I can't believe I didn't know this before! Did you know that tons of places will reward you for recycling your printer cartridges? My daughter's school send a note home last week asking parents to send their spent printer cartridges to school and the school can get paid for them! And here we've been throwing tons of them away.
We used to have epson printers that gobbled up ink and it seemed like we were buying new ones every couple of weeks or so. Even when we switched to printers that used up less ink, we still ended up throwing away bagfuls of empty printer cartridges. Now I'm glad we found another useful purpose for them than to just clog up the landfills.
