Re: Digesting crude biodiesel glycerol

hummmm.
Well im about to build a test rig, with a 20l container - so it would be a batch container.
I have access to raw glryc, cow waste, grass cuttings and human waste.
I was going to put 5 litres of raw glyrc in the mix and see where it went from there? or do you suggest more or less?

Re: Homebuild digester and the pitfalls..

I heard some commentary on the radio today about someone who claims that when paper is anaerobically digested it produces 4 times its paper weight in methane gas.. Is there any truth to this? Would you recommend putting shredded paper into an anaerobic digester?

Re: Homebuild digester and the pitfalls..

wow, I dont presently have the ability to measure gas production. But that is very impressive. What are your recommendations and 'recipe' guidelines? While I was traveling round Thailand, I went to see a project where a farmer is using the dung from his buffalo to feed the digester, he had more than...

Re: Homebuild digester and the pitfalls..

Hi Bob, I think thats a fantastic idea - starting small to get an idea of the process involved.
