Tiny bits of toner wafting from laser printers can't be blamed for polluting indoor air, according to research released this week.
In 2007, a study from Queensland University of Technology in Australia suggested that breathing toner particles from printers could hurt the lungs as much cigarette smoke.

Researchers examined laser printer emissions in an enclosed area.
(Credit: Fraunhofer-Gesellschaft)But researchers from that school and the Fraunhofer Wilhelm Klauditz Institute in Germany have found no evidence to support that claim, after examining the makeup of chemicals released from laser printers.
They determined that such airborne materials include paraffins and silicon oils that evaporate when a printer's fixing unit, which attaches dry toner ink to paper, reaches temperatures as high as 428 degrees Fahrenheit.
"One essential property of these ultra-fine particles is their volatility, which indicates that we are not looking at toner dust," said Tunga Salthammer, a professor who worked on the study, in a statement.
The study did not describe how breathing in the ultra-fine chemicals could affect human health. However, volatile organic compounds are a major source of pollution indoors, where they are found in the air at levels up to 10 times higher than outdoors, according to the Environmental Protection Agency.
The nonprofit GreenGuard Environmental Institute offers a directory of electronics that emit relatively few of such chemicals, but that does not include printers. Last year's Australian study identified printer models with the highest emissions.
Add-on filters would do little to prevent printer emissions, according to researchers participating in the latest study, who noted that volatile organic substances are also released into the air from other household activities, such as toasting bread and cooking.
Printer makers belonging to the German Association for Information Technology partly funded the research.
German lawmakers plan to talk about the potential for laser printers to cause health problems at a meeting in January , according to Heise Online.

When it comes to European Union efforts toward a climate action plan, the devil, it turns out, is in the details.
All of the member states of the EU are willing to commit their countries to draw 20 percent of their energy from renewable resources, reduce CO2 emissions by 20 percent, and become 20 percent more energy efficient by 2020. That overall goal was agreed upon in March 2007.
In January 2008, the agreement was refined with more details including action plans in different categories for countries to follow. One of these demanded that 10 percent of all road transport fuel come from renewable resources by 2020. According to that January proposal, the majority of renewables would be allowed to be from biofuels.
Concerns were raised over the global impact of biofuels, and the entire package became deadlocked over the issue.
You can read the drama of this on the blog of Andris Piebalgs, the EU energy commissioner who's also repeatedly addressed the fierce European debate over biofuels.
As anyone who's read anything about biofuels in the last few years knows, it's a controversial topic not just in Europe but everywhere.
Some see biofuels as a permanent addition to the go-to list of energy sources and deny they're responsible for any food shortages. Others see it as a reasonable midterm solution until better technology can be implemented. Many countries with a heavy agricultural base covet the lucrative market and money it can bring their people.
Others raise concerns that biofuels are responsible for soaring food prices and shortages, since food producers are forced to compete against energy companies for grain supplies. Arguably, the growing world demand for those crops are also responsible for indirect land-use change--the destruction of wetlands and rain forests to make room for more farmland.
Taking these views into consideration, EU members finally settled on a tentative deal over the biofuels issue on Thursday.
A third of the 10 percent of road transport fuel required to come from renewables must be from electric cars and trains.
But Italy still blocked the deal from passing. (The European Parliament and all 27 EU nations have to approve the deal in order for it to become a law.)
Italy wants a clause included in the final agreement that would allow countries to review the policy again in 2014.
Both environmentalists and EU member countries against the clause argued it would hold up investment in alternative energies. With an escape clause, they say, alternative energy investors will take a wait-and-see approach until 2014 in case parts of the EU energy plan are dumped.
French Prime Minister Nicolas Sarkozy, who is also the current president of the EU, announced that the proposal will be revisited on December 11 and 12 at the European Council meeting in Brussels.
(Credit: Virgin America)Virgin America announced Thursday it will offer customers the option to pay a voluntary fee when booking their ticket, which will go toward supporting carbon offset projects.
The U.S. domestic airline based in California, of which Richard Branson's Virgin Group is a minority share investor, has partnered with Carbonfund.org on the effort.
Through Carbonfund.org, the money Virgin America collects from consumers will be directed toward projects sanctioned by the Environmental Defense Fund's (EDF) official CarbonOffsetList.org.
One of the projects from that list that Virgin America chose to support, for example, is IdleAire.
IdleAire lets truckers connect their cabins to electricity sources at rest stops, rather than keep their engines idling to keep their power on. The process saves each trucker about a gallon of diesel per hour, according to Virgin America.
While IdleAire sounds like a practical project, it's questionable whether consumers will go for it.
Many other airlines have tried offering carbon offsets with lackluster results. Virgin Atlantic, admitting its online option wasn't getting many takers, announced last year it would try guilt by offering an offset in the air alongside the drinks.
Consumers could get nitpicky about each individual project. Donating to IdleAire sounds fine, but where is that electricity the truckers' tap into coming from? Is the local electricity being used generated from a renewable resource or coal?
There's also the world food shortage, and many poverty and disease-fighting nonprofits struggling from a lack of available charity due to the tough economy. Consumers might place environmental causes at the bottom of their charity list if they themselves are limited to what they can give this year.
Then, again, it's been argued that some water and food shortages can be directly linked to environmental changes in those problem areas. Will consumers feel there's a long view to be seen and donate toward offsetting pollution with that hope of improving things down the road?
Perhaps more promising is the second tact Virgin American plans to take.
While it's not in place yet, the airline plans to offer an onboard option. Through the touch-screen televisions on their flights, consumers will have a second chance to donate once their flight is already in the air.
Will a view of the clouds (and the occasional smog ruining skyline views) shame the guilty into donating? I'm just not sure.
After all, with Virgin America's new Gogo in-flight Wi-Fi service, consumers could just as easily donate online to another cause if they're feeling charitable while airborne.

