Garbage disposals have been around for a while! The first patent for a garbage disposal was granted in 1927 to a man named John W. Hammes. He invented it to help make cleaning up after meals easier and to keep kitchens cleaner. However, it wasn't until the 1930s that they became more popular in households.
So, we can say that garbage disposals have been around for nearly 100 years! They have changed a lot since then, becoming more efficient and quieter. Today, many kitchens have them, helping to reduce the amount of waste that goes to landfills.
