A portable system and method for processing waste to be solidified and placed in an active cell of a landfill. A portable pugmill is moveable adjacent an active cell of a landfill; and portable devices, which may be mounted on sleds or trailers, may be used for feeding the pugmill with waste to be solidified into a landfill-ready state. The waste may be fed to the pugmill without the need for long-term waste storage devices, and avoiding substantial delays between discharge of the waste from trucks to the pugmill-feeding steps.

The present invention relates to a method for removing ink printed on a plastic film comprising various physical/chemical treatments. The main steps in the method are: conditioning the material, grinding, removing ink from the film, washing the film, recovering the cleaning solution, recovering the pigment and drying the film. As a result of the method, it is possible to obtain, on one hand, a plastic film free of ink and, on the other hand, the pigment. Said products may be reused in industry, thereby enhancing the value chain of the product.

A cryogenic grinding apparatus is provided. The apparatus includes a material charge, a low-temperature embrittling device for embrittling the charged ground material by supplying liquid low-temperature gas, a mill for grinding the low-temperature embrittled ground material in an atmosphere containing the low-temperature gas, and a separating device. The separating device has a wind classifier, a removal device to remove the ground material from the mill-output volumetric flow, and a directing device to feed the removed ground material into a classifier-input volumetric flow and to discharge excess mill-output gas of the mill-output volumetric flow. In addition, a cryogenic grinding process is provided in which the ground material is removed from the volumetric flow, excess grinding gas is discharged, removed ground material is feed into a classifier-input volumetric flow of a wind classifier and a classifier-input volumetric flow is classified for separating off a classifier-output volumetric flow containing the fine material.

Apparatus (10) for safe and effective shredding of batteries, including lithium-ion batteries, is disclosed. The system integrates a shredding subassembly (12), an auger/screw conveyor subassembly (14), a rotary screen subassembly (16), and an optional solvent recovery/recirculation subassembly (18). Valves/actuators (26, 28) can be coordinated such that a nitrogen blanket or a vacuum is maintained within the shredding assembly and/or the other subassemblies (16, 18). Shredded battery materials are transported to the rotary screen subassembly (16) via the auger-screw conveyor assembly (14) before being washed and split into solid and liquid sub-components.
