Environmental & Remediation
Water and soil cleanup solutions using engineered biochar and partner-activated carbon.
Engineered wood biochar (~400 mĀ²/g, low ash <2%, pH 8.5ā9.0; Chip/Medium/Small/Powder; 1 cu ft bags & 1 cu yd super sacks). Activated grades available via identified partners for PFAS/VOC-critical duty.
Partner-Activated Carbon (GAC) or Small Biochar
Application Rate
GAC for compliance; Small biochar for pre-treatment/blending
Expected Results
>99% PFAS removal with GAC; biochar extends GAC run-time ā„25% in blended-bed configuration
Why This Grade?
Fine particles for water contact systems; GAC for compliance, biochar for pre-treatment to extend GAC life
Track A: Partner-Activated Carbon (GAC)
For PFAS compliance under the 2024 PFAS NPDWR, use steam-activated GAC with a documented reactivation program (e.g., NORIT Pryor, validated 99.98% PFAS destruction; NSF/ANSI 61). GAC is EPA's Best Available Technology (BAT) for PFAS removal and can be regenerated multiple cycles.
Track B: Engineered Biochar Pre-Treatment
Use as pretreatment/polishing or for non-regulated odor/organics interception to extend GAC runtime. NOT for PFAS complianceābiochar is not EPA BAT for PFAS. Install upstream of primary GAC beds or in polishing cells. Confirm economics with a side-by-side pilot to document GAC life extension and cost savings.
Oklahoma Fit
Municipal water systems partnering with NORIT Pryor reactivation facility (NSF/ANSI 61 certified, 99.98% PFAS destruction validated)
Pricing Context
At $1000/ton, biochar pre-treatment reduces total GAC consumption and extends reactivation cycles. Expected benefit: Extends GAC run-time ā„25% in blended-bed configuration.
Small or Powder (water); Medium (soil)
Application Rate
Water: Small/Powder in contact systems; Soil: 2-5 t/ac Medium biochar
Expected Results
30-70% TPH reduction within 60-90 days; odor and sheen suppression within one week
Why This Grade?
Small/Powder for water contact systems; Medium for soil mixing. ~400 mĀ²/g provides adsorption + microbial habitat.
The high surface area (~400 mĀ²/g) and balanced pore structure of InfiniteEco biochar captures oil compounds while creating favorable conditions for microbial breakdown. For produced water treatment, use Small or Powder grades in contact systems. For contaminated soil remediation, incorporate Medium biochar at 2-5 t/ac to accelerate natural attenuation. Verify TPH decay locally as performance varies by site conditions. Rates assume ~400 mĀ²/g biochar; lower-grade chars may require 2-3Ć more.
Application: Water: Use Small/Powder in filtration systems; Soil: Incorporate Medium biochar at 2-5 t/ac and blend into contaminated zones
Oklahoma Fit
Oil-patch spill remediation and produced-water storage areas in Canadian and Kingfisher Counties
Pricing Context
At $1000/ton, effective cost is $500/ton equivalent vs commodity biochar requiring 2-3Ć dosage. Payback: <1 year through accelerated site closure.
Medium Biochar + Gypsum
Application Rate
Gypsum 2 t/ac + Medium biochar 3-8 t/ac depending on EC/SAR
Expected Results
9-10% salinity reduction, 20% yield gains (meta-analysis 100+ studies); 40-70% SAR reduction in sodic soils
Why This Grade?
Biochar's alkalinity and pore structure improve infiltration and CEC, while gypsum provides Naāŗ exchange
Biochar's alkalinity (pH 8.5-9.0) and pore structure improve infiltration and cation-exchange capacity, while gypsum provides calcium for sodium exchange. Together they rehabilitate saline and sodic fields by reducing sodium adsorption ratio (SAR) and improving soil structure. Apply gypsum at 2 t/ac with Medium biochar at 3-8 t/ac depending on soil EC and SAR levels. Benefits include improved infiltration, reduced crusting, and restored crop productivity.
Application: Broadcast gypsum and Medium biochar together; incorporate 4-6 inches deep; irrigate to initiate Naāŗ exchange
Oklahoma Fit
Western irrigated counties and drill-pad reclamation zones
Pricing Context
At $1000/ton biochar + $200/ton gypsum, total cost is $3400-8400/ac. Payback: 1-2 years through yield recovery and reduced water requirements.
Small or Powder Biochar + Iron-Sand
Application Rate
5-10% by volume biochar in filter cells, blended with iron-coated sand
Expected Results
80-90% phosphorus reduction (Coon Creek/Stantec full-scale project); 30-60% nitrogen capture; media life ā2 years before reuse as soil amendment
Why This Grade?
Fine particles mix uniformly with iron media; high surface area captures dissolved nutrients and organic matter
Small or Powder biochar (~400 mĀ²/g) provides structure and sorption capacity when blended 5-10% by volume with iron-sand (Fe-coated media) in bioretention cells. The biochar captures dissolved organic matter and ammonia while iron media drives phosphate binding. Full-scale projects (e.g., Coon Creek/Stantec, Minnesota) demonstrated 80-90% phosphorus reduction; results are site-specific and depend on influent loading. Ideal for green infrastructure, parking lot runoff, agricultural drainage, and lake protection projects. Spent media can be reused as soil amendment after 2-3 years.
Application: Mix Small/Powder biochar with iron-sand in treatment cells; replace media every 2-3 years depending on loading; reuse spent media as soil amendment
Oklahoma Fit
Municipal stormwater retrofits and lake protection projects (Grand Lake, Kaw, Thunderbird)
Pricing Context
At $1000/ton, biochar component adds $50-100 per treatment cell vs conventional media. Payback: 1-3 years through reduced algae control costs and improved water quality.
Medium Biochar + Compost
Application Rate
3-10 t/ac Medium biochar blended with compost
Expected Results
60-90% drop in TCLP metal mobility; complete vegetative cover within 12 months
Why This Grade?
Biochar's surface groups and alkalinity immobilize Pb, Cd, Zn, and As, reducing leachable toxicity
Biochar's surface functional groups and alkalinity (pH 8.5-9.0) immobilize lead, cadmium, zinc, and arsenic through adsorption and precipitation, reducing leachable toxicity measured by TCLP (Toxicity Characteristic Leaching Procedure). Blend Medium biochar with compost at 3-10 t/ac depending on contamination levels. The biochar stabilizes metals while compost provides organic matter and nutrients for vegetation establishment. Sites achieve complete vegetative cover within 12 months, reducing erosion liability and supporting phytostabilization.
Application: Blend Medium biochar with compost; spread and incorporate into top 6-12 inches; seed with native or tolerant species
