A method of recycling carpet components, said method comprising:
- separating at least a portion of fibers from a first mixture of carpet components comprising carpet fibers, a carpet adhesive component, and used filler material so as to form a second mixture comprising residual carpet fibers, the carpet adhesive component, and the used filler material;
- and
- co-grinding the second mixture with a solid inorganic particulate material, wherein said co-grinding step results in a third mixture comprising a free-flowing powder having an average particle size.
A free-flowing powder comprising:
- particles of recycled carpet material, said recycled carpet material comprising residual carpet fibers or carpet fiber portions, a carpet adhesive component, and used filler material;
- and
- solid inorganic particulate material, said solid inorganic particulate material being from a source other than recycled carpet material;
- wherein said free-flowing powder has an average particle size ranging from about 1.0 to about 50 microns (μm).
