“…Energy integration could also lead to beneficial environmental savings by increasing energy efficiency, and thus reducing the external energy demand. Furthermore, detailed exergy analysis can help to improve the overall energy efficiency of the process [690] and there are good examples of this for other processes in the literature [691][692][693][694][695][696]. Furthermore, biomass fractionation, into relatively high concentration streams of cellulose, hemicellulose, and lignin, may provide an opportunity to reduce the costs.…”

“…By crosslinking data available in the literature, the energy per unit of the sterilizing agent mass needed for the whole treatment process can be estimated to be around 80 kWh/kg. [33][34][35] The corresponding energy consumption evaluated for the proposed method, based on the nonthermal plasma indirect treatment, is 29.6 kWh/kg. This value must be increased tacking into account the cooling system energy consumption, synthetic air production, and carton pretreatment.…”

Nowadays, the majority of the processes used to sterilize disposable medical devices have several drawbacks in terms of safety, energy consumption, and costs. In this work, a sterilization method based on an indirect nonthermal plasma treatment is presented. The main advantages of this method are low environmental impact, absence of harmful chemical compounds' storage, and backward compatibility relative to production, sterilization, and shipping chain. The sterilization of disposable devices, enclosed inside their protective packaging, is achieved by exploiting reactive species produced by a Dielectric Barrier Discharge plasma reactor. Various devices have been subjected to a 2‐h treatment, achieving complete sterilization based on USP and EU‐PHARMA protocols. Pretreatment of carton packaging has been necessary to guarantee a complete sterilization process.

“…[77] As noted earlier, Thasai & Siemanond [57] had observed that while pinch analysis focuses on heating and cooling, exergy analysis factors in work as well. In the case of Ghannadzadeh & Sadeqzadeh, [78] which adopts the same approach as the former to study the hot and cold streams of a chlorine-caustic soda production process, CPEA suggested a possibility of raising the hot utility requirement slightly by 430 kW (from 7.74 MW to 8.17 MW), while reducing the cold utility demand considerably by 97% (from 13 MW to 400 kW), resulting in a net reduction in energy use.…”

Pinch analysis, as a technique to optimise the utilisation of resources, traces its beginnings to the 1970s in Switzerland and the UK ETH Zurich and Leeds University to be more precise. Over four decades down the line, this methodology has entrenched itself in research circles around the world. While the technique was developed, to begin with, for energy (heat) recovery, it has since then expanded to embrace several other fields, and enabled optimisation of resource utilisation in general. The motive behind this article is to perform a focused, selective review of recent case studies from the developing world and transition economies, having 'pinch analysis' in their titles and thereby as their 'core, crux and gist', during the period 2008-2018. The resources focused on, include heat energy, electrical energy, water, solid waste, money, time, land (surface area), storage space (volume), human resources, mass of resources in general and hydrogen, while a handful of publications have their focus on carbon dioxide (greenhouse gases in general) emissions. Multi-dimensional pinch analysis promises to be an effective tool for sustainability analysis in the years to come; most importantly in the developing world where social well-being and economic development are priorities in the years ahead, and they ought to be attained by a simultaneous truncation of the environmental footprint, in other words, an optimisation of resource utilisation as well as adverse environmental impacts. In other words, the focus ought to be on sustainable production (efficiency) and consumption (sufficiency).
