Ineffective removal of grease from restaurants poses a variety of serious environmental problems. Large quantities of grease in public sanitary sewer systems can cause stoppages of piping networks and create costly and time-consuming problems at treatment plants. Sewer backups resulting from grease can also create health hazards when raw sewage backs up into homes or businesses. While grease…
