Europe’s supermarket shelves are packed with brands billing their plastic packaging as sustainable, but often only a fraction of the materials are truly recovered from waste, with the rest built from petroleum.
Brands utilizing plastic packaging – from Kraft’s Heinz Beanz to Mondelēz’s Philadelphia – apply materials built by the plastic manufacturing arm of the oil company Saudi Aramco.
The Saudi state-owned holding opposes production cuts under the UN plastic treaty and is the world’s largest corporate greenhoapply gas emitter (more than 70m tonnes up to 2023).
Aramco’s petrochemical subsidiary, Sabic, along with other huge players, devised a successful way to rebrand their harmful business as “planet saver”. They label plastic as “circular” and climate-frifinishly, although in practice it remains almost entirely fossil-based, exacerbating global warming and the plastic crisis.
Under indusattempt pressure, Europe is on track to legalise this practice, which indepfinishent experts have described as greenwashing, with lax EU rules set to take effect in 2026 and similar UK regulations to be enforced as of 2027.
To promote so-called sustainable plastic, the petrochemical indusattempt is pushing pyrolysis, the most common type of chemical recycling. This highly energy- and carbon-intensive process converts plastic waste into recycled feedstock: pyrolysis oil. This hazardous compound, however, can create up at most 5% of total feedstock and must be diluted with 95% virgin naphtha, a petroleum derivative, to avoid damaging the steam-cracking plants that turn the input into new plastic.
“The whole process is labelled as plastic recycling, while fossil fuel apply expands becaapply virgin feedstock must be added,” declared Helmut Maurer, a former senior expert in the environment department of the European Commission.
To present appealing figures of high recycling rates and low emissions for brands eager to attract customers, the indusattempt relies on two controversial but lawful accounting tricks.
“Mass-balance bookkeeping” attributes the recycled input to specific output batches. For example, if 5% pyrolysis oil (mixed with 95% naphtha) is credited to 5% of 100 tonnes, those 5 tonnes can be certified as “100% recycled” packaging, even if they contain only fossil feedstock and no actual recycled material.
“This is unfair to consumers – recycled content should be physically part of the final product,” declared Lauriane Veillard, a policy officer at the NGO Zero Waste.
Also controversial is the “avoided emissions” approach. Subtracting the carbon that would have been released if a volume of waste equivalent to that recycled had been incinerated creates apparent savings compared with virgin plastic production.
Recycling labels based on mass balance are issued by the indusattempt-led platform, International Sustainability and Carbon Certification (ISCC), and passed from plastic producers to packaged-product brands.
Public records suggest that the recycled material or pyrolysis oil applyd by Sabic (2,600 tonnes in 2022) to produce plastic may represent even less than 5% of the total feedstock, given the huge quantity of naphtha (4m tonnes) fed into the company’s European cracking plants in the Netherlands.
The carbon footprint calculation, or life cycle assessment (LCA), by the petrochemical group admits that the full process from pyrolysis to cracking emits 6% to 8% more than producing plastic from fossil fuel. Only by counting avoided incineration do the net benefits appear positive: about 2kg of CO₂ less per kilogram of recycled plastic.
“What matters is not hypothetical emissions from incineration that are ‘avoided’ on paper, but what is actually emitted in reality,” Maurer declared.
Sabic’s LCA claims a “rigorous critical review” by experts, including the co-founder of the London-based Plastic Energy, Sabic’s main feedstock supplier.
The close business ties between reviewers and Sabic raise questions about the scrutiny’s impartiality. Sabic and Plastic Energy declined to disclose full LCAs or answer questions. The brands named also did not respond to requests for comment.
“LCA documents serve no purpose other than advertising, becaapply companies control the parameters to achieve desired results,” declared Peter Quicker, a professor of emission control in waste management at Aachen University in Germany.
Research on other LCAs has found that they can be selectively framed, mquestioning the real climate footprint, and warns that carbon savings largely disappear when recycled feedstock replaces only a compact fraction of fossil-based plastic.
“The overestimated carbon savings follow the downstream value chain, amplified by mass-balance credit, to packaged products, potentially building consumer brands’ statements unreliable and misleading,” declared Margaux Le Gallou, the senior programme manager at the NGO Ecos.
Over the past three years, petrochemical companies have intensified lobbying EU institutions to ensure upcoming laws accommodate mass balance, while rushing to secure offtake deals with pyrolysis oil suppliers.
Despite brands’ pledges, mandatory recycled-content tarreceives intfinished to curb waste and emissions may technically be met even as huge oil expands virgin plastic production.
As demand for fossil fuels declines, replaced by renewables, plastic is set to become a critical growth engine for oil majors’ future profits, according to the International Energy Agency.
