Mathematical model of economics of municipal waste management

The paper discusses the mathematical and economical model of municipal integrated waste management system (IWMS) that has been developed for the real needs of the decision support of the Ministry of Environment of the Czech Republic and regional governments. The model of IWMS is designed as universal and is implemented as a combination of three models including environmental and economic point of view. The model allows evaluation of the economic and productive efficiency of the system due to own setting of input values and can be used for waste management planning as a decision support tool. Model involves composting, energy and material recovery of waste and landfilling. Its size (number of sources and facilities) depends only upon available data. The model was developed based on given input macroeconomic variables and it enables to inclusion or exclusion of certain equipment of waste management and the capacity of the equipment. It uses data from annual reports of municipalities (if available) on the production of municipal solid waste and estimates its quantity (if unavailable) by using a sophisticated model, including demographic and socioeconomic impacts. The important component of the paper is economic model of the IWMS functions.
