The following table shows packaging weights and pallet configuration (for
practical example see Table 3.9 in Section 3.7)

Packaging (1-l beverage carton) Weight (g)

Weight primary packaging (carton) 31.5
Secondary packaging (corrugated cardboard trays) 128
Transportation packaging 24 000
Euro-pallets (wood)
Pallet foil 280
Pallet pattern
Carton per tray 12 pieces
Trays per layer 12 pieces
Layers per pallet 5 pieces
Cartons per pallet 720 pieces

1. Calculate the degree of utilisation of the truck (for filling good simplified:
1l = 1kg)
2. Calculate the fuel consumption (in litre Diesel) for a distance of 100 km for
a truck loaded with 24 pallets. Assume a linear dependence between the
fuel consumption and the utilisation rate. Finally, derive the specific energy
consumption from the fuel consumption.
3. Calculate the fuel consumption (in litre Diesel) for a distance of 100 km for a
truck loaded with 24 pallets related to the fU.
