The Circular Plastic Illusion: How Big Oil Rebrands Fossil Fuels as Sustainable
European supermarket shelves increasingly feature plastic packaging marketed as sustainable and “circular,” but the reality behind these claims reveals a sophisticated greenwashing operation led by the petrochemical industry, particularly Saudi Aramco’s subsidiary Sabic.
The Core Deception
The industry promotes chemical recycling, primarily through pyrolysis, which converts plastic waste into pyrolysis oil. However, this “recycled” feedstock can comprise at most 5% of total input and must be diluted with 95% virgin naphtha—a petroleum derivative. Despite this overwhelming fossil fuel dependency, the entire process is labeled as plastic recycling. The irony is stark: rather than reducing fossil fuel use, the process actually expands it because virgin feedstock must be continually added.
Accounting Tricks Enable Misleading Claims
Two controversial but legal accounting methods allow brands to present deceptively positive environmental credentials:
Mass-balance bookkeeping attributes recycled input to specific output batches. If 5% pyrolysis oil mixed with 95% naphtha is credited to 5% of production, those specific batches can be certified as “100% recycled”—even though they may contain zero actual recycled material, only fossil feedstock. This allows brands like Heinz and Philadelphia to claim sustainability credentials that don’t reflect physical reality.
Avoided emissions accounting creates phantom carbon savings by subtracting emissions that would have occurred if equivalent waste had been incinerated instead of recycled. This makes the process appear climate-friendly on paper, showing about 2kg less CO₂ per kilogram of plastic. However, Sabic’s own life cycle assessment admits the actual pyrolysis-to-cracking process emits 6-8% more carbon than producing virgin plastic from fossil fuels.
Questionable Oversight and Industry Influence
The recycling certifications come from ISCC, an industry-led platform, raising concerns about conflicts of interest. Sabic’s carbon footprint calculations were reviewed by experts including the co-founder of Plastic Energy—Sabic’s main feedstock supplier. Critics note that companies control the parameters of these assessments to achieve desired results, rendering them little more than advertising tools.
Public records suggest Sabic’s recycled content may represent even less than 5% of feedstock, given that 4 million tonnes of naphtha were fed into European cracking plants compared to just 2,600 tonnes of pyrolysis oil in 2022.
Policy Implications
Under intensive petrochemical lobbying, Europe is set to legalize these practices through lax EU rules taking effect in 2026, with similar UK regulations following in 2027. This timing is critical for oil majors: as fossil fuel demand declines due to renewable energy adoption, plastic production represents their future profit engine.
The consequence is deeply troubling—brands’ mandatory recycled-content targets may be technically met while virgin plastic production actually expands. Former EU Commission expert Helmut Maurer argues that what matters is actual emissions, not hypothetical avoided ones, while NGO representatives emphasize that recycled content should be physically present in final products, not just credited through accounting maneuvers.
This system allows the world’s largest corporate greenhouse gas emitter to rebrand its harmful business as planet-saving while opposing production cuts under the UN plastic treaty, perpetuating both the climate crisis and plastic pollution under the guise of sustainability.
