WEBCO Industries is a manufacturer of steel tubing with approximately 350 employees at its facility in Sands Springs, Oklahoma. With senior management commitment WEBCO implemented a waste minimization program in 1991. The facility called on the services provided by technical assistance providers (at both the state environmental agency and local university) to assist in achieving program goals.
Improvements As one of the largest generators of hazardous waste in Oklahoma, WEBCO was motivated to make significant changes to improve efficiency. Some of the steps the facility undertook were:
Savings/Benefits Using the suggestions of technical assistance providers, and combining these with improved technology, material substitution and process controls WEBCO was able to increase sulfuric acid bath life by 50% and decrease the waste generated (by that process) 57% from 1987 to 1995. Additionally, sulfuric acid waste to production ratio was reduced from 9.96% in 1993 to 6.67% in 1994. These process controls resulted in savings of $75,000 in waste disposal costs, during the first 2 years, for an investment cost of $43,000.
Other benefits include:
