About Us

RCS Engineering, Inc. was established as a manufacturing consulting company in 1991 By Robert and Sherrie Stewart in Tucson, Arizona. The company relocated from Lawndale, California, where the Stewarts had operated a small machine shop.

In Tucson, the Stewarts began consulting in the field of manufacturing engineering. The company diversified into other areas over the past three decades. Upon Robert Stewart’s death in 2021, the company restructured and focused on climate action and sustainability in Southern Arizona.

This restructure culminated in creating a website that promotes and supports businesses that recycle and reuse in order to make their businesses more cost-effective and to sustain our beautiful Southern Arizona environment.

RCS Engineering, Inc. is a consulting business emphasizing the ability of Southern Arizona businesses to become sustainable by the

practice of recycling or reusing.

To this end, RCS established this website that gathers information so that Arizona businesses may network to cut costs and promote sustainability.
