PROVISIONAL SPECIFICATION.
Treatment of Moss Litter Manure for Obtaining Products
therefrom.
I, EDWARD VAN DE GRIENDT of Westerkade, Rotterdam, in the Kingdom of
Holland, Managing Director of the Griendtsveen Moss Litter Company Limited,
do hereby declare the nature of this invention to be as follows:-
This invention relates to the treatment of moss litter that has been used for
stable purposes in order to recover theréfrom salts and to render the litter suitable
for fuel.
For this purpose the spent moss litter is treated for several hours in a boiler with
steam, the mass being kept thoroughly agitated by means of a screw or other
suitable means.
The steam passing from the vessel is allowed to percolate through sulphuric acid
whereby the ammouia is recovered in the form of sulphate of ammonia. After the
mass bas been treated for a sufficient length of time the liquid portion is run off*
and evaporated in open vessels, with the result that the salts left are found to
consist of a mixture of nitrates, phosphoric acid and alkali which can be used as a
manure.
The mass left in the boiler is then treated in centrifugal machines or by
other known means so as to thoroughly dry same, when it can be used as fuel.

claim is:-
A process for treating spent moss litter by steaming it in a boiler, passing the
vapour through sulphuric acid, to obtain sulphate of ammonia, evaporating the
liquor from the boiler to obtain nitrate and other salts, and drying the residue for
fuel, substantially as described.
