Abstract
Devices and methods are disclosed for processing waste paper media and other waste fibrous products to reduce their volume. The methods include disintegration and compression, in some embodiments transforming the waste into a highly dense, combustible solid, for example a cylinder which may be burnt as a log or readily stored or transported.
Claims21
A device comprising:
- a shredder configured to cut waste fibrous media,
- a disintegrator configured to further process the cut waste fibrous media, mixing it with a liquid to form a paste, and
- a compression unit configured to extract excess liquid from the paste and form the paste into a compressed solid.
A device comprising:
- a disintegration unit which utilizes an aqueous environment to render waste fibrous media into a paste, and
- a compression unit positioned to receive the paste from the disintegration device and compress the paste.
A method comprising:
- shredding waste fibrous media,
- disintegrating the shredded waste fibrous media while mixing it with liquid to form a paste, and
- compressing the paste to extract excess liquid from the paste and form the paste into a compressed solid.
A method comprising:
- mechanically treating waste fibrous media in a dry environment;
- further processing the treated waste fibrous media in an aqueous environment, rendering the waste fibrous media into a moist fibrous paste;
- and
- mechanically compressing the fibrous paste to extract excess liquid from the paste, resulting in a compressed solid.
