Effective micro-organisms are used to make compost out of the Press-Mud (PM) of Sugarcane Factory. Some sugar industries use the Spent-Wash which have very vital nutrients but high values of COD and BOD in making compost for zero discharge of their distillery effluent. The end product (Bio Compost) produced with Maple EM.1®, Spent-Wash of distillery and Press-Mud is rich in nutrients.
Process of making Compost with sugar mill Press-Mud and Spent-Wash.
Windrows are made with the Press-Mud in size of 3 Mts. Wide and 1.5 Mts. In height and turned with the homogeneous compost turning machine. The initial moisture of Press-Mud is brought down to 48 to 50 %. This can be done by turning the windrow for five to seven days (this depends on the initial moisture of PM).
In the second phase the 6lts. Of AEM (activated EM) per tone of PM is added in the tank with spent-wash and it is sprayed over the windrows. Everyday the level of moisture is monitored and then add the spent-wash in such a way that level of moisture do not exceed more than 60 %. Everyday take the temperature of windrows in at different places. It will reach above 600 C. This will kill pathogen in the press-mud. This temperature is indication that the hemophilic bacteria are working and they are breaking the complex molecules to simple ones. These conditions will remains for few days and then the temperature will start to decline. As the temperature start to drop and on visual look, the PM is turned to blackish humus; stop the spraying of spent-wash and leave the windrow for curing.
Bagasse based boiler fly ash can be added in the compost @ 10% as it give organic carbon, silica, N,P,K, Ca, Mg, & S, trace elements. Bagasse based boiler fly ash is the only product, which provides silica of origin to considerable extent. Silica is known to play important role in wall integrity & strength. It is especially important in crops like paddy, wheat & sugarcane.

MAKING ACTIVATED EM FROM MAPLE EM.1 (STOCK SOLUTION)
For making AEM mix Maple EM.1, Molasses and chlorine free water in proposition of 1:4:45 and fill the tank up to the top and mix them properly. Leave no space for air. Fix one small ¼” dia tube on the top lead for discharge of gas produce during fomentation. Deep the other end of tube in water can so the air will discharge from the tank but on fresh air will enter in the tank. In winter AEM will be ready in 7 to 8 days and in summer day it will be prepared in 3 to 4 days. Don’t prepare it in open and under direct sun light. Start to use AEM when the pH of solution is in between 3.5 to 4.
