The book "Mathematical Modeling and Simulation" by Thakaa Abd Saleh provides a comprehensive analysis of the challenges in municipal waste management, particularly concerning the city of Baghdad. It highlights the dangers posed by improper waste disposal and emphasizes the importance of converting biodegradable waste into valuable resources. By applying mathematical models and simulations, the book examines how the amount of solid waste in urban areas can be estimated, using population data from Baghdad as a central factor. It offers valuable insights into sustainable recycling methods, especially composting, and discusses the need to develop appropriate waste disposal procedures to minimize environmental impact.
