WEF Residuals, Biosolids and Treatment Technology Conference

Join us in Kansas City, Missouri, for the 2026 Water Environment Federation (WEF): Residuals, Biosolids and Treatment Technology Conference — the leading international event in advancing the role of biosolids and resource recovery.  

We are proud to be one of the conference app sponsors. We hope to see you at any of our technical sessions where you can meet our residuals and biosolids experts, and discuss the latest developments in the aspects of biosolids treatments and management.
