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. 127-. (canceled)28. A method comprising: asphalt,', 'limestone powder,', 'granules, and', 'impurities;, 'wherein the ASW comprises, 'obtaining asphalt shingle waste (ASW);'} 5 wt % to 40 wt % asphalt based on a total weight of the ASW powder,', '60 wt % to 95 wt % limestone powder, granules, and impurities based on the total weight of the ASW powder., 'wherein the ASW powder has an average particle size of 2 microns to 425 microns, and wherein the ASW powder comprises, 'performing sufficient grinding steps and screening steps on the ASW to result in ASW powder;'}29. The method of claim 28 , wherein the sufficient grinding and screening steps comprise:grinding the ASW to form ground ASW; andscreening the ground ASW.30. The method of claim 29 , wherein the screening of the ground ASW results in: 'wherein the first set of ASW particles has an average particle size of 425 microns to 6350 microns, and', 'a first set of ASW particles,'} 'wherein the second set of ASW particles comprises the ASW powder having the particle size of 2 microns to 425 microns.', 'a second set of ASW particles,'}31. The method of claim 29 , wherein the step of grinding the ASW to form ground ASW comprises a first grinding step and a second grinding step claim 29 ,wherein the first grinding step is the step of grinding the ASW to form ground ASW; 'wherein grinding the first set of ASW particles results in a third set of ASW particles, ...
