Simplify Waste Sorting with Color-Coded Recycling Bins

Why Do Color-Coded Recycling Bins Exist?

You come home with a pizza box, a glass bottle, and an old newspaper. You know you need to sort the trash, but when it comes to the moment, you’re unsure: does this go in blue or yellow? And what about styrofoam? If this scenario sounds familiar, you’re not alone. Confusion during waste sorting is one of the main reasons why much recyclable material still ends up in Brazilian landfills.

The good news is that there is a standardized color system designed to simplify this process. In Brazil, the standard that guides the colors of solid waste bins is the ABNT NBR 10.004 combined with the guidelines of CONAMA Resolution No. 275/2001, which established the color code for different types of waste. Understanding this system is the first step to turning a confusing habit into something almost automatic.

In this article, you’ll learn what each color means, which materials belong to each category, and how to set up a practical sorting routine at home. With a few adjustments in daily life, you can make a real contribution to waste reduction — one of the greatest environmental challenges of our generation.

The Colors of Recycling Bins and What Each Represents

CONAMA Resolution No. 275/2001 defined a color standard to facilitate the identification of solid waste in Brazil. Here’s a summary:

Color	Type of Waste
🔵 Blue	Paper and cardboard
🔴 Red	Plastic
🟢 Green	Glass
🟡 Yellow	Metal
⚫ Black	Wood
🟠 Orange	Hazardous waste
🟤 Brown	Organic waste (food scraps)
⚪ White	Healthcare waste
Purple	Radioactive waste
Gray	Non-recyclable waste In the daily practice of Brazilian households, the most relevant colors are blue, red, green, yellow, brown, and gray. These are the ones that appear at recycling points scattered throughout cities and, ideally, in household bins. What Goes in Each Bin: A Practical Color Guide Blue Bin — Paper and Cardboard The blue color receives everything made of paper or cardboard, as long as it’s dry and reasonably clean. Wet or heavily greasy waste loses quality and complicates recycling. Can be disposed of: Newspapers, magazines, and paper sheets Cardboard boxes (crushed to save space) Long-life packaging without the separated internal plastic (they have their own recycling line) Cardboard egg cartons Envelopes and gift wrap (without metallic shine) Cannot be disposed of: Used toilet paper and paper towels Dirty napkins Photographs Carbon paper or laminated paper Red Bin — Plastic Plastic is one of the most common materials in household waste and one of the most environmentally impactful when improperly discarded. The red bin receives most of the daily plastic packaging. Can be disposed of: PET bottles (soft drinks, water, oil) Yogurt, margarine, and ice cream containers (clean) Plastic bags and plastic films Shampoo, conditioner, and cleaning product bottles (empty and rinsed) Straws and plastic caps Cannot be disposed of: Styrofoam (expanded polystyrene — has specific collection points in many cities) Disposable diapers Pan handles and other plastics mixed with rubber or metal Green Bin — Glass Glass is 100% recyclable and can be recycled infinitely without quality loss — one of the best properties of any material. The green bin receives general glass packaging. Can be disposed of: Glass bottles (beverages, oil, sauces) Preserve jars and jam jars Perfume and cosmetic glass bottles Attention: Broken glass should be wrapped carefully (newspaper or box) to protect collectors Do not mix with mirrors, window glass, lamps, or crystal — these have different compositions and do not enter the same recycling line Yellow Bin — Metal Cans, lids, and metal packaging go into the yellow bin. Aluminum is especially valuable: its recycling saves a significant amount of energy compared to producing primary aluminum from bauxite. Can be disposed of: Aluminum cans (soft drinks, beer, juices) Steel cans (tuna, sardines, tomato paste) Metal lids from bottles and jars Clean aluminum foil (crumple into a ball to facilitate) Old aluminum pans without handles Cannot be disposed of: Paint cans or chemical products (hazardous waste — orange) Packaging that still contains product Brown Bin — Organic Waste This is the most ignored category in Brazilian households, but one of the most important. About half of Brazilian household waste is composed of organic waste, according to data from the National Sanitation Information System (SNIS). When these wastes go to landfills, they produce methane — a very potent greenhouse gas. Can be disposed of: Fruit and vegetable peels