Editors note: This is part of a series of stories about the recession's effect on the tech industry.
On paper, things couldn't be much better for Bruce Jamerson. As CEO of Mascoma, he runs an ethanol company staffed by brilliant scientists, wooed by state governors, and amply funded by General Motors and leading green-tech venture capital firms.
But late last month, he made the painful decision to shed staff in an effort to control costs. Even though Mascoma's a private company, there is no escaping the trickle-down effect of the skidding stock market.
Mascoma CEO Bruce Jamerson
(Credit: Mascoma)"Because we're not going to have commercial operations for several years, we need to make sure that our cash lasts as long as we can," Jamerson said. "All companies in the clean-tech sector should be considering this."
Many already are. After being lavished with attention and money for years, many green-tech entrepreneurs--the foot soldiers in a hoped-for clean-energy revolution--are being forced to shift into low gear.
The recession and slumping financial markets are choking the flow of money, which is the lifeblood of fledgling green outfits. Meanwhile, lower economic activity is causing fossil fuel prices to plummet, making some green businesses a tougher sell.
Green-tech entrepreneurs do have other options for getting money beyond traditional venture capitalists and angel investors, such as government loans or state grants.
But the same danger signals that Silicon Valley venture capitalists have broadcast to Web start-ups applies to green tech as well.
"There is such compelling logic behind a lot of the technologies, but there is a real hunkering down going on," said Mark Barnett, an attorney at Foley Hoag's clean-tech practice. "If you're a venture capitalist, to give a company more money, you have to believe they can weather the storm...and be one of the first out of the gate when things clear."
From Wall Street to South Dakota
Unlike many people who have jumped into clean tech over the past few years, Mascoma's Jamerson, who's in his early 50s, knows quite a bit about the fuels business and finance.
A year and a half ago, he was president of Sioux Falls, S.D.-based VeraSun, which grew to be one of the biggest ethanol makers in the country. He was chief financial officer until it went public in 2006, when investors' love of ethanol made it a hot stock. (It recently filed for bankruptcy.)
His financing chops come from working on Wall Street, where he engineered investment banking deals for 10 years before abandoning it all to run a boutique investment firm in Oregon.
After being VeraSun president for almost a year, he resigned last February to join a little-known start-up called Mascoma, not bothering to take a vacation day in between jobs.
He was lured to Mascoma--prodded by high-profile investor and board member Vinod Khosla--because of its technology, he says. Using genetically modified microbes, Mascoma promises to make ethanol cost-effectively from non-food feedstocks, like wood chips.

