Anaerobic Digestion of Tomato and Pumpkin Wastes R. A. Canham Sanitary Engineer, National Canners Association Washington, D. C. Don E. Bloodgood Professor of Sanitary Engineering, Purdue University Lafayette, Indiana Tomato Waste Experimental work on anaerobic digestion of food-canning wastes was carried on in the Sanitary Engineering laboratory at Purdue University during 1947, following a preliminary survey and investigation in 1946, and was reported by O. H. Hert in "Tomato and Pumpkin Wastes," "Proceedings of the Third Industrial Waste Conference, 1947," Engineering Bulletin of Purdue University, Extension Series 64, 1947, page 244. Other work on industrial waste predigestion has been reported by Frederick G. Nelson, "Predigestion of Industrial Wastes," California Sewage Works Journal, Vol. 17, No. 1, p. 27 (1945). Results of the laboratory experiments on food-canning wastes in the Purdue laboratory were such that it was deemed advisable to continue the work on a larger scale. It was decided to conduct the digestion experiments on tomato and pumpkin wastes. The site of Ladoga, Indiana, was selected for several reasons. Ladoga is a city of approximately 1,000 people, with the Ladoga Canning Company operating a canning plant normally packing tomatoes and pumpkin. The city operates a trickling- filter sewage-treatment plant, handling combined domestic sewage and the canning-plant waste. During the canning season a substantial portion of the waste treated at the sewage-treatment plant is contributed by the canning plant. During the 1946 season considerable information was gathered on the canning-plant waste and on the sewage-treatment- plant operation. This formed a valuable basis for experiments of the type proposed. Some years prior to this study an attempt was made to improve the existing sewage-treatment-plant operation by installing a flocculation tank for chemical treatment. The flocculation tank was still intact and provided an ideal tank for the planned digestion experiments. Data from Hert's report indicate that during the 1946 tomato season 150
