Life Cycle Energy Analysis as a Method for Material Selection

This paper presents a method of performing Life Cycle Energy Analysis (LCEA) for the purpose of material selection. The method applies product analysis methods to the evaluation of material options for automotive components. Specifically, LCEA is used to compare material options for a bumper-reinforcing beam on a 1030 kg vehicle. In this analysis, glass fiber composites and high-strength steel beams result in the lowest life cycle energy consumption. This paper also presents a set of life cycle energy terms designed to clearly distinguish between energy consumption occurring during different phases of a product’s life cycle. In addition, this paper compares the results of the LCEA method to those of other energy analyses and demonstrates how different methods of varying thoroughness can result in different material selections. Finally, opportunities are identified for extending this type of analysis beyond both automotive components and energy consumption. In particular, this paper identifies the need to develop similar methods for other environmental indicators.

The method applies product analysis methods to the evaluation of material options for automotive components. Specifically, LCEA is used to compare material options for a bumper-reinforcing beam on a 1030 kg vehicle. From an energy perspective, glass fiber composites and high-strength steel beams performed best.

Life Cycle Energy Analysis

In this paper, energy consumption models of retreaded engineering tires were constructed based on life cycle analysis, theoretical calculation model, and energy consumption method during the four stages of retreaded engineering tires, i.e., production, transportation, usage, and recycling stage. The energy substitute model and energy evaluation index during the recycling stage, which involves one of five classical retreaded engineering tire recycling methods, i.e., secondary retreading, mechanical smash, low-temperature smash, combustion decomposition, and combustion power generation, were presented. Life cycle energy analysis of retreaded engineering tires was conducted, and the energy consumption during the different life cycle stages was quantitatively analyzed, thus obtaining the energy restoration rate of the five classical recycling stages of retreaded engineering tires. Energy consumption analysis and energy evaluation at different stages were performed. Main conclusions indicate that the energy consumption during the production stage is the highest, and energy consumption during the transportation stage is the lowest. The energy recycling result of the secondary retreading or combustion decomposition of retreaded engineering tires is obtained.
