Factual Building Towards a Better Future Ecobricks are reusable plastic building blocks. An ecobrick is a plastic bottle packed with single-use plastics to a set density, used by developing countries to make affordable garden structures and buildings. You can also use ecobricks to make furniture for your own home. It is fairly simple to make your own ecobrick. Here’s how: 1. Start collecting plastic It is very important to only use clean, dry plastic; for example, polystyrene, straws, packaging and plastic bags. Do not use paper, glass or metal. 2. Choose the plastic bottle Ensure that all the bottles you use are the same size and brand because, if you are building a solid structure, your bricks have to fit perfectly. Smaller bottles (600 ml or less) are a good choice to get started with, because you can finish your brick much faster and learn from any mistakes before you move on to bigger bottles. Do not use a bottle with a crack in it. 3. Find the right stick You will use a stick to pack your bottle with as much plastic as possible. Bamboo and wood make the best sticks. Choose a stick that’s roughly twice the height of your bottle and make sure that the tip is rounded; a sharp tip might damage the bottle. 4. Add a bottom colour The first piece of plastic will give your ecobrick a bottom colour, so choose wisely. Pick a few soft pieces in your chosen colour and pack the bottle so that the plastic fits in the corners at the bottom. Continue to pack more soft plastic tightly for up to 2 cm. 5. Organise your plastics Cut the rest of your plastics into smaller pieces. The smaller the pieces, the denser the filling and the better for your ecobrick. Mix soft and hard plastics and use your stick to press the plastic right around, packing it tightly. 6. Weigh your ecobrick A solid ecobrick has to be strong and densely packed. A good weight for a 600 ml bottle is at least 200 g. If your ecobrick is underweight it will be too squishy to build solid structures. Continue to stuff the bottle with plastic to reach the goal weight. Leave 1–2 cm at the top of the bottle and tightly cap it. 7. Store Store your ecobricks until you have enough to complete your project. 48 Reading for Me Level 4 (Part A) 978-1-922843-63-0 R.I.C. Publications ® Prim-Ed Publishing
