Tantech Participated in Setting International Standards for Bamboo-based Activated Carbon

LISHUI, China, Dec. 12, 2022 /PRNewswire/ -- Tantech Holdings Ltd (NASDAQ: TANH) ("Tantech" or the "Company") today announced that its subsidiary, Zhejiang Tantech Bamboo Charcoal Co., Ltd., had received a certificate from the Bamboo and Rattan Technical Committee of the International Organization for Standardization (ISO/TC 296). This certificate acknowledges proactive participation and significant contribution of Tantech in setting a new set of international standards (ISO 5946:2022) on general specifications of bamboo-based activated carbon, which aims at accelerating technological innovations, facilitating global trade and promoting sustainable uses of renewable bamboo resources through guiding production processes, stipulating quality requirements and specifying test methodologies. Previously, ISO had awarded three similar certificates to Tantech to recognize its valuable roles in establishing international standards for manufacturing and marketing bamboo charcoal products (ISO 21626-1/2/3: 2020), which cover a series of technical specifications and classifications on generalities (Part 1), fuel applications (Part 2) and purification applications (Part 3). All these ISO standards are instrumental in providing fundamental knowledge and practical tools for grading different kinds of outputs according to their physicochemical characteristics, such as verifiable measurements in moisture, ash, fixed carbon content, calorific value and formaldehyde/TVOC adsorption capacity.

Mr. Wangfeng Yan, CEO of Tantech, said, "We have invested intensively in strengthening our R&D capabilities and reinforcing our research partnerships, in order to achieve better technologic excellence and gain stronger market competitiveness. Being able to continuously participate in assisting ISO to formulate and update international standards on bamboo charcoal and activated carbon has not only given us precious opportunities to learn from industrial leaders but also stimulated us to upgrade our production processes and revamp our quality assurance systems. All these will surely help us to better serve our customers and to attain higher acceptance of our products and services in the market."
