The method comprises forming a mixture of non-wood fibers and exposing the mixture to a brightening agent, the brightening agent being a permanganate compound, an acid, or a combination of the permanganate compound and the acid. The resulting brightened fibers have a brightness greater than the fibers of the mixture before exposure as measured by MacBeth UV-C standard.
