Can Biodegradable Films & Bags Be Recycled Alongside Traditional Plastics?

In most cases, biodegradable films and bags should not be recycled alongside traditional plastics in standard recycling streams. Here's why:
Different Material Composition: Biodegradable films and bags are typically made from biodegradable polymers or bioplastics, which differ in composition from traditional petroleum-based plastics (e.g., polyethylene, polypropylene). Mixing biodegradable materials with conventional plastics can contaminate recycling streams and compromise the quality of recycled materials.
Compatibility Issues: Biodegradable plastics require specific conditions, such as high temperatures and microbial activity, to degrade efficiently. Recycling processes for traditional plastics may not be compatible with biodegradable materials, leading to processing challenges and potential equipment damage.
Contamination Risk: Introducing biodegradable films and bags into traditional plastic recycling streams can contaminate recycled materials and disrupt recycling processes. Contaminated materials may be rejected by recycling facilities or result in lower-quality recycled products.
Certification and Standards: Biodegradable plastics are designed to degrade under certain conditions, such as composting, rather than recycling. While some biodegradable materials may be certified as compostable according to recognized standards (e.g., ASTM D6400, EN 13432), they are not intended for recycling and should be disposed of accordingly.
End-of-Life Disposal: Proper disposal options for biodegradable films and bags include composting, industrial composting, or disposal in landfills equipped with conditions conducive to biodegradation. Recycling is not typically recommended for biodegradable materials unless specific recycling programs or facilities are available for compostable plastics.
It's essential for consumers and businesses to follow proper disposal guidelines for biodegradable films and bags to minimize environmental impact and ensure they are managed appropriately at end-of-life. This may include participating in composting programs or disposing of biodegradable materials in designated composting facilities where available. Alternatively, if composting facilities are not accessible, biodegradable materials can be disposed of in landfills equipped with conditions conducive to biodegradation, where they can break down naturally over time.
