Our second-life battery systems can be aggregated into virtual power plants (VPPs) that participate in energy markets, providing valuable grid services and creating new income streams for your organization.
Carbon Footprint Reduction
Our operations prevent 150,000 tons of CO2 equivalent emissions annually by diverting materials from landfills and reducing the need for virgin material extraction. Each ton of e-waste processed saves approximately 3 tons of CO2 emissions.
Water Conservation
Advanced closed-loop water systems in our facilities reduce consumption by 80% compared to traditional recycling methods. We've eliminated over 2 million gallons of wastewater discharge annually through innovative treatment and reuse technologies.
Clean Energy Integration
All Rienu facilities operate on 100% renewable energy, with on-site solar installations providing 60% of our power needs. Our second-life battery systems store excess renewable energy, supporting grid stability and clean energy adoption.
