We aren’t big fans of reports and surveys, but this one is an eyeopener. After all the go green buzz that we hear about, according to a report by ABI research only 2% of unused cellphones are actually recycled.
Some more facts of the research:
- currently only 6% of used mobiles are refurbished
- only 8% mobiles are disposed properly
- in 5 years 18% of mobile would be either refurbished or recycled
Various companies have (more…)

We love surveys and research. And here comes another one that makes me feel like a deadly polluting criminal. Though the research isn’t particularly targeted to Google, it cites example of the serach engine and thus it naturally gets loads of attention. The study made by Harvard Researcher Alex Wissner-Gross highlights the CO2 emission due to usage of computing power while on the internet. Acording to the report basic browsing on the internet can result in CO2 emission ranging from 0.002g to 0.2g; while a typical Google search can release upto 7gms of CO2 owing to the processes involved.
Google has been quick to respond on its blog with its own figures. “…Google search uses just about the same amount of energy that your body burns in ten seconds … In terms of greenhouse gases, one Google search is equivalent to about 0.2 grams of CO2.”

Space Junk:
Thousands of nuts, bolts, gloves and other junk debris from space missions form an orbiting garbage dump around Earth, presenting a hazard tospacecraft. Some of the bits and pieces scream along at 17,500 mph. Space Junk is also known as Space debris or orbital debris. These junk materials eventually fall back in to the atmosphere just like any other meteor, lighting up the sky.
Space Debris is becoming a matter of growing concern, collision with flights and functioning satellites can be highly damaging. On July 23, controllers in Houston raised the orbit of the International Space Station by roughly five miles to avoid hitting a half-ton tank of ammonia that a spacewalking astronaut had tossed out earlier in the day while doing some housecleaning on the $100 billion outpost.
“We don’t normally dump something like this,” said Lynette Madison, a spokeswoman at the Johnson Space Center. But, she added, the spaceshuttle had no room in its schedule for returning the refrigerator-size tank to Earth. Officials expect the container to orbit the Earth for nearly a year before making a fiery re-entry.
On Feb. 2, a new Chinese navigation satellite suffered an apparent engine failure that left it in dozens and perhaps hundreds of pieces.On Feb. 14, an abandoned Russian engine broke into roughly 60detectable pieces, apparently because residual fuel had exploded.
On Feb. 18, a retired spacecraft jointly developed by China and Brazil suddenly and mysteriously broke into dozens of pieces. American experts suspect it was the victim of a collision with other space debris.
Then on Feb. 19, a large Russian space tug exploded, apparently from residual fuel, creating a cloud of about 1,000 pieces of detectable debris.
Orbital Debris Quarterly News, a NASA publication, noted that at least three of the four breakups appeared to have been preventable if more caution had been exercised in designing and operating the vehicles. The NASA Orbital Debris Program Office is located at the Johnson Space Center and is the lead NASA center for orbital debris research. It is recognized world-wide for its leadership in addressing orbital debris issues.
