MAST - An international consulting firm dedicated to designing custom scrap and by-product management solutions

MAST is an international consulting firm dedicated to designing custom scrap and by-product management solutions for manufacturers in the U.S. and Mexico. Our team has spent decades working with industrial manufacturers and can quickly identify opportunities for your company to recover overhead costs and achieve higher yields through materials segmentation and recycling protocols.MAST was forged over 30 years ago as a non-ferrous metal broker headquartered at El Paso, Tx. In 1987 MAST began construction on a secondary lead smelting plant located just 10 miles from U.S. / Mexico Border. This plant used rotary and blast furnace technology to produce 1000 + tons per month of 98% lead purity bullion.

MAST is proud to work with companies in the U.S. and in Mexico. Our experience with bi-national regulations means we can create by-product management programs for clients located on either side of the international border.

Our Mission
To share our experience and knowledge of the manufacturing industry to create profitable, sustainable, efficient and environmentally responsible scrap and by-product management programs that comply with environmental and transportation laws and regulations.
