A green chemistry candidate school was selected in each locality to feature as a case study in this project. As part of this case study, NYSDEC reviewed each localities' green chemistry candidate school's chemical inventory with the aim of reducing, at the source, hazardous and high risk chemicals used and stored by high school laboratories.
The data generated from the school's chemical inventory served as a baseline foundation to measure changes resulting from replacement of traditional chemistry by green chemistry practices. In addition, by providing green chemistry training to New York State's science teachers, NYSDEC will have taught the teachers to consider the life cycle of the chemicals they work with at the school laboratories, from purchasing to disposal, and how it can affect their health, potential liabilities, the impact on the environment and the costs associate with waste disposal.
Please email us at pollutionprevention dec. The first step for schools is to begin properly managing their chemical inventory. DEC can offer assistance to schools in chemical management.

Design less hazardous chemical syntheses : Design syntheses to use and generate substances with little or no toxicity to either humans or the environment.
Design safer chemicals and products : Design chemical products that are fully effective yet have little or no toxicity. Use safer solvents and reaction conditions : Avoid using solvents, separation agents, or other auxiliary chemicals. If you must use these chemicals, use safer ones. Increase energy efficiency : Run chemical reactions at room temperature and pressure whenever possible.
While the plant poses a potential environmental risk, that risk is mitigated by limiting the exposure: chemicals are contained in tanks, which are monitored; second containment is in place; operating equipment is regularly checked by qualified technicians; special personnel is trained to deal with leaks. Navigation menu. Good insulation and well-maintained equipment will reduce heat loss, and any waste heat can be used for warming offices and producing hot water rather than being lost to the atmosphere. Solvents, which are used to dissolve other substances into a solution during the production of chemicals, should be of minimal toxicity. Download Citation: Green Chem. The Green chemistry approach, in contrast with traditional practice, targets risk reduction through reduction of hazard. The catalyst can be readily regenerated.
Use renewable feedstocks : Use starting materials also known as feedstocks that are renewable rather than depletable. The source of renewable feedstocks is often agricultural products or the wastes of other processes; the source of depletable feedstocks is often fossil fuels petroleum, natural gas, or coal or mining operations.
Avoid chemical derivatives : Avoid using blocking or protecting groups or any temporary modifications if possible. Derivatives use additional reagents and generate waste. Use catalysts, not stoichiometric reagents : Minimize waste by using catalytic reactions. Catalysts are effective in small amounts and can carry out a single reaction many times. They are preferable to stoichiometric reagents, which are used in excess and carry out a reaction only once.
Design chemicals and products to degrade after use : Design chemical products to break down to innocuous substances after use so that they do not accumulate in the environment. Analyze in real time to prevent pollution : Include in-process, real-time monitoring and control during syntheses to minimize or eliminate the formation of byproducts.
