“…Loss et al [6] compared the traditional open-cut and pipe bursting systems for relining water pipelines with lifecycle assessment (LCA) and found that the pipe bursting technology generates lower environmental impacts in most of the impact categories. Uche et al [7] provided a comprehensive approach with LCA in water management use in a Mediterranean water-stressed region.…”

LCA/LCC Model for Evaluation of Pump Units in Water Distribution Systems

et al. 2019

In this multidisciplinary research, an LCA/LCC model is developed for assessing the costs, energy consumption, and greenhouse gas (GHG) emissions during the pump unit lifecycles in drinking water distribution systems (WDS). The presented methodology includes the pump, motor, and variable frequency drive monitoring as a system (pump unit), through their life-cycle stages: the manufacturing stage, the exploitation stage, and the disposal stage at the end of their life-cycle. The developed model also analyses other processes such as the maintenance, testing, and reconstruction of the pump unit. Demonstration of the presented methodology was performed using the pump unit of an operating WDS system in different scenarios, in order to illustrate the proper application of this model. The obtained results show that the application of pump units is justified in terms of energy consumption. The results also show that 93%–94% of the consumed energy and the LCC costs are related to the pump operating costs, while the rest are related to auxiliary operations. The findings show that various countries can have considerably different prices of electrical energy and different GHG emissions that depend on the source of electric energy. The implemented model incorporates some of the symmetries that are commonly found in the mathematical models of water distribution systems. Finally, the results of pump unit exploitation within the WDS have been used to show the impact of such plants on different levels of energy consumption, GHG emissions, and LCC production.

“…Therefore, reliable quantitative environmental assessments of different scenarios for ACW are necessary to identify in a trustworthy manner the less environmentally impacting solution, considering its whole life cycle. Life cycle assessment (LCA) methodology represents a standardized environmental management tool to quantify the potential environmental impacts associated with a process or product during its whole life cycle. − However, the LCA studies applied to the different management possibilities for asbestos containing waste, are surprisingly infrequent, and this is due to the fact that no impact assessment method exists for asbestos emissions in soil, water, or air …”

“…23−25 However, the LCA studies applied to the different management possibilities for asbestos containing waste, are surprisingly infrequent, 26 and this is due to the fact that no impact assessment method exists for asbestos emissions in soil, water, or air. 27 Some strategies have been proposed to partially overcome this limitation. The work by Terazono et al, 26 although limitedly to the disposal stage of asbestos life cycle, for the first time attempted at quantifying the health risk of asbestos, by proposing a solution to the pulse-flux issue (i.e., the difficulty in calculating the health risk from an emission due to the lack of data related to emission duration), through an estimation of asbestos exposure dose and the calculation of the conversion factor expressing the relationship between exposure dose and health risk.…”

This work addresses the complex issue of asbestos containing materials (ACMs) management, by focusing on the scenario of six municipalities comprised in the Reggio Emilia province of Emilia Romagna Italian region. Particularly, the life cycle assessment (LCA) methodology was applied in order to assess in a quantitative and reliable manner the human toxicity as well as the ecotoxicity impacts associated with all of the different phases of ACMs management. The latter comprises mapping of ACMs, creation of a risk map for defining priority of intervention, encapsulation and removal of ACMs, as well as the as obtained asbestos containing waste (ACW) end of life. Particularly, a thermal inertisation treatment performed in a continuous industrial furnace was considered as the innovative end of life scenario to be compared with what actually was provided by the legislation of many countries worldwide, that is, the disposal of ACW in a controlled landfill for hazardous wastes. A characterization factor for asbestos fibers released both in outdoor air and in occupational setting was proposed for the first time and included in the USEtox 2.0 impact assessment method. This allowed us to reliably and quantitatively highlight that inertisation treatments should be the preferred solutions to be adopted by local and national authorities, especially if the obtained inert material finds application as secondary raw materials, thus contributing to a decrease in the environmental damage (limited to its toxicological contributions) to be associated with asbestos management.

“…According to this document, which is also used in this study in life cycle inventory (LCI), raw materials, their transport and pipe production processes have highest shares in ADP (elements), AP, EP, GWP values varying between ~ %54.03-75, which is followed by installation (~ %24-54) and transportation (~ %0.78-1.3) phases. Loss et al (2018) compared open cut and pipe bursting systems, which are pipe-relining methodologies, in terms of environmental impacts using ReCiPe 2008 H/H Europe Midpoint method. Due the lower need of soil excavation, backfilling of the trench and related fuel consumption, pipe-bursting methodology was advantageous for all environmental impact categories.…”

Pipelines that supply water from water resource to the reservoirs constitute an important part of water supply system construction. In this study, environmental impacts of construction of pipeline component of a water supply system in Van, Turkey are investigated using Life Cycle Assessment (LCA) methodology. Construction of pipelines is executed using conventional open cut system. Life cycle inventory (LCI) of the study is generated using primary data gathered and GaBi Professional database is used for background processes. CML 2001 was the environmental impact assessment method used. According to the results, the main contributors to AP, FAETP, GWP, HTP, MAETP are raw materials used for the production of pipelines which are high density polyethylene granules and carbon black. Most of TETP is generated because of installation of pipelines and sand used for backfilling the pipe trenches is responsible of this. Production and installation of pipelines end up with ADP due to the used materials. Transportation activities executed during the construction of pipelines have environmental impacts in every category considered; however, their contribution is not significant compared to the other activities conducted.
