In collaboration with the local government, AoBag Environmental, a waste classification company, successfully implemented a rural waste management system in Liuba County, Shaanxi. Utilizing a bag-based model with QR codes, they encouraged residents to recycle, provided incentives through a mobile app, and tackled challenges of rural operations. The innovative self-service collection points, designed with durability and efficiency, contributed to a zero-landfill and zero-waste goal. Over three years, they covered 59 villages, achieving significant recyclable material recovery and environmental preservation in the Qinling region. 汪剑超，前微软中国研发工程师，在2011年转向垃圾分类与资源化创业，被媒体称为“捡破烂的微软工程师”。他2012年设计的“二维码+积分兑换”模式成为中国多数城市垃圾分类的参考。2017年初，创立奥北环保，提出了“满袋换空袋、满桶换空桶”的分类新模式。他曾两次登上一席分享，也入选了盖茨基金会和联合国2017 Global Goalkeepers，以及2020迪拜世博会中国唯一入选的创新项目。 This talk was given at a TEDx event using the TED conference format but independently organized by a local community.
