The Economic and Environmental Benefits of Product Substitution for Organic Solvents
CONSTRUCTION ENGINEERING RESEARCH LAB (ARMY) CHAMPAIGN IL
Pagination or Media Count:
U.S. Army installations require solvents for effective maintenance and equipment refurbishing operations. Spent solvent generation has become a significant environmental and economic concern. Of increasing concern are toxic air emissions, threshold limit values, and increasing restriction on land disposal. Coupled with these environmental issues is the rising cost of both waste disposal and new solvent purchase. This manuscript evaluates the environmental protection and economic benefits of substituting aqueous terpene- based cleaners for petroleum-based Stoddard solvent, currently used in parts cleaning. With characteristics such as low volatility, biodegradability, and reduction of land disposal, terpene cleaners have become the favored substitution alternative. This research showed that implementing terpene cleaner substitution for Stoddard solvent requires a site-specific study of each installation which will include waste recycling, disposal of sludge and rinse water, landfills, contamination of soils and economic analysis.
