The Circular Drive Initiative (CDI) is a collaboration of global leaders in digital storage, data centers, sustainability, and blockchain in a joint effort to reduce e-waste by promoting and enabling the secure reuse of storage hardware. CDI was convened under the leadership of William McDonough, Chief Executive of McDonough Innovation and the renowned architect of Cradle to Cradle design and The Circular Economy, which brings circular design principles and reporting to data storage in the ICT industry. The ultimate goal is to facilitate the reuse of storage devices and reduce GHG emissions, e-waste, and other externalities.
