The disposal of industrial wastes is a problem of increasing importance throughout
the world. Sludge from paper mills are produced in large quantities in most industrial
nations of the world today due to the large usage of paper, constitute one of our
most serious environmental problems. Paper mill sludge has substantially little
usage as a material that can be employed in other industrial applications. Because
of its non-utility, the paper mill sludge is merely discarded, along with other
waste cellulosic fiber, creating a remendous disposal problem. The characteristics
of biosolids are variable and directly related to the technology used to pulp, the
wood and manufacture the paper and to the type of effluent treatment that is employed.The
aim of this work is to investigate and qualify the dried sludge from a recycled
paper mill and the results were compared with the earlier reports and the possibilities
of reutilization for composting / soil amendment were evaluated.
