A method of recycling carpet ash may include providing a carpet ash mud including greater than or equal to about 1 % of a feed hydroxide based on the total solids content, adding water to the carpet ash mud to form a diluted stream, and carbonating the diluted stream to form a carbonate. A method of precipitating a carbonate composition may include providing a feed stream including a carpet ash and water, adding a hydroxide to the feed stream, and carbonating the feed stream to produce a precipitated carbonate composition. A method for facilitating precipitation of a carbonate composition may include adding a hydroxide to a carpet ash mud, and carbonating the carpet ash mud and the hydroxide to produce a precipitated carbonate composition. A precipitated carbonate composition may have a brightness less than or equal to about 65. |
