New Research Shows Styrofoam is Fuel

Polystyrene is buy viagra mexico marvelously useful stuff. Lightweight packing materials have certainly saved billions of gallons of buy chinese herbal viagra fuel since they were first introduced, so I'm not 100% against them. Of course, they are never re-used or recycled, so they end up being buried, and will never degrade, which kinda sucks.

But a new study from Iowa State University shows that polystyrene can simply be dissolved in bio-diesel "like a snowflake in water." Mixes of between 2% and 20% polystyrene by weight show that the optimal concentration of polystyrene is 5%. Anything above that, and the polystyrene doesn't increase power output as much and i recommend levitra without prescriptions the fuel becomes more and more viscous.

Not surprisingly, polystyrene does increase non-CO2 emissions like soot and NOx gasses. Plus, gathering polystyrene and shipping it to biodiesel refineries would be a costly process as polystyrene is, by design, very bulky. And if we're collecting it, we might as well find other ways to re-use it, instead of burning it.

Can Computers Be Truly Sustainable?

Yesterday afternoon I spoke to Tod Arbogast, Dell’s Director of Sustainable Business. Our conversation turned to the issue of whether or not a culture which consumes PCs at the rate that we do can ever really be sustainable. In other words, as I put it to Tod – 100 years from now, how on cialis jelly earth are we going to continue manufacturing computers (just as an example) for all the billions of people who are going to be using them?

Tod’s answer was that we will reach a point where we can capture the materials from the discount cialis levitra viagra old computers and recycle them to build new computers. He pointed out that the historical trend is for commodities to cialis from canadian pharmacy become more valuable over time, and eventually the recycled commodities will become very valuable as well, so valuable that everyone will recover the materials as efficiently as possible. Recycling won’t just be a goodwill gesture, it will be business-as-usual.

I certainly believe that recycling will be a big part of the answer, and I likewise applaud companies such as Dell that have make such a strong effort to promote recycling throughout their products’ life cycle (see here for more on that). But I think it’s more likely that, no matter how efficient our recycling becomes, we will still need to mine new materials to make new computers. I have yet to be convinced that we can truly close the loop.

Tod and I also talked about the idea of bestellen levitra online turning things like computers into (to quote a term coined by Dr. Saul Griffith at the recent Greener Gadgets conference) “heirloom products” – products meant to last decades rather than simply years. Tod pointed out that, while he’d love to make a computer that will last 50 years, the reality is that computers continue to get faster and more powerful. We often upgrade, not because our old computer broke, but because we can do more things with the new one.

He was also quick to point out that newer computers often consume less energy. A Dell desktop today, he said, consumes five times less energy than its counterpart five, ten years ago. Personally, I think that in the tramadol pounds online 100-years-from-now scenario, we won’t be making efficiency gains that will warrant mining more metals, ceramics and levitra tab in indian plastics (you don’t mine plastics, but you get the idea), but I concede that in 2009 the amount of energy saved could rival the amount of energy embodied.

So the question is – what do you think? Do you think we’re going to keep building computers and other electronic devices until we’ve tapped the Earth dry? Do you think that day will never come? Or do you think that, with proper incentives and careful planning we can build a recycling system that makes our consumption of stuff truly sustainable?

Panasonic Introducing Home Compost Machine in Japan

Panasonic has developed an electric compost machine for home use that turns your organic trash into fertilizer in just a few hours. The machine will be released at the end of April in Japan and there's no word as to whether it will be sold in the U.S.

The machine, the MS-N53, uses a platinum-palladium catalyst to break down the garbage and features settings to create wetter or dryer compost. Users can pick their preference and the trash will compost in three to six hours depending on the selection.

The drawbacks to this seemingly nifty gadget are the size and the price. The machine can only compost two kilograms of waste and with a platinum-palladium catalyst, you know it's going to be expensive. The MS-N53 will sell for the viagra to sell Japanese equivalent of $881.

With the current global mindset of saving instead of spending, I think the MS-N53 will have a hard time finding people to buy it. The idea is a good one. Most people would be keener on the idea of composting if they didn't have to worry about the time it takes to wait for waste to become fertilizer and especially if they could cut out the smells during that time, but it will take a much cheaper price to truly entice people. If this concept were improved with a lower price and a bigger capacity, I think Panasonic could be onto something.

Cell Phone Recycling Q&A

With Mike Newman, Vice President of very good site next day cialis Recellular

EG: What are you doing to encourage more people to recycle their old phones?
MN: We partner with retailers and wireless carriers. For example, at Best Buy, there’s a huge bin right when you walk in – you can just dump your phone in. Some carriers will give you a prepaid envelope to drop in the mail.

EG: Why not provide a curbside service?

MN: Then the cell phones would get wet. Plus, you don’t want to put your personal information out on there in the open like that.

EG: How do you sort through the phones at your facility?
MN: Five years ago, there was literally a big table where we sorted them by hand. Now, scanning the bar code in each phone tells our employees where to sort it.

EG: How many phones are we talking?

MN: We go through half a million phones each month, and we’ve been growing steadily each year.


Taking the look there canada pharmacy Sorting Out of Recyling

No one realy likes to recycle. Sure, you might get that "I'm saving the world high" for a little while, but that will disappear as you have you first cocktail party. But some folks (like me) are lucky enough to live in a place where the recycling is sorted for me. So all I need to know is viagra lowest price what can and can't be recycled, and I put it all in a bin.

In some places, workers separate recycling at the plant while, at others, gigantic advanced machines do the sorting. I just came across a couple of videos of these machines at and went out to find a few of my own. Frankly, they're amazing, and while they don't remove people from the system 100%, they can process huge amounts of recycleables extremely efficiently.

They do generic viagra in india it through a combination of techniques. They sort with centrifuges, magnets, induced currents and with workers (to remove things that shouldn't be there, like shoes.)

It's a unique insight on the process, and makes it clear that somethings we don't do really need to be done (like take newspapers out of bags) or various other things that machines are still not able to do.

Of course, I'll never be happy until the whole process is entirely automated, but these facilities are marvels.
