.
