Section Five WASTE MANAGEMENT B. SLUDGE MANAGEMENT 58 BY-PRODUCT RECOVERY OF TANNERY SOLID WASTES AS AN ALTERNATIVE TO SANITARY LANDFILLING Tzu-Yar Liu, Graduate Assistant Raymond W. Regan, Sr., Associate Professor Department of Civil Engineering The Pennsylvania State University University Park, Pennsylvania 16802 INTRODUCTION The continuing search for improved solid waste management procedures by industry has been in response to Federal and State environmental legislation. As noted by Pardus and Regan,' the ultimate goal for industry has also been the development and application of a comprehensive waste management strategy that maintains or improves product quality while reducing costs. The subject of the presentation concerns a research effort seeking to achieve this ideal at a small tannery using traditional processes for the production of fine leather from raw hides (Howes Leather Company, Curwensville, PA). The primary source of the information presented is after Liu.2 The results indicate preliminary findings for an ongoing effort. STATEMENT OF PROBLEM As a general requirement of Pennsylvania's environmental legislation, each industry has had to characterize solid wastes for the Pennsylvania Department of Environmental Resources (PaDER, module one) and implement procedures for the alternative handling of solid wastes presently being disposed by sanitary landfilling. In 1989 Pennsylvania Act 55 provided industries with an approval mechanism for the beneficial recovery and reuse of industrial solid materials. The Howes Leather Co. has identified three major types of their solid waste to be considered as candidates for by-product recovery and new products; namely, fleshings, leather dust, and wastewater sludge. The approximate composition of solid wastes from Howes Leather Co. is given in Table I. Table I. Approximate Composition of Process By-Products from Howes Leather Co. Solid Wastes tons/week percent Leather dust (94.1% solids) 0.4 0.32 Tannery sludge (36.6% solids) 115 91.7 Fleshings (17.9% solids) 10.0 8.0 Total 125.4 100 Note: Fleshings are the sum of lime fleshings, short summer hair, lime trimmings, and leather fleshings. 47th Purdue Industrial Waste Conference Proceedings, 1992 Lewis Publishers, Inc., Chelsea, Michigan 48118.
