Company Summary

SulfaCHAR is the cost-effective, convenient and zero-waste solution to the growing $3.5B per year global renewable natural gas cleaning industry. With patented SulfaCHAR, toxic and corrosive hydrogen sulfide is filtered out of the gas, allowing users to drastically reduce their maintenance costs. SulfaCHAR is unique – it is the only product that effectively converts hydrogen sulfide into a fertilizer, and not another waste requiring disposal.
