“…Thus, to assess environmental sustainability of the IL pretreatment process, eco‐footprint assessment was used in this study. The eco‐footprint was defined and formulated by Leseurre et al . to understand the sustainability of the biochemical process.…”

“…These indicators are broadly divided into two groups namely: (i) manufacturing footprint, which includes water consumption (H 2 O), raw materials geographical origin (iL), aqueous waste valorization (eFA), used organic solvents valorization (slOS), and process carbon footprint (eC); and (ii) eco‐design footprint, which includes synthetic pathway efficiency (eVS), raw material of renewable origin (rMP), E‐factor (eF), potential environmental impact of raw materials (ieMP), and potential environmental impact of waste (ieD). All of these indicators are known as the eco‐footprint and the details governing equations as well as descriptions of each factor can be obtained elsewhere . In summary, each factor has a minimum and maximum value of 1 and 4.…”

Pretreatment of biomass is essential to produce fermentable sugars, which can be further transformed into biofuels. Most of the common pretreatment methods, including sulfuric acid pretreatment, lead to low sugar yields and high microbial inhibitors formation, and require an additional detoxification step prior to fermentation. Ionic liquid (IL) pretreatment has the potential to reduce or eliminate these problems, and, thus, recently, has gained significant attention as an alternative pretreatment technology. However, before commercial deployment, IL pretreatment requires a thorough assessment of its techno‐economic feasibilities and bottlenecks. Thus, the main objective of this study was to assess the techno‐economic feasibility of a commercial‐scale IL pretreatment for a 113 million liter/year (30 million gal/year) cellulosic biorefinery and identify operational targets for process improvement. 1‐ethyl‐3‐methylimidazolium acetate IL was used for analyses, which is one of the mostly investigated ILs and is currently best at dissolving the lignocellulosic biomass. Corn stover, poplar, and switchgrass were used as the model feedstock. Input data were obtained from recent literatures on IL pretreatment of these feedstocks. Estimated sugar production costs ($/kg) from corn stover, switchgrass and poplar were 2.7, 3.2, and 3.0, respectively. IL recovery was identified to be the most sensitive parameter followed by IL cost and heat recovery. Furthermore, for IL pretreatment to be economically competitive with sulfuric acid pretreatment, >97% IL recovery, ≤$1/kg IL cost, and >90% waste heat recovery are necessary, all of which are very optimistic considerations at the present state of technology, thus requires further research and development efforts. © 2015 Society of Chemical Industry and John Wiley & Sons, Ltd

“…The lower the EF value is, the more environmentally friendly the industrial processes or population’s consumption in the area will be. In the evaluation of the EF six main ecological land-use categories are considered, i.e ., forest land, fishing ground, arable land, built-up land, grazing land and land used for energy production [5,6,7,8,9,10,11,12,13,14,15]. Currently, aside from general EF, specific EF for individual factors influencing ecosystems are becoming more popular.…”

Abstract:The concept of green chemistry is widely recognized in chemical laboratories. To properly measure an environmental impact of chemical processes, dedicated assessment tools are required. This paper summarizes the current state of knowledge in the field of development of green chemistry and green analytical chemistry metrics. The diverse methods used for evaluation of the greenness of organic synthesis, such as eco-footprint, E-Factor, EATOS, and Eco-Scale are described. Both the well-established and recently developed green analytical chemistry metrics, including NEMI labeling and analytical Eco-scale, are presented. Additionally, this paper focuses on the possibility of the use of multivariate statistics in evaluation of environmental impact of analytical procedures. All the above metrics are compared and discussed in terms of their advantages and disadvantages. The current needs and future perspectives in green chemistry metrics are also discussed.

Ultrasound-assisted extraction of rapeseed oil was investigated and compared with conventional extraction for energy efficiency, throughput time, extraction yield, cleanness, processing cost and product quality. A multivariate study enabled us to define optimal parameters (7.7 W/cm(2) for ultrasonic power intensity, 40 °C for processing temperature, and a solid/liquid ratio of 1/15) for ultrasound-assisted extraction of oil from oilseeds to maximize lipid yield while reducing solvent consumption and extraction time using response surface methodology (RSM) with a three-variable central composite design (CCD). A significant difference in oil quality was noted under the conditions of the initial ultrasound extraction, which was later avoided using ultrasound in the absence of oxygen. Three concepts of multistage cross-current extraction were investigated and compared: conventional multistage maceration, ultrasound-assisted maceration and a combination, to assess the positive impact of using ultrasound on the seed oil extraction process. The study concludes that ultrasound-assisted extraction of oil is likely to reduce both economic and ecological impacts of the process in the fat and oil industry.
