Purpose: This article aims to present the theoretical solution to the problem of waste management. Design/methodology/approach: This model is a proposal for the assessment of bids, which enables the unification of assessments against the criteria expressed in various measures, includes determining the importance of individual criteria, and thus the simulation of assessments when changing the criteria weight values. Findings: The article presents the theoretical optimization model of waste collection and management, which may be helpful in solving the problem of waste more effectively. Research limitations/implications: The article is limited to presenting only the basic model of waste management optimization. Due to the fact that in individual administrative units of the country solving the problem of waste is a local issue, it was impossible to present a solution that would be adequate for each region of the country. Practical implications: The article presents a theoretical model that can form the basis of a practical optimal solution to the problem of waste in individual administrative units of the country. Social implications: Optimal waste management is an extremely important social issue. In addition to efficient waste management, increasing public awareness of the impact of precipitation segregation and recycling on the environment is an extremely important issue. Originality/value The presented model is a flexible model that can be used by individual administrative units, taking into account the specificities of waste management possibilities and restrictions in a given region.
