Find out how waste market prices are determined: commodity volatility, recycled materials, metals, plastics, regulation and circular economy dynamics shaping waste value.

For decades, waste was viewed largely as a problem to be managed, an unavoidable by-product of economic activity that needed to be collected, treated and disposed of at the lowest possible cost. Today, that perception is shifting. Increasingly, waste is being recognised as an economic asset: a secondary resource with a market value that rises and falls according to quality, regulation and global demand.
In many sectors, waste is already being bought and sold in much the same way as primary raw materials. The reality is that not all waste is equal. Its value depends on what it is made of, how well it has been separated, and what the market happens to look like at a given moment.

Paper and cardboard provide a clear illustration of how fluid this value can be. Recovered paper is traded using established price indices that set a price per tonne, often varying significantly from one month to the next. When demand from paper mills is weak, perhaps due to reduced consumption or excess stock, prices can fall to the point where they barely cover the costs of collection, transport and processing. In some periods, waste managers have found themselves technically “selling” paper, yet still losing money because logistics costs outweighed the revenue.
When demand picks up, however, the situation can reverse quickly. A strengthening market can turn that same material into a sought-after commodity, especially when high-quality, well-sorted grades are available. For producers, this volatility underlines that waste value is conditional.
Metals, by contrast, sit at the more robust end of the waste-value spectrum. Copper, aluminium and steel are traded globally on commodity exchanges, and their prices are directly linked to international supply and demand. As a result, metal-rich waste streams can represent a genuine source of income for companies, provided they are properly segregated and uncontaminated.
Copper is perhaps the most striking example. Widely used in construction, electronics and renewable energy infrastructure, it is one of the most actively traded metals in the world, and one of the most volatile. In recent years, copper prices have fluctuated roughly between €7,000 and €10,000 per metric tonne. For businesses generating copper-bearing waste, these swings can mean the difference between paying for disposal and being paid for recovery.
Plastics demonstrate just how quickly the economics of waste can change, and how tightly they are linked to wider energy markets. A few years ago, recycled plastics could command prices of €100 to €200 per tonne, depending on polymer type and quality. Today, many producers are once again paying to have plastic waste removed.
The reason lies largely in oil prices. When oil is cheap, virgin plastic becomes cheaper to produce, eroding the competitiveness of recycled material. This makes recycling less attractive from a purely economic perspective, even if it remains desirable from an environmental one. Add to that rising energy costs, stricter quality requirements and the loss of export markets in parts of Asia, and the pressure on plastic recycling economics becomes clear.

All of this highlights that waste markets are shaped by global commodity prices, regulatory frameworks, technological capacity and consumer demand. Policy also plays a decisive role. Extended producer responsibility schemes, landfill taxes and recycled-content mandates can significantly alter the balance, sometimes making materials economically viable that would otherwise struggle to compete.
At the same time, quality is becoming increasingly important. As regulators and end users demand cleaner, more consistent secondary materials, poorly sorted or contaminated waste loses value rapidly. Investment in separation, traceability and process control is therefore a commercial measure.
Looking ahead, the concept of waste as an economic asset is likely to become more prominent rather than less. The push towards a circular economy, combined with concerns about resource security and price volatility, is forcing industries to rethink their relationship with waste. What was once a cost to be minimised is increasingly a resource to be managed strategically.
That does not mean waste will ever be a guaranteed source of revenue. Markets will continue to fluctuate, sometimes sharply. But for companies that understand these dynamics, and invest accordingly, waste is part of the wider materials economy, with all the opportunities and risks that entails.