(Credit: Mascoma)Like many people in the clean-tech business, Jamerson sees his small ethanol firm as part of a larger clean-technology movement to encourage domestic fuel production and reduce greenhouse gas emissions.
He says Mascoma is at the "edge of the wedge," the intersection point of many trends, including high energy prices, climate change, and policies promoting energy security. It's considered one of the front runners in the race to make ethanol from non-food sources.
Caution after a great run
Cracking the nut on cellulosic ethanol is one of the biggest technical hurdles to meeting government renewable fuel mandates and improve the public image of biofuels.
"There are a lot of places in the world where the appetite is very strong for this type of product," he said at a Mascoma lab tour in Dartmouth, N.H., where Mascoma was first hatched.
Indeed, on the whole, the company has had a great year. General Motors and Marathon Oil invested in the firm and became strategic partners. Michigan and New York, eager to diversify into renewable energy, have given Mascoma grants to build pilot plants. Technically, Jamerson said that Mascoma's ahead of schedule in meeting its milestones.
But even buoyed by all that optimism, Jamerson and the company's board decided it had to lay off employees, including its president and a number of vice presidents.
"These are hard decisions. The way I'm thinking about it, I'm being conservative with my expenses," he said. "It just so happened that the reductions were skewed toward a couple of senior people."
Rather than have to make more cuts in six months, he decided that it was better to have a cost-reduction plan now. Its plans to build pilot plants in Michigan and New York are not in jeopardy; the cutbacks were made so that the company could continue hitting its goals, Jamerson said.
Not every green-tech entrepreneur is in the same boat. Companies that need late-stage funding, to finance a solar manufacturing plant or biofuel refinery, are perhaps in the toughest spot.
Businesses that focus on energy efficiency, for instance, stand to do well as companies look to save money, whereas biofuels like ethanol are more closely linked to falling prices of gasoline.
But it's the disarray of the financial markets that has Jamerson most concerned. Mascoma had planned to go public in the next two years, but that's a lot less certain these days.
"That window has been closed for now and with institutional investors being more cautious, we need to be cautious," Jamerson said. "We need to get through this period of time."
Coming up Friday: Survival of the fittest for IT companies
Makers of mobile phones produce few "green" models with biodegradable, recycled, or fully recyclable materials. And although most vendors offer recycling options, less than five percent of the world's handsets will be recycled ethically in the end, according to a report released by ABI Research Monday.
Cell phones are a growing source of potentially toxic electronics waste. Among some 150 million handsets retired every year, fewer than 20 percent are recycled, according to the Environmental Protection Agency.

Nokia's Remade concept phone would use recycled and recyclable materials inside and out.
(Credit: Nokia)However, it's unprofitable for most companies to release dedicated eco-friendly models on a massive scale, the ABI report suggested.
"Instead, the effort is towards compliance and the trickling down of proven green elements throughout entire product lines," Kevin Burden, the firm's research director, said in a statement.
Expanded regulation and corporate initiatives have reduced the use of toxic ingredients in electronics. The European Union's Reduction of Hazardous Substances rules have pushed nearly all major vendors to cut or exclude heavy metals, PVC, and brominated flame retardants.
ABI Research cited Samsung, Nokia, and Sony Ericsson as advancing efforts to make mobile phones even greener. Those brands also were at the top of the heap in the latest quarterly Greenpeace Guide to Greener Electronics.
Samsung released three models encased in corn-based plastic this summer in Asia and Europe.
Among this year's concept designs, Nokia's Remade flip phone cell uses recycled cans, plastic bottles, and car tires. Nokia says that up to 60 percent of the metal in its available handsets comes from recycled materials.
Sony Ericsson described in September a GreenHeart concept comprising recycled and plant-based plastics. If produced, it would consume only 3.5 milliwatts in standby mode.
A notable entrant in this year's Greener Gadgets Design Competition was the Bamboo concept handset. If buried in the ground, it would biodegrade, freeing embedded bamboo seeds to sprout a plant.
The ABI report notes a Nokia survey in which 76 percent of respondents said they preferred to buy from businesses that promote environmental responsibility.
Various other consumer polls have indicated that a small but growing percentage of shoppers seek to buy green electronics, and some will accept a price premium.

A variety of off-grid devices use the wind, the sun, or fuel cells to power up small electronics. But what if you could charge your cell phone just by talking into it, eliminating the need for batteries or cords?

What if power cords and batteries were a thing of the past?
(Credit: CBS Interactive)What would make this possible is piezoelectricity, in which a mechanical force is converted to electricity. Some cigarette and barbeque grill lighters are an example. When a button is punched, pressure on a crystal within produces voltage, creating a spark.
In principle, the pressure to power a device could come from sound vibrations.
Crafting such piezoelectric electronics would require sensors with a specific size of crystal or ceramic material. Engineers say they have taken an early step by identifying a sweet spot at which a crystal could produce energy.
The capability of barium titanate crystals to harvest power doubles when they're about 23 nanometers in size, according to an analysis led by engineer Tahir Cagin at Texas A&M University. A human hair, for contrast, is about 100,000 nanometers wide.
However, it could be years or decades before scientists and entrepreneurs apply the findings to consumer products, he said.
"There are limitations to how much power you can generate at a given size," said Cagin, adding that an iPod or cell phone may require nano-sensors at a scale and composition different from what his research suggested.

