New product intended for use with hazardous materials is packaged in a container that is also capable of being used to ship and dispose of the spent product containing hazardous materials meeting the requirements of UN NA 3085 for Group II Packs for UN DOT Group II hazardous materials and being also capable of being ground up and used for fuel in the manufacture of cement. This method of shipment and novel package is especially useful for shipping filter cartridges intended to be used to filter hazardous materials and to dispose of the spent filter cartridges, producing a novel new product useful as a shipping package and as fuel. Also disclosed is a new filter cartridge that simplifies the new method and package, and the method of making the cartridge.

Package, product and method that facilitates disposal of spent products

A cylindrical polymer fiber filter cartridge for liquid filtration is formed by applying an acrylic latex binder, diluted with water, to a batt of thermoplastic polymer fibers and winding the batt onto a core to form a hollow fibrous cylinder while applying compression with a compression roll to an outer surface of the fibrous cylinder. After the batt is fully wound onto the core, the cylindrical cartridge is rotated at a speed sufficient to cause the acrylic latex binder to foam in-situ thereby fluidizing the cartridge to allow the polymer fibers in the cartridge to reorient to form a smooth outer surface on the cartridge and to evenly distribute the acrylic binder throughout the cartridge. The binder in the cartridge is then cured to bond the fibers together at their points of intersection and annular grooves are cut in the outer surface of the cartridge to increase the surface area of the filter.
