Birchtech Demonstrates Utility-Validated Carbon Rejuvenation with Performance Comparable to Virgin Activated Carbon

Executive Summary

• Birchtech announced successful demonstrations of its Carbon Rejuvenation™ process, showing thermally‑rejuvenated spent granular activated carbon (GAC) performs comparably to virgin GAC in removing PFAS for municipal water utilities.
• The results support the technical and commercial viability of reusing spent GAC, offering a lower‑cost, environmentally‑friendly alternative to landfill disposal and virgin carbon purchase.
• The regional reactivation model aligns with utility priorities (cost discipline, emissions reduction, supply‑chain simplification) and positions Birchtech for broader commercialization in the PFAS treatment market.

Key Details

• Demonstrations were conducted at Birchtech Design Centers using spent GAC sourced directly from active municipal water systems.
• Performance was measured against utilities’ standard benchmarks; treated GAC met all required PFAS removal standards, matching virgin carbon performance.
• Thermal reactivation destroys embedded PFAS contaminants, allowing the same GAC media to be redeployed without landfill disposal.
• Expected benefits of the Carbon Rejuvenation process:
• Reduced reliance on virgin raw materials and associated procurement costs.
• Lower total lifecycle cost for utilities through shorter transportation distances and eliminated disposal fees.
• Regional deployment reduces emissions, supports supply‑chain resilience, and aligns with utility rate‑stability goals.
• CEO Richard MacPherson highlighted that the demonstrations validate the cost‑effective, localized reactivation approach and its fit with utility priorities around sustainability and infrastructure resilience.
