At the full-scale facility two different types of studies were conducted.
During the first study, three trenches were sampled at five different points;
these locations were chosen to represent five different time points in the MSW composting process.
The second, separate study consisted of following two MSW loadings throughout the composting process.
The first trench functioned as a control to the second trench, where 22.68 kg of nitrogen, in the form
of ammonium nitrate, was added (at the front end) to 12.7 tons of MSW.
