Sažetak
Mineral raw material transport directly affects a product’s unit price
and exhaust gases amounts. Transportation length is proportional to raw
material price; its low price enables short transportation distances only.
Taking into account stone aggregates delivered to Zagreb, the consequence
of exploitation fields closure in the Zagreb area, particularly
within the Medvednica Nature Park, we tried to answer the question of
the impact of transport distances on the greenhouse gas emissions.
Certain models will present environmental impact of the stone aggregate
transportation and of nearby city quarries. The generally accepted
public opinion on the closure of nearby city quarries as the best
solution to environmental pollution will have to be reviewed.
Mining works are predestined by mineral resources sites and limited
by real possibilities and intentions of the community, therefore the experts,
i.e. miners, geologists and other geoscientists, should be actively
involved in spatial planning.
During the years of intensive construction, millions of tons have
been delivered from distances up to 100 km. The question arises whether
some more rational solutions could be generated by more appropriate
spatial planning?
