Abstract

Bamboo flooring is our specialty forest products, production technology and product quality in the international advanced level. Bamboo flooring production process there are water pollution, emissions of harmful gases and other environmental issues, has brought some harm to human health. The last 3-4 years, a technology with the traditional laminated bamboo flooring significantly different new products - bamboo scrimber floor extremely rapid development and become the new darling of the flooring industry. However, the production of this new type of bamboo flooring degree of impact on the environment compared with the traditional laminated bamboo flooring how are still unknown. Life Cycle Assessment (LCA) is considered to be material or product environment impact assessment of the most scientific method in the evaluation of green, are playing an increasingly important role in protecting the environment and natural resources. The papers carry laminated bamboo flooring, bamboo the heavy bamboo floors life cycle assessment (LCA) study, the application of the current international advanced software SimaPro LCA evaluation, combined with the actual situation in China bamboo flooring throughout the life cycle of material and energy input , the output of quantitative analysis, analysis of the comparison of the two bamboo flooring manufacturing, use and waste incineration process materials, energy consumption, pollutant release and quantitatively determine the impact on the environment, \recommendations for improvement. The main research conclusions are as follows: (1) Life Cycle Impact Assessment of laminated bamboo flooring bamboo manufacturing process caused environmental load, about 59.3%, followed by the finished floor production, accounting for 21.1%, the slab at the production stage, production of the lowest environmental impact, accounting for 18%. In the production of laminated bamboo flooring, bamboo environmental impact of the production phase slab and finished product 2-3 times in two stages, because the power consumption of the stage, heat, water up to water emissions. Reduce the power of the preparation stage of bamboo and energy consumption is essential for improving the laminated bamboo flooring environment friendliness. The bamboo production stage the greatest impact on human health, followed by the finished product stage, the minimum slab manufacturing stage. Ecosystem quality bamboo manufacturing stage, followed by slab manufacturing, finished product a minimum; minimum resource depletion, bamboo production stage, followed by the finished product manufacturing stage, the slab manufacturing stage. Integrated bamboo flooring throughout the life cycle, product manufacturing stages of the environmental load caused to the environment, the use phase is almost not adversely affected. The abandoned stage due to the heat of the burning floor to take advantage of reduced the corresponding coal resources consumption, from a global point of view, has a positive effect on the improvement of the environment. (2) Life Cycle Impact Assessment bamboo scrimber floor slab manufacturing phase caused by environmental impact, accounting for 56.9%, followed by the bamboo beam manufacturing stage, accounting for 26.6%, the lowest environmental impact of the finished product stage, accounting for 14.4%. 2 times, 4 times of the finished product at the manufacturing stage of the environmental load of the slab production stage about bamboo beam at the manufacturing stage. Reduce the electricity and heat loss of the slab preparation stage friendliness is essential for improving the environment of the the bamboo scrimber floor. Slab manufacturing stage the greatest impact on human health and ecosystem quality, followed by the bamboo beam manufacturing stage, the minimum for the finished product manufacturing stage, followed by resource depletion, slab manufacturing stage, finished manufacturing order, bamboo beam manufacturing stage least . In the bamboo scrimber floor throughout the life cycle, product manufacturing stage load on the environment, the use phase the environment almost no adverse effects. The abandoned stage due to the heat of the burning floor to take advantage of reduced the corresponding coal resources consumption, from a global point of view, has a positive effect on the improvement of the environment. (3) two floor life cycle impact Comparative Study of Evaluation integrated bamboo flooring bamboo preparation stage of the environmental load is the bamboo scrimber floor bamboo beam preparation stage 1.64 times, but the former in the environmental load of the slab manufacturing stage just after by 1/4. Insignificant environmental impact of the two floors of the finished product stage. Overall, the environmental load caused by the manufacturing the 1m2 bamboo scrimber floor is about 1.61 times of laminated bamboo flooring, bamboo reorganization wood floors high raw material utilization, significant economic benefits, but from the standpoint of the environment, the environment the negative impact is greater than the laminated bamboo flooring. This study enrich our bamboo flooring product life cycle inventory database to promote the the LCA bamboo wood product life cycle assessment (LCA) research and application, as well as China's bamboo / wood products and even forestry industry sustainable development are of great significance.
