Methods and apparatuses can be configured to facilitate sorting of paper from garbage and/or single stream recycling and subsequently process that separated paper to remove the contaminants from the paper so that the paper is in an acceptable condition for recycling. 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.).

An apparatus for reducing the size of a solid material into smaller particles having an implosion chamber for containing the solid material and creating turbulence and ultrasonic soundwaves. The soundwaves generated by a flail propeller bounce off the chamber walls to create sound frequencies causing the expansion of moisture particles in the solid material leading to implosion of moisture particles within the solid material. The implosion thereby results in reducing the size of solid material, wherein a separating section that receives the smaller material from the implosion chamber channels the coarser particles back into the chamber to go through additional disintegration process. The rotation of the flail propeller within the chamber causes the moisture particles of the solid material to oscillate at high frequency and expansion that disintegrates the solid material. During this process, the moisture content is converted into vapor.

According to a method for fragmenting of pourable material by high-voltage discharges, a material flow of the material, immersed in a process liquid, is guided past an electrode assembly by a conveying device carrying the material flow. By charging the electrode assembly with high-voltage pulses, high-voltage punctures through the material of the material flow are produced. The electrodes of the electrode assembly are immersed in the process liquid from above, and those of these electrodes between which the high-voltage punctures are produced face each other with an electrode spacing transverse to the material flow direction.
