The next step is to develop conceptual strategies that specifically match the causes of emissions and waste generation. Addressing the fundamental causes helps to develop long-term solutions rather than simply addressing the symptoms.
A simple tool for brainstorming ideas and developing options is to use checklists based on practical experience. Tables 3.3.1 to 3.3.4 list 100 pollution prevention strategies based on changes in engineering design, process chemistry, operating procedures, and maintenance practices. These tables are based on the experiences of Chadha (1994), Chadha and Parmele (1993), Freeman (1989), Nelson (1989), and the U.S. EPA (1992) and are not comprehensive. The variety of technical areas covered by these checklists emphasizes the importance of a multimedia, multidisciplinary approach to pollution prevention.
