The aim of researches described in the dissertation is to analyze landfill site management conception for energy efficient usage of climate technologies, in order to reduce greenhouse gas emissions by reducing electricity consumption for leachate treatment and appropriate use of the biogas formed in landfill storage. In this work the renewable energy resources use optimization model is developed and it covers both horizontal and vertical modular systems. The optimization criteria are selected. Waste management energy resource optimization model is approbated for Daibe landfill conditions. The energy consumption for leachate treatment is analyzed and empiric model for specificē energy consumption of leachate treatment is obtained based on ongoing process in landfill and on analyze of leachate treatment technological equipment performance, and independent parameters are determined.
