Do you know about biodegradable materials

April 22 this year marks the 55th anniversary of Earth Day, with the theme of “Global War Shaping.” It aims to implement the principle of “saving resources and protecting the environment”, adhere to the principle of giving priority to conservation, protection and natural restoration, further strengthen the protection and utilization of natural resources, promote green and low-carbon development, and jointly build a beautiful earth.

Do you know about biodegradable materials

Protecting the environment has become the trend of the new era, and in the face of this environment, biodegradable materials have begun to appear. So what is biodegradable? Let’s take a look at biodegradability.

What are degradable materials?

Degradability refers to the characteristics of substances that undergo biological or physical processes in the natural environment and eventually decompose into harmless substances, and can be fully absorbed or reused by the environment.

Biodegradable substances can be divided into two categories: biodegradable and physically degradable.

Biodegradable: These substances can be broken down into smaller compounds through biological activity, such as the action of microorganisms or enzymes, which can then be completely degraded by microorganisms in nature. For example, some bioplastics are made from degradable polymers that are able to degrade to water, carbon dioxide and biomass through microbial metabolism under suitable conditions.


Physically degradable: These substances are gradually broken down into smaller fragments in the natural environment through physical processes, such as sunlight, oxidation or mechanical wear, and eventually disappear. For example, some plastic bags and packaging materials use physically degradable technologies that allow them to gradually break down into tiny pieces under the influence of natural factors such as sunlight and oxidation.

What are biodegradable materials?

Biodegradable materials, also known as biodegradable plastics, refer to degradation caused by microorganisms existing in nature (such as soil, sand, freshwater environment, seawater environment) or specific conditions (such as compost conditions or anaerobic digestion conditions). And eventually completely degrade into carbon dioxide or/and methane (depending on ambient oxygen levels), water, mineralized inorganic salts of the elements they contain, and new biomass plastics.

According to the classification of raw material ingredients, biodegradable plastics can be divided into two categories: biodegradable biodegradable plastics and petrochemical biodegradable plastics. Bio-based biodegradable plastics include plastics directly processed from natural materials, such as thermoplastic starch; Polymers derived from microbial fermentation and chemical synthesis, such as polylactic acid (PLA); And polymers synthesized directly by microorganisms, such as polyhydroxyalkanoate (PHA). Petrochemical based biodegradable plastics refer to plastics obtained by chemical synthesis of petrochemical monomer polymerization, such as Poly(Butylene Adipate-Co-Terephthalate) (PBAT), Poly (Butylene Succinate) (PBS), carbon dioxide copolymer (PPC), polycaprolactone (PCL) and so on.

With the promotion of the “plastic limit order”, we will find that lunch boxes, straws, etc. have been replaced with new materials, and the matrix material used is PLA; And we usually use shopping bags, garbage bags, express bags, plastic wrap and other film bag products, most of them contain PBAT. At present, the mainstream biodegradable plastic raw materials on the market are mainly thermoplastic starch, PBAT and PLA three categories of biodegradable materials, taking into account the cost performance and comprehensive performance requirements, the biodegradable products on the market usually choose one or two of the above raw materials, and supplemented by processing AIDS and fillers for blending modification.

Why use biodegradable materials?

The use of biodegradable materials is of great significance to environmental protection. Compared with traditional refractory materials, degradable materials can reduce environmental pollution and waste accumulation. When these substances are treated and disposed of correctly, they can be converted to harmless substances as quickly as possible, reducing the impact on soil, water and wildlife.

However, it is important to note that being biodegradable does not mean that it degrades rapidly under all environmental conditions. The rate of degradation depends on factors such as the type of substance, environmental conditions, treatment method, and microorganisms present. Therefore, rational use and proper disposal are still the key to protecting the environment. In practice, biodegradable materials should be selected and promoted as much as possible, while effective recycling and reuse systems should be established to reduce the negative impact of waste on the environment.
