Challenges: Connecting principles of green chemistry & sustainability with the currently applied industrial processes

Challenges: Connecting principles of green chemistry & sustainability with the currently applied industrial processes brings two main challenges: n To provide access to the newest developments in the industrial fields n To align both the teaching content and the teaching strategies with the continuing updating requirements imposed by economic and environmental factors

Solutions to the challenges n n Move away from traditional topics toward real-life cases.

Solutions to the challenges n n Move away from traditional topics toward real-life cases. Change the design and methodology to fit this new approach. Initiate and develop partnership with local area businesses interested in ‘greening' their production/operation while providing real-life cases for study. Use the practical cases as an ideal ground for challenging the students' ability to analyze and understand the existing problems and to develop their critical thinking, while finding creative solutions.

Web-based companies analysis n The two companies I compared are ITW DEVCON FUTURA & DSM NEORESINS INC. The former is a custom compound purchased resins company located in my hometown of Oxford, Michigan, while the latter is involved with plastics, materials and resins located in my former home of Frankfort, Indiana. ITW DEVCON FUTURA has no on-site releases, 223 off-site releases and 7711 total transfers for further waste treatment. DSM NEORESINS INC has 1229 on-site releases, 196 off-site releases, and a total waste managed of 23894. ITW's most significant wastes were diisocyanates and lead compounds, but DSM's significant wastes were much more varied. DSM lists 1, 2, 4 -trimethylbenzene, acrylic acid, acrylonitrile, butyl acrylate, glycol ethers, ethyl acrylate, methyl methacrylate, propyleneimine, and styrene. n What is clear from these examples, is that resins cannot be categorized as one thing and wastes from one type of resin might be very different from another. I wonder if their products can be used interchangeably or if Indiana and Michigan have different regulations for toxic release. B. K. , student, GVSU n

I have an idea… an Osmosis Tower Idea: eliminate the energy needed to pump

I have an idea… an Osmosis Tower Idea: eliminate the energy needed to pump water up to the top of water towers and purify the water at the same time by use of solute pumping and distillation by the suns rays. Principle behind the solute pump: osmosis. Each level would have an increasing concentration of salt. The water would be pumped to the top and at the top, the heat of the sun, focused by lens, causing the water to distill. This would increase the concentration and cause a chain reaction of more water being pumped up. The pure H 2 O could be collected for distribution

Feddeler Landfill, Lowell, Indiana n Nobody ever expected Feddeler Construction/Demolition Landfill to be such

Feddeler Landfill, Lowell, Indiana n Nobody ever expected Feddeler Construction/Demolition Landfill to be such a hazard to the town of Lowell, Indiana. Sure, landfills are dirty and smelly, but small town residents usually trust that the owner of such a landfill would follow state regulations to keep the town safe. That’s a very wrong assumption to make in this particular case. n From 1971 to 2003, the 40 acre Feddeler Landfill took in construction material, demolition waste and buried at least 500 barrels of toxic acrylonitrile underground. However, the conspiracy is not a new one. Dumps built since the 1970 s have natural or synthetic “liners” at the bottom to prevent seepage, but it is assumed that the founder, Robert Feddeler, had been taking waste into the dump since the 1950 s.

Green Chemistry Article Assignment n my search of the web site for www. chemistry.

Green Chemistry Article Assignment n my search of the web site for www. chemistry. org turned up 20, 800 results for the query “green chemistry. ” For www. google. com, I found 32, 000 results, and at www. googlescholar. com, 1, 170, 000. n Compare this to my search of: www. cbs. com: 91 results, many not specific for green chemistry, or, not even about the subject (some were advertisements). Similar results were obtained at www. nbc. com, www. abc. com. and www. nyt. com (the New York Times). n What this seems to indicate is a lack of dissemination of information on green chemistry beyond the confines of professionals and students who work in the field of chemistry.

Green Chemistry Article- Assignment n Green chemistry is going to create a paradigm shift

Green Chemistry Article- Assignment n Green chemistry is going to create a paradigm shift in the way products are manufactured. It is such a change from “business as usual” that amazing stories about it should be on the TV and in newspapers every week. However, given the fascination our populace has for the sensational, the lurid and the trivial, I am not surprised that the news outlets don’t run stories much more often. Part of the problem is definitely how to package the story to make it exciting, maybe with a little touch of science fiction. A good science writer could provide that element. In any case, most of the public, judging by the paucity of results found at the news outlet web sites, have never heard of green chemistry.

n n n Most of the public, judging by the paucity of results found

n n n Most of the public, judging by the paucity of results found at the news outlet web sites, have never heard of green chemistry. They are not likely to anytime soon. This is sad, because most stories about accelerating environmental problems paint a scenario that counsels despair. Green chemistry shows that we humans have a powerful tool that we can employ to reduce pollution, re-use materials, and greatly reduce the amount of toxic materials entering the biosphere. Green chemistry fosters hope that the human intellect and capacity for ingenuity can, combined with the political will, snatch our planet away from the brink of the abyss. And the need for the political will to exert itself is why the public needs to hear about green chemistry! They are the political will.

Dear Editor: A wonderful tool has been unraveled in just the last 15 years

Dear Editor: A wonderful tool has been unraveled in just the last 15 years that allows the chemical industry to revolutionize the manufacture of all the products we have come to expect as part of everyday life. It is called “green chemistry. ” It consists of replacing one manufacturing process which uses too many starting materials and creates a lot of sometimes toxic unusable waste with a new process. This new process utilizes smaller amounts of non-toxic (or less toxic) starting materials, requires less fossil fuel and produces little to no waste, and, usually, no toxic by-products. Hence the designation “green chemistry” to indicate that it is friendly to the environment. Green chemistry is still in the early stages of replacing the old paradigm of manufacturing. That was based partly on something we used to believe: that we will never run out of anything. Now we know we can. So we must begin to prepare for a time of scarcity. The ingenuity of green chemistry is in the ability of chemists to find substitute methods that greatly reduce waste and toxics. This staves off scarcity, buying us time to create an alteration in lifestyle expectations, which will surely have to occur as the world population continues its upward trajectory. The replacement of old manufacturing methods with those of green chemistry should give hope to the public that we needn’t give up all comforts and conveniences in order to “save” the planet. Human creativity and intellectual prowess, coupled with political will, has gotten us through in the past. It should suffice in the future.
