This work describes a current problem of modern society – the inefficient use of resources due to insufficient exchange of things between people. The focus is on the need to create a software system to facilitate this process. This work justifies the need for this system due to the increase in consumption and waste, which has a negative impact on the environment. The software system offers an effective mechanism for sharing things between users to reduce waste and encourage a culture of resource use. The report also discusses the possible benefits to society, such as cost savings, promotion of resource recovery and support for social mutual assistance. It highlights the key features and benefits of the proposed software system aimed at optimizing the exchange of things and preserving the environment.
