Overview
Arbok-BioLi extracts lithium using a bio-alcohol Anti-Solvent fermented from organic waste, precipitating lithium salts directly from brine and converting them to Li₂CO₃ or LiOH — instantly, instead of 12–18-month evaporation ponds. It eliminates toxic reagents, cuts water loss by up to 95 %, returns >90 % of water, and uses waste as both feedstock and energy source (50–70 % self-powered), running as a zero-waste closed loop. It complements large-scale ARBOK vacuum lithium recovery as a low-throughput, low-footprint, waste-fed route.
Applications
Primary use cases: localized lithium extraction from salt-lake, geothermal, and industrial brines; waste-to-value lithium hubs; regional battery supply.
Industries and users: battery supply chain, mining, regional utilities, waste management.
Scale: modular, 100 t organic waste/day per module → ~90 t Li₂CO₃/year; regional deployment.
Operating Principle
Organic waste is fermented into bio-alcohol, which acts as an Anti-Solvent: added to brine, it precipitates LiCl, which is filtered and converted to Li₂CO₃ or LiOH; the alcohol is regenerated and reused (losses <5 %), and low-grade alcohol fractions are burned in fuel cells for energy. Closed-loop, AI-controlled fermentation (pH, temperature, substrate feed).
Limitations: lower throughput than large-scale ARBOK lithium systems; needs lithium-bearing brine plus an organic-waste stream; brine concentration adjustment if too dilute; the fermentation yeast strain and Anti-Solvent formulation are engineered in-house and tuned for selective lithium precipitation.
Key Parameters
Extraction efficiency: 80–95 %. Water return: >90 % (consumption −95 %). Bio-alcohol recovery: >95 %. Energy self-sufficiency: 50–70 %.
Throughput: 100 t organic waste/day per module → ~90 t Li₂CO₃/year (~0.25 t/day). Speed: instant precipitation vs 12–18 months evaporation. Service life: 15 years. CO₂: up to −80 % vs gasoline (bio-alcohol fuel).
Compatible feeds: salt-lake, geothermal, industrial brines.
Architecture and Components
Bio-waste storage; bioreactors (fermentation); alcohol regeneration column; Anti-Solvent mixing; filtration + conversion unit (Li₂CO₃/LiOH); fuel cells (energy recovery); SCADA/Digital-Twin control. Modular; integrates with ARBOK vacuum evaporation for brine concentration + water recovery.
Advantages
Technical: instant precipitation, no evaporation ponds; closed-loop, zero-waste; 50–70 % self-powered.
Economic: OPEX $5 000–7 000/t Li₂CO₃ vs $20 000–25 000/t conventional (3–4× cheaper); 60–80 % margin; payback 2–3 years; $50 million lifecycle cash flow per module.
Environmental: zero discharge, 95 % water savings, no chemical sludge, −80 % CO₂ (bio-fuel).
Strategic: localized lithium from waste; reduced dependence on fossil-based reagents and on long-lead mining/evaporation.
Integrations
Pairs with ARBOK vacuum evaporation (brine concentration + drinking water), ARBOK fuel cells (energy), and large-scale ARBOK lithium recovery; fits existing waste-management and brine-extraction infrastructure.
Deployment & Operation
Steps: install module → connect organic-waste stream → connect brine source → operate closed loop. Compact footprint (≈ an oil-storage tank); AI-controlled fermentation; modular regional deployment.
TRL
TRL 8 (confirmed by Michael). System complete and qualified: full process design and ARBOK-evaporation integration, validated through test and demonstration. Remaining to 9: first full commercial deployment and long-run operational data.
Market Potential
Lithium demand is surging for batteries while conventional brine evaporation is slow, land- and water-intensive, and concentrated in a few regions. A waste-fed, water-saving, fast-precipitation route fits water-stressed lithium regions and circular-economy/waste-to-value policy.
Typical Project Economics
OPEX $5 000–7 000/t Li₂CO₃; revenue ~$1.35–2.7 million/year from lithium plus ~$580 000/year from by-products; ~$50 million lifecycle cash flow per module over 15 years; payback 2–3 years. CAPEX modular (to be specified per site).
Risk Factors
Throughput limits vs large-scale systems; needs co-located brine + organic-waste; fermentation/Anti-Solvent scale-up; pilot/certification data pending; feed variability.
