ABSTRACT
Carbon reduction is the conservation movement in the attention of a concept and practice. To be able to really achieve the effect of carbon reduction, one of the more effective method is to analyze the carbon footprint of various activities from logistics system. To understand a variety of activities release the amount of gas emissions, taking further effective measures to achieve the purpose of saving energy and reducing carbon emissions.
Second-hand clothes system is a ring that can not be ignored in the entire logistics system. This system contains at least three kinds of recycling method: recycling and using again, recycling and processing and incineration. In this study, First thing is to analyze three categories of second-hand clothes recycling system. Understand which activities associated with the process. Then proposed the calculating formula of three greenhouse gases, namely carbon dioxide, CO2, methane CH4, and nitrous oxide N2O, further establish a gas emissions model of the three categories of second-hand clothes recycling system. Finally estimate the amount of greenhouse gas emissions and be a basis of carbon footprint analysis.
This case studying is based on a manufacture of recycling in Japan. Through out the operations of this company collect data needed. And separate recycling system to 3 different way: 1. Package the second-hand clothes and sell them to Third world. 2. Clothes make into wiper. 3. Incineration. Using the established model to analyze and investigate greenhouse gas emissions. Conclusion refers to incineration is the most carbon emission in the three procedures of second-hand clothes industry. And this case-study also present effects of economic. It is worth a visit for environmental group to make decision as a reference of conservation units.
Keywords: Recycling systems, second-hand clothes, reverse logistic
