ACS ES&T Engineering publishes high-impact research and review/perspective articles in all areas of environmental technology and engineering through a highly rigorous peer-review process. It is a specialist journal that aims to serve as an international forum for research and innovation, welcoming contributions on materials, technologies, processes, data analytics and engineering systems that can manage, protect and remediate air, water and soil quality, treat wastes and recover resources. Research contributions that support effective decision-making within complex engineered systems, and are informed by mechanistic science and analytics that describe complex environmental engineering systems are encouraged. Papers that present novel, innovative advancements will be considered across the continuum from lab-based discovery to field-based application. Case/demonstration studies without significant scientific advances and technological innovations will not be considered. Papers containing experimental and/or theoretical methods and knowledge grounded in engineering principles that are integrated with core knowledge from other disciplines are welcome.
