The ISCC PLUS certification achieved in this collaboration represents a significant milestone for SeaHiPot in the management and traceability of ocean-bound plastic (OBP) recycling. The signing of the strategic cooperation memorandum further demonstrates the shared direction of DQS and Ningbo Jianfeng in deepening collaboration in green and low-carbon development, the circular economy, and sustainable supply chain management. This parallel approach of certification and cooperation not only responds to the market's increasing demands for credibility and transparency in recycled materials but also lays the foundation for future cooperation on broader sustainability issues.
Certification Implementation: Enhancing the Credibility of Marine Waste Recycling with International Standards
Marine waste refers to plastic waste abandoned on land within 50 kilometers of the coastline with a high probability of flowing into the ocean. Due to its dispersed sources, complex collection chains, and difficulty in tracing, this field has long faced challenges in international market applications, including authenticity verification, compliance validation, and insufficient supply chain transparency.
ISCC PLUS, as an internationally recognized sustainability certification system, sets stringent requirements for raw material sourcing, supply chain traceability, quality balance management, and environmental compliance. Through this audit and certification, DQS independently verified SeaHiPot's management capabilities in the collection, transportation, treatment, and integration of marine waste into its recycling system. This not only signifies greater credibility of the materials in the international market but also provides effective support for downstream customers to identify the source of recycled materials and enhance their confidence in green procurement.
Collaboration between the two parties: jointly promoting circular economy practices through standards and expertise.
The awarding of this certificate coincided with the strategic cooperation agreement, reflecting the consensus of both parties in jointly building a circular economy and practicing sustainable development. The partner company has deep expertise in the field of marine waste recycling and high-value resource utilization, while DQS, with its global certification and auditing capabilities, provides independent verification, system assurance, and internationally recognized endorsement for related sustainable practices.
Against the backdrop of increasingly stringent requirements from global brand customers and supply chains regarding the authenticity, environmental compliance, and traceability of recycled materials, companies not only need recycling and regeneration capabilities but also need to establish market trust through authoritative third-party certifications. The collaboration between DQS and Ningbo Jianfeng revolves around this trend: a forward-looking cooperation framework that more closely connects standards, verification, and industry practices to support the standardized development of the recycled materials industry chain.
Regarding Ningbo Jianfeng and SeaHiPot
Ningbo Jianfeng New Materials Co., Ltd. focuses on the application of circular economy and recycled materials technology. SeaHiPot, as its marine plastic recycling project brand, focuses on the recycling and resource utilization of marine waste and is committed to promoting the treatment of marine plastic pollution and the high-value development of recycled materials.
