Water
Optimizing the use and improving the quality of water in our operations.
Highlights
- Greif’s approach to water management stems from our responsibility to protect key resources for future generations. A critical piece of this approach is maintaining compliance with local and global water regulations that apply to our operations across the world.
- Our water management priorities focus on efficient and responsible water use in our mills and in water-scarce regions throughout our operations. We leverage standardized environmental data dashboards across our mills enabling us to effectively manage water use in our paper production processes.
- In 2024, we furthered our progress in water conservation initiatives. We eliminated direct discharges into local waterbodies from our Baltimore mill. In the future we continue to aim to reduce direct discharges at other facilities, with plans to phase out discharges at the Taylors mill by 2026.
- Our water conservation efforts contributed to a 10 percent decline in water withdrawal and a 2 percent decline in water discharges since 2019.
Why Water Matters
Greif prioritizes responsible management of our water resources, aiming to mitigate negative impacts associated with water withdrawals, discharges, and stormwater runoff. We recognize that water is a vital resource, and we strive to safeguard it for the benefit of future generations. Following The Greif Way, we seek opportunities to contribute to positive outcomes for the environment and for communities with whom we share a water source. To that end, we pursue opportunities to improve water efficiency and elevate water quality across our organization with a focus on water-intensive operations at our mills. In efforts to comply with water quality requirements, water discharged from our facilities undergoes thorough treatment, whether on site or by a trusted third party. All treatment measures strictly adhere to relevant regulations so that the discharged water meets high standards of health and safety for wildlife and the local communities.
Our Approach
Our commitment to global water conservation and efficiency is outlined in our Environmental, Health and Safety (EHS) Policy. We enlist our EHS team to monitor regulatory compliance and implement optimal practices in water treatment and recycling across all facilities. The EHS team also proactively oversees water usage in critical facilities, including those in water-stressed areas to help optimize our water footprint. Within our environmental structure, we maintain a robust compliance management system with dedicated support. Greif champions and empowers local management teams to improve water efficiency, enhance water quality, minimize impact on local water sources, and reduce associated costs. Our approach extends to managing water discharge in strict compliance with individually allocated water permits.
We recognize water is a critical element of the manufacturing processes at our mills and understand the impacts irresponsible water consumption can have on local communities and ecosystems. To support sustainable water usage at Greif, we have worked diligently to deploy advanced water management practices at paperboard mills within our Sustainable Fiber Solutions business, which accounts for approximately 90 percent of our total water usage. At these sites, we have implemented reduction and recycling processes including collecting HVAC cooling water and compressor cooling water for reuse at our Riverville mill, installing ultra-low water consumption mechanical seals on process pumps at our Massillon mill, and installing effluent treatment plants at multiple mills that not only reduce biochemical oxygen demand but also reduce water consumption overall. We plan to evaluate sustainable water management practices moving forward with ambitions to reduce non-contact cooling water discharges at our paper mills.

Effective management of untreated stormwater is central to Greif’s water strategy, upholding our ambitions to protect local water resources. To carry out this approach, we place a strong emphasis on effective stormwater management practices across our plastic and steel facilities. Regular and thorough stormwater sampling and testing are essential parts of our operations, maintaining strict adherence to safety standards and regulations while identifying continuous improvement opportunities. We provide comprehensive annual training to all relevant colleagues to help build a culture of responsible water management throughout our organization.
Preventing and responding to unforeseen water events like spills are crucial aspects of our approach to water management. In addition to site-specific stormwater pollution prevention plans and robust spill prevention controls at our key facilities, we have comprehensive global contingency plans and emergency procedures designed to address and mitigate any potential or actual spills. Our operations emphasize compliance, utilizing our Environmental Management System (EMS) to track spills or releases that may impact groundwater and soil and identify corrective actions to remediate such events. We are currently evaluating potential improvements to the EMS to capture additional quantitative data to track trends over time and improve our incident response efforts.
An essential aspect of our approach to water management is compliance with emerging water-related regulations. By adopting sustainable water practices, we can minimize potential sources of noncompliance related to water management while simultaneously improving operational efficiency. Responsible water management also drives the mitigation of risks that pose a threat to Greif’s daily operations and long-term business success, specifically in water-stressed regions where we operate. Annually, we use the World Resources Institute’s Aqueduct Water Risk Atlas tool to consider which of our facilities operate in areas of water stress. To mitigate negative impacts in these regions, we have adopted policies and practices designed to reduce excess water consumption such as replacing faulty valves, promoting water recycling, installing touchless faucets and harvesting rainwater. Greif recognizes that operating responsibly within water permit requirements at every facility is critical to accomplishing our mission of securing water sources for future generations.
Goals, Progress, & Performance
2025 Goal:
- Reduce biochemical oxygen demand discharged in kilograms by 10 percent per metric ton of production from Riverville and Massillon mills using a 2014 baseline by the end of FY25.
As of the end of 2024, we have reduced the biochemical oxygen demand by 67.6 percent from our 2014 target baseline of 1.40.
Most of our water consumption occurs at our paperboard mills, where we reuse water several times before treatment and discharge. Our mills account for approximately 90 percent of our global water usage.
In 2022, we utilized a third-party consultant to assess the water usage at our paperboard mills. This comprehensive study developed water models for each of our mills, unveiling new opportunities for minimizing water consumption. In 2023, we identified three projects with specific actionable items to reduce water use at our mills, and they are currently being evaluated for implementation over the next two years.
Greif utilizes key performance indicators to monitor water usage and wastewater treatment. We continuously streamline our environmental data dashboards across our facilities to develop a more comprehensive understanding and effective management of our water, effluents, and energy data. Improvements in this area enable us to consistently discover and leverage water efficiency opportunities. Please see our report’s Environmental Management Systems section for more information about our evolving approach to environmental data oversight.
Practicing Circular Economy
At Greif’s Austell mill in Georgia, we began a wastewater residuals dewatering project to turn waste into biofuel. The circular economy practice sweeps thickened solids from a floating sediment blanket on to a dewatering press. The flowable solids are dehydrated until they can be transported to a location to air dry, mixed with other materials, and consumed as a supplemental boiler fuel. This process not only allows materials to be repurposed to gain the most benefit from start to finish, but it also saves the facility landfill disposal fees.
Water Reduction at Our Florence, Kentucky Mill
In late 2019, Greif’s Florence, Kentucky facility installed a wastewater treatment facility to reduce our hazardous waste load and recycle water back to the city. The process works by introducing water into the system, removing close to 100% of the pollutants from the paint process and sends the cleaned water to the local treatment plant. The water is then recycled by the treatment plant for redistribution to the community. The material leftover from the process is disposed via trash instead of hazardous waste. As the equipment came fully online in mid-2020, the process has not only significantly lowered hazardous waste generated by the facility, but also reduced the cost of waste by $40,000 a month.
