Segment Reporting [Abstract] |
Segment Reporting | Segment Reporting Overall The Company has one reportable segment – advanced purification technologies or "APT." The APT segment primarily manufactures and sells AC based environmental remediation products, comprised of PAC and GAC, and other chemicals used to capture and remove contaminants for coal-fired power generation, industrial, municipal water and air, water, and soil treatment and remediation markets. The Company derives revenue primarily in the U.S. and manages the business activities on a consolidated basis. The Company manufactures all of its finished goods at the Red River Plant. The Company's chief executive officer is its chief operating decision maker ("CODM"). The CODM assesses performance for the APT segment and decides how to allocate resources based on net income that also is reported on the statement of operations as consolidated net income. The measure of segment assets is reported on the balance sheet as total consolidated assets. The CODM uses net income to evaluate income generated from APT assets (return on assets) in deciding how to allocate cash flows from operations within the APT segment. Net income is used to monitor budget versus actual operating results in assessing performance of the APT segment. The level of detail used in reviewing operating financial performance and managing the business is contained in the Company's Condensed Consolidated Statements of Operations. Products and services The Company operates in one segment, APT, and all revenue reported to external customers represents sales of APT products and are presented in the Condensed Consolidated Statements of Operations. Geographic areas The Company is domiciled in the U.S. The table below shows revenue by country for the three and six months ended June 30, 2025 and 2024.
