Karlos Arguiñano doesn't hold his tongue. A few months ago, he once again spoke clearly about a topic that affects everyone: the misuse of cooking oil once it's been used. With his usual tone, direct and straightforward, he left a statement that many have quickly commented on: "90% of people used to pour dirty oil down the sink."
The chef from Zarautz is referring to a habit that is still very present in many homes. After frying, many people still pour the oil down the drain. It's a quick, convenient gesture, but it's completely discouraged. "There will be those who keep doing it and won't care, but that's truly disgusting," he said to the media.
His words aren't an exaggeration. Pouring used oil down the sink causes clogs, bad odors, and problems in the pipes. But the most serious issue is its environmental impact: a single quart (1 liter) of oil can pollute up to 264 gallons (1,000 liters) of water. The figure is as alarming as it is real.
Arguiñano wanted to go beyond criticism and also gave the solution. First: let the oil cool; then, store it in a closed container. Finally, take it to a recycling center or specific container, something that doesn't take much effort and makes a difference.
Many city councils already offer alternatives. From orange containers on the street to collection at recycling points or even gas stations. But the reality is that less than 10% of household oils are still being recycled. The rest, for the most part, ends up being poorly managed.
Karlos Arguiñano and the other risk
Besides the environmental damage, there is a legal risk. Current regulations penalize pouring oils down the sink. Fines can reach €100,000. It's a figure that might seem exaggerated, but it's meant to stop a massive problem.
The chef, far from sounding imposing, appealed to common sense. "This isn't about being perfect," he said, "it's about using your head a little. If you don't do it for yourself, do it for those who come after you," something that, in a few words, is about collective responsibility.
Arguiñano took the opportunity to remind everyone that cooking also means caring. It's not just about preparing delicious dishes. You also have to respect food, resources, and the environment. It's something he has been preaching on television for decades.
It's not the first time the Basque chef has raised his voice on sustainability issues. He has already given advice on avoiding waste, shopping wisely, and choosing local products. Now, he's focusing on used oil. It's a dangerous waste that, if poorly managed, causes havoc.
In an era where everything is recycled, it doesn't make sense to keep pouring oil down the sink. It's not an innocent gesture. It's a mistake that can be costly. Literally.
With his usual mix of humor and common sense, Arguiñano once again leaves a clear message. Small gestures, if done right, make a big difference. This one, even if it seems minor, starts at home and affects the entire planet.
