Ecobricks are a fantastic solution for tackling plastic pollution. When plastic is exposed to sun and water, it breaks down into smaller pieces (microplastics) and releases toxins. Microplastics scatter around the globe, reaching even the depths of the ocean. By storing plastic in ecobricks, we are preventing pollution.


What you need:

  • Plastic bottles (including lids)
  • Clean and dry plastic rubbish
  • Scissors
  • A magic wand (a stick that is at least the length of the bottle)
  • Scales
  • Enamel paint, nail polish or permanent markers (for writing on the bottle)


    What to do:

    Step 1: Make sure your plastic materials are clean and dry. Dirty plastic inside an ecobrick will cause bacteria to grow and gas to form inside your brick. This can make your bottles bloat and caps pop off.


    Step 2: Ensure your magic wand can reach the bottom of your bottle. We call it your magic wand as it helps your plastic disappear. Bamboo and wooden sticks work best.


    Step 3: Add a base layer. Choose plastic with a solid colour, then push it down to
    the bottom of your ecobrick using your stick. Fill the first 1-2cm of the bottle with
    the same colour.

    Tip: cellophane bags work great. 


    Step 4: Pack it tight. Cut large pieces of plastic into smaller pieces. Also, mix up soft and hard plastic. Don’t overfill it. There should be 1-2cm between the cap and the plastic inside.


    Step 5: Weigh your bottle. To find a perfect weight for your bottle, multiply its volume in millilitres by 0.33. So, a 600ml bottle has to weigh at least 200g. This ensures the ecobrick is strong enough to build with.


    Step 6: Record your ecobrick. Head over to www.GoBrik.com to register your bottle. Don’t forget to write your name, date, serial number (this will be given to you by the app) and final weight.


    Step 7: Choose a project to support. Find out if there are any local community projects who are looking for ecobrick donations. If you can’t find one, there are hundreds online to get involved in.
