1. A medical waste treatment system (1000), comprising:
a. a main treatment unit (100), said main treatment unit comprising:
i. a waste receiver cover (110); and
ii. a waste shredding unit (120), said waste shredding unit comprising a shredding bin (121) and at least two rotating shredding blades (124);
b. a main liquid/chemical management unit (600) which comprises:
. a water/disinfectant mixing unit (604, 660), and
ii. a first disinfectant delivery unit (605) interconnected to said main treatment unit (100);
c. a separator unit (200) which comprises:
i. a separator arm (202, 1202) comprising a long screw (201), a tray (205) and a mechanical squeezer (1205) at the distal end of said long screw (201), said tray comprising a plurality of orifices characterized by shape and diameter SD2, said shape and diameter SD2 configured to allow the passage of liquids and block passage of solids of a predefined particle shape or diameter; and
ii. an output chute (206); and
d. a plurality of motor units (300) which comprise:
i. a shredding motor unit (301) operatively interconnected to said at least two rotating shredding blades (124);
ii. a mixer motor unit (303) operatively interconnected to said mixing unit (132); and
iii. a separator unit motor;
said first delivery unit (605) comprises a plurality of nozzles through which said disinfectant flows, said first delivery unit (605) being below said waste shredding unit (120);
further wherein at least one of said at least two rotating shredding blades is rotatable at different velocity from at least one other of said at least two rotating shredding blades;
wherein said main treatment unit (100) further comprises a compression unit (122) operatively interconnected to a compressing motor unit (302), said compression unit configured to push said medical waste into said shredder bin (121) towards said at least two shredding blades (124); said shredding bin has convergently shaped side walls configured for conducting a flow of said medical waste onto said at least two shredding blades (124); said compression unit comprises at least two shafts disposed at edges of said shredding bin (121) rotatable by said compressing motor unit (302); said at least two shafts each are provided with a comb secured thereto and formed by a plurality of coplanar arms being arranged in parallel to each other; said at least two shafts are reciprocally rotatable such that said coplanar arms periodically move up and down;
wherein said at least two shafts are configured to enable said medical waste to transfer to said at least two shredding blades (124) when said medical waste is pressed by said at least two combs.
