THE POTENTIAL FOR BENEFICIAL REUSE OF SEWAGE-SLUDGE AND COAL COMBUSTION BY-PRODUCTS

Growth in population and industrial production results in increased pr oduction of municipal and industrial wastes. Two waste products are co nsidered here, coal combustion by-products and sewage sludge. Combinat ions of these two waste products have the potential to serve as fertil izer replacements or soil amendments in a wide variety of applications . The potential for utilizing these waste products as soil amendments and fertilizers for agricultural production is considered here. We fin d that, in general, using coal combustion by-products mixed with sewag e sludge can save farmers money by replacing commercial fertilizers.
