“The TÜV Rheinland team is highly responsible and detail-oriented. They not only provided us with clear and efficient solutions, but also helped us gain a deeper understanding of the verification process and follow-up work. This has enabled us to better promote recycled products that meet post-consumer recycled (PCR)  requirements to customers in Europe and Japan, and successfully expand into new markets.”
— Annie Tse, Director, Luen Kee Plastics

Background: The Rising Demand for Recycled Materials

As the global circular economy accelerates, international buyers are placing increasing emphasis on recycled materials. However, a key challenge for suppliers remains: how to objectively and transparently demonstrate to overseas customers that recycled materials are genuinely incorporated into their products.

Luen Kee Plastic Factory Limited (hereinafter referred to as Luen Kee Plastics) partnered with TÜV Rheinland to enhance product transparency through Recycled Material Verification (RMV), successfully meeting the stringent requirements of markets such as Europe and Japan.

The “Green Challenge” Facing Enterprises

Amid global decarbonization and circular economy initiatives, governments and international buyers are actively promoting the use of recycled materials across supply chains.

However, the recycled plastics industry faces a shared challenge when entering international markets—especially in Europe and Japan—where traceability and compliance requirements for post-consumer recycled (PCR) plastics are becoming increasingly strict.

At the core of this issue lies a technical limitation:
products containing recycled materials cannot be reliably verified through conventional testing methods alone. This creates a “trust gap” across the supply chain, making it difficult to confirm whether recycled content is used as claimed and in the stated proportions.

The Solution: Independent and Objective Recycled Material Verification (RMV)

To address complex market access requirements and customer concerns, Luen Kee Plastics collaborated with TÜV Rheinland, leveraging its extensive expertise in sustainability to implement Recycled Material Verification (RMV) services.

As an independent third party, TÜV Rheinland conducted a comprehensive technical assessment based on international standards such as ISO 14021 and EN 15343.

• The expert team examined the supply chain at its source, verifying the recycling pathways of EPS foam waste and supplier qualifications
• Scientifically calculated the proportion of recycled material in products
• Evaluated the effectiveness of the company’s internal recycled material management system

Through this systematic verification process, Luen Kee Plastics established a transparent data framework that can withstand scrutiny in international markets.

Impact: Enhanced Transparency, Expanded Global Opportunities

With TÜV Rheinland’s independent verification results:

• Communication barriers with target markets were significantly reduced
• Green trade requirements were successfully met
• Downstream customers gained a clearer understanding of compliance pathways

More importantly, transparent data and TÜV Rheinland’s solution improved information flow across the value chain. This enabled Luen Kee Plastics to clearly and objectively demonstrate its commitment to the circular economy, strengthening trust among international buyers and enhancing its competitiveness in global markets.
