Carbon Footprint Analysis of Pallet RemanufacturingIn Journal of Cleaner Production, March 16, 2016 (Online Reference: DOI: 10.1016/j.jclepro.2016.03.009)Debjit Roy, Fabiana Tornese, Andres L. Carrano, Brian K. Thorn and Jennifer A. Pazour This research is the first attempt to
characterize the carbon equivalent emissions associated with pallet
remanufacturing operations for two repositioning scenarios (cross-docking and
take-back), and under multiple levels of pallet loading and service conditions.
Industry data was acquired through observation and time studies at 12
facilities in North America. Models of pallet component breakdown patterns were
used to characterize the carbon equivalent emissions of pallet remanufacturing
over the predicted service life. Results show that materials account for the
vast majority of remanufacturing operation emissions with three board
components responsible for 50-90% of total remanufacturing emissions. The
loading and handling environment significantly impacts remanufacturing
emissions thus breakeven points where remanufacturing emissions exceed those from
newly manufactured pallets are provided for each condition. Also, a
pallet-cross-docking policy was shown to reduce emissions when compared to a
take-back policy. Finally, a linear optimization model is provided to
understand the benefits of preemptive component repair. Results show that
preemptive remanufacturing schedules can reduce carbon equivalent emissions by
up to 40%. These insights can help guide the pallet industry towards more
sustainable pallet management strategies.
