Sorting system

A waste sorting system for sorting recyclable material comprising:

• a sorting unit including a first sorting station and a first sorting basin containing a first liquid solution of given density to separate the recyclable material into a first material phase that floats in the first sorting basin and a second material phase that is submerged in the first sorting basin of first submersion;
• a wash basin fluidly coupled to an upper portion of the first sorting basin via a first conduit;
• a conveyor coupled to a bottom portion of the first sorting basin for removal of the second material phase;
• and
• a first scraper positioned at the upper portion of the first sorting basin for collecting the first material phase from a free surface of the first liquid solution for transfer of the first material phase to the wash basin via the first conduit, wherein the first scraper is operated by a linear actuator and moves in a back and forth manner along the upper portion;
• wherein the first conduit is angled downward in a direction toward the wash basin to allow the first material phase to flow downhill into the wash basin.
