Review of biopolymers (polysaccharides, proteins, microbial polyesters) as petroleum-plastic alternatives
The improper handling of plastic waste has generated an environmental issue due to the high durability of these materials over time, leading to the accumulation of large volumes of waste. The global production of polymeric products, which have a negative environmental impact, has driven the search for alternatives and innovations in substitute materials that promote degradation over time while maintaining the polymeric structure and functionality of conventional materials. Consequently, the development of degradable biopolymers and bioplastics to replace synthetic materials derived from hydrocarbons has begun. This work addresses advancements in the production and application of biopolymers as alternatives to reduce the use of synthetic materials, exploring their conceptualization and various discussions surrounding biopolymers. These biologically derived macromolecules are noted for their ability to biodegrade under natural conditions, making them less harmful to the environment. The study also analyzes the main types of biopolymers, such as polysaccharides, proteins, and polyesters produced by microorganisms, as well as their applications across different industries. Additionally, it explores the current state and perspectives on the manufacturing and application of biopolymers at both national and international levels, emphasizing the importance of adopting technologies that drive progress toward a circular economy. Through this research, the diversity of biopolymers has been conceptualized and classified, promoting the use of natural biological resources and the discovery of new raw material sources for the production of industrial products that support circularity.

Advances in Biodegradable Polymers: Synthesis, Properties and Environmental Applications
AI summary Read the abstract
This review pulls together current research on biodegradable plastics made from natural, synthetic, and microbial sources, looking at how they break down and where they could replace conventional petroleum-based plastics in things like food packaging and farming. Since plastic pollution and microplastics are increasingly linked to health concerns, developing materials that break down safely instead of persisting in the environment (and potentially our food and water) matters for reducing our long-term exposure. The paper notes these alternatives still need more research and better regulations before they can be widely used to replace everyday plastics.
