Abstract

A newly manufactured 5-speed manual transmission is compared with a genuine remanufactured transmission of identical design. The Life Cycle Assessment covers the entire product life cycle from production through to disposal. In all the environmental impact categories considered, the remanufactured transmission performs significantly better than the newly manufactured unit. The environmental improvements are attributable to the substantial reduction in material and energy consumption. Transport of used transmissions to the remanufacturing facility accounts for only a small fraction of total life cycle environmental impacts. Energy consumption is reduced by 33 % for the remanufactured transmission compared with a newly manufactured transmission.
