In some embodiments, the apparatus and method may utilize at least one dryer device that is configured to heat the paper without combusting the paper to remove water from the paper. The dryer device can also be configured to mix the paper as it is dried while also removing particulate contaminants off of the paper to clean the thrown away paper sufficiently so that the paper is in a condition that is acceptable for recycling into a paper product (e.g. a cardboard box, paper plate, sheets of paper, etc.). ## Claims ### Claim at position 1 1-20. (canceled) ### Claim 21 A garbage processing apparatus comprising: at least one dryer having a chamber configured to receive paper sorted from garbage to heat the paper so a moisture content of the paper is reduced to a level that is at or below a pre-selected threshold; a sensor positioned to measure the moisture content of the paper in the chamber; wherein the chamber of the dryer is sized and configured so that the paper is cleanable as the paper is heated within the chamber; wherein the dryer is also comprised of a grate, the grate having holes in communication with the chamber sized and configured so that hot air is passable into the chamber via the holes for heating and cleaning the paper and dirt that is removed from the paper as the paper is heated in the chamber is also passable through the holes for exiting the chamber of the dryer. ### Claim 22 (depends on 21) The apparatus of claim 21, wherein the apparatus is configured as a garbage processing plant. ### Claim 23 (depends on 21) The apparatus of claim 21, wherein the dryer has at least one moveable shaft connected to the at least one arm. ### Claim 24 (depends on 23) The apparatus of claim 23, wherein the at least one moveable shaft is a rotatable shaft and the at least one arm is a plurality of arms positioned in the chamber to move to agitate the paper in the chamber via rotation of the rotatable shaft. ### Claim 25 (depends on 21) The apparatus of claim 21, wherein the dryer is connected to at least one generator apparatus to receive exhaust gas from the generator apparatus to heat the paper. ### Claim 26 (depends on 21) The apparatus of claim 21, wherein the dryer is configured so that drying of the paper is performed at a temperature that is no greater than 400° F. ### Claim 27 (depends on 26) The apparatus of claim 26, wherein the dryer is configured so that drying of the paper is performed at a temperature that is between 250° F.-400° F. ### Claim 28 (depends on 21) The apparatus of claim 21, wherein the sensor is configured to monitor the moisture content to a pre-selected threshold. ### Claim 29 (depends on 28) The apparatus of claim 28, wherein the pre-selected threshold is 20%, 18%, 15% , 12% or a value between 20% and 12%. ### Claim 30 A method of sorting trash for recycling paper within the trash comprising: separating paper from garbage; and drying the paper separated from the garbage in at least one dryer to heat and clean the paper, each of the at least one dryer having a chamber configured to receive the paper sorted from the garbage to heat the paper to reduce the moisture content of the paper to a level that is at or below the pre-selected threshold, wherein the dryer is comprised of a grate, the grate having holes in communication with the chamber so that hot air is passable into the chamber via the holes for heating the paper and dirt that is removed from the paper as the paper is heated in the chamber is also passable through the holes for exiting the chamber of the dryer. ### Claim 31 (depends on 30) The method of claim 30, wherein the dryer is comprised of at least one arm that is moveable within the chamber of the dryer to agitate the paper as the paper is heated and the dryer is configured to clean the paper as the paper is heated therein. ### Claim 32 (depends on 30) The method of claim 30, comprising: baling the paper after it is dried. ### Claim 33 (depends on 31) The method of claim 31, comprising: passing exhaust from a generator apparatus into the chamber via the holes of the grate to heat the paper while the contaminants are passed out of the chamber via the holes of the grate. ### Claim 34 (depends on 33) The method of claim 33, wherein the pre-selected threshold is 20%, 18%, 15% , 12% or a value between 20% and 12%. ### Claim 35 (depends on 30) The method of claim 30, wherein the drying of the paper also removes contaminants absorbed in the paper. ### Claim 36 (depends on 30) The method of claim 30, comprising: feeding exhaust gas from at least one plant process to the dryer for use in heating the paper for drying and cleaning the paper. ### Claim 37 (depends on 30) The method of claim 30, wherein the at least one arm is a plurality of arms and the dryer has at least one rotatable shaft connected to the plurality of arms that move within the chamber of the dryer for agitating the paper within the chamber while the paper is heated for drying and cleaning the paper. ### Claim 38 (depends on 30) The method of claim 30, wherein the drying of the paper is performed at a temperature that is no greater than 400° F. ### Claim 39 (depends on 38) The method of claim 38, wherein the drying of the paper is performed at a temperature that between 250° F.-400° F. ### Claim 40 A method of sorting trash for recycling paper within the trash comprising: separating paper from garbage; utilizing multiple separators to separate the garbage and paper mixed therein into different flows of garbage having different size ranges such that: a separator separates the garbage and paper mixed therein into a first flow of garbage and paper mixed therein that has a first size range and a second flow of garbage and paper mixed therein that has a second size range that differs from the first size range, a second separator separates the first flow of garbage and paper mixed therein having the first size range into a third flow of garbage and paper mixed therein having a third size range and a fourth flow of garbage and paper mixed therein having a fourth size range that is different from the third size range; processing the third flow of garbage and paper mixed therein to separate paper from the garbage of the third flow for feeding the paper separated from the third flow to a dryer, and processing the fourth flow of garbage and paper mixed therein to separate paper from the garbage of the fourth flow for feeding the paper separated from the fourth flow to the dryer, and feeding the separated paper to the dryer so that the paper separated from the third flow and the paper separated from the fourth flow is fed to the dryer; and drying the paper in the dryer so that a moisture content of the paper is below a pre-selected threshold such that the drying of the paper within a chamber of the dryer removes contaminants adhered to the paper to clean the paper during the drying so that contaminants removed from the paper as the paper is dried in the chamber pass out of the chamber of the dryer in which the paper is dried via holes of a grate that are in communication with the chamber.
