INEOS, Petrochemicals, Synthetic Fabrics, Pollution, and Public Money: A Structural Analysis

INEOS occupies a pivotal position in the global petrochemical economy, shaping the production of plastics and synthetic fibres that dominate modern fashion and consumer goods. Although the company is not a textile manufacturer, its influence is embedded in the molecular foundations of polyester, acrylic, elastane, and other fossil‑fuel‑derived materials. This upstream role places INEOS at the centre of both the environmental impacts of petrochemical production and the political economy of state support for heavy industry.

At the core of INEOS’s connection to synthetic fabrics is its production of key monomers and intermediates. Acrylonitrile, one of its flagship chemicals, is the essential precursor for acrylic fibres, which are widely used in knitwear, fleece, carpets, and upholstery. The company also produces ethylene and propylene, foundational molecules for polyester and elastane, as well as solvents and additives used in dyeing and finishing processes. These chemicals form the backbone of the synthetic textile industry, linking INEOS directly to the proliferation of fossil‑fuel‑based fabrics and the microplastic pollution they generate.

The environmental consequences of this petrochemical footprint are significant. INEOS facilities have been associated with elevated emissions of hazardous pollutants, including benzene and ethylene oxide, in communities such as Grangemouth in Scotland and industrial regions in North America. Residents near the Grangemouth complex have repeatedly raised concerns about flaring, smoke plumes, and air‑quality degradation, reflecting a long‑standing tension between industrial operations and community health. These concerns are amplified by the company’s expansion plans, most notably Project One in Antwerp, which has become one of Europe’s most controversial petrochemical developments. Environmental organisations have challenged the project on the grounds that it relies on fracked gas and would generate substantial climate and health impacts, with some analyses suggesting that pollution from the plant could cause more deaths than the number of permanent jobs created. The project has been described as Europe’s largest planned petrochemical facility in three decades, prompting legal action and public scrutiny over its potential to lock in decades of plastic production and fossil‑fuel dependency (ChemAnalyst 2024).

The environmental critique of INEOS is inseparable from its economic and political entanglements. Over the past decade, the company has received substantial financial support from the UK government, often justified as necessary to preserve strategic industrial capacity. Chemical firms owned by INEOS founder Jim Ratcliffe received up to £70 million in UK state aid in the four years leading up to 2025, even before a further £50 million bailout was prepared for the Grangemouth plant (The Guardian 2025). This pattern of support intensified as the government sought to stabilise the site, culminating in a £150 million investment package that included a £75 million government loan guarantee and a £50 million grant to secure the future of the Grangemouth complex (INEOS 2025). A separate government announcement confirmed more than £120 million in public support as part of a joint investment to protect 500 jobs and maintain the site’s role in the UK’s critical national infrastructure (GOV.UK 2025). Beyond domestic operations, the UK government also committed a €700 million financial guarantee to support Project One, signalling political backing for INEOS’s expansion into large‑scale plastics production despite mounting environmental concerns (ChemAnalyst 2024).

These interventions reveal a structural dynamic in which public money underwrites private petrochemical expansion. Governments frame such support as essential for safeguarding jobs, maintaining industrial capacity, and ensuring national resilience in sectors such as defence, life sciences, and advanced manufacturing. Yet critics argue that these subsidies entrench fossil‑fuel dependency, delay transitions to sustainable materials, and expose communities to ongoing pollution. The contradiction is particularly stark in the context of synthetic fabrics: while fashion brands increasingly market recycled or “eco‑friendly” polyester, the upstream reality is that petrochemical giants like INEOS continue to receive state support to expand the very infrastructure that produces virgin plastic feedstocks.

The convergence of petrochemical production, environmental harm, and public subsidy raises broader questions about accountability and the future of material systems. INEOS’s operations illustrate how synthetic fabrics are not merely a matter of fashion trends but are embedded in a global industrial complex reliant on fossil fuels, fracked gas, and large‑scale chemical processing. The company’s environmental controversies, from air‑quality concerns to climate‑intensive projects, reflect the systemic impacts of this model. Meanwhile, the substantial government funding directed toward INEOS underscores the political choices that sustain petrochemical expansion, even as nations publicly commit to climate targets and circular‑economy principles.

Understanding INEOS’s role in this landscape is essential for any movement seeking to reduce fossil‑fuel dependency in fashion and consumer goods. The company’s influence extends from the molecular level of synthetic fibres to the macro‑level of national industrial strategy. Its environmental footprint, combined with the scale of public financial support it receives, reveals the deep entanglement between petrochemical corporations and state power. This entanglement shapes the availability, affordability, and dominance of synthetic fabrics, reinforcing a system in which plastic‑based textiles remain the default material choice despite their ecological and social costs.

