Compostable packaging is a type of biodegradable packaging designed to break down alongside natural waste. It's usually made of plant-based materials, like corn syrup, cellulose, or paper, that decompose without leaving toxins behind.

Plasticizers are a general term for a whole range of chemicals added to materials, typically plastic and rubber, to make them softer and more pliable. They're found in countless everyday items like plastic shower curtains, shrink-wrap, PVC raincoats or flexible tubing and wire insulation for homes. Plasticizers, sometimes called phthalates, are also found in cosmetics, like nail polishes, lotions and shampoos.

Crude oil is a complex mixture of hydrocarbons - molecules made mainly of carbon and hydrogen. Refineries and chemical plants separate and transform these molecules into smaller chemical building blocks known as petrochemicals. Some of the most important petrochemical building blocks include chemicals such as ethylene, propylene and benzene.

Midlife is a sensitive biological window where the body becomes more susceptible to age-related stressors, which may explain why this group responds more strongly to chemical exposure. We suspect that men may be at higher risk because the aging markers we analysed are heavily influenced by lifestyle factors such as smoking, which can compound the damaging effects of these pollutants.

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 made from petroleum. Brands using plastic packaging from Kraft's Heinz Beanz to Mondelez's Philadelphia use materials made 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 greenhouse-gas emitter (over 70m tonnes up to 2023).

More research is needed, however, for government agencies to determine whether the chemical levels found in these products requires greater regulation, the study authors say. The hazardous chemicals we identified each carry their own risks, says Elissia T. Franklin, lead author of the new paper and a research scientist at the nonprofit research organization Silent Spring Institute. Our findings showed that these products can expose [people] to multiple chemicals over time, and through repeated use, these combined exposures add up.

They write, 'through clever processing changes, this material is now stronger, more beautiful, and available in higher volumes at a lower price point.' The design remains the same with the frosted look, and this time, it can carry loads better but still lasts only as long as it's needed. After use, the bags can be placed in home compost or industrial compost systems, where they break down into healthy soil.
