REMEDIATION · MARKET 01

Heavy metals. PFAS. Stormwater.

Spec-grade activated biochar for the contaminants that won't go away on their own.

H/Corg <0.4 pH 7.5–9.5 PFAS Adsorption

Engineered media, not commodity char. Remediation performance comes from purpose-built formulation. NextChar develops application-engineered biochar media for heavy metals and emerging contaminants, with specifications quoted per project and treatability testing recommended for every site.

APPLICATIONS

Four sub-markets. One material standard.

Activated biochar from the NextChar network meets the surface area and purity thresholds for each remediation pathway.

Brownfields

In-Situ Stabilization

  • 2–5% w/w application immobilizes As · Cd · Cr · Cu · Pb · Zn at contaminated sites
  • Certificate of Analysis per lot
  • Particle size matched to injection specs
Industrial Water

Fixed-Bed Filtration

  • Granular biochar columns (0.5–2.0 mm) for industrial wastewater pre-treatment
  • Lower-cost GAC alternative
  • Activated grades available to >800 m²/g; specifications quoted per project
  • COA includes pore size distribution
MS4 Stormwater

Stormwater Bioretention

  • Coarse particle (2–6 mm) in rain gardens and bioswales
  • Documented Zn, Cu, TSS, and hydrocarbon removal rates in COA
  • LEED eligible
  • Supports MS4 stormwater program documentation
Emerging Sector

PFAS Adsorption

  • Hydrophobic surface zones partition PFAS compounds
  • Biochar-based sorption treatment for PFAS-contaminated biosolids
  • Our fastest-growing solution
  • Third-party verification available
SPECIFICATIONS

Material specifications for remediation.

Lots shipped against a remediation PO are audited against NextChar's QA/QC standard, with third-party laboratory analysis and a Certificate of Analysis on each qualifying lot.
