In the past, the selection of an energy resource for electricity generation was dominated by finding the least expensive power generating plant. Although such an approach is essential, there is growing concern about other aspects of power generation such as social, environmental and technological benefits and consequences of the energy source selection. The aims of this paper are first to introduce a life cycle assessment (LCA) scheme with the aid of the NETS (Numerical Eco-load Total Standardization) method that we have newly proposed. This method provides a numerical measure for evaluating the quantitative load of any industrial activity on the environment, and has been used to analyze the energy flow and the environmental loads of various power generation systems. A second goal is to develop a computer program to examine the applicability of technology options based on cost performance and environmental load reduction. A final goal of this work is to select the power system using life cycle assessment (LCA) and life cycle costing (LCC). As a result, environmental load and economical cost for various power generation systems are discussed from the LCA point of view for further ecological improvement.

Rising demand for sustainable development motivated our eco-friendly polishing method. In this study, fixed-abrasive polishing using a compact robot was proposed based on a new approach that includes the idea of secondary tools. The effectiveness of using a compact robot was investigated by life cycle assessment for eco-friendly polishing processing. The actual polishing process was carried out with low pressure to determine the potential of the proposed polishing method. As a result, low-environmental-load processing was achieved by machine downsizing without affecting the processing results by designing an independent pressure mechanism along the equipment’s main axis. The nano-surface could also be obtained with this method for glass material.

Foam glass is a new insulation building materials and plays an important role in building energy efficiency for its many excellent performances, such as small thermal conductivity, low coefficient of thermal expansion and high mechanical strength. Generally, the manufacturing process of foam glass mainly can be classified into two typical processes, the waste glass recycling process and glass melting process. In this paper, the process-oriented life cycle assessment is used to quantitative analyze and evaluate the environmental load, such as energy consumption and pollutant emission of the two typical processes. The results show that the environmental load of the glass melting process takes place in two stages of the foaming and annealing, and the raw material extraction, while the waste glass recycling process mainly come from foaming and annealing. Regarding the energy consumption of foam glass, waste glass process is lower 22.4% than the glass melting process, while carbon emissions is lower 24.8%, and the comprehensive environmental impact is lower 40%. Therefore, the findings will guide and promote the new technology application for the energy saving and green technology applications in foam glass industry.

Co2 Emission Reduction

To estimate the benefits of reuse building, this study selected 8 street-house cases from ¡§Old House, New Life reuse movement and calculated the average CO2 emissions of rebuilding and refinishing in their life cycle. The results indicated that the average CO2 emission is 103.14 kg-CO2 /m2 before renovation, and 5.73 kg-CO2 /m2 after renovation. The efficiency of CO2 emission reduction can be raised up to 60% and 70%. If the street houses extend their life span from 60 years to 90 years, the life cycle CO2 emissions can be reduced from the original 1.89 kg-CO2 /m2¡Eyr to 1.39 kg-CO2 / m2¡Eyr. It's advantageous not only to make the best of old houses, but to decrease the environmental load.

The environmental impacts of the dregs disposal in cement kiln and conventional production were contrastively evaluated by life cycle assessment (LCA) in this study. The results showed that the environmental load ratio of both cement productions followed the order of energy depletion potential (EDP) > depletion potential (ADP) > global warming potential (GWP) > acidification potential (AP) > human toxicity (HT) > photochemical ozone creation potential (POCP). The comprehensive environmental load of disposal dregs was 14.465×10-12/a, which was 3.98% lower than that of the conventional cement production. Moreover, the reduced percentage of the environmental load followed the order of HT> AP> POCP> EDP> ADP> GWP, which indicated that the reduced percentage of human toxicity and acidification reached 10.62% and 10.06% respectively. Thus, considering the environmental benefits, it would be a better method to dispose dregs instead of limestone in cement kiln.

Particleboard is not entirely a wood replacement but a particular material with its properties, making it more effective at different times than heavy or solid wood. The world’s biggest concern is environmental problems with formaldehyde as a particulate board binder that can lead to human carcinogenic agents. A cradle-to-gate life cycle assessment (LCA) of particleboard production was performed using openLCA software. The impact assessment was carried out according to the software’s features. This preliminary investigation aims to analyze the chemical composition of particleboard and identify its environmental impact. The Fourier-transform infrared spectroscopy (FTIR) system was used to track the functional group of aliphatic hydrocarbons, inorganic phosphates, and main aliphatic alcohols found in particleboards made in Malaysia. Based on the FTIR results, aliphatic groups were found in numerous aggravates that the spectroscopic infrared was likely to experience. The most important vibrational modes were C–H, at approximately 3000 cm−1, and –CH deformations around 1460 cm−1 and 1380 cm−1. Eight effect groups demonstrated that 100% of the input and all analyses produced the same relative outcome. The life cycle of a product is determined by pollution of the air, water, and soil. Thus, particleboard has a minimal impact on the environment, except for global warming.

Load Factors

A LCA (life cycle assessment) scheme for any industrial activity system is introduced to estimate the quantitative load on the environment with the aid of the NETS (numerical environment total standard) method proposed by the authors as a numerical measure. Two kinds of environmental loads respecting fossil fuel depletion as input resources to the system and global warming due to CO2 emission as output are taken into account in the present eco-criterion, in which the total eco-load (EcL) value is calculated from the summation of respective environmental load factors on the whole process in a life cycle of the system. This NETS method is applied to eco-management co-generation systems, in which a computer-aided output navigator proceeds the LCA estimation with ICON and Q&A communication. An operation scheme most friendly to the environment with a minimum EcL value, i.e., an eco-operation scheme, is derived from the optimization theory.