The Better Place Rogue is an all-electric version of the Nissan Rogue crossover SUV.
(Credit: Better Place)Hawaii has decided to partner with Better Place to bring car battery exchange stations for electric vehicles to the islands, Hawaii Gov. Linda Lingle announced Tuesday.
Better Place stations, similar in concept to gas stations, offer drivers with electric vehicles an automated system that swaps out exhausted lithium ion car batteries for fully-charged ones. The swapping system is intended to be convenient for both drivers and local electric companies, since Better Place can recharge the exhausted batteries with excess electricity generated from renewable sources during off-peak electricity hours.
Lingle said the project is an example of Hawaii's efforts to gain independence from foreign oil, and to stimulate its economy through investment in energy technology.
Not surprising due to its geography, Hawaii spends about $7 billion a year on oil imports with its drivers facing some of the toughest prices at the pump in the U.S. The plan to implement Better Place stations coincides with the Hawaii Clean Energy Initiative (HCEI) intended to change that. Signed in January, it sets Hawaii's renewable energy bar at 70 percent clean energy by 2030, as well as encouraging programs that foster local economic growth.
Shai Agassi, founder and CEO of Better Place, was also on hand at the plan unveiling in Hawaii on December 2. According to Agassi, Hawaii is the second state in the U.S., and the fifth place in the world, to adopt the Better Place electric-car infrastructure. Better Place stations have already been implemented in Denmark and Israel, with Australia and California recently announcing intentions to add them.
"Hawaii, with its ready access to renewable energy resources like solar, wind, wave, and geothermal, is the ideal location to serve as a blueprint for the rest of the U.S. in terms of reducing our dependence on foreign oil, growing our renewable energy portfolio and creating an infrastructure that will stabilize our economy," Agassi said in a statement to the press.
Hawaii Electric is also onboard. The state's electric utility signed a Memorandum of Understanding (MOU) with Better Place which plans to power its public charging and battery-swapping stations with renewable energy resources.
According to the plan, Better Place will pull permits for its stations in 2009, offer electric cars within 18 months, and make both available for the mass-market in Hawaii by 2012.
Better Place has said it's in talks with major automakers and would like to offer swappable batteries for any electric vehicle regardless of which company makes the car. But right now the company's stations only service two electric vehicles: the Renault Megane and the Better Place Rogue, an electric vehicle based on the Nissan Rogue crossover SUV.

Hawaii's plan with Better Place is to install about 20 electric battery-swapping stations across its islands.

Ford Motor made electric vehicles a centerpiece of a turnaround plan presented to Congress on Tuesday, saying that it will introduce an all-electric van for fleet use in 2010 and a sedan in 2011.
The Big Three U.S. automakers are scheduled to return to Washington, D.C., this week with the hopes of negotiating loans to forestall a collapse from lack of cash.
All three companies are seeing a continued dip in sales, but Ford is considered far better off financially than General Motors and Chrysler. Ford on Tuesday said it could be cash-flow positive from operations by 2011, but it is still requesting up to $9 billion in loans, which CEO Alan Mulally said will act as a "critical backstop or safeguard against worsening conditions, as we drive transformational change in our company."
The business plan lists cost reductions--including plant closings and the sale of its much-criticized corporate aircraft--and investments in smaller, fuel-efficient cars and a line of electric vehicles.
Its product plans calls for:
A commitment to improve fuel efficiency across its fleet: 14 percent for 2009, 26 percent for 2012, and 36 percent for 2015--all compared with 2005 overall fleet mileage.
At the North American International Auto Show, Ford will discuss its "vehicle electrification plan." That will include a family of hybrids, plug-in hybrids, and all-electric, or "battery electric," vehicles scheduled to debut in 2012.
Its first product will be a van-type vehicle for commercial fleets in 2010 and a sedan in 2011 with a goal of making battery-powered cars cost-effective. The cost of batteries make plug-in hybrid or all-electric vehicles significantly more expensive than gasoline engine cars.
Ford said that it will work with unnamed battery and electric-vehicle powertrain providers to bring its electric cars to market.
The company said that it intends to invest $14 billion in efficiency and it will introduce in cars its EcoBoost technology, which it unveiled at last year's North American International Auto Show.
The company also said that it is exploring the sale of its Volvo car division.
