Finland's overall return rate for beverage containers is 99%.

Omissions

• The 99% figure is Palpa's figure for aluminium cans (and, per the Ellen MacArthur Foundation summary, glass bottles); PET bottles return at roughly 92%, so the overall/all-containers return rate is lower (Palpa: 'well over 90%', recycling rate 'over 97%').
• No source found that states 99% as the aggregate return rate for all Finnish beverage containers; the claim generalises a single container-type figure to the whole system.
• Most Palpa data points found are undated press releases/pages, so the exact reference year (2024/2025) of the figures could not be pinned down.
