In January 2025, Mananalu relaunched as Mananalu Powered by Boomerang Water to implement on-site bottling systems. The initiative focuses on reducing imported water reliance across Hawaii by installing machines in local hotels.
Why it matters
The system aims to eliminate the environmental impact of single-use plastic bottles while reducing dependence on imported water shipments. By processing water locally, the company targets a significant reduction in shipping-related carbon emissions.
The system processes 400 to 500 bottles per hour, amounting to 4,000 units daily, while achieving a 95 percent reduction in carbon emissions. To date, the company has removed 6 million plastic bottles from the ocean.