Cooked food scraps Coffee grounds and tea bags Eggshells Plant trimmings and wilted flowers The ideal destination for organic waste is composting, which transforms these wastes into rich soil fertilizer. Many cities already offer selective collection of organic waste; others have drop-off points at fairs and markets. At home, it’s possible to set up a composter even in apartments. Gray Bin — Non-Recyclable Waste Gray is the “rest”: everything that cannot be recycled or composted. The goal is for this bin to be as small as possible. What goes here: Toilet paper and diapers Waste with a lot of dirt or grease that cannot be cleaned Broken broom handles mixed with various materials Mirrors and window glass (safely wrapped) Styrofoam (when there is no specific collection) How to Set Up Waste Sorting at Home: Step by Step Setting up a functional system doesn’t require much space or high investment. The secret lies in organization. Evaluate your space. Identify a location in the kitchen, balcony, or service area to place the bins. It doesn’t need to be large — cardboard boxes, cloth bags, or recycled buckets work well initially. Choose the number of divisions. For most families, three to four divisions suffice: dry recyclables (paper, plastic, metal, and glass together for drop-off at eco-points), organics, and non-recyclables. If your city has separate collection by type, it’s worth dividing more. Label each bin with the corresponding color or label. This helps the whole family, especially children, develop the habit. Clean the packaging before sorting. You don’t need to wash with soap — a quick rinse is enough to avoid odors and contamination. Crush and flatten packaging to save space in the bins. Find out the recycling collection points in your neighborhood. Many municipalities have eco-points, PEVs (Voluntary Delivery Points), and door-to-door collection. The city hall’s website or app usually has this information. Set a fixed day to take recyclables to the collection point or leave them on the curb on the right day. Regularity is what turns an isolated action into a habit. Special Waste: Where to Dispose of What Doesn’t Go in Common Bins Some materials need special attention because they contain substances that can contaminate soil and water if improperly discarded. Batteries and batteries: Should be taken to specific collection points — electronics stores, supermarkets, and pharmacies often provide these boxes. Expired medications: Many pharmacies participate in the safe disposal program. Never throw medicines in the toilet or common trash. Used cooking oil: Can be delivered to eco-points or collection stations. A closed PET bottle already facilitates transport. Electronics (e-waste): Old cell phones, chargers, and computers should go to electronic waste collection points. Many manufacturers have reverse logistics programs. Fluorescent and LED lamps: Contain compounds that require specialized disposal — check the nearest eco-point. Understanding how each material fits into a broader cycle of reuse and regeneration is part of the concept of circular economy, which proposes rethinking from product design to their end of life. Common Questions When Sorting Where does long-life packaging (Tetra Pak) go? Long-life packaging is made of paper, plastic, and aluminum. They have their own recycling chain and should be delivered to eco-points that accept this material or left in selective collection — many cities already collect them with dry recyclables. Can I mix all recyclables in one bin? Yes, if your city has selective collection that accepts mixed recyclables. Sorting is done at recycling centers. The most important thing is to separate dry recyclables, organics, and non-recyclables. Can dirty packaging be recycled? It depends on the degree. A container with a little residue can be rinsed. A pizza box soaked in grease, unfortunately, becomes waste — although the lid part, if clean, can be separated. Does styrofoam recycle? Yes, but it needs a specific point. Look for eco-points in your city or specialized companies. Conclusion: Small Choices, Big Difference Sorting waste correctly doesn’t require perfection — it requires consistency. Starting with three simple divisions (recyclables, organics, and non-recyclables) already represents a huge advance compared to throwing everything together. Over time, the habit consolidates and becomes easier. Each separated PET bottle, each correctly disposed aluminum can, and each composted food scrap is a concrete step to reduce landfill pressure, decrease greenhouse gas emissions, and conserve natural resources.
