Dear Rajan, Transporting the wet slurry from a dung based biogas plant to the field is always a bother. One can allow the slurry to be filtered through a bed of straw. The water in the slurry drains out, leaving the relatively dryer slurry on the surface of the bed of straw. The slurry, now devoid of most of its water is easier to handle and to transport # OK!! Do you think it might be possible to briquette the drained anaerobic residue ands a fuel or pellet? Does such residue have greater as an agricultural supplement than as a potential fuel?

Here the energy part comes out as methane ( which is used as fuel ) and the slurry from the plant contains all the nutrients ( without any loss ). I have no experience with biogas plants run on animal manure. Is the slurry from a biogas plant filterable? If so, would it potentially make a fuel equivalent or superior to dung that was burned directly, with no washing? As I understand it, Richard Stanley uses a retting process on biomass, to develop binding characteristics for his holey briquette feed. Would the drained solids from a biodigester perhaps have better "binder characteristics than freshly washed dung? Perhaps Righard has already explored this avenue?
