How PPWR is rewriting the economics of recycling

Based on an article by Lars Enge, executive vice president and head of Tomra Recycling.

Most discussions around the Packaging and Packaging Waste Regulation, PPWR, focus on compliance. The broader effect, however, concerns economics. Across Europe, PPWR is expected to increase demand for recycled content, particularly in high-value plastics applications. At the same time, requirements concerning quality, traceability and recyclability are becoming more demanding. Together, these developments are changing the economics of recycling.

Brand owners need recycled content to meet future requirements, while packaging producers need packaging that can be recycled in practice. Converters require reliable access to quality recyclates. Material recovery facilities, MRFs, face pressure to deliver cleaner material streams, and recyclers are expected to supply genuine alternatives to virgin polymers.

PPWR reinforces all these trends simultaneously. For many operators, this marks an important shift. Sorting is no longer limited to recovering material. It increasingly involves producing raw materials with defined quality specifications and documented performance. As recycled-content requirements take effect, value is moving from volume towards quality, creating opportunities for organizations that invest early in traceability, material performance and process control.

Compliance becomes measurable

Demand for evidence is increasing. In the past, it was often sufficient to state that a material was recyclable or contained recycled content. Customers, regulators and value-chain partners will increasingly expect documented answers about the materials entering a process, contamination levels, feedstock stability, achieved purity, and the ability to monitor quality over time.

For recyclers and MRF operators, the capacity to provide this information is becoming more valuable. Data therefore has a larger role in recycling operations. Tomra reports strong interest in material intelligence solutions that provide deeper insight into waste streams and sorting performance. This moves process assessment from assumptions to facts and from periodic sampling to continuous monitoring.

Real-time data is becoming important for understanding material flows, reducing losses, validating recycled-content claims and demonstrating compliance, including in food-contact applications.

Purity determines market access

Quality has always been relevant to recycling, but under PPWR it becomes more directly connected with market access. A recycler producing material suitable for food-contact applications operates in a different market from one supplying lower-grade material. The same distinction applies to bottle-to-bottle PET recycling, tray-to-tray PET recycling and prospective food-grade polyolefin applications.

Even relatively small improvements in purity can significantly influence the value of the final product. Quality levels required for circular packaging are increasingly achievable at industrial scale, with advanced sorting technology playing a key role. Improved object recognition using deep-learning artificial intelligence, more precise material separation and higher-purity flake production can help operators obtain more value from each tonne processed.

The objective is not only to improve sorting, but to produce material that can repeatedly return to high-value applications. PET remains an important focus, while similar opportunities are emerging for food-grade polyolefins as the market seeks high-quality recycled PP and PE. Quality consequently becomes both an operational objective and a business opportunity, changing sorting from a processing stage into a driver of value creation.

Projects such as Sulayr demonstrate how food-grade tray-to-tray recycling can be achieved at industrial scale with full traceability

Feedstock quality as a strategic asset

Feedstock availability is another significant factor. Recyclers can add processing capacity, but they still require access to suitable material for high-quality plastics recycling. As competition for high-quality feedstock increases, MRFs and waste management operators have a decisive role in determining the quality of material supplied to recyclers. The economics of sorting, recycling and packaging are therefore becoming increasingly interconnected.

This is particularly apparent in flexible packaging. Films account for a significant share of packaging placed on the market, but recycling infrastructure and end-market development still have room to expand. PPWR is expected to raise demand for high-quality recycled film fractions.

Operators capable of effectively recovering and upgrading these fractions may access opportunities in flexible packaging recycling and higher-value circular applications. Organizations that focus on feedstock quality now may be better positioned as these markets develop.

Designing packaging for circularity

PPWR also influences packaging design. Brand owners, packaging producers, recyclers and technology providers are working more closely to validate designs, improve sortability and accelerate the use of high-quality recycled content.

Recyclability is moving from a design objective towards a measurable performance criterion. Under PPWR, packaging must demonstrate not only technical recyclability, but also its ability to be collected, sorted and recycled effectively at scale in real operating systems.

Actual recovery continues to depend on local collection and sorting infrastructure. Nevertheless, robust recyclability and sortability assessments are becoming important for supporting compliance and demonstrating the quality outcomes achievable through advanced mechanical recycling.

Technologies supporting the transition

As PPWR changes the economics of the circular value chain, Tomra identifies growing market demand for several capabilities:

• greater visibility into material streams and plant performance;
• better object recognition and material identification;
• higher-purity flake production for demanding applications;
• improved recovery of flexible packaging fractions;
• recyclability and sortability assessments.

Solutions for large-scale operations are already in use. In PET trays, Cirrec and Sulayr Recycling have demonstrated food-grade, tray-to-tray PET recycling at industrial scale, including purity levels above 99.8%. Developments are also taking place in contact-sensitive recycled PP. Amcor Circular Polymers produces recycled content for demanding food-contact applications, while AB Plasta manufactures high-quality recyclates from post-consumer film at industrial scale.

These operations are supported by technologies including Tomra's Gainnext AI system, Innossort Flake and Autosort Flake flake sorters, and the Autosort Speedair film sorting solution. PolyPerception's Waste Analyzer and Tomra Local Control add material intelligence and automation, providing plants with more detailed information about material streams and enabling continuous sorting optimization based on real-time quality data.

From compliance to material value

According to Tomra, customer discussions are moving from compliance towards economics. The central question is no longer whether demand for recycled content will rise, but which suppliers will be able to provide the quality required by the market.

Organizations investing early in material intelligence, sorting performance and quality control may be better placed to use the opportunities arising from PPWR. The operational focus is shifting from recovering material towards producing secondary raw materials capable of repeatedly re-entering demanding applications. PPWR will therefore affect not only compliance requirements, but also the economics of plastics recycling.
