Abstract
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.
