Study On Carbonprint During Tire Life Cycle

With global warming, greenhouse effect is getting worse, the main culprit ofgreenhouse carbon dioxide have also gotten more and more attention. Carbon footpirntis otfen referred to as "carbon consumption" refers to an institution or individual formeasuring daily energy consumption due to carbon dioxide emissions arising from theenvironmental impact indicators. With this new indicator which is regarded as animportant weapon against climate change, businesses and individuals understand"carbon emissions" by identifying their "carbon footprint" to，then to control andrestrain the behavior of individuals and businesses to reduce carbon emissions in orderto achieve the purpose. In other countries，to control carbon emissions has become abusiness used to measure the importance of social responsibility standards, and in ourcountry, the demand for energy saving in the next, from the two sessions held since2010，low-carbon economy has become a guarantee for sustainable economicdevelopment the hot topic.According to National Bureau of Statistics,2005，China’s civilian car ownershiphas grown from16.1million in2000increased to31.6million, and by2010thisnumber increased to more than70million. Such a large car market, has also led to theproduction of tires. In2011，the national production of radial tire reached360million,while the Ministry of Industry and Information Technology，according to informationreleased in2009，China produced233million tires up. Each tire in the production,transport, use and ifnal disposal of the process will generate a lot of carbon emissions,such a huge consumer market also makes the tire’s contirbution to global carbonemissions should not be underestimated.Life cycle assessment method is the life cycle of a product system input, outputand its potential environmental impact of compilation and evaluation. The IPCCmethod is internationally recognized for the assessment of national greenhouse gas emissions standards. In this paper，using life cycle assessment method combined withthe IPCC method in which defines the different method of calculation of greenhousegas in different industries and also defines the definition of default, to study andanalyze the carbon emissions duirng the entire life cycle of the tire, from access of rawmaterials and energy, tire production, tire use and ifnal waste tire processing. Thengive energy saving advice to the tire industry.(1)The method uses a life cycle assessment (LCA) of the tire’s life-cycle energyconsumption and carbon emissions of the research and analysis;(2)Based on the established model of tire life-cycle carbon emissions combinedwith the collected data, to establish the inventory analysis for energyconsumption and carbon emissions during tire life cycle. The results showedthat: For one ton of tires in its life cycle, the total emission of carbon dioxideto the atmosphere is44.02t; and in the process throughout the life of the tire，the tire using process is the highest carbon emissions,94%. Compare tomechanical crushing method will re-use of scrap tires，The use ofincineration of waste tires generates550Kg more carbon dioxide emissionsper ton of tires;(3)Based on the study of carbon emissions and energy consumption of the re-useof retreaded tires, the results show the life of retreaded tires is around70%to90%of the life of new tire, and resource consumption is only1/3for thenew tires, and the per ton retreaded tires generate1.234tons of carbonemissions less than new tires. Energy-saving tires per ton generate2.53tonsof carbon emissions less than less than the average from the tire. Based onthese results, given the initial proposal to reduce carbon emissions.
