The challenge of assessing emerging technologies with life cycle assessment (LCA) has been increasingly discussed in the LCA field. In this article, we propose a definition of prospective LCA: An LCA is prospective when the (emerging) technology studied is in an early phase of development (e.g., small-scale production), but the technology is modeled at a future, more-developed phase (e.g., large-scale production). Methodological choices in prospective LCA must be adapted to reflect this goal of assessing environmental impacts of emerging technologies, which deviates from the typical goals of conventional LCA studies. The aim of the article is to provide a number of recommendations for how to conduct such prospective assessments in a relevant manner. The recommendations are based on a detailed review of selected prospective LCA case studies, mainly from the areas of nanomaterials, biomaterials, and energy technologies. We find that it is important to include technology alternatives that are relevant for the future in prospective LCA studies. Predictive scenarios and scenario ranges are two general approaches to prospective inventory modeling of both foreground and background systems. Many different data sources are available for prospective modeling of the foreground system: scientific articles; patents; expert interviews; unpublished experimental data; and process modeling. However, we caution against temporal mismatches between foreground and background systems, and recommend that foreground and background system impacts be reported separately in order to increase the usefulness of the results in other prospective studies. Keywords:case study emerging technology industrial ecology life cycle assessment (LCA) prospective technological changeConflict of interest statement: The authors have no conflict to declare.

“…Owing to their biochemical and catalytic properties, laccase are considered as good green biocatalysts, potentially exploitable for in-field uses: they indeed mediate versatile reactions, being thermostable with a long shelf-life even at room temperature (Youshuang et al, 2011;Liu et al, 2013). Treatments based on these enzymes have been successfully applied towards many xenobiotics including EDCs (Cabana et al, 2007a;Manda et al, 2014). However mostly model single-component solutions have been tested (Catapane et al, 2013;Hommes et al, 2012;Murugesan et al, 2010).…”

a b s t r a c tThis study describes a multidisciplinary approach that investigates the breakdown potential of a laccase mediated system from Trametes pubescens MUT 2400 against several micropollutants including already recognized endocrine disrupting chemicals at their natural residual concentrations (from mg/L up to ng/ L).In model solution, the chemical speciation focused on a mixture of 18 analytes and adopted stir bar sorptive extraction with directed in-situ derivatization followed by gas chromatography and mass spectroscopy analysis. The method's key performance parameters were evaluated in consideration of the chemical peculiarities and complexity of real wastewaters: precision, accuracy, estimated working range extended to a wide residual concentration interval (10 ng/L to100 mg/L) indicated its fitness for purpose. Laccases were extremely active towards all the target compounds, both in term of removal yields and rate. The maximal percentage of removal was obtained for 4-t-butylphenol, 2-hydroxybiphenyl, 4-noctylphenol, salicylic acid and estrone (percentage of removal above 90%). Enzymes concentration played a central role and in most of the cases, the catalyzed reactions were very fast: the initial concentration of 9 compounds was halved within the first 3 h.The laccase-mediated treatment was then applied to a municipal wastewater collected in a real wastewater treatment plant, containing at least 9 xenobiotics as drugs, pesticides, plasticizers and personal care products. Although the harsh chemical and biological conditions of the effluent influenced enzyme stability, the reaction took place, and above 70% transformation was obtained for most analytes during the 24 h experiment. Bioassays were carried out to estimate the estrogenic activity (the E-screen test and the MELN gene-reporter luciferase assay) and the ecotoxicity (Lepidium sativum, Pseudokirchneriella subcapitata and Vibrio fischeri), demonstrating the capability of laccases to mediate an effective detoxification of the wastewater and a decrease of the estrogenic activity. treatment plant; U/L, enzymatic activity expressed as International Unit per liter; PR, percentage of removal; MEC, minimal effective concentration; t 1/2 , analyte half-life; Ti, Target Ions; RSD%, relative standard deviation percentage; LOQ, limit of quantification; QCx, quality control samples; Rel.Err %, relative error percentage; COD, chemical oxygen demand; GI%, germination index; I%, inhibition percentage of the algal growth or of the bacterial bioluminescence; EEQ, 17-b-estradiol equivalent quantity; RPE %, relative proliferative effect; TRANS%, rate of luciferase gene expression.
