NEW YORK — We think a lot about getting new gadgets, but not so much about getting rid of old ones. The result: old cell phones, defunct laser printers and Pentium III computers gathering dust. And potentially contaminating the environment if they're eventually dumped into landfills.

A couple of companies want to help us clear out those old gadgets, while feeding our upgrade habit, helping the environment and making a buck.

Instead of being hit up for an extended warranty next time you buy a gadget, you may find yourself hearing a pitch from TechForward Inc., a Los Angeles-based company selling a "guaranteed" buyback plan.

For a fee paid when you buy a device — $9 for an iPod, for instance — you get the right to sell it to TechForward at a predetermined price that depends on how long you keep it. If you sell an iPod after a year, for example, you get $40; after another year, $20.

In the financial world, this is known as a "put option" — the opportunity to sell a certain number of shares at a certain price at a certain date in exchange for an upfront fee. But Jade Van Doren, TechForward's chief executive, said his inspiration came from traveling in Asia, where gadget worship is even more pronounced and some consumers buy new cell phones every few months.

"I just started thinking about ways that you could build a company around ... encouraging people to live that lifestyle of temporary ownership," he said.

The trade-in prices don't look competitive with eBay auctions, but TechForward offers the convenience of free packaging and shipping. Its prices assume the item is in good condition. The company won't pay for an item that's broken, though it will supply packaging, pay for shipping and arrange to recycle it.

So far, TechForward's partners are small West Coast retailers. They get a share of the initial fee and can count on repeat business from customers who trade in their old gadgets.

Techforward claims participating stores are selling its guarantee with 12 percent of eligible gadgets.

NEW Corp., a much larger company that runs extended warranty programs for Best Buy Inc. and Wal-Mart Stores Inc., plans to bring a slightly different idea to stores in the second quarter.

The ecoNEW program — which amounts to a vast expansion of the trade-in programs some retailers run, mainly as promotions — won't charge upfront like TechForward.

It will provide store credit for old electronics in some categories, such as computers, MP3 players and smart phones — with the dollar amount depending on the market for the particular equipment when it's traded in.

Some items, like printers and non-LCD monitors, won't qualify for credit, but users will be able to send them in free for recycling.

"We've got the green contingent in the company screaming for this solution and to make it as altruistic as possible," said Dan Hulkower, vice president of client management at Sterling, Va.-based NEW.

The program will be offered by retailers — NEW can't yet say which — so customers will go to those Web sites or stores to return things. With no receipt necessary, they will be able to return things bought from other stores.

It's reasonably easy to resell working, high-value electronics through eBay, but it has been hard for consumers to dispose of defunct or obsolete items in an environmentally safe manner. These programs hope to held with that. Just 12.5 percent of U.S. electronics waste is offered for recycling each year, according to the Environmental Protection Agency, and much of that is actually dumped rather than recycled, the EPA says.
