I never would have guessed that the Netherlands would be the origin of a Trash Can that opens its lid automatically when approaching with hands full of trash. But here it is the SensorBin.

From the SensorBin Web-Site:
"No more juggling rubbish in one hand and opening the bin with the other. This handsfree automatic lid opening waste bin uses a patented AI smartchip Sensor-system.
Place hand or debris about 6" away from the IR-sensor near the lid. It will open automatically and will close in 3 - 7 seconds after debris has been released and hand moves away from the sensor. Lid will remain open if hand or debris is within 6" of the ir-sensor. It creates a germ & odor free, automated environment. Free up both hands and feet eliminating the need to push, pull or step."

The SensorBin comes in 24 (99Euros), 32 (109Euros) and 42 (139Euros) liter sizes.
