Cara Membuat Ecobrick

Ecobricks can be made by the young, the old and everyone in between — no machines, special skills or experts required! However, there are important guidelines to follow to ensure the quality and usability of your ecobricks.

Be sure to start ecobricking right— this is a long-term life habit that you, your household and community are beginning. Likewise, your ecobricks will set the example for everyone around you. Sub-standard ecobricks will compromise the quality of furniture modules, constructions and the social spread of ecobricks while, well-done ecobricks can be put to good, safe use and will secure plastic for centuries. We’ve put this 10 step guide together to help you on your journey of making great ecobricks.

1. Save, Segregate, Clean & Dry Plastics

Ecobricks are made with clean and dry plastic. Start by segregating your plastic from all other materials.

Save, segragate, clean, dry plastics

Some ecobrickers bring a bottle with them everywhere they go. Others save up their ecobrickable plastic in a bin til they have time to get to it.

If there is any food, oil or dirt on your plastic, be sure to wash it off. Dirty plastic inside an ecobrick will lead to microbiological growth and methane forming inside your ecobrick (for a solution for dirty plastic see the Ocean Ecobrick). Since ecobricks are often used to make home furniture you also want to avoid unsightly ecobricks, bloated bottles and in rare cases, caps popping off.

Its likewise important that the plastic is dry! Wet and moist plastic will also encourage mircobial growth. Ecobrikers around the world use different methods for drying their washed plastic– from laundry machines to cloths lines.

2. Choose your bottle

Before you start ecobricking, choose one specific bottle and stick with it.


Choose the ideal bottle type

When it comes time to building, having perfectly identical ecobrick sizes is important for making solid and steady modules. It also helps having at least the same general size of bottle when it comes to building with earth and ecobricks. Talk with ecobrickers in your community and make the choice together of what bottle to use.

When selecting the bottle that you will use, consider three factors: the bottle’s availability, the volume, and the project you will use the ecobrick for.

  1. Availability

    The last thing you want to have to do is buy drinks to have a bottle for your ecobricking! Soon many people will be ecobricking in your community and it is ideal to have everyone using the same brand and bottle. Be sure to choose a bottle that everyone can easily come by.

  2. Bottle Volume

    Choose the bottle volume you want to go with. GEA Trainers teach ecobricking with bottles under 600ml. Large 1500ml bottles will take a lot of plastic, but also take a long time to make! Small volume bottles allow first-time ecobrickers to finish their first ecobrick and quickly learn from their mistakes. Large bottles are best for advanced ecobrickers.

  3. Your Project

    For building modules with Ecobricks, you need bottles that are exactly the same size and shape. For outdoor building projects, exact sameness is not so important, so long as the volume is consistent (i.e. all 600ml bottles). Depending on the size of construction, you will need different size bottles. For example, small bottles make good walls, and large bottles make good benches.

3. Get your stick ready

Ecobrickers like to call their packing stick, their magic wand. It makes the plastic disappear!


Pack your eco-brick with recycle plastics using a stick

Having the right stick will make a big difference to your ecobricking.

Bamboo and wood make the best sticks. The size of the stick depends on the type of bottle you go with. You want a stick with a diameter roughly one third the width of a standard bottle opening– so about 6mm. You want your stick to be about twice the height of your bottle, with a slightly rounded tip. Avoid sharp cornered sticks as they can rupture your bottle– and yes, this means you have to start your ecobrick all over again!

Once you've got a stick with a good size and shape, you’re set! You can then give it to others to copy and replicate. That’s how our GEA Trainers do their workshops- more magic! One stick turns into many!

4. No glass, metal or biodegradables

What you don't put in your ecobrick is just as important as what you do!

what to put in your eco brick

The reason we are putting plastic inside a bottle is to secure it- otherwise it would get loose into the environment and degrade into microplastics and toxins. Stuff like cotton cloth, metal, paper, cardboard, glass, and organic material will not degrade into toxins so there is no need to secure them. Be especially careful not to pack sharp metal or glass into an ecobrick– they can rupture the sides and pose a danger for handling. There are other solutions for these materials:

  1. Paper and cardboard can be safely industrially recycled, composted, or burnt.

  2. Biodegradables can be composted or left to biodegrade.

  3. Metals and glass can be industrially recycled.

5. Start by adding a bottom color

It is important to start your ecobrick by adding a bottom color.

Add a bottom color to your eco brick

This is part of the circular design principle of ecobricking: we're thinking about the next use of the ecobrick. When your ecobrick is put to use in a module or an earth construction, the bottom color will help make patterns and designs.

To create your ecobrick's bottom color, choose a soft plastic with a solid color, then push it down to the bottom of your ecobrick. You'll want to fill the bottle loosely about halfway with soft plastic of your chosen color. Then, pack it in with your stick. If your bottle has "legs" or dimples at the bottom, be sure to pack these solid and full. Once all your soft plastic is compressed, you want it to fill the first 1-2cms of the bottle.

Often schools or companies will ask their ecobrickers to make ecobricks with their community colors. By giving your ecobrick bottom a color, you open up colorful design possibilities for making modules or earth and ecobrick walls.

6. Pack the bottle tight, mixing plastics as you go

Now it's time to pack away! Cut or rip up large plastics into smaller pieces.

Pack your eco-brick right with recycled plastics

The smaller the pieces, the denser you'll get! Fill the bottle up halfway with loose plastic, then use your stick to push down around the sides of the bottle. Keep pushing down as you move around the circumference of the bottle. Once compressed, add more loose plastics. To maximize the density, it's good to mix soft, then hard plastic. If it's your first ecobrick, weigh occasionally to make sure you are on track for your target minimum weight.

