| Abstract |
Today the extraction of virgin raw materials has become more difficult, expensive, and even polluting, especially in the specific case of metals. For solving these problems, product remanufacturing seems relevant. Indeed, it is considered as one of the most effective circularity strategies, contributing in particular to limit the use of raw materials and the associated nuisances. However, it is necessary to quantify its benefits, especially from an environmental perspective. The objective of this article is to compare the CO2 emissions of a remanufactured product to those of a traditionally manufactured product. The studied product is a roadside mowing machine, which manufacturing and remanufacturing are made in France. The comparison of the two processes was carried out with OpenLCA software and Ecoinvent databases to estimate the CO2 footprint in each case. Thus, the reduction of CO2 emissions induced by remanufacturing has been estimated. As a result, a reduction of approximately 80% was found, which corresponds to the reduction of raw materials, including steel and iron, and the corresponding processed. |
