What is the purpose of a grease trap?

The purpose of a grease trap is to prevent grease buildup in drains and public systems. Grease traps are essential in commercial kitchens and food establishments where large quantities of fats, oils, and grease (FOG) are produced during cooking processes. These substances can solidify and accumulate in plumbing systems, leading to clogs, backups, and even more serious issues like sewer blockages.

By capturing and retaining these materials before they enter the wastewater system, grease traps help protect drainage infrastructure, reduce maintenance costs, and comply with local regulations regarding waste disposal. This proactive approach not only preserves the plumbing but also minimizes environmental impact by preventing the release of grease into public sewage systems, which can lead to water pollution and other environmental concerns.

The other choices provide different functions that are not the primary purpose of a grease trap, such as storing cooking oil, which would typically require separate containers for safe disposal or recycling, and not specifically addressing the issue of grease in drainage.
