Material Identification Codes and the Green Dot: The Old Symbols' Retirement

Two inherited symbols clutter the modern pack face. The material identification codes - the numbers and abbreviations in the chasing-arrows triangle, from the 1997 Commission Decision - identify the material (PET 1, HDPE 2, and so on) under a voluntary system whose arrows consumers persistently misread as a recycling promise. The Green Dot is a financing mark: it signifies that the producer contributed to a recovery scheme, and it has never certified recyclability, recycled content or anything about the pack itself. The harmonised sorting label supersedes the codes' consumer function - sorting language instead of resin numbers - and the transition is the moment to clear both from the face unless a specific market still requires one.

This guide handles the retirement: what each symbol actually obliges, where national rules still demand marks, and how to remove symbols without confusing the sorters who learned them.

Material codes retain a backstage use - converters, recyclers and quality systems read them - and a frontstage cost: consumers sort by them wrongly (any numbered plastic into the plastics stream, whatever its actual fate) and read the triangle as approval. The harmonised label's pictogram logic replaces the code's consumer role with the stream answer, which is the only question the bin-side user has. During transition, where codes remain on packs (production inertia, non-EU markets sharing artwork), placement discipline matters: codes belong in the moulding or the back panel's technical area, not beside the sorting label competing with it. Two symbols answering the same question differently is worse than either alone.

The Dot is licensed by national scheme organisations as evidence of financing participation; its presence is a commercial obligation in some markets' scheme arrangements, entirely separate from the PPWR's labels. Its folklore - generations of consumers reading it as 'recyclable' - is a claims risk the manufacturer carries: a pack bearing the Dot beside an unrecyclable structure invites the misleading-presentation reading the claims guides warn against, in the markets where enforcement reads symbols strictly. The transition plan should map, per market: where the Dot is contractually required, where it is merely habitual, and where its removal is itself overdue. Habit is not a compliance category; retire accordingly.

The 2028 artwork round will add the harmonised label to crowded faces; the professional response is subtraction with a plan. Inventory every mark per face with its basis (legal requirement, scheme contract, standard, habit). Remove in order: habit first (free, immediate), then codes where national practice allows, then scheme marks as contracts permit - banking the space for the harmonised label and the QR rather than letting new claims colonise it. Communicate removals to the sorting audience where a familiar symbol disappears (the digital layer can carry the 'same pack, clearer label' note for a season). A face subtraction programme is the cheapest design improvement available in the whole transition, and the only one that leaves the pack better than regulation required.

Global artwork complicates the retirement: resin codes are required or customary in several non-EU markets (the US state-level chasing-arrows laws are the well-known tangle), and a single global face cannot simply delete them. The management answer is regionalisation of the label panel - the harmonised EU face distinct from other markets' faces, generated from the same component data - rather than a union face carrying every market's symbols at once. The cost of regionalisation has fallen with digital print and late-stage customisation; the cost of the cluttered union face is paid in sorting errors and claims exposure indefinitely. Choose the falling cost.

The folklore had a function: consumers wanted a quick answer and the codes pretended to give one. The harmonised system succeeds only if its pictograms genuinely become the quick answer - recognised at a glance, trusted because they are uniform, and backed by collections that honour them. Businesses can help the succession: retire the old symbols cleanly rather than letting them linger as visual static around the new label, use the digital layer to explain the change once, well, and then let the new system's consistency teach. Successions fail by half-measures; the shelf of 2029 should not be an archaeology of three labelling eras at once.
