Analysis Of Processing And Utilization Of Harvested Moso Bamboo And Carbon Sequestration Capacity Of Bamboo Products: Evidence From An’ji County Of Zhejiang Province

Based on the statistical data of development of bamboo industry in Anji county of ZhejiangProvince where owned the most developed bamboo industry and Moso bamboo which has thehighest development and utilization level and economic value, this study had analyzed the overalldevelopment of bamboo industry and bamboo products structure in Anji county;The second isbased on the experimental and survey data, Making a comprehensive evaluation on the carbontransfer ratio in the process which bamboo stem being mad into products and the carbon retainedfraction of final bamboo products by using the life cycle flow analysis method; Finally,theuncertainty associated with the carbon retained fraction of final bamboo products estimated in thisstudy was evaluated with the Monte Carlo analysis, more specifically with the crystal ballsoftware.The results show that:(1) Anji county has developed bamboo industry and higher bamboo industrialized utilizationrate. Based on the analysis of the overall development bamboo industry situation in Anji County,the development of bamboo industry in Anji county is facing series difficulties,such as resourcesshortage, the labor tension, low industrial concentration and market competitiveness to beimproved. In spite of this, bamboo industry in Anji county has been developed at the national levelrange, and the industrialized utilization rate of bamboo is relatively high.(2) The result showed that the carbon transfer ratio in the process which bamboo stem beingmad into products by using different process technique was greatly different.Under traditionalprocess technique, the carbon transfer ratio from bamboo stem being mad into final products is65.79%; under recombinant process technique, the carbon transfer ratio from bamboo stem beingmad into final products is69.59%;therefore, the carbon transfer ratio under recombinant processtechnique is higher. Using recombinant technology,it can help improve the efficiency ofprocessing and utilization of bamboo and carbon transfer rate.(3) Different bamboo products has different carbon retained efficiency. In the30years ofthe period,woven bamboo products’annual carbon retained efficiency was43.69%; boardbamboo products’annual carbon retained efficiency was58.46%;the remaining bamboo products’annual carbon retained efficiency was17.76%. Board bamboo products’annual carbon retained efficiency was higher14.77%than woven bamboo products and higher40.7%than the remainingbamboo products. The main reason for this phenomenon lies in the different average lifespan ofdifferent bamboo products.(4)The comprehensive carbon sequestration capacity by using different process techniquewas greatly different.In the30years of the period, the comprehensive carbon sequestrationefficiency of the bamboo products was27.22%under traditional process technique; While, thecomprehensive carbon sequestration efficiency of the bamboo products was34.97%underrecombinant process technique. The main reason for this phenomenon lies in the final carbontransfer ratio from bamboo stem being mad into final products and the final bamboo structures aredifferent under different conditions.(5) Uncertainty analysis revealed that the range of the bamboo products comprehensivecarbon sequestration efficiency is major. Using Monte Carlo analysis, under traditional processtechnique, the bamboo products comprehensive carbon sequestration efficiency is a value between17.00%and39.52%, the result was sensitivity to the carbon transfer ratio of Pre processing stageembryo board and filar products. Under recombinant process technique, the bamboo productscomprehensive carbon sequestration efficiency is a value between19.76%and53.44%, the resultswas sensitivity to the carbon transfer ratio of Pre processing stage embryo board and its averagelifespan.(6) The comprehensive carbon sequestration efficiency of bamboo stem being mad intoproducts is strong under industrialization. Bamboo carbon sequestration can play an importantrole in responding to climate change, so we should increase the industrialized utilization ofbamboo in the future.The paper makes a summary and discussion of this research,recommendations are proposedas follows for developing the comprehensive carbon sequestration capacity:(1) Strengthening thecultivation of bamboo resources.(2) Improving processing technology, and strive to improve theutilization efficiency of bamboo.(3) Encouraging and guiding consumers to use more bambooproducts.
