STIHL Effluent Reuse
ABOUT IT
O STIHL Effluent Reuse Project, installed at the factory of São Leopoldo (RS), its main objective to reduce the dependence of the production process on the public supply of drinking water., optimizing the use of natural resources and reducing operational costs.
The studies began in 2019, and the project represented a R$ investment 4 million. The system implemented treats the industrial effluents generated in the unit's operations, allowing for... minimum reuse of 50% of the treated volume, which is equivalent to more than 51,000 m³ of water recovered per year.
Reclaimed water is used in critical processes, such as Chrome plating of parts, gas scrubbing, and cooling towers., in a continuous cycle of treatment and reuse. The system includes Cascade recirculation, bath optimization, ion exchange filtration, and operator awareness..
Aligned with UN Sustainable Development Goals (SDGs), The project reinforces STIHL's commitment to modernize its infrastructure, increase water use efficiency, and reduce waste generation., contributing to resilience in the face of climate change.
Results and Objectives
Project Objectives
• Reduce the consumption of drinking water and dependence on the public water supply system.
• To increase the water efficiency of industrial processes, especially in critical sectors such as chrome plating.
• To treat and reuse industrial wastewater, transforming it into water of suitable quality for the production process.
• Reduce the volume of wastewater released into the environment.
• To raise employee awareness about the rational use of water.
• To contribute to SDGs 6 (Clean Water and Sanitation) and 12 (Responsible Consumption and Production).
Results and Impacts
Environmental:
• Minimum reduction of 50% in the discharge of treated effluents to the environment.
• Decrease of 32% in drinking water consumption.
• Annual reuse of 51,474 m³ of treated wastewater, equivalent to the consumption of 350 residences.
• Reduction of 37% in the volume of chemical products used in water treatment.
Economic:
• Estimated annual savings in R$ 1.2 million including water and treatment costs.
• Greater operational stability and less dependence on variations in public supply.
Social:
• Contribution to the local community water security, by reducing pressure on the public water supply system, especially during periods of drought.
• Strengthening the internal culture of sustainability and environmental responsibility.
