Cordless Battery-Powered Tools in Urban Construction: Environmental and Operational Impacts in Brazil

The transition from corded to cordless power tools in urban construction sites presents both environmental challenges and operational benefits. This study investigates life cycle impacts, safety improvements, and energy consumption patterns associated with battery-powered tools in São Paulo, Brazil. Using the MECO (Materials, Energy, Consumption, Others) matrix and field data from 12 construction sites, we compare the performance and sustainability of cordless versus corded equipment. Results indicate a 23% reduction in workplace accidents and improved ergonomics with cordless tools, despite higher material complexity and shorter battery lifespans. We conclude that cordless tools, when integrated with renewable energy sources and circular battery management, offer a viable path toward cleaner construction practices.
