How Clean Can UV?

“UV radiation affects microorganisms by altering the DNA in the cells and impeding reproduction. UV treatment does not remove organisms from the water, it merely inactivates them.” – Water Research Center

For the longest time this summer I worked on a machine that performed persulfate-ultraviolet oxidation, but I really had no idea what it was. Looking at the machine, I could see that an oxygen tank and a beaker of persulfate solution were combining with my water samples and traveling through various tiny twisted tubes into a swirl of madness that then shot out in all directions and ended up in a scramble of numbers on the computer screen. So I asked around. Ten weeks of “asking around” later, and still all I knew was that somehow the glowing blue light was breaking down the carbon in my water samples and measuring its concentration.

On the left, persulfate-ultraviolet oxidation. Right, SteriPEN technology.

In my last post I mentioned non-profit and for-profit business ventures around the world with a mission to improve society and the environment. It would be naïve to say that the driving force in business is to benefit others. So what is driving entrepreneurs to Africa? An article recently featured in The New Yorker called “The Race to Solar-Power Africa” says it all. Continue reading “Energizing a Continent”

Echoing Green

Echoing Green is a non-profit organization that provides support to entrepreneurs with solutions to social issues worldwide. Once an entrepreneur presents their idea, they are granted 90 thousand dollars to start their business. Financial advisers and other professionals support each business as they take off with their innovations. I chose to cover three such innovations and their creators on the blog today because I find non-profits essential to humanity. Sometimes it gets discouraging to think about how much financial support is needed to start a business. With Echoing Green, those issues are taken care of and inventors are allowed to do what they do best. They are free to create.

When trends die, where do they go? You may be surprised to find that junk can go in more places than just the trash. In fact, there are five possibilities:

  1. Landfill
  2. Combustion – incineration is a popular method used in regions such as Japan but not the U.S.
  3. Recycle – recycling companies melt down certain materials so they can become new products
  4. Reuse – for example, rinsing out your starbucks cup and using it again instead of throwing it out
  5. Re-purpose – for instance, turning a broken sled into a new shelf

Guilty Confessions

Microbeads are banned in some states.

Environmentalists like to act high and mighty sometimes, like earth goddesses destined to restore the ecosystem and punish those who harm it. Labor Day Weekend I was feeling determined. I ran two miles to watch Suicide Squad at the theater, and ran back. How environmentally conscious, right? I know I seem perfect, but I have some confessions to make.

You Can’t

I’ve shared plenty of sweet remembrance on this blog and my memoir “All I See Is Green”. The truth is my journey to getting my degree has been bittersweet. With just a few semesters left I am reminded of student debt, the need for employment, and many other crucial life choices I need to make.  It’s a feeling reminiscent of high school graduation. You can choose to graduate or continue. You can choose to move out or stay home, get married or adventure, just like Game of Life. This post goes out to everyone faced with those decisions right now.
