Industrial Waste Recycling into Modular Construction structures

  Industrial processes generate wastewater streams containing strong mineral acids (e.g., HCl, H₂SO₄, HNO₃) and dissolved heavy metals.

These effluents pose serious risks to municipal water systems and environmental health if discharged untreated. 

Traditional treatment methods often fail to fully neutralize acidity or isolate metal ions for safe disposal or reuse.

High energy costs and chemical consumption make conventional separation and filtration economically inefficient. 

Solid byproducts from treatment are typically landfilled, missing opportunities for material recovery and circular use. 

There is a need for scalable, low-energy solutions that recover clean water and convert waste solids into construction-grade materials.  

     Regenerating industrial acidic and metal-laden wastewater is mission-critical for the semiconductor and accelerated computing industries, where ultrapure water (UPW) is both a foundational input and a sustainability bottleneck. Each silicon wafer undergoes over a thousand precision-cleaning steps, consuming vast volumes of water and generating effluents rich in nitric acid, sulfuric acid, heavy metals, and solvents.   

Without advanced regeneration systems, these toxic streams threaten environmental compliance and jeopardize operational continuity in fabs and AI data centers.

TENGENA’s multi-phase wastewater regeneration platform transforms acidic, metal-laden effluents into reusable water and construction-grade mineral outputs, delivering zero-emission, reagent-free performance,  across integrated stages.  These stages form a closed-loop, high-throughput water regeneration system that supports fab-scale operations, reduces hazardous waste that sedimented to integrate into construction materials.
