The world of airsoft sports has seen an increasing interest in using biodegradable BBs as a more environmentally friendly option for ammunition. As a popular recreational activity, airsoft enthusiasts are becoming more aware of their impact on the environment and are looking to make more sustainable choices. The question of whether airsoft BBs are biodegradable is a pressing topic as players seek to reduce pollution caused by non-biodegradable plastic pellets.

Are Airsoft BBS Biodegradable

Airsoft BBs come in two main varieties: biodegradable and non-biodegradable. Biodegradable BBs are made from polylactic acid plastic, a material which breaks down in the environment more quickly than traditional plastic BBs. When exposed to the elements, biodegradable BBs can break down in as little as 90 days, while non-biodegradable plastic BBs can take years to deteriorate. The longer deterioration period for non-biodegradable BBs has a significant environmental impact, as these pellets can persist and accumulate in outdoor playing fields.

Many airsoft players have embraced biodegradable BBs as an eco-friendly alternative, without sacrificing performance or causing damage to their airsoft guns. As the airsoft community continues to grow and develop, the adoption of biodegradable BBs is a crucial step in reducing the environmental impact of this popular recreational activity.

What Are Airsoft BBs

Airsoft BBs

Airsoft BBs are small spherical projectiles used in airsoft games. They are specifically designed to be fired from airsoft guns and provide a realistic shooting experience without causing significant harm. Airsoft BBs typically measure 6mm in diameter and come in a variety of materials, weights, and qualities.

There are two main types of airsoft BBs: biodegradable and non-biodegradable. Non-biodegradable BBs are made from plastic materials, such as ABS or PVC, which can take several years to degrade in the environment. Their longevity poses a potential environmental threat, especially when used outdoors where they can accumulate and pollute soil and water sources.

Biodegradable airsoft BBs, on the other hand, are made from eco-friendly materials that decompose over time. The most common material used for biodegradable BBs is polylactic acid (PLA), a renewable resource derived from cornstarch or sugar cane. These BBs break down in the environment, typically within 90 days to three years, depending on conditions such as moisture and exposure to sunlight.

Airsoft players can choose BBs of varying weights depending on their preferences and the specific guns they use. Lighter BBs, such as 0.12g or 0.20g, are suitable for low-powered spring guns, while heavier BBs, like 0.25g, 0.28g, or 0.30g, are more appropriate for high-powered electric or gas-operated guns. The weight of the BB will affect its trajectory and accuracy due to factors such as wind resistance and inertia.

In conclusion, airsoft BBs come in different materials and weights to suit various guns and scenarios. The choice between biodegradable and non-biodegradable BBs lies in the concern for the environment and personal preferences. Regardless of the type, it is essential to use appropriate BBs for specific airsoft guns to ensure smooth operation, safety, and an optimal gaming experience.

Biodegradable vs Non-Biodegradable BBs


Biodegradable BBs are usually made from polylactic acid (PLA), a type of plastic derived from lactic acid and starch. This material is commonly used in applications that require biodegradability, such as sutures, due to its ability to break down naturally in the environment.

On the other hand, non-biodegradable BBs are made from traditional petroleum-based plastics. These plastics do not decompose quickly or naturally, resulting in a longer-lasting environmental impact.

Environmental Impact

The environmental impact of biodegradable BBs is significantly less than that of non-biodegradable BBs. Biodegradable BBs decompose over time, reducing the pollution they cause and lowering their contribution to non-organic waste in the ecosystem.

Non-biodegradable BBs, however, take years – even decades – to decompose, leading to increased pollution and environmental damage. Fields that experience frequent airsoft gameplay may become cluttered with plastic BBs that persist in the environment for an extended period.

Degradation Process

The degradation process of biodegradable BBs typically takes around 6 to 8 months in humid or damp conditions, with complete biodegradation occurring in up to three years. These BBs are water-soluble and break down through the action of microorganisms, which consume the organic materials present in the PLA composition.

In contrast, non-biodegradable BBs undergo a considerably slower decomposition process, often taking several years or longer to break down. Unlike biodegradable BBs, they are not easily decomposed by microorganisms and remain in the environment, contributing to pollution and negatively impacting ecosystems.

Factors Influencing BB Degradation



Temperature plays a significant role in the degradation process of biodegradable airsoft BBs. Generally, higher temperatures expedite the breakdown of the BBs. In warmer climates, the biodegradable materials are more likely to decompose at a faster rate compared to colder climates. Temperature fluctuations may also affect the rate at which the BBs degrade.


Humidity is another essential factor that impacts the degradation of biodegradable BBs. High humidity levels can accelerate the decomposition process, as moisture in the air can facilitate the breakdown of the material. On the other hand, low humidity levels may slow down the process, as there is less moisture for the BBs to absorb, making the breakdown less efficient.


Sunlight can influence the rate at which biodegradable BBs degrade, particularly through ultraviolet (UV) radiation. Exposure to sunlight and UV radiation can cause the BBs to break down more quickly, as UV radiation triggers the degradation process in many biodegradable materials. Therefore, BBs left exposed to sunlight in outdoor environments will likely decompose faster than those shielded from sunlight.


Moisture is crucial for the degradation of biodegradable BBs. In the presence of moisture, the BBs can absorb water, which facilitates the breakdown of their materials. Conditions with higher moisture content, such as wet environments, rain, or damp soil, can speed up the decomposition process. In contrast, drier conditions or environments lacking moisture will result in a slower degradation rate.

Soil Conditions

Soil Conditions

Soil conditions greatly influence the degradation rate of biodegradable BBs. Factors such as soil type, pH levels, and microbial activity all contribute to the efficiency of the BBs’ breakdown. For example, soils with a higher microbial activity can expedite the decomposition process, as microbes aid in breaking down the BB materials. In addition, soil contact is vital, as BBs in close contact with soil are more likely to degrade due to increased exposure to moisture and microbes.

Performance and Quality of Biodegradable Airsoft BBs


Biodegradable airsoft BBs are made from polylactic acid (PLA) plastic, which ensures a homogeneous structure and consistency in their design. The manufacturing process focuses on maintaining uniform size and shape, which plays a significant role in providing consistent performance during airsoft gameplay.


Accuracy is an essential factor for airsoft players, and biodegradable BBs strive to deliver a comparable level of accuracy to standard BBs. The uniform size and shape contribute to better accuracy in shooting, allowing players to rely on biodegradable BBs for their outdoor military and tactical training without compromising on performance.


Biodegradable BBs are available in multiple weight options, just like their non-biodegradable counterparts. The choice of weight depends on the player’s preference, intended use, and the specific airsoft gun being used. Common weights include 0.20g, 0.25g, and 0.28g. Heavier BBs tend to be more stable in flight, while lighter ones offer more extended range, allowing the user to choose the most suitable option depending on the desired attributes.


In terms of range, biodegradable BBs perform similarly to regular BBs. The range is mainly influenced by the airsoft gun’s power, design, and chosen BB weight. The consistent size and shape of quality biodegradable BBs help ensure a reliable range during gameplay. However, it is crucial to store the biodegradable BBs properly to prevent exposure to moisture, as it can cause them to deteriorate and negatively impact the range and overall performance.

By taking care of storage conditions and choosing an appropriate BB weight, biodegradable airsoft BB users can expect a confident, knowledgeable, and neutral shooting experience.
