2012

This study assesses the water footprint (WF) of sugarcane and cassava in northern Thailand. The WF is an indicator that expresses the amount of freshwater embodied in each ton of crop produce. It varies considerably for each region, which is characterized by different climate and agricultural production systems. On average the WF of sugarcane (202 m 3 /ton) is less than that of cassava (509 m 3 /ton). At the provincial level, the WF of sugarcane is most intensive in Lampang (252 m 3 /ton) and less intensive in Kamphaeng Phet (167 m 3 /ton). Uthai Thani is the province where the WF of cassava is the highest (547 m 3 /ton), while Kamphaeng Phet has the lowest WF. If Thailand were to move toworads a low carbon society by switching from fossil fuel to bioenergy the effect on the volume of water usage in agricultural production is likely to increase. Therefore, the main problem facing Thailand will be water scarcity if water resource is not managed properly, this study showed the importance of water management for sustainable – bioenergy production and the competition for water resource between “water for food” or “water for energy”

During translation elongation, the ribosome ratchets along its mRNA template, incorporating each new amino acid and translocating from one codon to the next. The elongation cycle requires dramatic structural rearrangements of the ribosome. We show here that deep sequencing of ribosome-protected mRNA fragments reveals not only the position of each ribosome but also, unexpectedly, its particular stage of the elongation cycle. Sequencing reveals two distinct populations of ribosome footprints, 28-30 nucleotides and 20-22 nucleotides long, representing translating ribosomes in distinct states, differentially stabilized by specific elongation inhibitors. We find that the balance of small and large footprints varies by codon and is correlated with translation speed. The ability to visualize conformational changes in the ribosome during elongation, at single-codon resolution, provides a new way to study the detailed kinetics of translation and a new probe with which to identify the factors that affect each step in the elongation cycle.DOI: http://dx.doi.org/10.7554/eLife.01257.001.

NRCT Data Center · 2009

The market price of oil has increased tremendously over the last decade. One of the major influences has been the higher demand for energy consumption in developing countries. Thailand imports a huge amount of oil each year, mainly for the industrial and transportation sectors. Statistics indicate that the selling price of diesel in Thailand increased from 0.24 Euros per liter in 2000 to 0.56 Euros/L in 2006. This problem directly and suddenly affected all sectors which rely on this fuel. In order to relieve this crisis, the government tried to promote the development of biodiesel, which has the same function as diesel fuel but is less expensive. However, there are many kinds of biodiesel fuels: such as biodiesel from used cooking oil, from plants, or from animal grease. Some of these have similar properties to petroleum-based diesel, but may require extensive improvement processes. Jatropha shows great potential as an oil-producing plant source in Thailand. Nevertheless, from the life cycle aspect, to generate biodiesel from Jatropha oil, materials and energy must be consumed and emissions and wastes will be released into the environment. Therefore, it is necessary to quantify and verify the energy efficiency and the environmental impacts of Jatropha biodiesel production from the life cycle point of view. Thus, the objectives of this paper are to develop the life cycle inventory database of Jatropha biodiesel and to analyze the environmental impacts by using the concept of life cycle thinking. It is clearly shown that the cultivation process of Jatropha contributes the highest environmental impacts, compared to other stages in the life cycle, due ineffective cultivation management. Suggested improvements to the Jatropha life cycle are introduced to maximize the benefits of using Jatropha biodiesel and minimize the environmental impacts, in order to help ensure future sustainable utilization.

The Proceedings of the Symposium on Environmental Engineering · 2005

Life Cycle Assessment (LCA) becomes a more critical tool for ECP (Environmentally Conscious Products) designing. At the same time, Life Cycle Costing (LCC) and Environmental Accounting (Eco-Accounting) are becoming a necessary tool to make decision of WTP (willingness to pay) for avoiding certain environmental impacts. This paper proposes a conversion scheme of the environmental load reduction expressed in physical units due to countermeasures into money units based on the CO_2 emission dealing right price, which is able to be evaluated by the CO_2 equivalent NETS values. Additionally, several criteria for the environmental costs performance are proposed with case studies.

International Journal of Emerging Electric Power Systems · 2005

To achieve a sustainable power generation industry it is necessary to study the environmental impacts and economic costs of all aspects of a power generation plants’ lifecycle - from mining to electricity distribution, and, ultimately, decommission (from cradle to grave). One key component in improving and maintaining quality of life for consumers is the application of the Green Productivity Index (GPI) in order to evaluate the related factors of Life Cycle Assessment (LCA) and Life Cycle Costing (LCC). The goal of this research is to appraise the efficacy of decision-making tools in accurately assessing the potential results of ‘green’ improvements to coal-fired and natural gas-fired power plants in both ecological and economic terms. The recently developed Numerical Eco-load Total Standardization (LCA-NETS) evaluates environmental impacts by identifying and quantifying input energy and output waste released to the environment throughout the life cycle of a power plant. Environmental impacts caused by global and regional environmental issues are numerically calculated in the units of NETS. Environmental assessment tools such as LCA, LCC and GPI can be used to improve the ‘environmental friendliness’ of electricity generation by demonstrating the future sustainability of ‘green’ power generation plants and their contribution to the quality of life of consumer.

The life cycle inventory (LCI) data of electric power generation plays a vital role on LCIs of industrial products. However, there are no formal life cycle assessment (LCA) studies in Indonesia so far due to limited of LCA expertise and lack of sufficient databases relevant to domestic conditions. Therefore, the aim of this study is, firstly, to introduce a life cycle assessment (LCA) method for Indonesian electric power generation systems, secondly, to establish LCI data for electricity grid mix of Indonesia compared with three selected countries, Japan, Thailand and China and, finally, to analyze and to investigate the environmental burdens for these four selected countries from a life cycle impact assessment (LCIA) point of view using the proposed LCA-NETS (Numerical Eco-load Total Standard) method. The resulting LCA evaluations are discussed for further ecological improvement.

The Proceedings of the Symposium on Environmental Engineering · 2003

Mae Moh Coal-Fired Power Plant in Thailand has held the second share of utility power generation in Thailand, approximately 22.7% of all utility-produced electricity (EGAT, 2000). However, there are plenty of environmental arguments of this only one power plant that using coal energy for generating electricity. Therefore, understanding the environmental impacts of the power plant system is necessary in order to find possible and suitable ways for waste reduction and system improvement. The aim of the study is first to apply Life Cycle Assessment (LCA) with Numerical Eco-Load Total Standardization (NETS), which used for evaluating the environmental burdens by identifying and quantifying energy and materials used and waste released to environment based on the balance of L & R (Loader and Receiver) tolerance. And the Life Cycle Inventory (LCI) of the power plant system has been developed. The second is to determine the performance cost by using Life Cycle Costing analysis (LCC) and to compare with other types of coal-fire generating systems. As the result, environmental load and economical cost for comparative power plants are discussed from life cycle thinking point of view to indicate for the better ecological and economical coal-fired power generation system for Thailand.

Natural gas power generating plants account for 52.5% of all of the electricity produced in Thailand. The attractiveness of small amount combustion gas emission has brought about an increase in the number of natural gas power plants. On the other hand, natural gas is not a renewable energy source. The life cycle efficiency is negative, indicating that more energy is consumed by the steam than is produced in the form of electricity. It is very important, therefore, to understand environmental influences due to electricity production from natural gas, which can be an instructive component of any plan to reduce total emissions and also resource consumption. This study has introduced LCA and LCC to three kinds of natural gas power plant systems. As a result from the LCA and LCC point of view, the environmental load and the economical cost are discussed for further ecological and economical improvement.
