The new national standard for limiting the use of recycled plastics has been fully implemented!

Time：

2025-06-16

GB/T45091-2024 "Requirements for Limiting Substances of Recycled Plastics" was officially released in 2024 and will be fully implemented from June 1, 2025. The standard specifies the types, limits, and determination methods of restricted substances for recycled plastic materials.

GB/T 45091-2024 "Requirements for Limiting Substances of Recycled Plastics" was officially released in 2024 and will be fully implemented from June 1, 2025.

The "Requirements for Limits of Restricted Substances for Recycled Plastic" specifies the types, limits, and determination methods of restricted substances for recycled plastic materials. Classify the restricted substances of recycled plastics into control, declaration, and warning categories, and adopt a hierarchical management model of inspection control, declaration acceptance, and warning guidance.

Scope of application

The standard applies to recycled plastic particles and finished products made from waste plastics through screening, classification, crushing, cleaning, melt extrusion (or modified granulation) and other processes. This document also applies to polyethylene terephthalate (PET) bottle flakes. The restrictions on the use of substances specified in this document only apply to the inherent components of recycled plastics specified in this document, and do not apply to subsequent processing such as processing or modification using recycled plastics.

Not applicable to recycled plastics from hazardous waste such as medical waste, pesticide packaging, and radioactive waste, and not applicable to recycled plastics used as food contact and pharmaceutical packaging materials.

Jiayu Testing Reminder

The standard of "Limit Requirements for Restricted Substances in Recycled Plastics" has been fully implemented, which puts forward higher requirements for restricted substances in recycled plastics!

The limit of harmful substances is a key technical element to ensure the rational use of recycled plastics. Jiayu Testing reminds enterprises to strengthen supply chain management in a timely manner to ensure that products meet relevant requirements.
