This metric is intended to capture the total amount of water the organization reused or recycled during the reporting period.
The scope of this metric includes results from land or facilities directly controlled by the organization (i.e., land for which the organization controls land use through direct operation or management, including situations in which the organization's employees cultivate the land directly) and land or facilities indirectly controlled by the organization (i.e., land that the organization supports or influences but does not directly cultivate or manage). Examples in which an organization indirectly controls land may include purchase contracts, sourcing from farmer cooperatives, and providing products and services to farmers and other organizations that cultivate and manage land.
Water reused or recycled is the act of processing used water and wastewater through another cycle before discharge to final treatment and discharge to the environment. Water recycling and reuse can include wastewater recycled back in the same process or higher use of recycled water in the process cycle; wastewater recycled and reused in a different process, but within the same facility; and wastewater reused at another of the organization’s facilities.
This metric includes both water treated prior to reuse and water not treated prior to reuse.
Example: If an organization has a production cycle that requires 20 m3 of water per cycle, the organization withdraws 20 m3 of water for one production process cycle and reuses it for an additional three cycles, then the total volume of water recycled and reused for that process is 60 m3.
