Rule out look-alike items from envases and prepare packaging the right way.
Yellow-container impostors
Looking like packaging doesn't make it packaging
The items that most often end up in yellow by mistake. None of them ever packaged anything.
— toys, hangers, plastic basins, buckets, kitchen utensils, cutlery;
— toothbrushes, pens, lighters;
— CDs, DVDs, cassettes;
— rubber gloves, school supplies, cables.
Small items from this list go in resto. Only large, electronic, or hazardous ones go to the punto limpio: appliances, cables, a battery-powered toy, paint.
Why it matters: the sorting line is tuned to packaging — optical sorters, a magnet, and an eddy current separator. A toy of mixed plastics with a metal axle matches none of them and ends up in rechazo, the rejects.
WHAT DOES GO IN YELLOW, SURPRISINGLY:
— brik (milk and juice cartons) — yes, yellow, not blue;
— empty aerosol cans and deodorant sprays — they're metal packaging;
— supermarket bags — plastic film packaging;
— white foam trays from meat and fish;
— metal lids from glass jars.
But a trash bag isn't packaging: it goes in resto with its contents.
ONE SYMBOL THAT FOOLS ALMOST EVERYONE. The Punto Verde, the green circle of two arrows, doesn't mean recyclable or “toss it in yellow.” It only means the producer paid a fee to the responsibility scheme (Ecoembes or Ecovidrio): a financial mark, voluntary since January 1, 2025. Go by the label “Contenedor amarillo” or “Contenedor azul,” mandatory since that date: that one tells the truth.

Three questions everyone asks
RINSE PACKAGING? No. Ecoembes explicitly calls it a mistake — “gasto innecesario de agua.” It gets washed at the plant anyway. There's one requirement: the packaging must be empty.
TAKE THE CAP OFF A PLASTIC BOTTLE? No, leave it on. Caps are made of polyethylene and polypropylene; they're recycled together with the bottle, while on their own they get lost on the line. What's more, since July 3, 2024, an EU rule has required the cap on drinks of up to 3 L to be physically attached to the neck — tapón unido. The reason: caps turn up in marine litter 2–3 times more often than the bottles themselves.
A GLASS JAR IS THE OPPOSITE: take off its metal or plastic lid and put it in yellow, and put the jar itself in green. The asymmetry is confusing, but the logic is simple: in a glass furnace, metal and plastic cause defects, while on the packaging line a plastic bottle's cap travels in the same stream as the bottle.
CRUSH THE BOTTLE? Yes, top to bottom, so it takes up less space. No need to remove the label.
And one thing about the blue container: fold boxes flat. Ecoembes calls not folding them one of the main mistakes — otherwise garbage trucks haul air, the container overflows, and a pile grows around it, which Madrid fines as a grave (serious) offense, from €751.
