Even when they’ve been emptied out, lighters will ruin recyclable materials. The gas residue will make it impossible for a recycling plant to safely process the metal or plastic. Additionally, if the gas gets on other items, they won’t be recycled. You may be able to find this information on your local government’s website, but many states don’t list information about lighter disposal online. This process applies to disposable and refillable lighters alike. It doesn’t matter if your lighter uses butane or lighter fluid.

Do not pour lighter fluid or butane down the drain. Even if you can physically access the fuel or butane, the gas will erode septic tanks and sewer lines. It may also damage the environment, even after the gas is filtered at a water treatment facility. [3] X Research source

A household hazardous waste site, often abbreviated HHW, is a dedicated waste facility that disposes of items one at a time to ensure that local laws are followed and safety standards are upheld. Items at these sites are typically incinerated or destroyed, but it’s still safer than throwing your lighter in the trash.

Some cities and states have a search engine on their website to make it easier to find an appropriate disposal site.

This service is always free.
