War Shows Manufacturers the True Value of Recycled Polymers

When wars disrupt energy and oil markets, industrial chemicals usually feel the shock within days. The latest Middle East conflict is no exception, as shipping disruption in the Persian Gulf, rising crude oil prices, and tightening chemical supply chains are already pushing up the cost of virgin petrochemical feedstocks.

However, some chemical suppliers are emerging as unexpected beneficiaries of the war and what the International Energy Agency has called, “The largest supply disruption in the history of oil markets.” Most notable are traders of recycled polymers and waste-derived feedstocks, who suddenly find themselves in a stronger commercial position as buyers search for alternatives to oil-based raw materials.

The immediate issue is logistics, as so much of the world’s petrochemical feedstock moves through the strategically critical Strait of Hormuz.

Naphtha cargoes from Gulf refiners, for example, are a major input for Asian steam crackers, with the chemical industry journal CE&N reporting that, “Asian petrochemical plants rely on the Middle East for 70–80% of their naphtha feedstock, most of which passes through the Strait of Hormuz.” As these flows slow, are blocked, or become more expensive to insure, chemical producers face difficult choices: pay higher prices for imported feedstock, reduce operating rates, or suspend production altogether.

For example, Reuters reports that, “Malaysia's ​Pengerang Refining Co (Prefchem), a joint venture between Petronas and Saudi Aramco, shut its 300,000-barrel-per-day crude unit last week and ​plans to halt more of its derivative units soon due to a lack of crude feedstock.” Adding that, “Another processor, Singapore Refining Co (SRC), ​has cut refinery runs at its 290,000-bpd Jurong Island site in Singapore to around 60%.”

Even relatively small disruptions can cascade across the value chain. Steam crackers are the starting point for countless petrochemical derivatives, from polyethylene to solvents and glycols. When the upstream system tightens, downstream chemical markets usually follow.

For traders, the first signals are already visible in intermediate chemicals, where glycols and polymer feedstocks have begun moving higher as buyers scramble to secure supply. An ICIS price report noting that, “In the week ended 6 March, virgin polyethylene terephthalate (PET) domestic values rose by up to €110/tonne, virgin high-density polyethylene (HDPE) spot values by up to €250/tonne, and virgin polypropylene (PP) by up to €35/tonne, compared with 27 February. Virgin low density polyethylene (LDPE) spot prices have been rising since late 2025 due to production issues but the conflict saw further increases of up to €170/tonne.”

Energy costs represent the second transmission channel. Conflict in the Gulf typically drives crude prices upward, raising the cost of producing petrochemicals almost immediately. Because so many commodity plastics ultimately trace their cost structure back to crude oil or natural gas liquids, polymer prices rarely remain stable for long once energy markets start moving.

That dynamic is already affecting plastics markets, as early price increases in polypropylene and related intermediates suggest converters are beginning to pass higher costs through the supply chain.

This is where alternatives start to look attractive for chemical industry procurement teams. When virgin polymers rise quickly, the economics of recycled materials improve almost automatically. As the ICIS report adds, “While there has been no direct impact from the Middle East conflict on Europe recycled polymer prices to date, the secondary impacts from price movements in related markets and underlying costs could prove powerful market disruptors.” Specifically noting that, “Throughout 2025 and 2026 to date, substitution pressure from comparatively low virgin PET prices on recycled PET (rPET), and comparatively low virgin and off-spec prices on mixed polyolefin bales, and grades of recycled HDPE (rHDPE) and LDPE (rLDPE), and recycled PP (rPP), that predominantly serve non-packaging applications, has been high.”

The effects of the conflict are also extending beyond polymer chains, with many industrial raw materials experiencing tighter supply conditions because they are closely tied to refining or petrochemical processing. Sulphur, fertiliser inputs, and other refinery by-products are already entering volatile markets because their supply depends on steady oil production and uninterrupted shipping flows.

For manufacturers, this reinforces a longstanding lesson: petrochemical feedstocks are deeply connected to geopolitics. As a result, many companies are reconsidering how diversified their raw material sourcing really is.

For much of the past decade, recycled plastics struggled with the basic economic fact that virgin polymers were often cheaper. This meant that when crude prices were low, many converters used recycled materials primarily to meet sustainability commitments or regulatory requirements rather than purely commercial reasons. However, the current geopolitical environment has changed that equation almost overnight.

As virgin resin prices rise, recycled polymers become more competitive. Recycling companies that had been squeezed by weak margins are now seeing renewed demand from buyers who previously prioritised virgin material as the lowest-cost option.

Looking beyond the immediate impact of the conflict, recycled feedstocks are also offering something increasingly valuable in uncertain times: independence from oil supply routes.

That distinction matters during supply disruptions. For example, polymer feedstocks derived from plastic waste in Europe are largely insulated from shipping risks in the Gulf. For chemical producers trying to stabilise production during volatile markets, this makes recycled inputs an appealing hedge.

Geopolitical shocks often accelerate trends that were already developing slowly, and in the petrochemical industry, the shift toward circular feedstocks is one such trend.

The Iran conflict highlights just how dependent the plastics sector remains on crude-derived raw materials and access to suppliers in the Middle East. It also questions how long manufacturers and consumers will accept that local industries remain so closely tied to political developments in a distant region.

Recycled polymers may not replace petrochemicals anytime soon, but the current crisis is showing how strategically important recycled feedstocks are becoming. For chemical traders and producers alike, they are no longer just a sustainability story; they are increasingly part of the plastics industry’s risk-management toolkit — a credible Plan B for when global supply chains come under pressure.
