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.

除了可再生能源技术中沼气厂的能源生产外，还生产沼气消化液。自2000年以来，与此产品相关的科学研究特别是增加了，并且还在继续增加。这些研究表明，沼气消化液的使用范围很广，是一种有价值的产品。根据这些研究，沼气消化液可用于植物营养，动物饲料，获得灌溉用水，生物农药，种子预处理，磷酸盐和碳合成。当检查研究时，可以看到沼气消化物是可以与有限的化石资源竞争的产品。但是，人们发现应该对危险因素，环境影响，
