Life Cycle Assessment: Greywater Treatment System

Greywater or domestic wastewater (e.g. laundry, sink, and bath water) is characterized for its low organic content that is ideal for water reuse and recycling purposes, in addition to having the potential for significant heat recovery. A full-scale testing of a greywater treatment plant (GWTP) in the Sørhellinga building of the Norwegian University of Life Sciences (NMBU) demonstrates a commercially available technology that is presently being optimized for performance. The development of a Life Cycle Assessment (LCA) to evaluate the environmental performance of this GWTP based on the creation, operation, and disposal of the system is one method to optimize and promote the technology. An LCA can demonstrate the significance of this green technology, particularly with increasing interest in the implementation of environmentally sustainable systems in light of the projected rise in global water and energy demands. This assessment can then be used as a framework for the application of this GWTP in other locations like Canada.
