2.4.1. Goal and scope definition
The goal is to compare different MSW management alternatives
from the life cycle perspective. The functional unit of the study is 1
ton of generated MSW in Sakarya. Consequential LCA is used for
defining system boundary because consequential assessment describes
how relevant environmental flows will change in response
to possible decisions. As can be seen in Fig. 2, the system boundary
of the study that defines what is and is not included in the
assessment starts with the collection of MSW and includes waste
transport, MSW material recovery facility (MRF), waste treatment
alternatives (recycling, incineration and composting) and landfilling
of waste. In this study, the following waste treatment alternatives
are modeled so that we can compare their environmental
impacts
