Method for manufacturing high value manure and useful by-products from grape stones which, separated by sieving from the cake after aerobic putrefaction, are open by crushing and subjected to a new aerobic putrefaction step. The components of the putrified crushed pips are divided in three fractions of different size particles by means of a sieve, of which the fine fraction contains exclusively, or almost exclusively, germs turned into humus and nutritive tissues turned into humus from the grape stones, the coarse fraction is comprised exclusively of grape stone husks divided into three and four parts and the medium fraction contains small pieces of husks. |
