“…In general, a higher S/N ratio denotes an optimal level of the inuencing factor. 24,25 According to the contribution ratio and data in Fig. 8, the order of A4B4C3 (i.e., temperature of 70 C, sulfuric acid of 2.0 g, and a stirring speed of 110 rpm, respectively) was seen as the optimal combination of factors with respect to the yield.…”

“…A three‐level‐three‐factor of Taguchi design, one of the most healthy design and optimization technology which estimated the control factors separately to achieve the optimal design values(Chauhan et al, ), was applied for studying the effects of different preparation treatments of HASFs. Gelatinization methods (A): high temperature‐high pressure method, microwave heating method, and alkaline heating methods; starch concentrations (B): 2, 5, and 10%; and plasticizers (C): no plasticizer (water), glycerol, and xylitol (Table ).…”

“…For this purpose, in this article, an experimental design based on Taguchi method and analysis of variance (ANOVA) was applied. Taguchi method is one statistical approach pioneered by Dr. Genichi Taguchi (Chauhan, Singh, Kumar, Patnaik, & Thakur, ) and has been used extensively in many applications to compare different parameters. A balanced comparison of levels of the parameters and significant reduction in the total number of required test can be accomplished by adopting signal to noise (S/N) ratio and orthogonal array of Taguchi method (Sabrinas et al, ).…”

High amylose starch is a potential material to produce biodegradable films with the better physical properties than normal starch. In this research, Taguchi's design and analysis of variance were used to compare the effects of gelatinization methods, starch concentrations, and plasticizers on physical properties of high amylose starch films. The results showed that the gelatinization method was the most significant factor for transparency, and the highest transparency was obtained through high temperature‐high pressure treatment. The starch concentration impacted farthest on thickness, tensile strength, elongation at break, and solubility in oil. The highest thickness and tensile strength were obtained from 10% starch concentration, the highest elongation at break were created by 5% concentration, and the lowest solubility in oil was produced by 2% concentration. Solubility in water was affected by plasticizers most, especially in xylitol. The information in this study is helpful to choose optimal parameters for preparing high amylose starch films with desired physical properties. Practical applications Due to the biodegradable and environmentally‐friendly traits, high‐amylose starch film is a promising alternative to plastic film. Most studies were focused on the changing of one of the independent parameters at a time while maintaining the others at fixed levels. However, studying the interactive effects of these parameters is beneficial to the development of high‐amylose starch films at a whole insight. For this purpose, the effects of different preparation parameters under different levels on physical properties of high‐amylose starch film were studies under Taguchi design in this study. Results showed the different effects of gelatinization methods, starch concentrations, and plasticizers on different properties such as mechanical properties, solubility in water and oil, and transparency of high‐amylose starch films. The information provided by this study will play a guiding role for the production of high‐amylose starch films in different applications with optimal parameters.

“…Ultimately, the aim is to get a high return on embodied energy, emissions, and of course capital investment, from solar technologies. These aims have motivated researchers to continually improve the design and performance of solar collectors [26][27][28] and decrease their cost [29,30], and to understand their lifecycle environmental impacts [31,32]. Solar technologies have been assessed independently for their life cycle impacts [33,34], however, no studies in the literature have attempted to extrapolate this out for the environmental impacts of such solar technologies globally.…”

Global solar technology optimization for factory rooftop emissions mitigation

The industrial sector consumes ∼32% of the world's final energy demand, most in the form of heat which is derived primarily from fossil fuels. Two fundamentally different technologies exist for harvesting sunlight to offset fossil fuel use-solar thermal (ST) and photovoltaic (PV) collectors. The former convert sunlight into heat while the later convert sunlight directly into electricity (although electricity can be converted into heat via heat pumps and/or resistance heating). If/when factories transition towards utilizing their rooftops for solar harvesting, an essential question will be: which solar technology, or a mix of technologies, should be chosen for factory rooftops? This paper investigates this (as yet unanswered) question by assessing the global greenhouse gas emission (GHG e ) mitigation potential of PV and ST collectors in a side-by-side mix (e.g. a percentage where 0% is solely PV and 100% is solely ST available roof area coverage) to supply medium temperature heat (150°C-400°C) for industrial processes. It was found that in most locations globally, a mix of both technologies optimizes the solar output. Globally, installing the optimum PV:ST mix can save up to 141.8 or 205.8 kt CO 2e over installing solely PV or solely ST collectors, respectively. Another interesting finding of this study was that GHG e mitigation potential stems largely from where the solar collectors were manufactured (i.e. the embodied emissions from using local primary energy to fabricate the collectors). Thus, this study reveals that project managers, policymakers, corporate sustainability directors, etc could achieve maximum global GHG e mitigation through simply considering a mix of solar collector technologies and the best practices for manufacturing them.
