Hello Keith, Thanks for the info. And please let me know how your experiment goes this winter.

Re: [Biofuel] Methane Digester
it is best to start small. Methane production does not affect the amount of compost you can make. After the effluent has passed through the digester, it goes to the compost pile. JTF has some really fantastic information on Methane digesters.

Hi Tim, Over in Ireland here we use approx 200head cattle as break even point, depends if you are selling back to grid, and have use for heat (CHP) Are you in Europe, check CADDETT for more info of technology suppliers, best of luck with project, Sh*t Happens. dD [EMAIL PROTECTED] wrote: I was curious to know if anyone has any first hand experience with Methane Digesters.
