But the industry that's inviting us to get a new cell phone every year and toss out that old TV in favor of a great new flat panel is also trying to show that it cares.
Many of the products on display will be striking rather small blows for the environment, but the industry is realizing that even in electronics, going "green" can be a powerful marketing tool.
"Everything I've heard from folks out there is that there is going to be a lot of emphasis on green this year," said Scot Case, a vice president at consultancy TerraChoice Environmental Marketing Inc.
One of the 2,700 exhibitors at the International Consumer Electronics Show will be Japan's Fujitsu Ltd., which will show off a laptop with a plastic case made from corn rather than petroleum products. The company has sold such a model in Japan since 2006, but is now considering taking it to the North American market.
Environmental awareness among consumers and corporations has now reached the point where manufacturers really are taking notice, said Richard McCormack, senior vice president of marketing at Fujitsu's U.S. arm.
"They're driving manufacturers like us with their pocket book," McCormack said.
The catch with the corn-based laptop is that the material isn't biodegradable, meaning it doesn't decompose any faster than regular plastic. That's because it still contains some petroleum-based plastic in the mix for rigidity. The plastic still needs to be processed for recycling, after which the corn-based component can biodegrade.
Another company attacking the recycling angle is Z-Power, which has developed a battery technology that it hopes will replace the lithium-ion batteries that power today's laptops and cell phones.
Its silver-zinc batteries will show up in laptops from a "major" manufacturer in the summer, according to the Camarillo, Calif., company's chief executive, Ross Dueber.
Lithium-ion batteries are recyclable but contain little recoverable material. The metals in Z-Power's batteries will be recoverable, Dueber said, and with a precious metal like silver in them, there will be a strong incentive to do so. The capacity should be 20-30 percent higher than lithium-ion laptop batteries. The company is also in discussions with cell-phone manufacturers.
Only a few manufacturers, like Sony Corp., take responsibility for recycling their products. 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 dumped rather than recycled.
At the show, the EPA will be announcing a campaign to provide consumers with more places to turn in cell phones for recycling, in partnership with manufacturers and retailers. The agency puts the number of unused cell phones lingering in drawers at 100 million.
Also at the show, manufacturers are expected to trot out computers, especially laptops, that meet the EPA's new, tougher Energy Star 4.0 power consumption requirements, which went into effect in July.
The specification now sets maximum levels for power consumption when the computer is on but idle — previously, Energy Star dealt only with the ability to enter "sleep" mode.
There won't be many desktop computers qualifying for the Energy Star rating — their power consumption is growing, with many now hitting 400 watts.
Marvell Technology Group Ltd. will be demonstrating chips for power adapters that it says can curb that trend, by convert alternating current into the direct current in a more efficient way, potentially power consumption by half.
