Use of environmental value stream mapping and environmental loss analysis in lean manufacturing work at Volvo

Abstract

Green production systems requires efficient production and low use of resources such as energy, material etc. To achieve this, there is a need for further development of continuous improvement tools in the “lean and green” area. This work deals with environmental value stream mapping (Environmental-VSM), which has been applied in two case studies at Volvo Penta Vara and Volvo Construction Equipment Braås. In the performed studies Environmental-VSM, as described by the US-Environmental Protection Agency, has been extended by the introduction of a loss model to show environmental losses. The combination of methods provides the user with hands-on tools supporting strategic as well as operational management. Examples of practical improvement actions that were found include reduction of energy use trough minimising idling losses and floor space as well as reduced waste flow through lowered packaging material usage.
