Pollution Prevention Program

A pollution prevention or waste minimization program usually consists of the following [79]:

• conducting a waste survey;

• screening waste streams for minimization opportunities;

• developing minimization options;

• screening minimization options;

• evaluating high-priority options;

• scheduling and implementing desirable options;

• evaluating and reviewing program performance periodically.

For a waste minimization program to succeed, refinery managers must provide the necessary staff and other resources to accomplish their goals. A team committed to the tasks is usually assembled. Because a refinery is a complex facility and there are numerous emission sources and waste streams to take into account, the team should consider and give the highest priority to:

• Pollution prevention hierarchy—The order of preference (highest to lowest) is source reduction, recycling, treatment, and secure land disposal;

• Reduction of waste volume—Volume reduction will usually reduce cost for handling, treatment, and disposal;

• Ease of implementation;

• Proven performance;

• Safety and health risks to employees and the public.

Some waste minimization approaches are proving to be more successful than others. Studying several refineries for waste minimization opportunities led to these eye-opening conclusions [79]:

• Housekeeping is the most cost-effective way to minimize waste;

• Solids that enter the refinery's wastewater treatment system automatically are classified as hazardous waste. Therefore, refiners can lower the volume of hazardous waste generated by keeping nonhazardous waste out of the treatment system;

• Raw materials (e.g., crude source) substitution is difficult because the choice of material is dictated by economics, availability, and the process units at the refinery;

• Process modifications can be implemented but may require considerable research and development;

• In-plant and offsite reuse of wastes plays a major role in waste minimization.
