Compostable Packaging Under the PPWR: Article 9 Explained

Article 9 gives compostable packaging a narrow, deliberate role. A short list of formats must be compostable by 12 February 2028: permeable bags for tea and coffee, the single-serve units used with them, and sticky labels applied to fruit and vegetables - formats so small, so food-soiled or so inseparable from organic waste that the compost stream is their only sensible destination. Member states may extend compostability requirements to further formats where their collection systems support it. Everything else claiming compostability must meet the compostability criteria (the EN 13432 family of requirements, certified), be labelled for the organics stream, and stay out of the recycled-content mandate entirely - compostable plastics are excluded from Article 7's percentages by design.

The family attracts more loose language than any other in the regulation, so this station is strict: what must be compostable, what the certification actually tests, what home-compostable may claim, and where the honest answer is a different material strategy altogether.

The case for a compostable format is never the material's virtue in the abstract; it is the item's biography. A tea bag is discarded wet, full of leaves, into a stream that already goes to composting or digestion - a compostable bag rides its contents home. A fruit sticker peels into the compost caddy or stays on the peel that does. Reverse the biography and the case collapses: a compostable crisp packet in a household without organics collection, or in a plastics recycling bin, is a contaminant with a halo. Article 9's narrow list is the biography test written as law, and this station applies the same test to every voluntary compostable decision it examines.

The mandated list first - the formats, the date, the member-state extension power. Then the certification: EN 13432's four tests and what the marks mean. The home-versus-industrial distinction follows, with the claims discipline it demands, then the coffee-pod question the whole sector asks about. The stream-interaction guides come next (compostables in recycling, recycling in compost), the sticky label's specific implementation, the infrastructure reality by member state, and the honest closing guides: compostable films for produce, the cases where compostable is the wrong answer, sourcing certified materials, and food-service operations.

Three products through the test. A salad-bar dressing pot in certified compostable: discarded sealed with food residue at the office, into a general bin without organics service - biography fails; the recyclable-with-rinse or the service-model answer was better, and the compostable version is marketing. A coffee pod in a market with accepting organics collection: discarded wet with grounds into the food caddy - biography passes; certify it, label it, done. A produce bag in a market where the organics stream is the household default and the bag doubles as the caddy liner (the mature Italian pattern): biography passes so completely that the state made it law. The test takes ninety seconds per product. Skipping it has filled this family's enforcement file.

For the portfolio, the station reduces to four artefacts: the mandate map (Article 9 formats and national extensions, per market, with conversion status); the certificate file (finished-article certificates at real thickness, scope-checked); the acceptance map (which collections take which items, per market, reviewed on municipal change); and the claims register entries for every compostable word in circulation. Hold the four current and the family is managed; let any one lapse and the family's failure modes - an uncertified format at the date, a refused stream, an unprovable claim - re-enter through the gap.

The station's rule, portable to any meeting where the word arises: compostable is an answer to a disposal question, not a material compliment. Ask what the item is discarded with, where that stream goes in the markets it is sold, and what certificate proves it belongs there - in that order, every time. The regulation asks the same three questions in law. Portfolios that internalise them will find Article 9 the smallest and easiest station in this guide; portfolios that start from the compliment will find it the most litigated three grams in their range.
