Most of us are not very familiar with the types of materials used in biodegradable bags. Below, we will analyze and explain the biodegradable material BDP, hoping to resolve some people's doubts.
BDP refers to materials that can be decomposed and utilized by enzymes or microorganisms (such as bacteria, molds, and algae) and their secretions, including polymer compounds and their composites. BDP involves molecular-level research on the chemical structure of polymers. Its research is of great significance both for the practical protection of the earth, the development of inexhaustible renewable resources, and the academic research on synthetic polymers. However, the research on biodegradable plastics encountered difficulties from the very beginning.
There are three main synthesis methods for BDP: microbial production, chemical synthesis (blending method), and natural polymer modification. Although all types of BDP have good biodegradability, in recent years, based on raw material sources and the concept of sustainable development, they have been divided into two categories: bio-based polymers and biodegradable polymers.
Bio-based polymers are made from renewable resources (such as starch, straw, etc.), carbon dioxide, and biopolymers (nucleic acids, polysaccharides, polyesters, polyisoprene, polyphenols and their derivatives, mixtures, and composites, etc.). The starting point for the development of bio-based polymers is the limited petroleum resources currently widely used, while renewable resources and carbon dioxide are abundant and low-cost, which can meet the requirements of sustainable development. That is, their design is mainly based on the availability of renewable resources, with sustainable development as the goal.
Biodegradable polymers refer to a class of polymers that can be decomposed by microorganisms into carbon dioxide, water, mineralized salts of their elements, and new biomass under certain environmental conditions. As polymers are gradually digested by microorganisms as a nutrient source, leading to mass loss and decreased mechanical properties, the main starting point for their research and development is to address the environmental pollution caused by plastic waste that is difficult to recycle.
