Description:

Biogas is generated in anaerobic digesters and landfills but contaminants such as hydrogen sulfide (H2S) must be removed to prevent damage to engines and pipelines. Worldwide, it is estimated that over $1 billion is spent annually on removing H2S from biogas before it can be used as renewable natural gas for heating or for the production of electricity. Currently-available products for scrubbing can be expensive and need to be landfilled after use. Enter SulfaCHAR™, a zero-waste and cost-effective way of purifying biogas – while also transforming the H2S into a valuable sulfur-rich fertilizer that increases crop yields. This project will focus first on designing and building a SulfarCHAR™ production facility, then on using the SulfaCHAR™ scrubbing units to remove H2S from biogas, and testing spent SulfaCHAR™ as an agricultural fertilizer.
