The tea that driops out in the process of both cleaning the dung and draining off the briquette during compression is very useful as fertiliser at the same time.

A couple of points about this: if simply washing out the dissolved
minerals leaves a suitable residue which can be bound in a briquette
why cannot an AD plant do the work for you first? Not that I'm
suggesting building an AD plant but rather that the fibrous waste from
this may be used. After all doesn't an AD plant mimic a rumen?

The other is Anand's statement that ruminant dung is largely lignin,
presumably this depends on how good the rumination has been because in
UK there was a firm that collected sheep dung and washed it to
retrieve fibres which they then used to make high quality paper, which
suggests there was a deal of cellulose left in the dung.
