One's trash is another’s treasure: How circularity is reshaping waste management in the EU

For decades, EU waste policy was primarily focused on keeping discarded materials – waste – out of the environment, mainly through landfilling and incineration. That objective still holds. But it is no longer the primary reason the topic sits high on the EU’s policy agenda. Circularity now sits at the intersection of environmental policy and industrial strategy, most recently anchored in the Commission’s Clean Industrial Deal (CID).

The EU has begun to view waste as a potential source of materials. Yet the EU still largely operates in a linear economy in which materials are extracted, transformed into products, used, and ultimately discarded rather than recovered. That model functioned effectively when raw materials were abundant, affordable, and accessible through global supply chains. Those conditions can no longer be taken for granted. The EU imports a large share of raw materials needed for its economy. For most commodities, supply comes from diverse sources. For several critical raw materials (CRMs), however, the picture is different: these are materials essential to the energy transition and digital technologies, and their production is concentrated in only a handful of countries. For some CRMs, Europe's dependence on imports is close to absolute.

Besides securing imports, the EU is looking to recover more materials already present in the economy. Heavy rare earth elements[1] are the extreme case, as the EU imports essentially all of them, primarily from China. At the same time, domestic recycling rates for materials such as lithium and other rare earths remain below one percent. As demand for batteries, electricity grids, wind turbines, and data centers continues to grow, securing access to these materials is becoming increasingly important for European competitiveness. An economy that discards its materials and imports the replacements is exposed to both strategic dependencies and higher costs.

Circularity is the EU’s strategic response to those vulnerabilities. In a circular economy, materials are not thrown away after a single life. They are kept in use, and when a product reaches its end, part of the waste stream becomes a feedstock for new production. Recovering materials therefore becomes an industrial capability as much as an environmental objective. For Europe, circularity does two things at once. It reduces the volume of newly extracted material the economy requires, and it reduces reliance on those concentrated suppliers. The ambition is large, and the gap remains substantial. Roughly 88% of the material entering the EU economy today is newly extracted, virgin material.

[1] These are a group of seventeen metals essential to modern technology, including magnets for wind turbines and electric vehicle motors. There are both light and heavy rare earths; heavy rare earths are far less abundant, and their processing is almost entirely concentrated in China.

Some of Europe’s emissions are difficult to eliminate through electrification or efficiency alone. Materials production accounts for roughly a fifth of global greenhouse gas emissions, much of it arising from the energy required to extract, refine, and process raw materials like metals or CRMs. Reusing materials already in circulation cuts both energy use and emissions at their source.

Recycling becomes particularly important in sectors where decarbonization options remain limited. One example is non-energy use, where energy carriers such as oil and natural gas serve not as fuel but as feedstock for plastics, chemicals, fertilizers, and lubricants. In the EU, non-energy use of raw materials accounts for roughly 8% of final energy consumption. It cannot be electrified because the products are built from molecules. A wind turbine blade, fertilizer, a car tire, and a paracetamol tablet all require carbon and hydrogen atoms as material inputs.

Decarbonizing feedstocks requires decarbonized molecules, and there are four routes to produce them: biomass, fossil energy use combined with carbon capture and storage (CCS), decarbonized hydrogen[2] and hydrogen-derived e-fuels, and recycled molecules recovered from products that have reached the end of their life, for example used plastics broken back down into chemical feedstock. The first three are currently scarce and expensive. Sustainable biomass is limited by land and competing uses, CCS remains at an early stage mostly due to costs, and decarbonized hydrogen remains costly at scale. Unlike other low-carbon feedstock pathways, recycled molecules already exist within Europe's industrial system, embedded in products the continent has already produced. Recovering them primarily requires collection, sorting, and processing infrastructure rather than entirely new production capacity. That is what makes recycling seem like the most attractive of the four routes, though not without challenges of its own.

The benefits of material recovery extend beyond feedstock molecules. Recovery bypasses most of the energy used in primary production. Producing aluminum from recycled feedstock takes roughly 95% less energy than primary production, copper takes around 85% less, and steel about 60% to 70% less. For these materials, recycling goes beyond a materials strategy and becomes an energy strategy: less mining, less smelting, less refining, and correspondingly lower emissions, lower energy costs, and lower exposure to industrial carbon costs.

