Who we are . . .

International Steel Services, Inc. (ISSI) was incorporated in 1989 to provide services to the steel industry in environmental areas. Providing
technology and services in waste water and air pollution control, ISSI specializes in the design, construction and operation of hydrochloric acid (HCl) recycling facilities. These acid regeneration facilities specialize in the production of high-purity iron oxide. ISSI also specializes in the marketing of iron oxide throughout the world, especially to hard and soft ferrite producers.

ISSI can be deemed the successor company of PEROX, which was a subsidiary of Pennsylvania Engineering. PEROX started building spray roaster type recycling facilities in the early 1970's and owned and/or operated three plants in the United States. In the late 1980's, PEROX ceased its activities, and ISSI purchased the technical property of PEROX.

Our goal is to earn, maintain and enhance ISSI's worldwide leadership in the design, installation and operation of waste hydrochloric acid (HCl) recycling and iron oxide production facilities.

We strive to develop and constantly search for optimum economical and technical solutions, tailor-made for the diversified needs of our customers.

Specifically, our aim is to provide an optimum balance for our customers' waste recycling requirements and the economic value of the by-product iron oxide.


What is Acid Recycling?

Acid recycling is a process by which waste hydrochloric acid (HCl), in the form of ferrous chloride, from steel pickling operations is treated to produce recycled hydrochloric acid (HCl) and iron oxide.

Why Acid Recycling?

  • Eliminate costly disposal alternatives
  • Provide secondary use for rinse water as process water in the recycling process
  • Plants operate on most common gases


What can ISSI offer?

  • Experience . . . the ISSI management staff has over 50 years of combined experience in the acid recycling industry.
  • In the past 10 years, ISSI has built 27 acid regeneration plants ranging in size from 5 GPM to 104 GPM.
  • Design to handle carbon-based steel and stainless steel waste acids.
  • Advanced purification technology to produce high purity iron oxide.
