Notes
Testing Requirements: Biodegradation (>90% within 6 months), disintegration (>90% fragmentation), ecotoxicity (no harm to plant growth), and heavy metal limits1211.
Regional Variations: Spain and Greece enforce strict recycled content rules (e.g., Spain’s “plastic tax” exemption requires EN 15343 certification)13.
