Conventional polymers represent most of the total polymer production, because of their good mechanical properties, low cost and many different utilization functions. Not only does their decomposition last for decades, it also produces microplastics, which are difficult to remove from the environment and have a very profound negative impact on it. Solution for the aforementioned problem could be biodegradable polymers, that degrade when they are exposed to biotical factors. The main resources for producing biodegradable polymers are divided into three generations, based on the dependence on agriculture. The main goal, associated with producing new biodegradable polymers, is to separate its production from the agriculture, while using as little of the materials beneficial for human and animal consumption as possible. Hence bacterial polymers and third generation feedstock, that are not dependent on agriculture, have the most potential. Besides of the development of biodegradable polymers we need to develop new and improved processes for handling these polymers after they are produced. The fact is, having a polymer which is biodegradable in all climates is effectively impossible, so the focus of research was set on specific conditions. This is why not only research and production are important, but also the education of the general public on the different kinds of biodegradable polymers and standardization and more specific labeling of the conditions for their degradation.
