One of the largest challenges in polymer chemistry is controlling the tacticity or the stereochemistry of the polymer. When multiplying monomer subunits into the macromolecular chain, it's difficult for scientists to replicate a consistent arrangement of side-chain functional groups stemming off the main polymer chain. These side-chain functional groups greatly affect a polymer's physical and chemical properties, such as melting temperature or glass-transition temperature, and regular stereochemistry leads to better properties. O-carboxyanhydrides are made out of amino acids, which are natural organic compounds, so these polyesters would degrade, unlike the current nondegradable polyolefins. In addition, O-carboxyanhydrides can bring different functional groups to the polyester and diversify the polymer's application. Currently, the FDA has only approved a few polyesters for biomedical application.

 Using bacteria to replace plastics derived from fossil oil  This is achieved by bacteria called Ralstonia eutropha or Cupriavidus necator, also known as oxyhydrogen bacteria. We let them sweat away for us,” Riedel jokes. “We place them in a mineral salt solution and feed them with nitrogen, phosphorous, oxygen and carbon. The carbon is added in the form of waste fats. Then we let the bacteria grow. After a certain time, we remove the nitrogen from the bacteria. They react to this deficiency by storing the now excess carbon in the waste fat as an energy reserve in their cells and converting it into PHAs. If after a certain time we were to start adding nitrogen again, the bacteria would start using the PHAs stored within the cells as a source of energy. Of course, we don’t do this because our aim is to harvest the PHAs produced in the cells. This we do by extracting them using solvents which we can partly recover once the process is complete,” explains Riedel.

Bioplastics and Biopolymers It’s not easy to answer the question of What are Bioplastics? The definition of “bioplastics” is not definitive or universal because not everyone agrees on the definition. here are two attributes related to the word bioplastics. We could say that bioplastics could be divided into two pillars: bio-based and bio-sourced or biodegradable and compostable The Oxford Dictionary defines “bioplastics” as a type of biodegradable plastic derived from biological substances rather than petroleum. This is what we call “bio-based”. The “bio” refers to biological.
