The plastic trash can has been around for a long time, but not the automatic types you can get today. There are many durable plastic models on the market, fitting in any room in the home or office. The automatic model is sensor controlled and has a lid which quickly opens when the trash bag gets about 10 inches and 130 degree angles from the can’s sensor.
