Abstract
Life Cycle Assessment’s (LCA) point of view, means more elementary
processes after the product’s use phase. However, this choice affects the
early steps of its life cycle, usually by decreasing demand on acquisition of
raw-materials, lower need of manufacturing processes, and an adition of life
time. This paper aimed to discuss the influences of the Remanufacturing
Scenario on early steps of its life cycle. The methodology used was the LCA
based on LCA standards. We used as study case an air compressor and
compared the Remanufacturing Scenario with a Reference Scenario where
the final disposal was set the equipment to a landfill. The Life Cycle Impact
Assessment was performed with the software SimaPro®7.3 and CML2000
method for Abiotic Depletion and Global Warming, and Total Acumulative
Energy Demand (single issue). The case study showed that the
Remanufacturing as EOL Scenario is able to decrease until 47% of the
impacts compared to the Reference Scenario. However, this improvement
can not always represents a better environmental performance when
considered a numerical balance of the impacts inside each phase.
