Dry abrasive blasting is a surface preparation process used in shipyards for cleaning the surfaces of the metal plates to be used in various components of the ship. Commonly used abrasives include sand, steel grit, mineral abrasives, metallic abrasives, and synthetic abrasives. The basic objective of this study was to understand the environmental performance of two abrasives, Steel Grit and Specialty Sand. The project was funded by the Gulf Coast Region Maritime technology Center (GCRMTC) and USEPA. It simulated actual blasting operations conducted at shipyards under enclosed, controlled conditions on plates similar to steel plates commonly blasted at shipyards. The emissions were measured using EPA Source Test Method to quantify particulate emissions. Steel Grit was observed to be more productive, less consuming, and more environmentally friendly compared to Specialty Sand. The findings obtained in this study will be valuable in reducing costs, improving productivity, and protecting the environment.
