The natural degradation time of wheat straw USB drives is influenced by multiple factors including material composition, environmental conditions, and product structure. Complete degradation typically takes 1-3 years. The pure wheat straw material used by our USB factory generally achieves full degradation within one year.

Disassembling and separating non-biodegradable components is the most critical first step, requiring the removal of electronic parts such as the USB port’s metal connector and flash memory chips.
These components cannot degrade naturally and also prevent microorganisms from accessing the straw casing. By disassembling and recycling electronic components separately, while using only the straw casing for degradation, the decomposition cycle can be directly shortened by over 50%.

1. Wheat Straw Fiber Material
Primarily made from wheat straw blended with a small amount of eco-friendly adhesive, this material retains the characteristics of plant fibers. It has a natural degradation cycle of 1-3 years and a rustic texture, making it ideal for brands emphasizing an “agricultural sustainability” concept.
2. Bamboo Fiber Material
Crafted by grinding bamboo into fibers and compressing them, it offers higher hardness and durability than wheat straw. Degrades in 2-4 years in natural environments with inherent natural grain patterns, making it suitable for premium eco-friendly gift scenarios.
3. Molded Pulp Material
Made from waste pulp and plant fibers through molding processes. Degrades rapidly (6 months – 2 years) at a lower cost. However, it has poor water resistance and is best paired with waterproof coatings for commemorative USB drives.
