A zero-waste factory refers to a factory that, during the production process, minimizes the generation of waste as much as possible, and then implements measures such as classification, recycling, and reutilization of the generated waste, achieving zero waste discharge. 

Six major pain points: Lack of a digital carbon-integrated smart platform for control, low proportion of new energy power consumption, inadequate energy management of industrial equipment, lack of carbon reduction technologies, insufficient awareness of carbon investigation, carbon footprint, and carbon management, and an incomplete waste recycling system. 

2. Construction path: Establish a control platform, enhance the utilization of new energy, carry out equipment upgrades, adopt carbon reduction technologies, renovate green buildings, and build a waste recycling system.
