The second experimental phase was performed from mid October, 2004 to mid December, 2004. As suggested, used tissue paper was included to increase the volume of raw materials, while leaves were also added during the shredding process, in order to increase the level of nitrogen. The second experiment showed a slight increase in temperature compared to the first experiment. As of the 5th week in the rotating drums, the Tricho activators and the Control group showed faster decomposition than EM. Raw material in Tricho and Control groups was still present but in significantly lower levels compared to EM groups. The rotating drums showed faster decomposition compared to pits and sacks, mainly due to the frequent aeration that comes from turning the rotating drums twice each day. Notable decrease in the volume of raw materials was observed after 5 weeks (50%) in the rotating drums, while weather conditions did not cause any problems during this second (as well as the upcoming third) experimental phase.
