> It is better to prevent waste than to treat or clean up waste after it has been created. It is better in this experiment to clean up waste after it has been created in this experiment > Synthetic methods should be designed to maximize the incorporation of all materials used in the process into the final product. Atom economy is considered to be close to 100% and that is consider very desirable > Wherever practicable, synthetic methods should be designed to use and generate substances that possess little or no toxicity to human health and the environment. No this experiments uses chemicals to extract yeast molecues that are consider harmful to humans and flammable > Chemical products should be designed to effect their desired function while minimizing their toxicity. The only toxicity from this experiment is the Sodium borohydride and it is consider flammable > The use of auxiliary substances (e.g., solvents, separation agents, etc.) should be made unnecessary wherever possible and innocuous when used. Yes but the solvents used to have waste materials that are being created in part 8 of this experiment > Energy requirements of chemical processes should be recognized for their environmental and economic impacts and should be minimized. If possible, synthetic methods should be conducted at ambient temperature and pressure. The energy required for this experiment is used to ferment the yeast and to extract the compounds from heated sugars so it has little energy and economic costs to be considered > A raw material or feedstock should be renewable rather than depleting whenever technically and economically practicable. Bakers yeast is a renewable resource so it is consider a good feedstock > Unnecessary derivatization (use of blocking groups, protection/ deprotection, temporary modification of physical/chemical processes) should be minimized or avoided if possible, because such steps require additional reagents and can generate waste. This experiment only generates waste from water that must be properly dipposed of from the NaBH4 > Catalytic reagents (as selective as possible) are superior to stoichiometric reagents. No catalysis was used for this experiment > Chemical products should be designed so that at the end of their function they break down into innocuous degradation products and do not persist in the environment. Little enviormental effects in this lab considering the natural effects of bakers yeast and the fermentation process > Analytical methodologies need to be further developed to allow for real-time, in-process monitoring and control prior to the formation of hazardous substances. This lab experiment has 3 four hour session to let the yeast ferment to be extracted > Substances and the form of a substance used in a chemical process should be chosen to minimize the potential for chemical accidents, including releases, explosions, and fires. > Water is used in this experiment as well but NaBH4 for is considered flammable and should be handled with care and away from open flames

What happened here? This is identical to the other one you wrote, and seems to refer to the other experiment. Whoops!
