In January 2025, the Official Journal of the European Union formally published the Packaging and Packaging Waste Regulation (Regulation (EU) 2025/40), the new rules referred to as PPWR, which will be fully implemented from August 2026, replacing the nearly thirty-year-old directive. Among the most closely watched provisions is the gradual restriction on expanded polystyrene in food-contact packaging. According to the regulation, from February 2029, products such as food containers and beverage cups made from EPS and XPS will face restrictions on the EU market. This timeline leaves a critical transition window for industries such as seafood processing and cold chain logistics.

For decades, EPS has been the preferred material for seafood packaging. Its closed-cell foam structure provides exceptional thermal insulation, maintaining stable cold chain temperatures during transit; its outstanding impact resistance ensures product integrity during long-distance transport and port handling; coupled with its lightweight nature and low cost, the balance between performance and economics has yet to be fully replicated by any other material. These characteristics have firmly established EPS fish boxes within the global seafood trade system.

Practical Considerations and Limitations of Alternative Solutions

In response to the impending regulatory changes, some companies have begun exploring alternatives. Coated cardboard with biodegradable coatings, various bioplastics, and reusable packaging systems are gradually entering corporate consideration sets. These materials are undoubtedly attractive from a sustainability perspective, but their practical application still faces multiple obstacles. Spanish seafood processor Pescafácil has acknowledged that switching packaging solutions entails significant logistical adjustments and cost increases, imposing a considerable burden on an industry already facing consumption pressures.

Concurrently, some within the industry are attempting to enhance sustainability without changing the material’s fundamental composition. The CELOOPS® fish box, developed through a collaboration between BASF and Knauf Industries, utilizes raw materials derived from chemical recycling processes to replace fossil-based inputs, maintaining EPS’s original performance while achieving a reduced carbon footprint. Nordic company BEWI, through its Circulum® Balance technology, has introduced an EPS fish box with a 60% lower carbon footprint; its facility in Porvoo, Finland, processes thousands of tons of discarded fish boxes annually, reconverting them into EPS raw material. These cases demonstrate that, given the irreplaceability of the material itself, sustainability goals can still be achieved through recycling and regeneration pathways.

The Core Link in Recycling Procedures: Volume Reduction Technology and Equipment Adaptation

Regardless of how new materials evolve, EPS waste that has already entered the consumption stream still requires standardized, efficient processing procedures. The primary physical challenge facing EPS recycling is its extremely low density—over 95% of an empty fish box’s volume is occupied by air, making direct transportation highly uneconomical. Therefore, any effective recycling process must include a critical volume reduction step.

Addressing the specific characteristics of seafood packaging waste, QINFENG recommends adopting EPS Cold Compactors based on cold compaction technology as the core processing equipment. The basis for this choice lies in the particularities of seafood packaging: waste fish boxes often retain moisture, salt residue, and even trace organic matter. If hot melt processes were employed, residual moisture could interfere with temperature control stability during heating, consequently affecting compression results. Cold compaction equipment, by contrast, relies entirely on mechanical pressure generated by a hydraulic system to perform compression at ambient temperature. Operating without heating, it completely avoids the issue of moisture interference.

The operational sequence of QINFENG’s cold compactor is clear and straightforward: after waste EPS fish boxes are fed into the equipment, the high linear pressure from the hydraulic system thoroughly expels internal air, ultimately compressing the material into dense, uniformly dimensioned blocks. This process achieves a compression ratio of up to 50:1, meaning that mountains of loose foam can be reduced to one-fiftieth of their original volume, dramatically enhancing efficiency in subsequent storage and transportation. Key components of the equipment are manufactured from stainless steel, effectively resisting corrosion from seawater and salt spray environments, making it suitable for operational sites such as ports, docks, and seafood processing facilities that may encounter corrosive media.

A Pragmatic Transition Strategy: Moderate Use and Standardized Recycling

In recent years, EPS seafood packaging has been caught in the crossfire of policy and public opinion. On one hand, its poor degradability in natural environments indeed constitutes an environmental pressure. On the other hand, its functional advantages in safeguarding cold chain food products are difficult to replace at low cost. Faced with this practical dilemma, a more pragmatic approach involves accepting EPS’s irreplaceability in specific scenarios while simultaneously establishing standardized, efficient recycling systems for it.

This is the perspective QINFENG tends to adopt: use EPS packaging appropriately, while ensuring its end-of-life is properly managed through professional recycling equipment. A cold compactor placed within a port or processing facility can, day after day, convert waste into transportable, marketable recycled raw material. The compressed EPS blocks can enter subsequent processing stages as industrial feedstock, ultimately being transformed into picture frames, building insulation boards, or other plastic products, achieving a circular transformation from “packaging” to “resource.”

Conclusion

The implementation of the EU’s PPWR regulation brings clear transitional pressure to the European seafood packaging industry, but also leaves a sufficient timeframe. During this transition period, material innovation and recycling system development will proceed in parallel. New materials are continuously being researched and developed, yet none perfectly replicates the comprehensive performance of EPS. Recycling technologies are constantly being refined, with the core objective always being efficient volume reduction and resource regeneration.

For industry participants, establishing standardized recycling procedures for existing EPS packaging while awaiting the maturation of new materials represents a pragmatic and controllable response strategy. The role played by the EPS Cold Compactor in this process is to transform loose, economically marginal waste into uniformly specified, tradable industrial raw materials. This transformation procedure itself does not rely on technological breakthroughs but on the stable operation of mature processes, providing an executable operational model for the sustainable management of seafood packaging.
