ReTo Eco-Solutions, Inc. provided updates for its joint R&D demonstration in the Beijing Winter Olympics' national key project (the "Project"), which is the result of the collaborative efforts with the Academy of Arts & Design at China's Tsinghua University. The R&D team has designed and developed a 3D printer using solid industrial waste, and the printer has been assembled and tested. The R&D team has also conducted a formula research on the utilization of the solid industrial waste, enabling the product to enter trial stage. The Project (i.e., the ground pavement system) will be used in the high-traffic Shougang area in preparation for the upcoming 2022 Winter Olympics in Beijing. As previously disclosed through a press release on January 28, 2021, ReTo has been working with the Academy of Arts & Design at Tsinghua University on this latest high-profile, national priority research and development Project. The Project features many advanced technology applications in the fields of solid waste utilization, 3D printing, solar energy utilization, energy storage and luminescent materials. As a national priority scientific research project, it will be the key to the Shougang Park, which will be the main venue of the Beijing Winter Olympics and where a series of key events will be held. Under the project plan, ReTo will develop the technology, equipment and aforementioned special materials, and necessary facilities in the park, while the Company provides continuous maintenance and management of this eco-friendly solution.
