For more than 150 years, Church & Dwight and its Arm & Hammer branded products have been synonymous with sodium bicarbonate expertise. This expertise has gone hand-in-hand with our pioneering efforts in environmental protection.

It is this experience and technological leadership that has led Church & Dwight to develop innovative and practical solutions for one of today's most pressing environmental challenges: the control of acid gas emissions. Central to our success in this field is dry injection technology. Dry injection is one of several technologies available for acid gas removal, and one worth consideration when evaluating your emission control needs. Dry injection systems are economical and easy to retrofit. The straightforward design makes for low maintenance costs and provides a clear advantage versus other technologies.
