Blue Container
The blue container, like the yellow container, was one of the first bins introduced for selective waste collection—another key pillar of the recycling process. Thanks to it, we can give new life to materials, avoid unnecessary tree felling, and reduce environmental impact.
What can you throw in the blue container?
The blue container is exclusively for paper and cardboard waste. Make sure to only dispose of materials that can truly be recycled to avoid contaminating the recycling stream.
You can dispose of the following items in this container:
-
Newspapers, magazines, and brochures: From daily newspapers to promotional catalogues.
-
Cardboard boxes: Cereal, shoe, cookie, electronics packaging, and shipping boxes.
-
Paper sheets: Printed documents, old notes, or letters.
-
Paper bags and envelopes: As long as they don’t have plastic windows.
-
Notebooks: Only if metal or plastic spirals are removed.

Why is it important to recycle paper and cardboard?
Recycling paper and cardboard is one of the easiest and most effective actions to help the planet.
-
Prevents deforestation: A full container of recycled paper can save several trees.
-
Saves water: Producing recycled paper uses much less water than making it from virgin pulp.
-
Reduces energy consumption: Making recycled paper requires up to 60% less energy than producing it from scratch.
-
Less pollution: The paper industry is one of the most polluting sectors when not using recycled materials.
What should not go in the blue container?
Not all paper and cardboard can be recycled. Some items must be taken to different bins or a recycling center.
Avoid putting these in the blue container:
-
Waxed or laminated paper: Such as deli or butcher paper.
-
Dirty paper towels or napkins: These belong in the brown (organic) container.
-
Pizza boxes or packaging with food residue.
-
Tetra Briks: Although they contain cardboard, they go in the yellow container.
-
Photographs.
Tips for recycling correctly in the blue container
Recycling paper and cardboard is simple, but these practices improve the process:
-
Flatten boxes: To save space in the bin and facilitate collection.
-
Remove staples, tape, and plastics: Although some machines can separate them, it’s best to do it beforehand.
What happens to paper and cardboard after recycling?
When you place paper and cardboard in the blue container, it is collected and sent to recycling plants where:
-
Impurities such as plastics, metals, or non-recyclable waste are removed.
-
It is shredded and mixed with water to create recycled pulp.
-
Inks and adhesives are removed through chemical or mechanical processes.
-
The mixture is centrifuged to separate materials based on density.
-
New paper pulp is formed, then dried and pressed into sheets.
-
Recycled paper and cardboard are manufactured for newspapers, boxes, notebooks, and more.
Properly separating paper and cardboard helps protect the environment, reduce pollution, and promote the circular economy.
