Ecobrick collection, now at Yeadons, Boston Spa

Ecobricks are a simple, low-tech solution to our plastic waste. Without the need for machines, special skills or money, ecobricks enable us to take personal responsibility for the plastic that we’ve used, by keeping it out of energy consuming recycling systems, out of the environment, and putting it to creative good use. In this case, we are collecting for Meadowfield Primary School, Leeds, who will be using them to make planters and seats in their eco garden area and even a sofa for reception!

An ecobrick is a PET plastic bottle packed solid with clean and dry used plastic.  Your ecobricks need to be packed really full, to create reusable building blocks and sequester plastic.  Thus also keeping plastics out of water sources (where they usually end up) and effectively securing it from degrading into toxins and microplastics

Yeadon’s, Boston Spa will accept ecobricks made from 2litre straight sided transparent PET plastic bottle. The bottle and the packed plastic must be clean and dry to prevent the growth of bacteria. Any used plastic can be cut or ripped into small pieces then packed little by little, alternating between adding the hard and soft plastics then compacting it, layer by layer (perhaps starting with softer plastics to fill the voids at the bottle base). We’d suggest using a wooden stick to manually pack the layers of plastic into the plastic bottle. The bottle should be rotated with each press to ensure the plastic is evenly compacted throughout the bottle. This helps prevent voids and that the packing reaches the requisite firmness needed for building block applications. Do the ‘squeeze test!’ if it makes a noise then you need to keep packing!

Please follow these guidelines when making your ecobrick to ensure we get the most use out of them in our creative displays:

  • Your ecobrick is made using a transparent PET bottle
  • We are specifically wanting to collect 2litre straight sided ecobricks only.
  • Make sure you only use hard and soft plastics that have been cleaned and dried.
  • Ideal weight is: 660g (2l bottles), but don’t stress! fill as much as you can (additional guidance below).
  • Please leave the label on the bottle
  • Please seal tight with the screw lid.
  • To add a bit of vibrancy to your design, add a bottom color of soft plastic inside!
  • If you’ve already made a load of ecobricks, we’ll come and collect them, get in touch below.

Meadowfield School has already collected over 500 ecobricks, but they need almost 1,200 to make their creative ideas a reality! please help;

    Hi! I have 8 completed 500g+ ecobricks in bramley, Leeds looking for a project! Are these of any use to you?

    Are you still collecting Ecobricks for Meadowfields School, please?
    I’m happy to drop them off if you are. I’ve got about 12 but the project I was taking them too have got enough now.

      Yes Steph, Yeadons (Boston Spa) are still collecting ecobricks on behalf of Meadowfields School. Please ensure that you are following the guidelines for weight and volume given in this blogpost.

    Hi there, are you still collecting eco bricks? I have lots from a school recycling event that are all the perfect weight. Would you like them?

      Hi Sara,

      Well done. We are still collecting on behalf of Meadowfield School, but only the 2l straight sided bottles now.

      What size are the ecobricks you have from your school recycling event? and how many have you got?

      If they are the right size, it might be worth getting intouch with Meadowfield School directly to arrange drop off (rather than incur the footprint of bringing them here to then get them back out to the School?)

    We are making eco bricks at our school in Cheshire and I wondered if you might know anyone, or how I might find someone, who would be interested in working with the pupils to create an outdoor structure?
