Welcome to CHAR Technologies, Home of SulfaCHAR™

Developed by CHAR Technologies, SulfaCHAR™ is a cost-effective, convenient, zero-waste targeted gas cleaning solution for the growing three billion dollar global problem caused by toxic and corrosive hydrogen sulfide in the renewable natural gas industry. SulfaCHAR™ filters hydrogen sulfide out of renewable natural gas, allowing users to drastically reduce their maintenance costs.

SulfaCHAR™ is:

Cost-effective

• SulfaCHAR™ is the most cost-effective H₂S removal product based on cost per kilogram of H₂S removed, providing over 50% savings compared to similar systems
• The simplicity of the system requires little capital infrastructure and low operator attendance, making it an accessible option for facilities of any scale.

Convenient

• SulfaCHAR™’s high sulfur capacity, compared to similar systems, means that the material lasts longer and requires less change outs
• SulfaCHAR™ is non-toxic and doesn’t solidify into large pieces making it easier to change-out
• Minimal monitoring required.

Zero-waste

• SulfaCHAR™ is made from organic waste material, such as anaerobic digestate
• SulfaCHAR™ converts hydrogen sulfide into beneficial forms of sulfur, allowing spent SulfaCHAR™ to be reused as a sulfur rich biochar fertilizer.
