discuss pollution prevention in the dry cleaning and hydraulic fracturing industries.

Unit V discusses pollution prevention in the dry cleaning and hydraulic fracturing industries. Please discuss any experiences you have had with these industries, especially those related to pollution prevention. Feel free to discuss some of the readings for this week and your thoughts about using liquid carbon dioxide as a substitute for toxic chemicals in the dry cleaning and/or hydraulic fracturing industries. As an alternative, pick an industry in which you are familiar with that utilizes solvent cleaning, painting, metal surface prep, machining, or other processes, and discuss your experiences with specific P2 activities (but not related to those industries identified in unit IV)
