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.

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.

This paper presents aspects concerning the life cycle assessment of the electroconductive textile functionalized by advanced RF plasma technology based on argon and oxygen gases and deposition of the metallic micro/nanoparticles. In order to obtain the textiles with electroconductive properties, the preliminary plan consisted functionalization of the textiles by using RF plasma technology based on argon and oxygen gases and processes for micro/nanoparticles deposition such as foulard, direct printing, and thin film position. It was analyzed the life-cycle inventory (LCI) and was provided the study for life-cycle assessment (LCA) using SimaPro software and Eco-indicator 99. In order to obtain the LCI, we used to input and output technical data, from the plasma process, and the SimaPro software for generating the LCI and LCA. The input data about raw material, energy, chemical substances, have been collected by direct measurements on machinery, device log, and specifications of the equipment (technical books) and processes. The output data was obtained using SimaPro software connected to internet-specific databases. The purpose of our research has been to study the life cycle assessment of the electroconductive textiles functionalized by RF plasma technology in comparison with classical functionalization treatments.

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.

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.

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.

In article the question of a problem of processing of household waste which in our life became today especially sharp is brought up. Still absolutely new things become not necessary as quickly get out of fashion. Before consumers there is a task how to prolong life cycle of textile materials of high quality. The approach allowing to develop conditions of production of garments with a possibility of use differently of textured materials in one model design is represented.
