Frequently Asked Questions (FAQ)

What material is 100% biodegradable?

Natural fibers like paper and bamboo are 100% biodegradable. Among industrial polymers, PHA (Polyhydroxyalkanoates) is the most versatile, as it degrades in soil, compost, and marine environments. PLA and Starch-based blends are also 100% biodegradable but are typically engineered for controlled decomposition in industrial or home composting facilities to ensure shelf-stability.

Is bamboo truly biodegradable?

Yes, pure bamboo fiber biodegrades in soil within months. However, many bamboo-based packaging products use synthetic binders or coatings that can leave residues. As a distributor, we recommend Bio-polymer resins (PHA/PLA) for high-volume manufacturing; they offer bamboo’s renewable benefits with superior consistency on standard plastic processing machinery.

How long does it take for PLA to decompose?

In industrial composting (55 — 60℃), PLA decomposes within 90 to 180 days.

  • Shelf-Life: It will NOT degrade during storage. In a standard dry warehouse, our PLA resins remain mechanically stable for up to 24 months. Decomposition only triggers under the specific heat and microbial activity of a composting environment.

What makes a material truly “eco-friendly”?

It must meet two criteria: Renewable Sourcing (reducing CO₂ emissions by up to 80%) and Certified End-of-Life. A truly eco-friendly material must be verified by third-party standards such as EN 13432 or ASTM D6400, ensuring it returns to nature as water and biomass without releasing toxic substances or microplastics.

How long does it take for plastic to biodegrade?

Traditional plastics (PE, PP, PET) never truly biodegrade; they only fragment into microplastics over 500+ years. In contrast, certified biodegradable alternatives like PHA and Starch-blends are metabolized by microorganisms in months, effectively eliminating long-term environmental liability and microplastic pollution.

What is the most biodegradable material?

Paper and hemp are the fastest (2–6 weeks). However, for functional packaging, PHA is the most advanced option because it biodegrades in the widest range of conditions, including marine water and home soil. For cost-sensitive flexible applications, Starch-based bioplastics offer the most efficient home-composting profile.
