The document discusses garbage in cities using a Pareto diagram. It analyzes garbage data from Mumbai and finds that the top 5 types of garbage - paper, food scraps, yard trimmings, plastic, and metal - make up 80% of the total garbage. It then provides a problem statement for each of these top 5 garbage types, discussing the environmental and other issues they cause and possible solutions. The team learned about the benefits of Pareto diagrams for analyzing processes and the importance of properly managing different types of garbage to improve city conditions.