Did you push too hard? In rare cases, when using a sharp stick, a thin bottle or too much lateral force, an ecobrick will rupture. If so, start again. Ruptured bottles will not last and can leak plastics. Cut the bottle open, remove the plastic and start again. Cut or damaged PET plastic is readily recycled.

7. Weigh your Ecobrick to ensure quality

Now it's time to weigh! Cut or rip up large plastics into smaller pieces.

Weigh the eco brick and its recycled plastic waste

Ecobricks that are solid and strong are densely packed. The full volume is used for plastics, and there is no air or spaces inside. The GEA has determined that an ecobrick's density must be higher than 0.33 g/ml. This means that a 600ml bottle must be above 200 grams and a 1500ml bottle must be above a weight of 500 grams. Experienced ecobrickers tend to regard 0.37 g/ml and above as the range of good ecobricks.

We've discovered that obligating minimum density in your community's ecobricking is essential to ensure quality ecobricks. Quality ecobricks ensure solid and safe constructions and maximize the bottle's volume for securing plastic out of the environment.

Ecobricks that are below 0.33 g/ml are too squishy to be used for modules and are not ideal for earth building. Soft ecobricks can compromise structural constructions and will dent easily, which reduces their lifespan. Low-density ecobricks are also fire hazards because of the air pockets remaining inside them.

That said, a good solid ecobrick that meets all GEA guidelines is something you can be proud of and which will inspire others! An ecobrick's heft and quality set an inspiring example for others and energize the social spread of ecobricks. When others see and hold your ecobrick, they will understand immediately that something important has happened: "waste" has been transformed into something fundamentally useful.

8. Cap and Log

Avoid packing your ecobrick too full.

Add a cap to your plastic waste packed ecoBrick

So your ecobrick is packed as solid as possible - now it's time to cap it! First, be sure your ecobrick is not packed to overflowing. There should be about 1-2cm between the cap and the plastic inside. The cap (HDPE) is made of a different type of plastic than the bottle (PET) and is the weakest part of the ecobrick. If plastic is even slightly pressing up against the lid, the pressure will inevitably crack it over the years. Also, be sure to avoid flip-tops or sports caps when sealing your ecobrick as they are fragile and will break easily over time.

Once capped, it is time to record your ecobrick! Recording your ecobrick's key data is an important part of ecobricking whether you're doing it on your own or as part of a community. This is particularly important for community leaders. You can use a log sheet, a spreadsheet, or the GoBrik app to record data such as the ecobricker's id, the final weight, date and year, the intended project, and serial number (generated by the GoBrik App).

Recording ecobricks is key to calculating your overall impact, monitoring quality, and preparing for building projects.

By recording the weight, you can tally up all your ecobricks and calculate the total plastic you have kept out of the environment. By recording id and weight you enable quality accountability. By maintaining a record of how many ecobricks you have completed, you'll know when you're ready to move to the building stage of your project. By recording the date you let people tomorrow know that we cared today about their world.

We've worked hard to craft a universal web app for you to use to log and connect your ecobricks with those in your community. Simply visit www.GoBrik.com with the web browser on your phone, sign in with Facebook or email, create an account, then begin to log your ecobricks. GoBrik will do the rest - compiling stats for you and your community.

We've also made a point-chart and sample form in our Vision Ecobrick Guide that can be photocopied for logging ecobricks in schools.

9. Inscribe

As you log and record your ecobrick, be sure to record the key data on the ecobrick itself too.

Log your eco brick on our gobrik app

Inscribing the weight, data, serial, etc. onto the ecobrick will indicate that the ecobrick has been logged and registered. Be sure to use a permanent means of recording your ecobrick. Your ecobrick will endure for decades and centuries. The more information we can leave future generations, the richer our gift. After much experimentation, we have found that enamel/oil paint and nail polish work best.

  • Avoid using paper labels, tape, or stickers to record the data. These methods will last for several years at best then fall off.
  • Avoid using permanent markers. Not only does their writing not last long on PET, they are made of non-recyclable and non-ecobrickable materials.
  • Enamel paint usually comes in a metal can or glass jar. These containers are effectively recyclable.
  • Use a paint brush to carefully and clearly inscribe the ecobrick's data. The paint bonds to the plastic and is almost impossible to remove.
  • Use contrasting colors like white and black to make your inscription stand out.
  • Nail polish is a form of oil paint and also permanently inscribes the ecobrick. However, often the nail polish brush makes it hard to write legibly. Also, the smell of the polish drying is strong.

Some ecobrickers are innovating with other methods; such as etching onto the ecobrick or inserting a written plastic tag into the bottle itself.

10. Store your ecobrick

Once complete, you will need to store your ecobricks until you have enough for your project.

how to store your ecobricks

Store ecobricks indoors, out of the sun. If possible, protect with a cloth or tarp from accumulating dust and dirt (PET attracts dust and chemicals and is hard to remove). Stack horizontally, with the ends pointed outward. This enables you to organize your ecobricks by colour and brand– which later facilitates project planning and making. It's good to have the ecobricks raised slightly above the floor — rats have been known to chew away at bottles! Ideally, ecobricks are stored off of the ground (on a pallet or raised on wood) and fully protected from the sun and the elements. Ecobricks are best stacked horizontally with their bottom pointed outwards.


And Build!

Once you have enough Ecobricks you’re ready to build. There are five main techniques for building with bottles and ecobricks. The easiest, fastest, and perhaps the most fun Ecobrick application, is to make Milstein modules for horizontal building and Dieleman Lego modules for vertical building.

With modules you can create benches, tables, chairs, structures and more. Perhaps the best use for Ecobricks is building community green spaces. Using local earth and ecobricks you and your community can build beautiful spaces that enrich the local environment.
