Tom's Guide took a trip to Lenovo's US HQ to tour their design labs and go hands-on with some of the company's latest computers, including the new Lenovo ThinkPad Z13 Gen 2. br ThinkPad features a flaxseed cover and majority recycled aluminum frame. Plus, plastic-free packaging made of bamboo and sugarcane makes this one of the most sustainability-minded laptops we've ever seen. br br But that's not all. At the offices, we also saw some of the sustainable materials Lenovo is testing, from post-consumer plastics to the discarded carbon fiber from airplane fuselages. We checked out how Lenovo is implementing water-cooling in data centers, too.
