Waste King, USA.

Waste King is an American company that specializes in the manufacture of food waste disposers.

Choppers are designed to crush waste generated during food preparation or dishwashing.
The company produces both industrial waste disposal units and semi-professional ones for use at home if necessary.
The product is a device that fits into the kitchen sink in place of the standard siphon and connects to the sewer system via a special drain hole. This device operates using a "grater" system—a rotating disc grinds waste. There are no knives or blades involved.
The disposal system is designed for any type of food waste (meat, fish, small bones, fruits, cereals, etc.).
Not only are waste disposal units completely safe for the septic tank, but they are also beneficial in that they prevent any clogging or blockage of pipes with waste.
