management system. The data collection phase
involves a thorough assessment of the company,
from the purchase of various inputs to the output.
Data such as the types of batteries, demands and
prices of each product, raw material prices and ma-
terial requirement plans are obtained in this phase
of the study. The demand forecasting procedure
and bill of material of a car battery are obtained.
The current production planning and scheduling
system are analyzed. Each manufacturing process
is analyzed in detail to determine the operations
forming wastes. The manufacturing process of
a car battery and wastes derived from each unit
process are shown in Figure 1. The waste manage-
ment system of the company involves the entire
procedure of collecting, transporting, processing,
recycling and disposal of waste materials. Infor-
mation about the production wastes (quantity and
rate of generation) is collected. The composition
of wastes and waste management costs are investi-
gated. Current waste management practices in the
company are determined and analyzed with respect
to their appropriateness in terms of environmental
and economical benefits. Making detailed analysis
