Every single bean that they roast is Fair Trade Certified, Organic Certified, CarbonFree Certified and Shade Grown, which means the possibility of a real livelihood for coffee growers, a breath of fresh air for the planet, zero net carbon emissions from “crop to cup” and healthy forests for migratory songbirds.

Paul O’Callaghan is CEO of Cleantech consultancy firm, O2 Environmental Inc. and author of Water Technology Markets.

Canadian firm, Saltworks Technologies, just came out of stealth in relation to their desalination technology, which they claim reduce the electrical energy required for desalination by over 70%. They report they can produce 1m3 of water with 1kW hour of electrical energy, compared to the 3.7kWhr per m3, which is what is currently achievable using reverse osmosis with the use of energy recovery devices.

So how to they do it? Well its novel. It appears to be a new approach. And novel and new are two things scarce as hens teeth in relation to desalination technologies.

Back in October, there was quite a bit of controversy surrounding NASA’s project of crashing a LCROSS satellite into the moon to determine if there is in fact water on the moon. While it was initially believed by spectators and researchers alike that the mission was a big failure, since there was no visible lunar dust or any other substances that resulted immediately from the cash; NASA says today that it actually was a success, indicating that the moon has a substantial water supply.

From the comment streams and emails I’ve been getting about recent posts, it is clear that many people believe things that are not actually true about the environmental profile of organic fertilizers.  I don’t mean to minimize the challenge we face when it comes to fertilizers, particularly nitrogen fertilizers.  They take energy to make, have the potential to generate the potent greenhouse gas, nitrous oxide, and can lead to the pollution of ground and surface waters.  With a “rap-sheet” like that I understand why people are concerned, but there is a catch - without fertilizers we don’t eat much.

Still, there is a widespread belief that “Organic” fertilizers are the solution.  I’ve already blogged about why organic fertilizers are dramatically worse from a greenhouse gas point of view.  Today I want to talk about the water pollution issues and why “Organic” fertilizers are actually a much worse problem from that perspective as well.

Why Nitrogen Fertilizers Can Pollute

The reason that ALL nitrogen fertilizers (synthetic and Organic) are a water pollution threat is that they at some point convert to the nitrate ion (NO3-).  That particular form of nitrogen is very water soluble so the nitrate can move down into ground water or sideways into surface water.  The “Dead Zone” or “Hypoxia zone” in the Gulf of Mexico is driven in some large part by nitrate coming from farms.   There are ways to manage this issue, but first I need to talk about the fundemental challenge of crop fertilization.

Veteran solar installer Parkson Corporation is lending its expertise to a new wastewater treatment plant upgrade for the town of Berlin near the Maryland coast.  When it’s finished, the new plant will almost eliminate the use of fossil fuels for drying and converting biosolids, also known as sludge, into a lightweight Class A soil amendment or sustainable fuel.  The process is pushed along by a stainless steel “Electric Mole” that automaticaly mixes, aerates, and granulates the sludge as it dries.

The $16 million upgrade project is funded by ARRA (American Recovery and Reinvestment Act).  Parkson’s Thermo-System Active Solar Sludge Drying Chambers will enable the sludge conversion process to operate under more than 90% solar power rather than using gas or oil.  For disposing sludge in landfills, that translates into a significant savings in preparation and transportation costs.  Even better, it makes sludge products more cost-competitive with conventional soil amendments and fossil fuels, effectively taking the “waste” out of wastewater.

See a battery, pick it up, and all the day you’ll have good luck. Especially if you take the battery that you found and safely recycle it, keeping dangerous toxic poisons out of our seas and drinking water.

I found this used battery near the ocean in Pacifica, right across from our friend Rick’s Salada Beach Cafe. It has since been safely recycled, and kept from polluting our waterways.

Our oceans are already turning into acid. We have to start today to try to make things better. Keeping one more toxic battery or piece of plastic out of our oceans, collectively, will make a difference. Once you start looking, you may be really surprised just how many “disposable” batteries litter our streets and sewers. Next time you see one, pick it up; what you do matters.

The U.S. Department of the Interior reports that overall water consumption in the United States has declined in the past 25 years, even though the population has increased 30% and use by individual American households has increased.  The statistics were compiled by the U.S. Geological Survey.

What’s the secret?  The 25-year patterns of water consumption revealed in the DOI report provide tantalizing clues about the ability of the U.S. to sustain its legendarily consumer-centric lifestyle while stabilizing and ultimately decreasing its contribution to carbon emissions and other greenhouse gasses.

An ecologist and an engineer at Michigan State University are working together to create robot fish that can better monitor various factors in aquatic environments.

Combining the brilliance of nature with some top-notch engineering, these two scientists are on to something and getting the funding for it.

The researchers are breaking ground with this and looking to raise water monitoring to another level.

Pollution from industrial facilities like this one at East Harbor in Indiana up to the 1970s left a legacy of contamination still in need of cleanup from new Great Lakes restoration funding.

Giving President Obama a major victory, Congress on Thursday sent him a spending bill containing $475 million in new funding to help restore the Great Lakes. During his 2008 campaign, candidate Obama committed to a multi-year effort to combat Great Lakes invasive species, habitat loss, climate change impacts and threats to water quality. The Great Lakes contain almost one-fifth of the world’s available surface freshwater.

Sigourney Weaver narrates “Acid Test“, an illuminating and terrifying NRDC documentary that explains how quickly our planet’s oceans are acidifying due to all of the carbon dioxide that we are pumping into our air. This pollution is causing rapid changes in our oceans’ chemistry that will completely disrupt all life on the planet as we know it on a scale that has not been seen for tens of millions of years.

Solar water disinfection is an idea so simple, it hurts.  Now a Georgia Tech scientist may be on to a new high-tech twist that could make this no-cost, zero emission ultraviolet (UV) water disinfection method even more quick and effective.

Solar disinfection is a proven method of killing germs in drinking water by exposing it to direct sunlight in a clear plastic or glass bottle.  Dr. Jaehong Kim of the Georgia Institute of Technology has just been awarded a $100,000 innovation grant by the Water Environment Research Foundation for his work in developing a new coating that could be applied to bottles to shorten the solar disinfection process and improve its effectiveness.  Though not (yet) practical for large volumes of water, solar disinfection has proven to be a sustainable answer for people in remote locations or impoverished areas that lack the resources to disinfect their drinking water through other means.
