The principal objective of this project is to define the requirements and procedures necessary to implement an effective shipyard solvent reclamation program. Most large shipyards can easily cost justify the purchase of an on-site recycling system. However, difficulties often arise with setting up and maintaining a comprehensive program for the use of equipment and reclaimed solvents. While this report emphasizes program implementation, economics are discussed to an extent necessary to assist a shipyard that has not yet purchased a solvent reclamation system. Although several methods exist for small-scale reclamation of solvent waste, the scope of this project has been limited to the distillation process, since this is the most commonly used method. For completeness, other recycling techniques are briefly described. Also, to best serve the intended audience, the project focuses on solvents used in painting operations. The report begins with a summary discussion of the economic and environmental benefits of solvent recycling, along with alternatives to recycling. Since the environmental and regulatory aspects of solvent use and solvent recycling are becoming more important each year, a full section of the report is dedicated to these issues. Survey data from shipyard and industry users of recycling equipment and equipment manufacturers is also included. |
