Abstract

The environmental impact of the re-manufactured aluminium alloy (LM6) street lamp has been analysed. The results have been compared to the new housing lamp made of aluminium alloy (Al Si12Cu1{Fe}). The methodology used to calculate life cycle inventory and environmental impact is BEES V4.07 and Ecoinvent V3 was used as reference since it is the most updated database. The results show that the reworked aluminium lamp has an environmental impact of 2.38 pts and compared to that of alloy (Al Si12Cu1{Fe}) which has an impact of 2.56 pts. The first major factor is that the housing remanufacturing process does not consider the primary production processes of mining, extraction and casting. The new housing includes the primary production processes and casting thus impacting heavily on the environment. The second major factor that contributes to the lower impact of the remanufactured housing than the new housing is the low energy use since the housing is not remanufactured by re-casting which is basically a re-cycling process.
