A simplified scheme of the environmental and economic system “coke and by-product process - the environment” was developed. The forms of the investigated environmental-economic interactions were visualized and the selective interpretation of the tightness of the established connection was made. The main result of the work is modeling system of environmental and economic interactions that allows increasing the efficiency of local ecological and economic system management and optimizing the “interests” of an industrial enterprise - the source of negative impact on the environment.
