(a) One company replaced the organic solvent, trichloroethane with a water-based solvent. How is this P2 ? (b) Consider another company that used trichloroethane to clean metals, but used it only one time and then discarded it. The company discovered that it could reuse trichloroethane several times before it becomes too dirty to perform effectively. Could this reuse also be considered P2 ? Explain.
