CLIMATE CHANGE MITIGATION TECHNOLOGIES RELATED TO WASTEWATER TREATMENT OR WASTE MANAGEMENT

Description

Y02W covers technologies and processes designed to reduce greenhouse gas emissions or improve resource efficiency in wastewater treatment and waste management systems. This includes innovations in treatment methods, waste-to-energy conversion, circular economy approaches, and management practices that lower the carbon footprint of these operations. The classification encompasses both end-of-pipe solutions and preventive measures across municipal, industrial, and agricultural wastewater contexts, as well as solid waste handling systems. Y02W serves as a cross-sectional tagging mechanism to identify climate-relevant inventions in waste-related fields, complementing more technical classifications elsewhere in the IPC/CPC system.
