Sustainable Products, Projects and Green Design Packzero Reusable Package by Yanhui Ban, Ruoyi An, Shijie Luan PackZero proposes to transform the current resource depleting online retail distribution system, with a circular delivery network that combines inflatable reusable packaging with hybrid pickup and delivery experience. Central hubs at locations that users frequent or find easily accessible will be built, thereby reducing overall 'product miles.' The reusable package is made of durable biodegradable material, which research estimates can be potentially used up to 100 times.
