The thesis was that economies of scale both in purchase and in financing costs might be available to the grey iron foundries for air pollution control equipment, thereby lessening the financial impact in complying with air pollution regulations. This group buying-financing management technique was not known to have been applied to procurement and financing of air pollution abatement devices in any industry. The salient attributes of such an organization were surveyed. The various regulations in the geographical area of concern were examined to establish a tentative grouping of foundries by degree of control needed. Foundry operating procedures and cupola design factors that could affect cupola emissions were evaluated. Performance-cost tradeoff factors were studied, including a possible process change. Quotations were obtained for reverberatory furnace process replacement, and for a venturi scrubber as a function of quantity. Various financing alternatives were explored.