Recycling also faces several constraints. Energy savings do not automatically make recycled materials cheaper. While recycling avoids much of the energy use and carbon emissions in primary production, collection, sorting, and processing introduce additional costs of their own. Circularity also cannot cover future demand growth on its own. Today’s waste cannot supply tomorrow’s larger material needs, particularly as the energy transition itself drives new demand, from copper for grids to lithium for batteries.

Recycling plays a particularly important role in sectors where alternatives remain limited. For the corner of Europe's energy system that cannot be electrified and for the metals whose primary production is most energy-intensive, recovered material is often the fastest and most readily available near-term pathway to decarbonization. Closing that gap begins with a clear picture of what circularity involves, because circularity is considerably more than just recycling.

Both materials security and decarbonization depend on Europe’s ability to recover and reuse materials on an industrial scale. That capability, however, is only one part of what circularity involves. Circularity and waste management are related but not identical, and the distinction matters. Circularity is the broader economic system aimed at maintaining the value of materials and products for as long as possible, through strategies such as reducing, reusing, repairing, remanufacturing, and – only when necessary – recycling. Waste management provides only one part of the system needed for a circular economy. The operational logic of circularity is captured in what practitioners call the R-hierarchy, a family of strategies for keeping material and its value in the economy.

The order of the strategies listed reflects value retention. Strategies higher in the hierarchy preserve more of the labor, energy, and materials already embedded in the product. Recycling, although essential, is the last option because it preserves only the material itself. It does remain preferable to energy recovery, and certainly to landfill.

A circular economy closes material loops. Products are designed to last longer and, when they reach the end of their life, their materials re-enter production as secondary raw materials rather than leaving the economy as waste. The objective is therefore to minimize the need for virgin material. Figure 1 illustrates the difference between the linear and circular models.

The circular transition is redefining what the waste management sector is for. In addition to collecting and treating waste, the sector is increasingly expected to return materials to production as secondary raw materials.

Circularity and waste management overlap but are not the same thing, and no single statistic captures either cleanly. The best available proxy is the EU's own measure of circular economic activity. According to the European Environment Agency, circular economy sectors – meaning recycling, repair, and reuse – employed around 4.4m people in the EU in 2023, roughly one in every fifty jobs, and accounted for 1.8% of GDP.

Two indicators show how much of that activity translates into circular outcomes: the volume of waste Europe generates, and the share of material use that comes from recycled sources. Both have barely moved.

In 2022, the EU generated 2.23bn tons of waste, or roughly 5 tons per person. This is around the same volume as in 2010. Mineral and construction waste dominate that total. Municipal waste, the stream most people picture, is roughly a tenth of it. That is the quantity problem (see figure 2). Waste generation per person remained broadly unchanged despite economic growth. This is a positive sign, showing that growth did not lead to more waste. But a circular economy requires waste volumes to fall, and that has not happened.

The quality problem is captured by the circular material use rate (CMUR), the EU's headline circularity indicator, which measures the share of material demand that is met using recycled materials. Products that remain in use through repair or reuse are highly circular yet never appear in this indicator.[3] The rate has risen by 1.5 percentage points since 2010, and on the current trend, the EU’s 2030 target of 24%, a doubling goal set under the 2020 Circular Economy Action Plan and confirmed in the CID, looks out of reach (see figure 3).

A circular economy would push these numbers in opposite directions: total waste generation down, as products are reused, used longer, and discarded less often, and the circularity rate up, as more recovered material substitutes for virgin input. So far, progress has remained limited.

[3] The European Court of Auditors highlighted that the EU monitoring framework lacks design-related indicators, which limits its ability to distinguish between a circular economy focused on product value retention and a more traditional linear economy focused on waste.

The persistence of high waste volumes and low circularity rates raises a broader question: why does so much material still leave the economy instead of re-entering it? Answering that question requires looking beyond volumes and toward how the waste management value chain actually works.

The chain has a structured split. The factors that determine whether materials can be recovered sit upstream, in product design, collection, and sorting. Economic value, however, is only realized later, when secondary raw materials find an end market among manufacturers and industrial buyers.

Two concepts are central to the discussion and therefore require definition. Quality refers to how clean, consistent, and well-separated a material stream is, which determines which recovery options remain available downstream. A clean stream of PET plastic, the plastic commonly used in beverage bottles, can become a new beverage bottle; the same PET mixed with food residues and other plastics may only be suitable for lower-value applications, such as plastic strapping or fibers. Value refers to the price recovered materials can command when they are sold into end markets. High-quality secondary raw materials can compete with virgin materials when they meet industrial specifications and are available at a price buyers are willing to pay. Low-quality materials sell at a discount, are downcycled, or fail to find a market altogether.

