This paper deals with specific the geothermal heating project with low-temperature reservoirs in specific districts of China and attempts to make a comprehensive life-cycle assessment of it. We apply the environment impact potential method to evaluate underground construction, aboveground construction, operation and decommissioning stages of the project. Compared with other energies the result of 17.08 person equivalents indicates that geothermal is a clean energy. The coal-fired electricity used in operation stage is the largest source of environment impact.

Research and Practice Environmental Life Cycle Assessment (LCA) can be used to evaluate the environmental impacts of a building resulting from manufacturing, construction, operation and maintenance and the end of life demolition and disposal/re-use. Tracking impacts such as greenhouse gas emissions and smog formation, LCA can enable comparison of building proposals testing options of material use, system selection and system performance.

The Impact

To study the impact of the promotion of electric vehicles on carbon emissions in China, the full life carbon emissions of electric vehicles are studied on the basis of considering such factors as vehicle weight and grid mix composition, and fuel vehicles are added for comparison. In this paper, we collect data for 34 domestic electric vehicles, and linear regression analysis is used to model the relationship between vehicle weight and energy consumption. Then, a Hybrid Life Cycle Assessment method is used to establish the life cycle carbon emission calculation model for electric vehicles and fuel vehicles. Finally, the life cycle carbon emissions of electric vehicles and fuel vehicles under different electrical energy structures are discussed using scenario analysis. The results show that under the current grid mix composition in China, the carbon emissions of electric vehicles of the same vehicle weight class are 24% to 31% higher than that of fuel vehicles. As the proportion of clean energy in the grid mix composition increases, the advantages of electric vehicles to reduce carbon emissions will gradually emerge.

There is a huge impact of railway projects on the regional environment. A life cycle assessment (LCA) framework using quantitative methodwas developed to evaluate the environment impact of railway projects quantitatively. The railway life cycle was divided into 5 phases: survey and design, raw materials processing, construction, operation, and demolition. The life cycle environmental impact for railway project was categorized into 5 grades: great negative influence, little negative influence, no influence, little positive influence, and great positive influence. Based on the improved AHP method, a quantitative method was introduced to evaluate comprehensive environmental impact of railway projects. A railway project was analyzed as a case study. The results show that the major environment impact is occurred during the phases of operation and demolition. It is demonstrated that the method is applicable to assess the life-cycle environmental impact of railway projects.

Lca Results

Life cycle assessment (LCA) of a building is a new methodology which accepted as one of the best ways to estimate the environment impacts of a building during its life. In this paper, LCA analysis on a primary school wooden dormitory was conducted using Athena software firstly. Then two others construction materials, namely, concrete and brick, were assumed to be adopted to construct the dormitory. Also the LCA analysis was conducted on the two dormitories using concrete and brick. The comparison on LCA results of the three buildings using different construction materials showed that the dormitory constructed by wood is relatively greener than that of dormitory constructed by concrete and brick.

Babat Drinking Water Treatment Plant (IPAM Babat) is one of the clean water facilities for Lamongan community. The process of clean water requires an appropriate processing. This process requires chemicals and energy that it will adverse effects to the environment. Life Cycle Assessment (LCA) is one of the environmental effects analyze methods for clean water process. The four phases of LCA are Goal And Scope Definition, Life Cycle Inventory, Life Cycle Impact Assessment, and Interpretation. The environmental impacts of the LCA method of processing are divided into three broad categories of impacts, namely the categories of human health, ecosystem quality, and resources. The result of LCA analyzed shows that electrical energy utilization product an environment impact significantly. This impact has consequences on the resource category (fossil fuels) and human health (climate change) due to CO2 combustion. The largest electric consumption is used for tools of pumping water due to the distant length intake and IPAM. The solution for reduced the electric consumption is using the equipment efficiency and water flow system by the power of gravity.

Cathode Copper

The environmental impact of Chinese cathode copper production was identified and quantified in the context of pyrometallurgy ical and hydrometallurgical method by life cycle approach. Combined with the situation of copper resources in China, the copper ores mining, mineral processing, transportation and smelting sector, were analyzed in detail. The normalization results shows that abiotic depletion is the largest environmental impact in both Pyro-and hydro-metallurgical methods, which were 28.4 kg Sb eq and 32.0 kg Sb eq, respectively. Electrolytic refining is the key process in hydrometallurgical life cycle environmental burden (50.21%), and the mining process contributed the largest environmental impact (17.94%) in pyrometallurgical process. In addition, the total environmental burden of pyrometallurgical process is 1.15 times of hydrometallurgical process. Pyrometallurgical methods has many environmental impact category which were much higher than hydrometallurgical because of the more use of fossil fuels in smelting process. Based on the life cycle assessment results, the key factors to reduce the overall environmental impact for China’s cathode copper production include optimizing the efficiency of copper resource, and clean energy sources for electricity production.

This paper presents quantitative environment impact evaluation and assessment of inkjet printed flexible cable on soft substrates for Electrocardiography (ECG) monitoring. The studied printed ECG cable is fabricated by inkjet printing of nanoparticles wire on paper substrate which enables wireless transmission of ECG signals between bio-electric electrodes and central medical device. In order to facilitate the inventory analysis, the environmental impacts evaluation of inkjet printing technology has been carried out by comparing with traditional ECG cables. With the life cycle inventory modelling by using GaBi software, the life cycle assessment (LCA) was conducted to qualify the input and output of raw material resources, energy resources used in manufacturing phases and the impacts to environment.

This study aims to measure the environmental costs (eco-cost) and the eco-efficiency ratio rate (EER) of the production of pencils and formulate some recommendations to improve the manufacture sustainability. The measurement of Eco-efficiency was performed using life cycle assessment (LCA) with the eco-cost method. The pencil manufacturer produces a waste of 20 %, and the product rejects 37 %. The material used is wood, slat, and chemical material for painting. The result of the data processing shows that the eco-costs of IDR 50.593.583 for 4200 grosses production lot size. The eco-efficiency index or EEI for pencil product was 1,69, which means that the products are affordable and sustainable. The eco-efficiency ratio rate (EER) is 41% means that pencil production processes need improvement. The single score Impact Category Diagram shows that the most significant environment impact category is climate change. The recommendation to improve the EER of pencil production based on Impact Category Diagram is (1) to increase the utilizing of wood waste and (2) to increase the capability of technicians and operators to reduce the product rejection. These recommendations aim to reduce the wood consumed in production.
