Title:Waste Management Study of Foundries Major Waste Streams: Phase II
Author(s):McKinley, Marvin D.; Jefcoat, Irvin A.; Herz, William J.; Frederick, Christopher L.
Subject(s):Foundries -- Refuse and refuse disposal
Abstract:Research on emission control and waste disposal is the number one priority within AFS. In an industry survey conducted by AFS, ten top areas of concern were outlined, headed by sand system waste and emissions from molding, pouring, melting and shakeout in iron and steel green sand foundries. The objective of the present program was to define the foundry waste streams and emissions, establish where the streams originate, and define their make-up. A primary driving force for this work is the Clean Air Act Amendments of 1990 which will set new regulations for air emissions from foundries for 189 hazardous air pollutants (HAP) by 1997. The focus of the research was on the nature of the foundry waste streams in the form of air emissions from processes of coremaking, molding, pouring, and shakeout and to establish their origin and their makeup. Binder chemicals are a major potential contributor to emissions from coremaking and subsequent processes. The Phase I report included a review of all available information. Sources were the technical literature, suppliers of chemicals to foundries, AFS workshops, USEPA Office of Air Quality Planning and Standards, technical meetings, and visits to foundries. This Phase II report covers an extension of the research to include emission factors derived from the limited data available for the common binder systems. These data will be useful for making order-of-magnitude estimates of emissions. Also included is a brief discussion of treatment technologies currently available for air emissions, along with a list of vendors for such equipment.
