• Assume everyone takes one paper towel to dry their hands.
• Energy consumption of recycling plant: 0.16 tonnes of fuel oil
(combustion) + 600 kWh of electricity per tonne of recycled
paper towels.
• Emission Factor for fuel oil in combustion: 3.19 kg CO2Eq/kg
• Assume electricity energy is generated by coal with an emission
factor of 0.32 kg CO2Eq/kWh.
Transport distance from the paper towel production plant to
point-of-use: 400km
• Emission Factor for diesel consumption in transportation: 3.32
kg CO2Eq/kg
• Density of diesel = 840 kg / 1 m3
• Diesel consumption of truck: 45 liters per 100 km
• Capacity: 10 tonnes of paper on the outward journey, empty on
the return journey.
• Assume the truck consumes the same amount of diesel
regardless of the weight carried.
• Weight of one dry paper towel: 15 g.

Quantitative Analysis Question III (Please show calculation steps,
solutions obtained without calculation steps will receive a zero point)
SuperSmart Inc. is considering using disposable paper towels for
hand drying in their new office building. These paper towels are
made from 100% of post-consumer recycled paper fiber. The paper
towels are transported from a recycling and manufacturing plant
that produces them.
Please help the company conduct a life cycle analysis to assess the
carbon footprint of using these paper towels to dry one pair of
hands. Show your calculation steps.
