Optimization Of Wood Bioenergy Plant Raw Materials Supply Chain Based On LCA

With the global and rapid development of economic, the demand of people for energy is also increasing, which prompting today’s mainstream energy-fossil fuels also faces enormous demand pressures, as well as the face of severe shortages of fossil energy consumption, leading to a global "energy crisis ", " greenhouse effect "gradually prominent, gradually strong voice of the new clean and green energy, in this context, the countries have reached a consensus that we must be sure to develop and implement renewable energy systems by improving the energy consumption structure, the development of environment-friendly as well as unlimited potential new type of energy to reduce dependence on fossil fuels, thereby reducing global energy consumption and greenhouse gas emissions. New biomass energy is one of them has great potential, which can effectively replace fossil energy resources, while reducing greenhouse gas emissions. Biomass energy production is largely dependent on the stability of the stability and efficiency on the supply of raw materials, so in this paper, its raw material supply chain is studied. The optimization design of supply chain network can effectively improve energy productivity, ensure a steady energy efficient and low-cost supply to meet the energy needs of people, thus contributing to social stability, health, harmonious development.From supply chain perspective, life-cycle (Life Cycle Assessment, LCA) method is used, which fully consider the characteristics of temporal and spatial distribution of biomass, biomass production, biomass transport prices and other uncertainties, established three cost models: economic costs of raw materials supply chain carbon emissions cost model and the total cost of the raw material supply chain model, and optimize the carbon tax as a constraint condition. Finally, in order to analyze an example of a business, and three kinds of cost model were analyzed, and optimization by comparison, it can be well expected results, and to verify the reliability of the scientific model. And put forward the main link of the supply chain management a number of recommendations to achieve the supply chain, economic and environmental benefits and win-win situation. Specifically, this paper has done the following work areas:(1)Review classification of wood biomass feedstock supply chain-related literature. By contrast research status of domestic and foreign literature, draw a hot topic at the contribution and problems; (2)Low-carbon research LCA models. This paper considers the woody plant biomass feedstock supply chain links carbon emissions during raw material procurement, transportation, pre-processing, production, combined with the LCA method, economic considerations and the establishment of a bi-objective nonlinear model of environmental costs; (3)Application of the model. Using the established model of a biomass energy plant raw material supply chain optimization, and gives the rationalization and optimization recommendations based on woody biomass plant raw materials supply chain optimization model LCA of this paper is on the traditional supply chain optimization model a strong complement to the study, verified examples amply demonstrate the effectiveness and practicability of establishing a model for other supply chain optimization also has great reference value.
