Used toner cartridge? Sit on it

Here’s a creative new use for those spent toner and ink jet cartridges. It’s true that some vendors have a cartridge return program where they can re-use or recycle them, but many do not. It’s especially bad on the off-brand toner and ink market. What’s an eco-conscientious user to do?

Now a UK recycling company called Waycam has a new idea – they use a process that transforms cartridges into a plastic called TRI Wood, and then turn it into fence posts and garden furniture.

While the furniture aspect is a great stunt, the serious issue, as they acknowledge, is recycling the (highly toxic) used toner. It’s another step in the effort to keep more toxins out of landfills. This kind of thing is becoming increasingly a legal necessity in Europe, and it is something that should spread in the near future to the US.

Health and laser printers

A recent Australian study of office air quality raised some concerns about laser printers, more specifically the toner particles emitted by them. This so-called “ultra-fine particle pollution” can contribute to respiratory illnesses, much like having secondhand smoke from a nearby indoor smoker, something no office these days permits. As one of the scientist from Queensland University is quoted as saying “If a printer operates in an indoor environment, the concentration of ultra-fine particles would be of the same order of magnitude as if there was secondhand smoke in a similar environment.”

The curious thing is that some laser printers emit no or little toner, while others emit a high level. And even printers from the same vendor can range from totally clean to polluting. While all printers pass federal safety and health regulations, the Australian study points out a new area for concern.

The Australian group is still continuing its studies (they have found, for example, that copiers are generally less of a problem), and they may well discover why some printers emit give off more particles than others. There may be a manufacturing fix that can lower the particle count on the worst offending machines.

In a practical sense, offices should become more aware of general ventilation and air exchange, something that would be useful in general, for cutting down on colds and other air-borne viruses.
