(e.g. reduction in the costs because of the efficient use of water, energy and residue reduction) Illustrate environmental benefits! (e.g. emission reduction, residual water contaminant charge and toxic substances) Other external benefits! (e.g. improvement in the public image of the enterprise and comply with the standing environmental laws) Promote responsible inquiries !
10 Activity 2: Organize the Team of Cleaner production (1) Team has to be able of identify solution opportunities, develop them and implement them. (Characteristics: knowledge, creativity and authority) Size and integration of the team has to be according to the enterprise organization (5 a 8) Team has to coordinate the Cleaner product- ion activities and the responsibility over the established goals success
11 Activity 2: Organize the Team of Cleaner production (2) Suggested members of the team Management representation. Production Manager Environmental area Motivated Supervisor Motivated Operator or technician External Supervisor or Advisor
12 Activity 2: Organize the Team of Cleaner production (3) To instruct the project team To assure the comprehension of the Cleaner production concept between the members of the team. To reinforce the systematic evaluation importance and records of each process stage that may give an environmental or economical impact. To enable the project team. Create conditions for success (time, information access, etc..). Assure the implementation of the options without any cost and low price. To create incentives (recognitions).
13 Activity 3: Establish Cleaner Pro- duction Goals in the Plant Considerations Goals have to be appropriate and measurable. Have to give significant environmental and/or economical improvement. Short term goals have to be realistic. Long term goals have to be a threat. Indicators Internal productivity standards. Water consumption, energy, generation of residues. Innovative technology.

External costs: Discharge fares, taxes, license costs, etc..
22 Activity 6: Evaluation of Entrances Exits of Materials (3) Operation and maintenance practices: Obvious fails in the process control in the work procedures. Spills and leaks. Obvious lacking in equipment maintenance. Begin to improve order and cleanliness: Obtain the support of the administration to solve obvious problems. Communicate with the workers involved.
