OK Recycled certification scheme
OK Recycled Certification
The OK Recycled certification scheme defines clear rules for calculating the recycled content of products. It uses a mass balance approach combined with coordinated traceability to verify recycled material throughout the production process. The system follows the requirements of EN 15343:2007 and ISO 14021:2016, ensuring reliable and transparent recycled content claims.
By certifying recycled content, OK Recycled helps companies prove compliance and communicate sustainability responsibly. The scheme supports accurate labeling and prevents misleading environmental claims.
Objectives of OK Recycled
OK Recycled certification supports the goals of Directive (EU) 2019/904, which aims to reduce the environmental impact of plastic products. For example, the directive requires PET bottles to contain at least 25% recycled plastic by 2025 and 30% recycled content in all plastic bottles by 2030.
Therefore, the certification system promotes sustainability by encouraging responsible material use. At the same time, it strengthens trust by giving credibility to company sustainability commitments.
Who Can Apply for OK Recycled Certification
The TÜV AUSTRIA OK Recycled certification system applies to companies that use recycled material in their products. It relies on mass balance calculations and controlled traceability of recycled content across the supply chain.
The certification suits a wide range of materials, including:
- Plastics
- Aluminum
- Fibers
- Paper
Typical applications include packaging, aluminum foils, printing paper, dyes, and other recycled‑content products.
Material Scope and Plastic‑Specific Requirements
OK Recycled certification covers all types of plastics, such as PET, HDPE, PVC, LDPE, PP, and PS. The system tracks recycled content through each stage of the supply chain until the final product reaches the consumer.
In addition, material‑specific requirements may apply depending on the type of material processed. These additional criteria ensure accurate recycled content verification and consistent certification results.
Calculation of Recycled Content
The recycled content of a product is based on a self‑declaration supported by reliable documentation. This documentation includes certificates from relevant suppliers and traceability records.
According to ISO 14021:2016, the recycled content is calculated using a clear and transparent formula:
Recycled content (%) =
(Mass of recycled plastic material × 100) / Total mass of plastic in the product
Therefore, the calculation focuses only on the plastic content of the product. This approach ensures consistency and comparability across certified products.
Benefits of OK Recycled Certification
The OK Recycled certification system ensures that recycled content information is reliable, objective, and easy to identify. As a result, companies can communicate recycled content claims with confidence.
Moreover, the OK Recycled certification scheme and logo help organizations to:
- Consider and meet the requirements of Directive (EU) 2019/904
- Comply with global environmental labelling rules under ISO 14021:2016
- Gain a competitive advantage through independent third‑party certification
- Strengthen their position as an environmentally responsible organization
- Enhance brand value and build trust with customers and stakeholders
- Respond to increasing consumer demand for transparency
- Actively contribute to the transition toward a more sustainable society
