A kitchen waste oil separator, also known as a grease trap or grease interceptor, is a specialized plumbing device designed to intercept most greases and solids before they enter a wastewater disposal system. These systems are critical for commercial kitchens, restaurants, food processing plants, and industrial canteens. By separating fats, oils, and grease (FOG) from wastewater, they prevent sewer blockages, reduce the load on municipal treatment plants, and help businesses comply with environmental regulations. The global market for these separators is expanding rapidly due to stricter environmental laws and the growth of the food service industry.
