Return-Loads Bureaus to Save Waste in Transportation is a comprehensive treatise authored by the Committee on Elimination of Waste in Transportation of the Federated American Engineering Societies. Published in 1921, this book delves into the inefficiencies and economic losses caused by empty return trips in freight transportation across the United States. Drawing on extensive research, case studies, and statistical data, the book highlights the magnitude of waste resulting from uncoordinated shipping practices, where vehicles often return to their origin without carrying cargo. The book proposes the establishment of Return-Loads Bureaus-centralized agencies designed to match available transport capacity with shipping needs, thereby minimizing empty hauls and optimizing the use of transportation resources. It outlines the operational framework for such bureaus, including methods for collecting and disseminating information, coordinating between shippers and carriers, and leveraging telecommunication and record-keeping systems of the era. The text also discusses the economic, environmental, and social benefits of reducing waste in transportation, such as lower freight costs, reduced fuel consumption, and improved efficiency in supply chains. Through detailed analysis and practical recommendations, Return-Loads Bureaus to Save Waste in Transportation serves as both a historical document and a forward-thinking guide for policymakers, industry leaders, and engineers interested in logistics, transportation management, and the broader movement to eliminate industrial waste. The book stands as a testament to early 20th-century efforts to address systemic inefficiencies and remains relevant to contemporary discussions on sustainable transportation and resource optimization.
