The United Nations Environment Programme (UNEP) has recognized expanded polystyrene (EPS) transport packaging as a material that is recyclable at scale. This acknowledgment has been incorporated into its recently revised report on plastic pollution science, prepared in anticipation of the INC-4 negotiations to develop an international legally binding instrument to tackle global plastic pollution.

This distinction is significant as it differentiates EPS transport packaging from other applications of polystyrene foam, emphasizing the necessity to evaluate individual material applications and uses independently. Factors such as recycling process technologies, regulatory considerations, contamination factors, and other influencing elements contribute to the range of end-of-life management options.

UNEP has consistently encouraged observer input, a stance evident in the official documents prepared in advance of INC-4. Consequently, the plastic pollution science report now incorporates over 70 new or updated references. Although these documents serve as reference material, they constitute a crucial foundation for the forthcoming negotiations.

Based on the report it’s evident as cited that “while many polymers may theoretically be recyclable, only a few packaging formats have been proven to be recycled in practice and at scale in specific countries and regions. These products include EPS for transport packaging (e.g., fish boxes or protection of large items).”

Betsy Bowers, spokesperson for the Global EPS Sustainability Alliance (GESA) and Executive Director of the EPS Industry Alliance (EPS-IA), in response to the development, revealed gratification on UNEP’s acknowledgment of the recyclability of EPS transport.

Pointing out that through the recognition it’s apparent how consideration of the scientific approach in addressing plastic pollution is crucial especially when it comes to the development of the binding treaty as emphasized by GESA.

“The inclusion of EPS transport packaging’s recycling capability in the report underscores UNEP’s commitment to comprehensively addressing plastic pollution. This update reflects a dedication to fostering a deeper understanding of the complexities of this issue and a willingness to consider stakeholders’ constructive feedback,” said Bowers.

EPS plays a vital role in numerous industries, including packaging, construction, transportation, manufacturing, and automotive sectors. EPS applications encompass packaging for safe transportation of food, essential medicines, and vaccines, protective gear, refrigeration components, insulation for housing, and automotive parts such as car seats. The global plastics pollution treaty could profoundly impact the availability and use of these everyday products upon which many rely.

The Global EPS Sustainability Alliance advocates for a Global Plastics Agreement that promotes a circular economy for all plastics and eliminates plastic pollution. Notably, GESA supports the responsible use of EPS, backed by research-driven solutions and policies beneficial to the environment and the economy.

According to Chresten Heide-Anderson, Project Manager at EPSbranchen – en del af Plastindustrien, Vice President of the European Manufacturers of EPS (EUMEPS), and spokesperson for GESA, GESA champions pragmatic policies and scientific rigor in addressing plastic pollution.

“As we approach INC-4, we advocate for Extended Producer Responsibility and nuanced evaluation criteria to drive meaningful action. We focus on specific applications rather than polymers, incorporating quantitative thresholds and life cycle analysis data. Let us prioritize data-driven decisions for a sustainable future,” said Chresten.

GESA advocates for the following positions as part of its environmental policy recommendations:

• An ambitious plan to eliminate plastic pollution through an implementable agreement.
• The establishment of a scientific advisory board to guide effective actions addressing potentially problematic plastics.
• Chemical transparency for materials, supported by data from reports on EPS’ chemical composition and emissions demonstrating its safety.
• The formulation of independent national plans of action.
• Flexibility to achieve circularity and opposition to lists of banned or restricted polymers, ingredients, and products.
• Adoption of science-based tools such as life cycle analysis (LCA)
