As we mentioned during the GG18 round, Oxygenchain has collaborated with pioneering leaders in the water treatment and recycling sector in Portugal which resulted in the successful development and installation of an oxygen-ready water treatment and recycling system for car washes and gas stations, contributing to effective waste treatment and water conservation.

Since then we have concluded the installation of Oxygenchain’s inaugural residential participant at Gardens apartments in Rio de Janeiro, marking a significant milestone. While industrial waste is a grave concern, the residential segment is equally pivotal. Global statistics by PhD researcher Edward Jones notes that about 359 billion cubic meters of wastewater, equivalent to 144 million Olympic-sized swimming pools, are produced annually, half of which remais untreated. Shockingly, one in three housing units in Brazil lacks sewage treatment.
In the United States, the EPA has introduced flexibility for cities, permitting delayed or altered federally mandated fixes to sewer systems, which contributes to continued sewage dumping into rivers. Oxygenchain recognizes these critical issues and remains committed to addressing them.

To enhance our efficiency and streamline system setup, we have initiated the development of an onboarding app. Currently, the manual setup process requires the installation of sensors, PLC, oxygen nodes, and further component configurations. Our aim is to automate and simplify this, reducing the manual work associated with node setup, thus facilitating easier adoption as well as positioning Oxygenchain among apps focusing on data accuracy, reliability, and transparency—integral aspects of blockchain-enabled applications. This categorization aligns with our commitment to providing trusted and verifiable data for water treatment systems, facilitating easier access for users seeking solutions in data measurement, reporting, and verification. It emphasizes our dedication to leveraging technology for environmental stewardship and operational efficiency.
