Economía circular en el sector del packaging: innovaciones y materiales del futuro

Packaging has become one of the main friction points between sustainability, regulation, and business. Regulatory pressure, rising raw material costs, and growing transparency demands are forcing companies to rethink their packaging from a circular perspective.

In this article, we analyse how to apply circular economy principles to packaging in a realistic way, which materials are shaping the future of the sector, and how to connect packaging design with regulatory compliance and reporting under the Corporate Sustainability Reporting Directive (CSRD).

What does circular economy mean when applied to packaging?

Applying the circular economy to packaging means redesigning packaging, materials, and usage models to keep resources in circulation for as long as possible, minimise waste, and reduce dependence on virgin raw materials. It is not just about recycling, but about eliminating waste from the design phase.

In practice, circular packaging translates into measurable technical decisions: selecting materials compatible with real recycling infrastructures, reducing weight, using mono-material solutions, enabling reuse, ensuring effective recyclability, and guaranteeing traceability of secondary materials. Every design decision has direct implications for costs, regulatory compliance, and ESG reporting.

Why is packaging a critical lever for circularity?

Packaging represents one of the most regulated, visible, and measurable waste streams. In Spain, more than 30% of municipal waste consists of packaging, making the sector a priority target for regulation, environmental taxation, and administrative control.

Beyond its environmental impact, packaging is directly linked to extended producer responsibility (EPR), the Product Producers Register (RPP), and indicators required under CSRD. Companies that transform their packaging strategy reduce regulatory risks, optimise medium-term costs, and strengthen their ESG positioning with customers and investors.

What drives innovation in packaging materials?

Innovation in packaging is not driven by a single factor, but by the convergence of several structural forces.

From a regulatory standpoint, Spain’s Law 7/2022 and Royal Decree 1055/2022 impose mandatory targets for recyclability, reduction, and reuse, penalising designs that are not aligned with the circular economy. At the same time, volatility in raw material prices is accelerating the adoption of secondary materials and lighter, less complex designs.

Finally, market pressure is increasingly decisive: distributors, end customers, and investors penalise packaging that fails to meet clear criteria for circularity, traceability, and environmental consistency.

Materials shaping the future of the packaging sector

Innovation in materials is evolving towards simpler, traceable solutions that are compatible with existing systems.

High-quality recycled plastics such as rPET and rHDPE are becoming standard across multiple sectors. The focus is no longer only on the percentage of recycled content, but also on material traceability, food-grade quality, and supply stability.

Mono-material packaging is gaining relevance because it enables effective recycling compared to multi-layer structures that are difficult to separate. This technical simplification has a direct impact on EPR costs and circularity indicators.

As for bioplastics, their contribution is limited and highly context-dependent. They only generate environmental value when compatible with existing recycling or composting systems and properly managed. Otherwise, they introduce complexity and regulatory risk.

Advanced paper and cardboard solutions, together with plastic-free barrier coatings, allow the replacement of certain multi-layer packaging applications, particularly where extreme barrier performance is not required.

‍

Which innovations fail to scale?

Not all packaging innovation is truly circular or viable at scale. Some solutions perform well in pilot environments but fail when brought to market.

Materials without proper waste management infrastructure, compostable packaging without separate collection systems, or solutions with low industrial feasibility create risks of non-compliance and greenwashing. Innovation without scalability does not reduce impact and may even increase a company’s administrative and reputational burden.

‍

How does circular packaging affect the RPP and EPR?

Every packaging design decision has a direct impact on regulatory costs and obligations: packaging weight, material complexity, and actual recyclability influence fees paid to Producer Responsibility Organisations (PROs), reporting obligations in the RPP, and indicators required under CSRD.

Reducing weight, simplifying materials, and improving effective recyclability lowers both financial costs and the administrative effort associated with compliance.

Key indicators to measure circularity in packaging

Packaging circularity must be measured using clear and actionable indicators.

The percentage of recycled material assesses regulatory compliance, while kilograms of packaging per unit of product reflect design efficiency.

Actual recyclability measures real environmental impact beyond theoretical claims, and associated EPR costs help control the financial impact of design decisions. These indicators must be integrated into ESG systems to ensure consistency and auditability.

‍

What is the link between circular packaging and the CSRD?

The European Sustainability Reporting Standards (ESRS) require detailed information on resource use, waste generation, and circular economy strategies. Packaging is one of the most relevant and auditable data sources within sustainability reporting.

Companies that connect packaging design with their regulatory reporting processes gain operational efficiency and credibility. Platforms like Manglai enable the centralisation of packaging, EPR, waste, and circularity data in a single system aligned with CSRD.

Common mistakes in sustainable packaging strategies

One of the most frequent mistakes is prioritising image over technical feasibility by adopting solutions that are poorly aligned with operational reality. It is also common to exclude suppliers from early design phases or to disconnect packaging redesign from ESG reporting.

The absence of clear indicators and internal governance turns circularity into a one-off initiative rather than a structural strategy. The circular economy requires management, data, and consistency — not just material innovation.

Circular packaging as a competitive advantage

The circular economy in the packaging sector has become a strategic axis combining innovation, regulatory compliance, and economic efficiency. Companies that adopt a critical, data-driven, and regulation-aligned approach can transform packaging from an operational risk into a genuine competitive advantage.

FAQs on circular economy in the packaging sector

Is every recyclable package circular?

No. A package is only circular if it is effectively recycled in practice.

Are bioplastics always better?

Not necessarily. Their impact depends on context, infrastructure, and waste management systems.

How should companies prioritise packaging materials?

By applying technical, regulatory, and market criteria — not environmental considerations alone.

Does circularity reduce costs?

Yes, when designed systemically and based on reliable data.
