The worst product ever marketed: the disposable butane lighter. Wasteful, expensive, non-recyclable, using non-renewable materials, having benign alternatives (matches). In short, evil. And yet, it was hugely successful. Image from Wikipedia.
The disposable lighter is surely practical but also, if you think about it, a very bad deal. It contains some 5 cc of butane, that you pay, typically, more than $1. That means around $200 per liter, or $800/gallon. You wouldn't be happy to pay that kind of money when you refill the tank of your car. And, being powered by a fossil fuel, butane, every time you light up one you add some CO2 to the atmosphere, some of which will stay there for tens of thousands of years.
Then, the disposable lighter doesn't contain just non-renewable fuel but plastics manufactured from fossil fuels and also polluting. Then, it contains metals such as cerium, lanthanum, neodymium, praeseodymium and more. These metals are classified as "rare earths;" they are not so rare as the name seems to imply, but they are not so common, either. And the lighter is thrown away after use and it will never be recycled. The rare earths it contains will be lost forever.
Is all that enough to qualify disposable lighters as "the worst product ever marketed"? Well, everything can be questioned, but if you line up the characteristics of a bad product as 1) uses rare and non-renewable resources, 2) is not recycled and not supposed to be recyclable, 3) is manufactured on a large scale, 4) it has non-polluting and less expensive alternatives, there are few examples other than lighters for which you can tick all the four boxes. I can hardly think of anything so wasteful to set something on fire, no matter whether you are a professional arsonist or simply an ordinary smoker.
After all, what was so wrong with using the old matches? Matches contain only recyclable materials: wood, paper, phosphorous, sulfur. I can't see anything that can be done with a lighter that cannot be done with a match, except that a lighter can burn steadily for a longer time. But if your purpose is to light up a cigarette or a kitchen burner, it makes no difference. And, by all means, there is no way that a lighter would cost less than a match, at least if manufactured on a comparable scale.
So, disposable lighters are all an example of how a combination of financial factors and government regulations can push a bad product to dominate the market. It is, after all, what has happened with fossil fuels, still gathering large government subsidies, despite the damage they are doing to all of us.
In the case of lighter vs. matches, the playing field has been made unfavorable to matches from the beginning, because they have been traditionally taxed by governments (also lighters, in some cases, but not always). Add to that the rapid expansion of the cigarette market during the past decades, with some six billion cigarettes sold worldwide every year, and growing, some large companies saw their chance. They engaged in the large scale manufacturing of lighters and they crushed the match manufacturers, mainly small companies that couldn't match (indeed!) the financial power of large corporations. The advertising power, too, played a big role, with the appeal of colored and fashionable items that could also be collected. And it was world domination for the disposable lighter.
Could we reverse this demonic trend? Maybe there are signs of an inversion of the tendency and, not long ago, I saw again courtesy matchboxes appearing in an Italian Hotel. Maybe it was because finally (in 2015) the Italian government decided to abolish the tax on matches, a good idea that, unfortunately, arrived at least 50 years too late (the French Government did that in 1999). Whatever the case, it is high time that someone realizes that some ideas, such as disposable lighters, are evil to the bone. And that the mythical "free market" cannot turn evil into good.
But maybe you think that the old matches are passé? In this case, we have technologies for getting rid of the obsolete propane lighters without having to get back to the somewhat primitive matches. For instance, we have spark lighters that use only electricity. They are a solid state alternative to propane lighters in the same way as photovoltaic energy is a solid state alternative to fossil energy. In the picture, you see one of these super hi-tech lighters in the hands of my daughter, Donata.
So, eventually, we learn what's the good way to do things. Too bad that it is almost always too late.
