格雷夫 环境健康与安全 (EHS) 政策 provides global guidelines for water conservation to improve water efficiencies in existing operations and incorporate water management in planning for future projects and technology investments. Each Greif facility is expected to manage water locally in accordance with our EHS policy with supervision and support from Greif’s EHS team regarding compliance obligations and best practices for water use, treatment, and recycling. Local management teams are encouraged to improve water efficiencies and quality, reduce water withdrawal to minimize impact to local sources, maintain regulatory compliance and reduce costs related to water. 95 percent of Greif’s water use impact occurs in our 13 paperboard mills within our Paper Packaging and Services (PPS) business. Our water management efforts primarily focus on these mills. In 2020, we continued our efforts to eliminate direct discharge from our mills by converting our Baltimore, Ohio mill to discharging to a local municipal water treatment plant. In addition to removing direct discharge from our operations, this transition reduces Greif’s overall water withdrawal by 400,000 gallons a day. Many of these mills draw on well water from local aquifers, which in turn are discharged into different bodies of water post-use after treatment. We have also continued to implement projects to reduce water use in our mills. For example, at our mill in Los Angeles we replaced nine water oscillators with electromechanical oscillators which reduced well water intake by 2.1 million gallons per year, a 4 percent reduction, in addition to reducing our costs.
