Zoltek celebrates the founder’s 80th birthday

St. Louis, Missouri, USA, Dec. 06, 2022 (GLOBE NEWSWIRE) — Zoltek Corporation, the largest global manufacturer of industrial grade carbon fiber, has recently celebrated the 80th birthday of its founder, Zsolt Rumy.

Born in December 1942 in Budapest, Hungary, Mr. Rumy was a carbon fiber industry pioneer that ultimately changed the carbon fiber world. He created the first industrial–grade carbon fiber made to compete against other common building materials, and created Zoltek Corporation to drive the commercialization of carbon fibers.

Mr. Rumy fled Soviet communism after the Hungarian Revolution in 1956, and arrived in the US as a 14–year old war refugee through the International Red Cross and Catholic Charities. He later graduated with a chemical engineering degree from the University of Minnesota, accepted a position with Monsanto Company and moved to St. Louis, Missouri in 1966. After several years of corporate sales and engineering jobs in the chemicals industry, he started his own distribution business in 1975. After years of selling carbon and graphite products, he plunged into carbon fiber manufacturing in 1988 with the acquisition of Stackpole Fibers in Lowell, Massachusetts.

His vision of a low–cost carbon fiber began on a pilot line in St. Louis, MO, and later became realized after acquiring an acrylic fiber factory, Magyar Viscosa, back in his native Hungary. He led a team of engineers that were able to convert this acrylic fiber factory to the world's first low–cost carbon fiber factory. Zoltek repeated this feat by acquiring a second acrylic fiber factory in Mexico, and the rest is history.

In 2014, Zoltek was acquired by Toray Industries of Japan, who at the time was the world's largest aerospace carbon fiber producer. With the support of the Toray Group, Zoltek has now grown to the largest carbon fiber manufacturer in the world, with more than 30,000 MT of annual capacity.

"Zsolt is a true pioneer who lived the American dream. He built a company and changed the carbon fiber industry forever. We are all honored to be part of his journey and grateful for his leadership and friendship", EVP of Sales & Marketing Dave Purcell. "Now it's our job to carry his vision forward and bring our low–cost carbon fiber to new applications around the world,'' he added.

"The Will To Do, The Soul Dare" is an autobiography that details Zsolt's extraordinary life experiences and his visionary spirit and courage that revolutionized the carbon fiber industry. Zsolt's book is available in major book stores and Amazon. You may also request a free copy of Zsolt's book (while supplies last) by sending your request to jschmidt@twinspringsinv.com.

Zsolt Rumy and Dave Purcell are current board members of Zoltek Corporation.

About Zoltek: Zoltek Corporation is the most trusted manufacturer of cost–efficient and customer–centric industrial grade carbon fiber used for automotive parts, wind turbine blades, thermoplastic compounding, marine infrastructure, and many more. In 2014, Zoltek joined the Toray Group (Japan) which has advanced the company's technology and strengthened the technical and financial resources and positioned the company for further growth as the most reliable global leader of carbon fiber.

Calgon Carbon Reactivation Study Shows Removal and Destruction of PFAS

Pittsburgh, PA, Dec. 06, 2022 (GLOBE NEWSWIRE) — A new study by Calgon Carbon Corporation ("Calgon Carbon"), a wholly owned subsidiary of Kuraray Co., Ltd. (TYO: 3405) ("Kuraray"), has provided a definitive response to a persistent question about the fate of PFAS during reactivation of activated carbon. Reactivation is a high temperature thermal process that is commonly used by municipalities and industrial users to recycle their used activated carbon and destroy contaminants it has removed.

"The single–biggest conclusion from the study is that PFAS compounds are effectively removed from spent carbon through the reactivation process, as well as showing greater than 99.99% destruction of PFAS through our furnace and abatement system," explained Rebecca DiStefano, Senior Applications Engineer at Calgon Carbon.

Remediation–The Journal of Environmental Cleanup Costs, Technologies, & Techniques, featured the findings of Calgon Carbon's study in a peer–reviewed article published in the autumn issue of the esteemed quarterly journal that focuses on the practical applications of remediation techniques and technologies.

"The data detailed in our article effectively demonstrated the removal of PFAS compounds from granular activated carbon (GAC) and greater than 99.99% destruction of PFAS compounds through the furnace and off–gas abatement system," said DiStefano, the lead author of the Remediation article.

The study's findings come at a time of growing concern and increased focus about the impact of PFAS, often referred to as "forever chemicals" because of their inability to break down over time in the environment.

"This is research that no one else in the industry has published.," DiStefano said. "We don't want to have these unknowns stay out there and linger in people's minds. We wanted to answer these questions and move the industry forward and continue promoting GAC as the best available treatment (BAT) technology for removing PFAS."

Calgon Carbon's FILTRASORB GAC, sourced from bituminous coal, has demonstrated superior PFAS–removal capabilities compared to other carbons for two decades.

GAC is the most widely used and well–established treatment technology for the removal of PFAS contaminants from drinking water and wastewater. Thermally treating GAC at the end of its useful service life "" known as spent carbon "" is called reactivation, a process that vaporizes and destroys adsorbed contaminants at extremely high temperatures and restores the GAC to a near–virgin state so it can be reused.

In the first stage of Calgon Carbon's proprietary reactivation process, PFAS–laden GAC is heated in a furnace for several hours at temperatures of up to 1750 degrees Fahrenheit, imparting enough energy to break down PFAS's carbon–fluoride bonds, the strongest in chemistry.

The off gas from the reactivation furnace then moves into an abatement system, which features a thermal oxidizer/afterburner designed to destroy any organics that were not destroyed in the furnace. From there, it proceeds through a scrubber to neutralize any acid gases, such as hydrogen fluoride, and remove them from the abatement air. Finally, it passes through a baghouse to eliminate particulate matter.

"It's a combination of our reactivation furnaces and the abatement systems that achieves these very high levels of destruction," said John Matthis, Global PFAS Team leader at Calgon Carbon. "With other technologies, you may be removing PFAS from the water, but the question is, what do you do with that media once it has PFAS on it? Activated carbon and reactivation are unique because not only are we removing the contaminants from your water, we also are effectively removing them from the carbon "" and from the environment as well."

For its study, Calgon Carbon enlisted the services of an independent, third–party vendor to test air samples for 36 PFAS compounds. Another third–party vendor analyzed well water and treated motive water samples for PFAS, as well as analyzing samples of spent carbon, reactivated carbon, abatement dust, and bicarbonate raw material for extraction and targeted PFAS.

Since creating the first activated carbon products from bituminous coal in the 1940s, Calgon Carbon has been a pioneer in developing high–performing granular activated carbon products for water purification.

Jenalle Brewer, Senior Vice President "" Drinking Water, Innovative Carbon Tech & Global Business at Calgon Carbon said, "PFAS is portrayed in the media as a relatively recent problem. However, we've been offering treatment solutions for PFAS for more than 20 years. Our FILTRASORB activated carbon products help to ensure that "forever chemicals' are forever no more. It's a problem people thought they had to live with, but as our study has proven, they really don't."
