3 The classical refuse economy already represents a simple form of material flow systems in agriculture. While the input materials in agricultural production are soil, fertilizer, seed, plant protection agents and fuel, the output materials are yield product and residual substances. The yield product can be sold or used but agricultural wastes can not be sold. It actually contains disposal and never used in production and is not valuable product tfor agricultural lenterprises. Therefore the classical waste management is not sustainable. Regional, ecological, social aspects are not evaluated in this perspective 3

4 Reserach of collaboration of different systems, in modern materialflow management systems the input and output materials were used dependent one from other, the waste of a sector can be used as input material of another sector. Thus the volume of wastes can be decreased and the income can be increased. 4

5 The definition and implementation of "Zero Emissions Strategies" for single industries, industrial clusters as well as entire cities or regions are playing a key role on the way towards a Circular Economy. The development of eco efficient products, services and technologies boost societies capability to create closed material loops and activate renewable energy potentials. All countries must implement new energy and resource efficiency strategies to ensure a competitive and sustainable economy, a Circular Economy. Circular Economy with MFM approach is shown in Figure. 5

6 6 The goals of the circular economy approach can be described as follows: Protection of the environment through the conservation of sources and sinks Reduction of dependence on resource suppliers Cost reductions in raw materials and energy provision Minimization of outflow of purchasing power Creation and retention of local l jobs Formation of networks Increased competitiveness Establishment of regional net product Conservation and stabilization of areas of unspoiled nature with particular consideration for the maintenance of cultural areas.

7 The environmental, economical and social benefits were constructed and the expectations from this study; Developmentl tof apilot biogas plant utilizing i various wastes for energy conversion, Energy production from a renewable energy source and contribution to the economy, Contribute to widespread manufacturing of biogas production technologies in the nation, Achievement and gaining of experiences on development of biogas production systems, Gaining of experience on integration of biogas with internal combustion engines and micro turbines, Rational use of resources and reduce the environmental damage caused by wastes, Contribution to the economy by utilizing fertilizers which are rich in nutritional values and is obtained as by-products from the biogas plant, Determining techno-economic criteria needed for enlargement of the systems for industrial use. 7

8 There are many factors which affects the integrated biogas and energy production. There are; Characteristics of the waste material, Design parameters of fermenters, Operational p parameters of fermenters, Parameters of energy conversion systems, Location features of the facilities. 8