Each stage constrains what the next can do

The waste management chain can be described as a sequence of collection, sorting, processing, and end-use, but in practice each material stream follows a different route. Glass, paper, metals, plastics, textiles, and organic waste differ in how they are collected, sorted, processed, and sold. Figure 4 shows the main operational routes rather than a single path followed by every material.

Not every waste stream passes through every step. Separately collected recyclable streams can move relatively directly toward processing and material recovery. Mixed residual waste, by contrast, may require sorting and still end up largely in energy recovery because only part of the material can be recovered economically.

Each stage nevertheless constrains what the next can do. Weaknesses introduced upstream, such as contamination or poor separation, limit the quality and value that can be recovered downstream. Where materials cannot be recovered, the waste hierarchy applies: energy recovery follows, and landfill remains the last resort.

Treatment capacity is unevenly distributed across Europe, so waste moves to where capacity and cost allow. Ownership varies across the value chain as well. Collection is frequently municipal or contracted by municipalities, while sorting, processing and energy recovery are concentrated among a smaller number of integrated operators alongside many specialist firms. Different parts of the value chain operate under different revenue models. Collectors and sorters mainly earn service revenues and gate fees linked to the volume of material handled. Recyclers and processors depend on material revenues, while waste-to-energy operators combine revenues from waste treatment with revenues from electricity and heat.

For all the scale of Europe's waste management sector, its contribution to circularity remains modest. Despite extensive infrastructure, relatively little material finds its way back into the economy. Understanding why requires looking beyond recycling capacity alone. According to the European Environment Agency, secondary raw material markets continue to face barriers across the value chain, from product design and collection to recycling and end-market demand. Three structural constraints explain the dynamic of these challenges (see figure 5 below).

• Upstream, product design decisions determine what the chain can recover. Products designed for cost, shelf appeal, or functionality rather than recovery often enter the waste system in forms that make material recovery difficult or uneconomic. Multi-layer packaging, composite materials and certain plastics are familiar examples. In many cases, recovery outcomes are influenced long before a product reaches the waste system. Waste management therefore inherits constraints it did not create. Once products reach end-of-life, the sector can only work with the materials and product characteristics it receives. While recent EU initiatives such as the Ecodesign for Sustainable Products Regulation seek to address these challenges, the stock of products currently in circulation reflects design choices made without recovery in mind.

• At the heart of the chain, the actors that influence material quality are not always the actors that ultimately capture the value created by that quality. The costs of poor material quality are often felt further downstream than where they originate, creating imperfect alignment across the chain.

• Downstream, secondary raw materials compete with virgin materials on cost, consistency, and reliability. End markets exist for many recycled materials, including metals, paper, glass, and plastics. The challenge is ensuring that recycled materials can deliver the quality, consistency, and reliability that end markets require. Manufacturers typically require consistent quality, reliable volumes, and competitive pricing. Recycled materials can struggle to meet these requirements, particularly where waste streams are contaminated or material properties degrade during use and recovery. Without buyers willing to purchase recovered materials at prices that support the economics of recycling, investment in higher-quality recovery doesn’t pay off.

The transition is inherently gradual. Materials remain embedded in buildings, infrastructure, vehicles, and consumer goods for years before becoming available for recovery, while demand for new materials continues to grow. Virgin materials will therefore continue to play an important role even as recycling expands.

The three constraints do not bind equally. Design and quality shape what can be recovered, but neither pays for recovery. Without buyers willing to purchase secondary raw materials at prices that cover the cost of producing them, upgrading design or sorting simply doesn’t pay off. End-market demand is therefore the constraint that determines whether the other two problems are worth solving.

The state of end-market demand also determines who benefits from the waste management value chain. Collectors and many sorting operators profit primarily from service revenues linked to handled volume, making them less directly exposed to end-market prices than processors that depend on material sales. Recyclers sell the material itself, so they carry the market risk, and no amount of operational improvement removes it. Where recyclers reduce that exposure, they do so contractually through offtake agreements, or by integrating forward to the end market.

The barriers discussed in this chapter are structural rather than technological. Addressing them requires changes across the value chain, from product design and manufacturing to collection systems and secondary-material markets. Increasingly, this is also the direction of European circular economy policy.

That is where the response is now concentrated. A second article examines the EU regulatory framework, the Circular Economy Act expected in the third quarter of 2026, and what the shift toward binding obligations means for each part of the value chain.
