Patent number: 10519389Abstract: The present invention provides integrated bunker storage systems for waste streams based on the composition and characteristics of waste streams. In particular, the present invention provides a process for generating individual waste streams based on a set of material characteristics. According to the system and method of the present invention, individual waste streams from wastes stored in bunkers are mixed in a given feed ratio to generate a feed stock that will produce a desired output from a chemical conversion process, e.g., gasification. Optionally, composition data regarding the feed stock can be certified to a third party.Type: GrantFiled: June 21, 2017Date of Patent: December 31, 2019Assignee: Accordant Energy, LLCInventors: James W. Bohlig, Douglas R. Casella
