“…In order to evaluate the potential environmental impacts of the ORC waste heat recovery system in each phase of the life cycle, the LCA methodology [44] was adopted, which evaluates and describes in detail the mass, energy, and exergy flow of the stream, as a result of the mass, energy, and exergy balance applied to the devices. These flows come from and are exposed to nature at each stage of the life cycle of the process, which highlights the construction, operation, maintenance, and decommissioning phases [20].…”

In this article, an organic Rankine cycle (ORC) was integrated into a 2-MW natural gas engine to evaluate the possibility of generating electricity by recovering the engine’s exhaust heat. The operational and design variables with the greatest influence on the energy, economic, and environmental performance of the system were analyzed. Likewise, the components with greater exergy destruction were identified through the variety of different operating parameters. From the parametric results, it was found that the evaporation pressure has the greatest influence on the destruction of exergy. The highest fraction of exergy was obtained for the Shell and tube heat exchanger (ITC1) with 38% of the total exergy destruction of the system. It was also determined that the high value of the heat transfer area increases its acquisition costs and the levelized cost of energy (LCOE) of the thermal system. Therefore, these systems must have a turbine technology with an efficiency not exceeding 90% because, from this value, the LCOE of the system surpasses the LCOE of a gas turbine. Lastly, a life cycle analysis (LCA) was developed on the system operating under the selected organic working fluids. It was found that the component with the greatest environmental impact was the turbine, which reached a maximum value of 3013.65 Pts when the material was aluminum. Acetone was used as the organic working fluid.

“…Life cycle assessment (LCA) is a ''cradle to grave'' approach for assessing the environmental impact of all processes and materials involved in a technology. 59 Because of intensive energy consumption, the environmental load (carbon footprint and pollutant gas emissions) of conventional desalination plants has a much higher share (88.6%-99%) in operation stage than assembly and final disposal processes (1%-11.4%). 60 Utilization of solar energy can significantly lighten lifetime emission footprint because it almost eliminates the operational emissions.…”

“…It was originally intended to compensate for the economic and environmental limitations of traditional rainwater management measures through plant retention and absorption of infiltration rainwater (Luo & Li, 2014). This type of development's basic idea is to use small-scale and low-cost green ecological technologies, and reduce runoff and water discharge via infiltration, filtration, evaporation, and flood detention to realize effective hydrological design (Bhatt et al, 2019). Such measures as "bioretention," "green roofs," and "permeable pavement" are taken to simulate the hydrological process of nature.…”

Green infrastructure can effectively coordinate environmental, social and economic development, and has become one of the important strategies to achieve sustainable development. This study used CiteSpace and VOSviewer to analyze 2194 papers in the field of green infrastructure published from 1995 to 2019 in the Web of Science database using the bibliometrics and visualization methods. Results demonstrate a substantial increase in the number of studies on green infrastructure in recent years, with European and American countries leading the study of green infrastructure. Landscape and Urban Planning, Urban Forestry & Urban Greening, and Journal of Environmental Management are the first three cited journals in green infrastructure study. By studying co-cited literature, the study of green infrastructure has been found to involve the relationship between green infrastructure and ecosystem and human health, construction, evaluation and management of green infrastructure, and analysis of a special aspect of green infrastructure, among others. Clustering analysis results of green infrastructure keywords indicate that the existing studies have concentrated on green infrastructure in stormwater management, ecosystem services, biodiversity protection, and climate change. This study provides references for green infrastructure for sustainable environment development.
