Birchtech’s Carbon Rejuvenation™ (rjGAC)™

Carbon Rejuvenation (rjGAC) vs. Traditional Approaches

Accurate analysis and comparison of activated carbons — including virgin, spent, and traditionally reactivated — both pre- and post-treatment equips utilities with a fully optimized approach to address contaminant removal.

Virgin GAC

High upfront cost. Supply chain dependent. Standard performance baseline for comparison. No PFAS destruction capability.

Carbon Rejuvenation (rjGAC)

Lower lifecycle cost. Comparable adsorption performance. Destroys PFAS compounds. Reduces reliance on virgin materials. Regional reuse model.

Traditional Reactivation

Partial capacity restoration. Does not destroy PFAS. Higher transportation and disposal costs. Limited contaminant specificity.

The PFAS Compliance Challenge

U.S. water utilities face over $47 billion in compliance costs due to new EPA PFAS/PFOS regulations. Traditional approaches rely heavily on virgin granular activated carbon — a costly, resource-intensive material with significant supply chain and disposal challenges.

Birchtech's Carbon RejuvenationTM (rjGAC) offers a fundamentally different approach: restore spent carbon to comparable performance levels, destroy PFAS in the process, and deliver practical, cost-efficient solutions that reduce lifecycle costs by up to 30%.

With a decentralized model supporting regional carbon reuse, Carbon RejuvenationTM (rjGAC) aligns with utility priorities for sustainability, supply-chain resilience, and capital efficiency — while integrating environmental benefits directly into operating economics.

A Sustainable
Alternative to Virgin Carbon

Birchtech's Carbon RejuvenationTM (rjGAC) Services use advanced processes that restore and enhance spent carbon, enabling continued adsorption performance while reducing reliance on virgin raw materials.

As a cost-effective alternative to virgin carbon, Carbon RejuvenationTM (rjGAC) reduces new carbon production, conserves resources, and lowers lifecycle costs. When applied to spent GAC, the used media is restored for reuse while PFAS compounds are destroyed.

Birchtech provides expert recommendations on the optimal blend of rejuvenated and virgin carbon for PFAS compliance — using performance data and in-depth analysis.
