The Eco Brick! How to make one.

  1. Choose a bottle. This is really important because you need to get the perfect bottle to build the perfect Ecobrick. The key thing to think about is size. Any size bottle will work as an Ecobrick, but the average size tends to be between 500ml to 1.5l. You should also make sure that you’re using a bottle from a product that you use regularly – you don’t want to end up having to buy a plastic bottle just to make an Ecobrick!
  2. Prepare your plastic. Any plastic that you put in your brick needs to be clean and dry – any dirt can lead to microbiological growth and methane forming inside your brick. If you put dirty plastic inside your Ecobrick it can make the bottle bloat and the cap can even pop off – not to mention it won’t look very nice!
  3. Get a stick. You’ll need a stick to poke the plastic in your bottle down so you can fit as much as possible in! A bamboo or wooden stick will work best, and it should have a rounded tip to make sure it doesn’t pierce the bottle when you are squashing the plastic down.
  4. What not to put in your Ecobrick. Remember – the things you put in your Ecobrick can’t be recycled or won’t break down, so be sure not to include metal, paper, card, food waste or glass.
  5. Weigh your Ecobrick. You need to make sure that your Ecobrick is packed as tightly as possible to make it really strong. Bricks that are too soft can’t be used for building because they might not be robust enough. Plus, the more you fit in your bottle, the less plastic will be getting out into the environment! Obviously the weight of your brick depends on the size of your bottle, but as a rough guide a 500ml bottle should weigh around 175g when its full, and a 1.5l bottle should weigh around 500g.
  6. Be careful not to overfill your brick. Although your brick should be packed full of plastic, it shouldn’t be pushing against the lid because it could end up making the lid come off.
