Due to the improvements in medicine and feeding opportunities, the average life expectancy of people has increased and the population growth rate has exploded. The world population exceeds 7 billion. The doubling time of population is also shorter. These developments in the population have raised concerns about the relationship between population and nutrition. Scientists are concerned about the danger of hunger. There are two remedies for this. First is to control the rate of population growth and second is to increase agricultural productivity. Agriculture also has other vital functions, not only to provide people with nutrients, but also to feed animals, provide raw materials for industry, employment and reduce dependence on other countries. Countries are working hard to increase the yield from the unit area in their agricultural land and applying some methods such as irrigation, pest control, seed breeding, fertilizing more than one crop per year. Fertilization is one of the important methods of increasing agricultural productivity. While fertilization is increasing agricultural productivity, used fertilizers cause environmenta lproblems such as soil and water pollution. Fertilizers also cause a significant cost for farmers. At this point organic fertilizer is an important alternative. Gönen Biogas Plants, established in Gönen in 2014, evaluates many wastes in Gönen and its surroundings and converts them into biomass energy. As a result this process, 15 thousand tons of dry fertilizer, 10 thousand tons of manureand 10 thousand tons of humic are produced annually. With the use of organic fertilizers obtained as a result of the elimination of environmental pollutants in agriculture, environmental pollution caused by chemical fertilizers is prevented.Also agricultural productivity is being increased. The facility provides 75% of its annual turn over from organic fertilizer production and marketing activities.
