“…Last but not least, LCA practice was also initiated in many other areas and published in the International Journal of LCA: Yuan et al (2013) evaluated the life-cycle environmental impacts of the textile-dyeing industry and identified key processes for mitigating life cycle environmental impacts; Xie et al (2013) estimated the environmental impact of commonly used treatment of composite packaging waste to determine an optimal waste management strategy and design new separating and recycling technology for composite packaging; Hong et al (Hong and Li 2012) carried out LCAs to estimate the environmental effects of pentachloroaniline biodechlorination under acidogenic/methanogenic conditions through laboratory scale experiments; Song et al (2013) performed LCAs to investigate the environmental performance of PCs in Macau. We would like to encourage Chinese authors to submit their research results to future issues of this journal.…”

“…Now, more than 10 years later, there has been remarkable progress with many publications on different subjects. Current research in China covers a lot of areas including regional life cycle impact assessment (LCIA) methodology of abiotic resources (Gao et al 2009a, b, c), land use (Liu et al 2010), the Chinese life cycle inventory (LCI) database (Gong et al 2006), as well as typical case studies such as power generation (Di et al 2007), iron and steel (Li et al 2002), magnesium (Gao et al 2009a, b, c), construction (Wu et al 2012), continuous pad-dyeing technology for cotton fabrics (Yuan et al 2013), aseptic packaging waste management (Xie et al 2013), desktop personal computers (PCs) (Song et al 2013), polymers (Hong and Li 2012), titanium (Liao et al 2012), and so on. In addition, a symposium focused on materials LCA (MLCA) and ecomaterials has been held biennially in China as part of the IUMRS international conference on advanced materials.…”

“…Early LCA studies focused mainly on ex situ remediation methods, while in more recent years, LCAs for in situ remediation technologies have been published. Recent in situ remediation LCAs include comparative studies of permeable reactive barriers versus pump and treat (Higgins et al, 2009;Mak & Lo, 2011), capping options for sediment remediation (Sparrevik et al, 2011); electron donors for in situ bioremediation applications (Hong & Li, 2012); and in situ bioremediation versus in situ thermal desorption versus excavation and disposal (Lemming et al, 2010b).…”

A detailed cradle-to-grave life-cycle assessment (LCA) of an in situ thermal treatment remedy for a chlorinated-solvent-contaminated site was performed using process LCA. The major materials and activities necessary to install, operate, monitor, and deconstruct the remedy were included in the analysis. The analysis was based on an actual site remedy design and implementation to determine the potential environmental impacts, pinpoint major contributors to impacts, and identify opportunities for improvements during future implementation.The Electro-Thermal Dynamic Stripping Process (ET-DSP TM ) in situ thermal technology coupled with a dual-phase extraction and treatment system was evaluated for the remediation of 4,400 yd 3 of tetrachloroethene-and trichloroethene-impacted soil, groundwater, and bedrock. The analysis was based on an actual site with an estimated source mass of 2,200 lbs of chlorinated solvents.The remedy was separated into four stages: remedy installation, remedy operation, monitoring, and remedy deconstruction. Environmental impacts were assessed using Sima Pro software, the ecoinvent database, and the ReCiPe midpoint and endpoint methods.The operation stage of the remedy dominated the environmental impacts across all categories due to the large amount of electricity required by the thermal treatment technology. Alternate sources of electricity could significantly reduce the environmental impacts of the remedy across all impact categories. Other large impacts were observed in the installation stage resulting from the large amount of diesel fuel, steel, activated carbon, and asphalt materials required to implement the technology. These impacts suggest where opportunities for footprint reductions can be found through best management practices such as increased materials reuse, increased recycled-content materials use, and clean fuels and emission control technologies. Smaller impacts were observed in the monitoring and deconstruction stages. Normalized results show the largest environmental burdens to fossil depletion, human toxicity, particulate matter formation, and climate-change categories resulting from activities associated with mining of fossil fuels for use in electricity production.In situ thermal treatment can reliably remediate contaminated source areas with contaminants located in low-permeability zones, providing complete destruction of contaminants in a short amount of time, quick return of the site to productive use, and minimized quantities of hazardous materials stored in landfills for future generations to remediate. However, this remediation strategy can also result in significant emissions over a short period of time. It is difficult to quantify the overall value of short-term cleanups with intense treatment emissions against longer-term cleanups with lower treatment emissions because of the environmental, social, and economic trade-offs that need to be considered and understood. LCA is a robust, quantitative tool to help inform stakeholder discussions related to the remedy sele...
