Initial inspection revealed many of the basic features of a recycling program to be inadequately deployed or used. Overflowing garbage containers prevented source separation and required garbage and recycling within the classrooms to be collected daily as a single stream of waste. Through informal interviews, three teachers indicated that they had given up on enforcing source separation in classrooms after observing the maintenance crew mixing all waste streams during collection. The maintenance crew reported that neither the teachers nor the students properly separate their waste. A visual inspection confirmed that the vast majority of recyclable materials were discarded together with garbage. This observation was reinforced by the data collected during the first waste audit and depicted in Fig. 3.
