Abstract

In addition to energy production from the biogas plants, which are among renewable energy technologies, biogas digestate is also produced. The scientific studies related to this product have increased especially since 2000, and continue to increase. These studies show that the usage area of biogas digestate is quite wide, and it is a valuable product. According to these studies, biogas digestate is a product that can be used in plant nutrition, animal feed, obtaining irrigation water, bio-pesticide, seed pre-treatment, phosphate salt, and carbon synthesis. When the studies are examined, it is seen that biogas digestate is a product that can compete with limited fossil resources. However, it was seen that more scientific studies should be done about risk factors, environmental effects, fertilizer treatment methods and enrichment in the long-term applications.
