April 2026: New Guidelines for Recycling PS and XPS Rigid Packaging

April 2026 marks a pivotal update in Environmental Protection and Safety with the release of EN 18120-8:2026, setting new benchmarks for the sustainable design and recycling of rigid plastic packaging made from polystyrene (PS) and extruded polystyrene (XPS). This European standard, published by CEN, introduces comprehensive requirements and practical guidelines for manufacturers, recyclers, and compliance managers dedicated to closing the loop on plastic packaging waste.

One major international standard has been released this month, addressing core technical and operational aspects for alignment with modern recycling infrastructures. As organizations face increasing regulatory pressure and consumer demand for eco-friendly solutions, these updates play a critical role in advancing the circular economy for plastics.

Overview

The packaging industry plays a vital role in both product safety and environmental sustainability. As global awareness of plastic pollution intensifies, regulatory bodies and businesses are actively seeking ways to enhance recyclability. The design-for-recycling approach underpins these efforts, calling for harmonized technical specifications that ensure packaging products can be effectively collected, sorted, and recycled at end-of-life.

Standards like EN 18120-8:2026 provide authoritative, up-to-date technical guidance for professionals across the value chain. In this article, you'll learn:

Detailed Standards Coverage

EN 18120-8:2026 – Guideline for the Design for Recycling of PS and XPS Rigid Packaging

Packaging – Design for recycling of plastic packaging – Part 8: Guideline for PS and XPS rigid packaging

EN 18120-8:2026 delivers a comprehensive, state-of-the-art framework for designing rigid packaging predominantly made from polystyrene (PS) and extruded polystyrene (XPS), ensuring compatibility with advanced collection, sorting, and recycling systems. This standard extends its evaluation not only to whole packaging units but also to separate packaging components and constituents, such as closures, labels, sleeves, inks, adhesives, and other additives.

Scope and Application

The standard focuses on rigid packaging items where the main body is composed of PS or XPS resins, including:

Primary packaging units (e.g., yoghurt pots, trays, food containers)
Stand-alone components made of rigid PS/XPS (e.g., inserts, lids)

Other packaging materials used in conjunction should also be assessed for their impact on recycling PS or XPS, including how they interact in the recycling process.

Key Requirements and Specifications

Compatibility with recycling processes: Products must be designed for optimal compatibility with state-of-the-art mechanical recycling, such as depolymerization for household packaging and mechanical processing for industrial packaging.
Design guidance: Includes a color-coded compatibility assessment (green, yellow, red) to indicate full, limited, or no compatibility based on materials and components used.
Evaluation methodology: Incorporates references to EN 18120-1 (Definitions and Principles), EN 18120-3 (Sortability), and EN 18120-14 (Protocols for PS and XPS packaging), ensuring holistic assessment.
Components and additives: All integral and separate components—including inks, labels, adhesives—must be evaluated for their recyclability impact. This extends to substances that might be removed or separated during recycling.
Guidance tables: Detailed tables summarize recommended design features for ensuring recyclable outputs, such as:
- Use of compatible adhesives and easy-remove labels
- Avoidance of components that hinder sorting (e.g., dense pigments/barrier layers unless necessary)
- Consideration for full body sleeves, colorants, and UV-protection measures only as required for product safety and consumer information

Who Needs to Comply

Packaging manufacturers and converters designing or producing rigid PS or XPS packaging
Brand owners adopting sustainable packaging portfolios
Packaging designers and engineers responsible for new product development
Recyclers and material recovery facilities seeking process-compatible inputs
Compliance managers ensuring products meet market and regulatory requirements

Practical Implications for Implementation

Organizations must:

Evaluate all packaging components against the compatibility criteria outlined in EN 18120-8:2026
Update design processes to use compliant inks, barriers, adhesives, and materials
Ensure packaging meets guidelines for easy collection, sorting, and recycling within local infrastructure
Collaborate with supply partners to certify component compliance
Reference this standard when pursuing eco-label certification or customer sustainability goals

Notable Changes from Previous Approaches

This is a new addition to the EN 18120 series, establishing PS and XPS rigid packaging as a dedicated focus. It integrates lessons from prior parts (PET, PE, PP) and adapts guidance to the distinctive recycling streams and processing technologies available for PS and XPS today.

Key highlights:

Establishes unified recyclability evaluation for rigid PS/XPS packaging
Requires consideration of all components, including sleeves, adhesives, inks
Introduces color-coded system for assessing recyclability compatibility

Industry Impact & Compliance

The adoption of EN 18120-8:2026 represents a substantial step towards harmonized design standards in the packaging sector, enabling:

Smoother integration into recycling streams: Packaging designed per the standard can be efficiently collected, sorted, and processed in advanced recycling facilities without contaminating output or increasing operational costs.
Regulatory alignment: As circular economy legislation tightens, using standards like EN 18120-8:2026 provides clear evidence of compliance with environmental protection regulations and extended producer responsibility (EPR) schemes.
Market advantage: Organizations that implement the new guidelines can use recyclability claims to distinguish their products, answering growing consumer demand for sustainable packaging.
Risk mitigation: Non-compliance exposes businesses to regulatory penalties, supply chain disruptions, and reputational damage as environmental oversight intensifies across jurisdictions.

Compliance considerations and timelines:

The standard must be adopted as a national standard by October 2026 across CEN member states
Conflicting standards must be withdrawn to remove ambiguity and enforce harmonized practices
Early adoption is encouraged for organizations seeking competitive, sustainable leadership

Benefits of adopting EN 18120-8:2026:

Streamlines product development for recyclability
Reduces post-consumer waste and landfill burden
Enhances brand reputation and market access
Encourages value chain transparency and traceability

Technical Insights

Common Technical Requirements:

Material compatibility: Main packaging must be predominantly PS or XPS, with non-PS/XPS components evaluated for recycling impact
Component evaluation: All attached items (labels, inks, adhesives, sleeves) must be scored for their functional compatibility with recycling processes; full body sleeves, colorants, and additives must be justified by product safety or legal requirements
Process mapping: The standard provides state-of-the-art mapping for accepted recycling technologies, such as depolymerization or direct mechanical recapture

Implementation Best Practices:

Material selection: Choose PS/XPS grades proven compatible with mechanical recycling
Design for disassembly: Allow for easy removal of non-conforming components (labels, sleeves)
Supplier collaboration: Work closely with material and component suppliers to certify compliance
Testing: Apply the protocols from EN 18120-14 for recyclability evaluation—conduct tests in pilot or production environments to validate sorting and recycling compatibility
Documentation: Keep records of compliance and evaluation processes for audit and certification purposes

Testing and Certification Considerations:

Engage with national and European testing bodies for independent assessment
Use assessment tools outlined in EN 18120-8 and referenced standards for consistent evaluation
Pursue third-party certification and labeling as evidence of best practice adoption

Conclusion / Next Steps

With the publication of EN 18120-8:2026 in April 2026, the packaging and recycling industries have clear, actionable guidelines for designing PS and XPS rigid packaging that meets the demands of modern Environmental Protection and Safety initiatives. Adoption of these standards is key for future-ready organizations seeking regulatory compliance, operational efficiency, and sustainable business credentials.
