The Analysis Carbon Footprint of TDG Bamboo Laminated Column

From the global warming problem at present caused by many sources, building materials are another cause that directly and indirectly affects the environment. A carbon footprint is another way to measure the environmental impact of the product. In this paper, TDG bamboo in Thailand used for processing into the standardsized bamboo columns and analyzing the carbon footprint resulting from the production process. The strips of TDG bamboos glued together to the size 50×50×1000 mm. The results have shown that transportation produces the highest carbon footprint approximate 0.0716 CO2 ton compared to other processes.

A. Carbon footprint in Thailand
Carbon footprint analysis of the product by calculating the number of greenhouse gases emitted from the production process In each type to calculate it in terms of carbon dioxide equivalent (tCO2e). The carbon footprint of Thailand compared with other countries around the world, not to higher, but when studying the statistics of the increased carbon dioxide in the graph shows a rapid increase. [1]

Fig 1 Carbon dioxide emissions in Thailand
In Thailand, 2017, carbon dioxide emissions per capita average of 3.90 tons of carbon dioxide per person, down slightly from 2018, with average emissions level of 3.92 tons of carbon dioxide per person. Considering the last ten years found that per capita carbon dioxide emissions are likely to increase. [2] Carbon dioxide in the atmosphere caused by natural and human-made factors, such as deforestation, Residence, or agriculture. The most critical space probe that emits carbon dioxide into the atmosphere due to trees. The forest absorbed carbon dioxide into the atmosphere. Decline in forest area, As a result, the amount of carbon dioxide in the atmosphere increases. [3] Results of the study of the amount of oxygen, carbon dioxide by the IPCC (Climate Change Intergovernmental Agency) in the year 1980 shown that the amount of carbon dioxide generated from deforestation for use as urban or agricultural areas is estimated. 1.6 Gtc. Thailand, the decline of forests equal to 0.39 percent or 1,261,761 rai. Ninety-eight hectares per year, an increase of population in the country on average 680,000 people a year that would show that. If the population increases by one person, forests decreased by 1.86 rai (average period of 56 years from 2504 to 2560. [4]

B. Dendrocalamus Gigantues bamboo(TDG)
Thailand is the country where most of the population is agriculture.Following the economic development plan of Thailand year, 2060-2021(BC.) which, focuses on restructuring the production of Thailand, changed from the agricultural sector to the industry sector. [5] Economic developmentbamboo production and manufacturing provides job opportunities in less developed countries that need social and economic sustainability. China, the world's largest bamboo producer, was valued at over 19.5 billion USD in 2012, employing over 7.5 million people. This serves as a model for other countries looking to develop a sustainable bamboo industry. [6] Bamboo is sustainable materials because of once time; if we grow the bamboo, they keep growing without replanting until 60-130 years, depending on the species of bamboo. [7] Renewable resourcebamboo can be harvested in one to five years, depending on the species. In comparison, hardwoods like

As a substitute for hardwoods, bamboo offers a versatile solution. To use the bamboo for building nothing new for people in Thailand but to developing into the industrial process very low. [8] [9][10]Bamboo absorbs greenhouse gases bamboo sequesters carbon dioxide from the environment and produces 35% more oxygen than its equivalent size of trees. Large-scale bamboo plantations can become effective "carbon sinks" or areas designed to reduce CO2 from the atmosphere. When bamboo fibers are used to construct buildings, the carbon is sequestered (stored away) for the lifetime of that building.
In Thailand, bamboo growth everywhere in Thailand, but most growth in the north. The resource capacity of TDG bamboo Nan province the yield of bamboo 6-10 inches long 25-35 meters 120-150 culms/rai per year. The bamboo harvest from Nan's Bamboo Garden, which total of culms approximately 840,000-1,050,000 culm/years. The bamboo grows in the three types of forest. [11] The data from the Ministry of Natural and Environment Thailand. The mechanical properties of bamboo are based on ASTM D143-09 [15] and Standard for the wood test in Thailand (DPT 1221-51). [16] The details of the specimen's size 63×50×50mm with the test results range of the stress between 52-117 kg/cm 2 . The bending strength of TDG laminated [11] Average of the modulus of elasticity; TDG beam coated with resin 270140.87kg cm 2 ⁄ , TDG beam without coated with resin 159457.74kg cm 2 ⁄ .From the test, results can be classified as a hardwood . From past research studies, it found that TDG bamboo has qualities that can be used to replace wood in the future. For TDG bamboo to be able to be environmentally friendly construction materials, this research has studied the carbon footprint of bamboo column production processes.

II. RESEARCH OBJECTIVES
The scope of a study; TDG bamboo used for experimental taken from Nan province, Tha Wang Pha at age 3 years. The TDG culms measured above 6 meters from the bottom culms and cut into 2 meters long set the code to 3 parts; bottom middle and top. In this paper, analysis of the carbon footprint from the production process of the standard bamboo column as shown in  The carbon footprint analysis of the circle of the process production 1 as the following

A. transportation
Transportation process for calculating the load and distance .in this research used two truck to load the TDG bamboo 100 culms which the detail of load as shown in

B .Preservation and Dry
The analysis in this process depending on the electric that used for drying the bamboo and the water that used for preservation The total carbon produced in this process approximately 0.002435 ton as shown in table 3 The carbon footprint analysis of the circle of the process production 2 .This process of strip making depending on the size of the bamboo and the electric tool used during the process .In this research, the factor of parts such as the bottom, middle, and top. The results as following A. Basic information The strip makes depending on the physical property;TDG bamboo at the bottom have the most significant size in both circumference or thickness as shown in  The physical property directly affects the carbon footprint during the process because the thickness of the bamboo is hard to cut the process used more time and tool to finish.as the following carbon footprint calculation

B. strip making with the bottom part
The strip making at the bottom part produced the carbon footprint approximately 0.0004 ton Table 5 calculation the carbon footprint during the strips making

C. strip making with the middle part
The strip making at the middle part produced the carbon footprint approximately 0.0004 ton Table 5 calculation the carbon footprint during the strips making

D. strip making with the top part
The strip making at the top part produced the carbon footprint approximately 0.0003 ton Table 5   The carbon footprint analysis of the circle of the process production 3.The bamboo column is a forming process; this process that affects carbon footprint while using the glue and electrical tool for cutting and sanding the columns. Following the results of the test A. Glue weight For the carbon footprint of forming the column, the critical factor as glue weight .The results show that the top part used more glue than another part. It applied more strip that other parts because of more glue to the adhesive. This process, the strip glued together with clamp compresses the column for more than 8 hours .In this process, only glue causes carbon during the process. The results as shown in table  6   Table 6 calculation the carbon footprint during the forming process The comparison of the forming process different part as shown in fig 8 shown that the glue that used for top part more than Other parts cause produced more carbon credit.  The carbon footprint that produced during made the TDG bamboo column laminated approximate 0.074 tons per size 2×2 inch long 1 meter, which can reduce the carbon credit by used the local bamboo.
