Metal Fabrication Best Practices – New Project for 2021
Metal Manufacturing and Fabrication is an important industry sector In Minnesota, with more than 1,000 machine shops that employ over 10,000 people and generate more than two billion dollars in annual sales. Businesses in this sector realize the extra costs associated with managing waste streams as well as use of excess energy, water or time. Identifying and implementing the best options to reduce waste takes time away from critical production efforts and may end up on an ever increasing “to do” list.
The Minnesota Technical Assistance Program (MnTAP) is a no cost, technical assistance provider located at the University of Minnesota with a mission to help Minnesota businesses improve efficiency and save money through energy, water and waste reduction. MnTAP is launching a research project in collaboration with the Minnesota Precision Manufacturing Association (MPMA) to define current, non-confidential, best practices in the metal fabrication industry for hazardous material and waste reduction. Technical assistance services from MnTAP engineers will be available to metal fabrication businesses as part of this project.
Fabricated metal processes generate various waste streams; oily wastes from machining operations, heavy metal bearing streams from surface treatment and plating operations, hazardous and regulated solvents, alkaline and acid solutions from metal cleaning, chloride discharges from softened water and other sources. In addition to materials, energy efficiency and water conservation opportunities may be available to help businesses improve their overall sustainability performance and reduce operating costs.
We want to hear from you! If you are a machine shop, or involved in metal fabrication, MnTAP would like to hear your story about the changes that have been made to reduce pollution or costs, regulatory concerns or just touch base and tell us how you are doing. Sign up for a confidential informational interview that can help uncover options for increased process efficiency.

Recycling Contaminated Water Streams – 2017 Intern Project
Johnson Screens, a brand of Aqseptence Group Inc. is the leading brand for screens used in a wide range of industries. In 2017 Johnson Screens hosted a MnTAP Intern to reduce the impact that its production processes have on the environment. The company used approximately 10 million gallons of water annually to quench the welds on the screens at a cost of $120,000 per year. As a company conscientious of its footprint, Johnson Screens was seeking to reduce the amount of water used by 30% by improving the water recycling systems.
The welding machines that produce screens were also producing a water discharge stream contaminated with particulates, burnt oil, free oil, emulsified oil and lubricant. To clean up the water enough for reuse, the intern recommended and the company implemented a recycling system comprised of a centrifuge and ultrafiltration column at each machine to purify and remove all contaminants except for metal ions.
By implementing this change, the company saved 940,000 gallons of water and $7,000 annually. In addition, this same purification system could be applied to other machines for an additional 1.6 million gallons of water and $12,000 savings annually.
