Non-limiting embodiments of the present disclosure relate to a method comprising: obtaining asphalt shingle waste (ASW) and performing grinding, screening, and separating steps on the ASW. In some embodiments, granules are removed from the ASW. In some embodiments, the method transforms ASW into ASW powder. In some embodiments, the ASW powder is formed into a plurality of briquettes. In some embodiments, at least one of: the ASW powder, the plurality of briquettes, or any combination thereof is fed into a mixing process that results in an ASW powder filled coating.

A bone grinder is provided herein. The bone grinder may have a grinding chamber, an intermediate zone, and a primary cutting element and a secondary cutting element. The intermediate zone may have a first wall and a second wall within the grinding chamber, and the intermediate zone may separate the primary cutting element from the secondary cutting element. The first wall and the second wall may slope inward such that a distance between the first wall and the second wall generally decreases from the primary cutting element to the secondary cutting element. The primary cutting element and the secondary cutting element may be positioned within the grinding chamber to sequentially perform primary cutting operations and secondary cutting operations on a bone. A drive mechanism may operatively engage the primary cutting element and the secondary cutting element.

Provided is a useful improvement in a manufacturing method of a CF-SMC using a partially split continuous carbon fiber bundle. The manufacturing method of an SMC of the present invention includes (i) a step of drawing out a continuous carbon fiber bundle (10) from a package, the continuous carbon fiber bundle (10) having a filament number of NK and partially split into n sub-bundles in advance, (ii) a step of chopping the continuous carbon fiber bundle (10) drawn out from the package with a rotary cutter (234) into chopped carbon fiber bundles (20), and (iii) a step of depositing the chopped carbon fiber bundles (20) on a carrier film (41) traveling below the rotary cutter (234) to form a carbon fiber mat (30). In the manufacturing method, due to a fragmentation processing, in which at least some of the chopped carbon fiber bundles before being deposited on the carrier film (41) are fragmented by being brought into contact with a rotating body, a distribution of the filament number of the chopped carbon fiber bundles in the carbon fiber mat (30) is made different from that when the fragmentation processing is not performed.
