![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.
