Por que a água é importante
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
Nosso compromisso com a conservação e eficiência global da água está descrito em nosso Política Ambiental, de Saúde e Segurança (EHS). 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
Meta para 2025:
- Reduzir a demanda bioquímica de oxigênio descarregada em quilogramas em 10% por tonelada métrica de produção das fábricas de Riverville e Massillon usando uma linha de base de 2014 até o final do ano fiscal de 25.
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.
A maior parte do nosso consumo de água ocorre em nossas fábricas de papelão, onde reutilizamos a água várias vezes antes do tratamento e da descarga. Nossas fábricas respondem por aproximadamente 90 por cento do nosso uso global de água.
Em 2022, utilizamos um consultor terceirizado para avaliar o uso de água em nossas fábricas de papelão. Este estudo abrangente desenvolveu modelos de água para cada uma de nossas fábricas, revelando novas oportunidades para minimizar o consumo de água. Em 2023, identificamos três projetos com itens acionáveis específicos para reduzir o uso de água em nossas fábricas, e eles estão atualmente sendo avaliados para implementação nos próximos dois anos.
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 Sistemas de Gestão Ambiental section for more information about our evolving approach to environmental data oversight.
Praticando a Economia Circular
Na fábrica Austell da Greif na Geórgia, iniciamos um projeto de desidratação de resíduos de águas residuais para transformar resíduos em biocombustível. A prática da economia circular varre sólidos espessados de uma manta de sedimentos flutuante para uma prensa de desidratação. Os sólidos fluidos são desidratados até que possam ser transportados para um local para secar ao ar, misturados com outros materiais e consumidos como combustível suplementar para caldeira. Esse processo não apenas permite que os materiais sejam reaproveitados para obter o máximo benefício do início ao fim, mas também economiza as taxas de descarte de aterro sanitário da instalação.
Redução de água em nossa fábrica em Florence, Kentucky
No final de 2019, a instalação da Greif em Florence, Kentucky, instalou uma estação de tratamento de águas residuais para reduzir nossa carga de resíduos perigosos e reciclar a água de volta para a cidade. O processo funciona introduzindo água no sistema, removendo cerca de 100% dos poluentes do processo de pintura e enviando a água limpa para a estação de tratamento local. A água é então reciclada pela estação de tratamento para redistribuição para a comunidade. O material restante do processo é descartado no lixo em vez de resíduos perigosos. Como o equipamento entrou totalmente em operação em meados de 2020, o processo não apenas reduziu significativamente os resíduos perigosos gerados pela instalação, mas também reduziu o custo dos resíduos em $40.000 por mês.
