The R2/RIOS certification is solely for electronics recyclers to demonstrate to customers that electronics equipment is being recycled with the highest standards for environmental protection, worker health and safety, and data privacy, and facility security. R2/RIOS is a combination of the Responsible Recycling (R2) Practices and the Recycling Industry Operating Standard? (RIOS). R2 was developed by a broad-based cooperative of electronics recycling stakeholders that included the U.S. Environmental Protection Agency (EPA), state governments, manufacturers, recyclers, trade groups and non-governmental organizations. RIOS is the sole program on the market that combines quality, environmental, health and safety requirements in a single management system.
