MATERIALS AND METHODS

Near the situated experimental system to the inside of the realized Technological Platform
from META S.p.A. of Modena to Limidi di Soliera they have been conduct the greater part of the tests; in particular they have been dealt: the obtained solid fraction for such centrifugalization of liquami suini which; the obtained solid fraction for nastropressatura of mud of business biological depurazione of liquami suinicoli and mud of consortile biological depurazione of liquami suini, bovines and civilians; the deiezioni of ovaiole hens (pollina). The various palabili materials have been dealt in mixture with two tipologie of
lignocellulosici refuse: business refuse (straw and stocchi of maize), added in variable
amount from 10 to 20% of the weight of the solid fraction and extra-business refuse
(prunings of the green public crushed) added in variable amounts from the 20 to 40% of the weight of the solid fraction. Only the pollina has been started on such treatment also which. The adopted techniques of production have been two: compostaggio in reactor
closed to fossa horizontal (7 theses) with frequent rivoltamento and compostaggio in
cumulus on platea covered with rivoltamento weekly magazine with rubberizing shovel or small rivoltatrice (4 theses). The compost obtained they are the result of a treatment of articulated compostaggio therefore: the bioossidativa phase of the process has had a
variable duration from the 45 to the 60 days (during which they have been carried out the rivoltamenti). The successive maturation has happened in cumulus (rivoltato periodically), when possible under shed, for a variable period from the 30 to the 120 days. Altogether the compostaggio cycle has turned out variable from 3 to 6 months.
