From Biosolids to Value, for a Sustainable Future

We design and deploy industrial-scale pyrolysis systems that convert waste biomass and biosolids into biochar, carbon credits, and renewable energy, permanently eliminating PFAS in the process.

BiosolidsManagement Challenges

Rising volumes of biosolids waste
High and increasing management costs
Energy-intensive treatment and disposal
Significant methane and greenhouse gas emissions from landfills
Risk of contaminant spread through land application

Pyronexus Solution

Eliminates or significantly reduces tipping fees
Destructs harmful contaminants, including PFAS, using pyrolysis conversion at 700+°C
Cuts landfill methane emissions through diversion and conversion
Recovers energy from waste
Converts biosolids into biochar for low-carbon material markets

How It Works

Dewatering biosolids

(~80% moisture)

Thermal drying

(~20% moisture)

Pyronexus pyrolysis conversion

(700+°C in oxygen-limited environment)

PFAS Destruction Zone

(C-F bonds broken at >700°C, syngas without carryover of volatiles)

High-quality biochar production

Energy Recovery

(~5 MMBtu/hr available heat reused or converted to electricity)

The PFAS Problem in the US Biosolids

PFAS ("forever chemicals") have been detected in approximately 80% of municipal biosolids in the United States.
EPA's 2024 final PFAS rule classifies PFOA and PFOS as hazardous substances.
Land application of contaminated biosolids now carries major liability.
Over 2,300 sites across the U.S. have confirmed PFAS contamination linked to biosolids application.
