I just sent an inquiry to New England Biochar. The metal Adam retorts he sells seem to be what I am looking for because they are mobile, apparently extract wood vinegar and tar, and meet United States standards. I looked through all the links and most of them had blank links or something or they did not sell machines themselves. The University of Washington research is fantastic. Of course you could research biochar until you are blue in the face but I just want to get a machine soon and not spend all my time fooling around in a yard. I found what seems like the machine I saw in the video on Alibaba, but I will be sending the farm in Japan an inquiry about their machine. It will depend on the price difference and efficiency assuming I get a lead on the Japanese model. The price on the machine I found on Alibaba is not clear, so I am sending an email to them too, but imagine the transport costs will be extreme. New England biochar has a teacher come set up the system so that will probably make me go with them.
Any thoughts on funding an Adam retort? Could I do some kind of co-op with it? What would the market be for selling wood tar and wood vinegar to farms and such?
