What’s inside

  1. From use-and-throw to a closed loop: does the returnable bottle pay off in the neighbourhood shop?
  2. in emissions per litre served when the bottle is reused at least 20 times, compared with a single-use one
  3. Question, hypothesis and objectives
  4. The starting problem
  5. The cycle of a returnable bottle
  6. Dearer at first, cheaper in the end
  7. The pilot · one click, one neighbourhood
  8. Result 1 · Lower emissions from the eighth use
  9. Result 2 · Lower cost for the shop
  10. Result 3 · People bring them back
  11. The shop's break-even point
  12. Discussion and limitations
  13. The returnable bottle pays off, for the shop and for the planet, from the eighth use.
  14. International forums · five cities, four continents
  15. Forums I have taken part in
  16. Publications and other merits
  17. Thank you
  18. How I counted it Washing is included in the 31 g of CO₂ per litre (at 12 uses): water, energy and transport to the plant
  19. Are twelve shops enough to generalise?
