Hello, I'm Velella. I wanted to let you know that one or more of your recent contributions to Anaerobic digestion have been undone because they appeared to be promotional. Advertising and using Wikipedia as a "soapbox" are against Wikipedia policy and not permitted; Wikipedia articles should be written objectively, using independent sources, and from a neutral perspective. Take a look at the welcome page to learn more about Wikipedia. Adding your research findings to many articles is considered citation spam. Please do not add your research findings to any more articles. Velella Velella Talk 11:33, 5 July 2019 (UTC)