To understand how INEOS “goes into” fashion companies, the key is to trace how its petrochemicals flow through the supply chain and end up inside the garments sold by brands like H&M, ASOS, M&S, Burberry, Patagonia, Lululemon and many others. The connection is not direct—INEOS does not sell fabric to fashion brands—but its chemicals are the molecular foundation of the synthetic fibres those brands rely on. This creates a hidden but extremely powerful relationship between one of the world’s largest petrochemical companies and the global fashion system.

How INEOS enters the fashion system through materials

INEOS produces the monomers and polymers that become the synthetic fibres dominating modern apparel. Acrylonitrile, ethylene, propylene and other petrochemical intermediates produced by INEOS are transformed by fibre manufacturers into acrylic, polyester, elastane and nylon. These fibres then move through spinning mills, fabric mills, dye houses, garment factories and finally into the collections of major fashion brands.

This means that when a brand increases its use of polyester or acrylic, it indirectly increases demand for INEOS’s petrochemicals. Reports show that major fashion brands are not reducing their reliance on synthetics; instead, they are increasing it. A 2021 investigation found that 59% of sustainability claims by European and UK brands—including H&M, ASOS and M&S—were unsubstantiated or misleading, while these same brands continued to rely heavily on fossil‑fuel‑based fibres.

A 2024 survey of 50 global fashion companies, representing US$1 trillion in market value, found that brands across fast fashion, sportswear, luxury and supermarket labels are using moresynthetic fibres than before, not less. Another 2024 report confirmed that major fashion brands continue to increase their use of polyester despite regulatory pressure to reduce environmental impacts.

This intensifying dependence on synthetics directly strengthens INEOS’s position in the supply chain. Every polyester dress, acrylic jumper, fleece jacket or stretch‑blend legging ultimately begins with petrochemicals from companies like INEOS.

Why fashion brands remain dependent on INEOS’s petrochemicals

Several structural forces keep fashion companies tied to INEOS’s materials.

• Cost      and scalability: Polyester and acrylic are cheap,      abundant and easy to scale, making them ideal for fast‑fashion production      volumes.

• Performance      marketing: Brands promote synthetics as      “technical”, “vegan”, “recycled” or “durable”, even when these claims      obscure their fossil‑fuel origins.

• Regulatory      delay: Reports show that brands use tactics to      delay or weaken regulations that would reduce synthetic fibre use.

• Lack      of transparency: Many brands refuse to disclose how much      synthetic fibre they use, even as they publicly claim sustainability      commitments.

This creates a system where fashion companies appear to be moving toward sustainability while materially deepening their dependence on petrochemical feedstocks.

What this means inside fashion companies

Inside fashion companies, INEOS’s influence shows up in several ways:

• Material      sourcing decisions: Designers and sourcing teams choose      polyester, acrylic and elastane because they are cheap, predictable and      widely available.

• Marketing      narratives: Sustainability teams promote recycled      polyester or “vegan” synthetics, even though these still rely on      petrochemical infrastructure and generate microplastic pollution.

• Supply‑chain      invisibility: Brands rarely acknowledge the      petrochemical origins of their fibres, allowing companies like INEOS to      remain invisible to consumers.

• Volume‑driven      business models: Fast fashion’s need for constant      newness and high turnover aligns perfectly with the low cost and high      availability of synthetic fibres.

In effect, INEOS is woven into the business logic of the fashion industry. The more garments brands produce, the more petrochemicals they require.

The systemic picture: INEOS as the upstream engine of fast fashion

The fashion industry’s addiction to synthetic fibres is not an isolated trend—it is part of a broader petrochemical expansion strategy. INEOS’s chemicals feed into the global textile system, enabling the mass production of low‑cost garments that drive overconsumption. Reports consistently show that fashion brands are increasing their use of synthetics, resisting regulation and relying on fossil‑fuel‑based fibres to maintain profitability.

This creates a loop in which petrochemical companies expand production, fashion brands increase synthetic fibre use, and consumers are encouraged to buy more garments made from fossil fuels. The environmental consequences—microplastic pollution, carbon emissions, chemical exposure and waste—are externalised onto communities and ecosystems.

Fashion’s synthetic‑fibre crisis is therefore inseparable from INEOS’s petrochemical empire.
