Reduce, reuse, reprint.

Although 90 percent of printer cartridges are recyclable, only 20 percent end up being reused. Planet Green offers a profitable remedy to that statistic. Send the company your used inkjet or laser cartridges and cell phones; they send you money. Inkjet models bring in as much as $5 a piece, laser cartridges are worth up to $16, and, if you've got a particularly fashionable cell phone, you could find yourself $150 richer. Between September 1 and October 31, the organization to send in the most qualifying inkjet cartridges will earn an additional $100.

"It's a great fundraiser for schools, nonprofits and religious organizations," says Program Director Renee van Staveren. Because Planet Green pays the shipping for inkjet cartridges, the company requires a minimum of 20 at a time. The minimum for cell phones is five, but laser cartridges can be sent in any number.

Another option is offered by The Ribbon Factory, which accepts your old cartridges and returns them full of new ink. The company works with dot matrix, inkjet and laser cartridges, and promises a 40 to 60 percent savings off market prices.

The quality of recycled cartridges used to be marginal, largely because hardware manufacturers use patented inks. Both Planet Green and The Ribbon Factory have solved this problem by allying themselves with manufacturers who produce comparable inks.
