Consolidator: TUBITAK, The Scientific and Technological Research Council of Turkey
Project No: 114M142
Start/Due Date: 01.11.2014/01.11.2016 (Ongoing)
Nowadays, there are incredible changes in supply-demand balances of energy production by means of energy production from waste and using renewable energy sources. The strategies based on the development of sustainable waste sources and energy recovery are consisted of production, collection, usage and final elimination stages. Adverse effects taken place on the environment during the life cycle of these stages can be eliminated by means of recycling technologies. The importance of waste recycling and elimination facilities is well understood in the case of approaching to the waste as both pollution and energy-raw material source. The necessity for the management of waste which creates main environmental concerns has caused the development of various types of waste management systems, worldwide. The main aim of the studies being made on elimination of wastes is to be able to choose the best method which has the least cost and risk to both human being and environment. The basic waste management strategies can be classified as waste elimination, energy recovery, recycling, waste minimization or avoiding, and zero waste approach.
Zero waste approach is based on reassessment of wastes and in this way, minimization of damage of wastes on the environment by increasing energy recovery potential of current systems. The first step of zero waste management is to be able to figure out all waste constituents in waste elimination facility and also how to eliminate these wastes in order to perform an adequate environmental management. The second step is to integrate the appropriate proposed energy recovery models to current systems according to the present waste elimination techniques. At last step, recovered energy is provided for usage in waste storage plants and/or in energy dense sectors. Zero waste approach can be evaluated as a management style which provides a favorable cost gain with low payback period and increases the current operational efficiency of the facility in long term.
In this project, first, thermodynamic and thermoeconomic analyses and optimization of Gaziantep Metropolitan Municipality Solid Waste Storage, Biogas and Cogeneration Plant will be performed using its operational and economic data. Then, energy recovery models in the frame of zero waste approach will be proposed using available waste heat sources of the current plant. After the detailed simulation studies of the proposed models, a comparative thermodynamic and thermoeconomic analyses and optimization will be done. The main aim of this study is to be able to figure out a sustainable and environmentally friendly waste management policy which can be applied to all solid waste storage, biogas and cogeneration plants in Turkey, by determining the optimum energy recovery strategies that can be integrated to current facilities. In the scope of the proposed models, increasing the energy recovery potentials of current solid waste storage facilities and reducing the environmental emissions are aimed to contribute to health of both human and environment by means of a rational zero waste management strategy.
In accordance with the modeling, analyses and assessments to be performed in this study, the energy recovery potential from solid waste in Turkey will be presented; the place and importance of energy from waste among other renewable energy sources will be emphasized; and lastly, a rational strategy will be developed by means of the proposed models in order to apply zero waste approach to current facilities.
