Photocatalyst makes books not stink

People with multiple chemical sensitivity (like me) know how serious a problem scent pollution can be – as do scientists at NASA. In the Space Shuttle, odors are boiled in the sunlight, which can amplify them to horrific volume. The cheap (but time-consuming) solution is simply to let the smell fade naturally through offgassing, but if you want to keep ink chemicals out of your home, you can seal them in with photocatalyst. You mix a titanium oxide-based photocatalyst with resin, and spread it on the paper. This decomposes all volatile organic compounds (VOCs) lickety-split so you don’t get sick building syndrome (or sick Space Shuttle syndrome). 3 yen per A4 sheet. [GT]

No more smelly books
