Ecobricks Tips

***Plastic Free Swindon can now be found at***

Here’s a few tips that we hope that you will find useful:

  1. Watch the videos on the ecobricks website.
  2. Only use clean, dry, non-biodegradeable plastic. Any organic material can cause the bottle to explode. No metal / foil, as used in some crisp packets and sweet wrappers. Again, see the ecobricks website for further detail.
  3. Start with smaller bottles, if you have them. They are easier to get right.
  4. Intersperse the lighter plastic with the more rigid plastic to maximise the density.
  5. Start with lighter / easily crushable plastic. Scrunching it up a few times first makes it easier to compact in.
  6. Cut the more rigid plastic up and insert it in small layers.
  7. Weigh your bottle frequently to ensure that you achieve the correct density.
  8. If you are filling a bit at a time, make sure you compact the partly filled bottles again before you start adding more plastic, if the bottles have been left for a while the plastic starts to expand.
