【 摘 要 】

Biogas is an important type of biofuel obtained from renewable energy sources. It can be produced from urban or industrial waste and also by decomposition of organic or animal residues. For this reason, the quantity of researches and publications about biogas had a rapid growth in the last decades. Additionally, the number of articles written in co-authorship has increased significantly. In this way, this work built the scientific collaboration network about biogas in a period of 65 years, i.e., 1945-2010. Papers were recovered from the Web of Knowledge database of the Institute for Scientific Information (ISI). Queries were made looking for the biogas name in the paper title. Thus, three networks were constructed: authors, institutions and countries. In the period studied, 1238 papers were analyzed. These documents were published by 2852 different authors in 1000 distinct institutions belonging to 89 countries. The top five countries were India, Germany, The United States of America, China, and Denmark, respectively. An interesting observation is that around 85% of the publications had at least one type of co-authorship between authors, institutions or countries.
