“…The concept of ISI was further applied by the authors for quantitatively examining the impact of industrial symbiosis on sustainability for a chemical industry. 27 The ISI is a simplified tool, which represents the socioeconomic benefit of any type of industry per unit of its carbon emissions. Carbon emissions could be direct and indirect.…”

The aluminum consumption in India of 2.5 kg per capita is way below the global average of 11 kg per capita. In the future, India will require additional annual consumption of 16 million tons of aluminum. Due to the energy-intensive nature of aluminum production coupled with its projected growth, there are sustainability concerns for this industrial sector. This paper examines some opportunities available for sustainability improvement in an existing aluminum plant using coal-based electricity. An industrial sustainability index (ISI), as previously developed by the authors, is here to quantitatively evaluate the magnitude of sustainability improvement through a natural gas-based combined cycle (NGCC) power generation. Two modes of sustainability improvement are examined: (a) NGCC with surplus power generation and (b) NGCC with doubling of production capacity. It is observed that the ISI values can be increased by 5 to 6 times through the above modes, as compared to the existing model.The investment required for such sustainability improvement is expected to be less than that required for setting up a totally new plant. The direct carbon emissions for the existing plant are nearly 6.4% of the total carbon emissions, which may be eliminated by adopting new smelting technology now available, with the further possibility of sustainability improvement.

“…Emerging from academia are new quantitative models designed to measure different aspects of industry, from individual enterprises or scaling up more broadly to be applied to precinct-based collectives. One such model produces an index which is a measurement of the extent to which three sustainability goals (social, economic and environmental) as they relate to enterprises and their products, are impacted by IS (Pandey & Prakash, 2019). As described earlier, IS and its foundation in relationships has been evolving in the industrial setting for decades.…”

The traditional definitions of Industrial Symbiosis broadly describe it as a symbiotic relationship between enterprises usually operating in close geographic proximity within an industrial precinct where the reduction of waste and by-products through re-use of these materials is the goal, and is more recently described within the broader construct of Circular Economy. But there is more to a successful industrial precinct than simply the business-to-business relationships associated with these by-product material exchanges. The literature is slowly beginning to explore the presence of various forces that also have a role to play. The novelty of this research is that these forces have been explicitly identified as being a mix of four relationship-based synergies. These were identified and crystallized through a series of four sequential papers, and provisionally grouped under four headings, or dimensions; Materials Exchange, Skilled Workforce, Support Industry, and Governance. The purpose of the research was to develop a model which could be used to create a dimensional profile for any given industrial precinct. For each of these dimensions, a set of five influencing factors were identified, and collectively they were used to build a profile for a given industrial precinct. Analysis of the dimensional influencing factors was expected to deliver insights into the extent to which they may or may not be impacting the performance of the enterprise actors located within it. Respondents from four distinct groups associated with the precincts (policy makers, precinct managers, enterprise managers and representative groups) were selected for the research and were asked to characterise their precincts by rating each set of dimensional influencing factors. The major finding of the research was that the reason for the relative strength or weakness of an industrial precinct can be described under this four-dimensional framework which has been called the KIC4 Model of How to cite this paper: Oughton, C.,

An eco-efficiency analysis has been conducted, as a sustainability performance indicator, by combining the life cycle costs (LCC) and the environmental impacts of diverse plasma-assisted ammonia and nitric acid synthesis routes, for which a detailed process design for small-scale production has been previously reported. The proposed design of the specific plasma processes involves new upstream and downstream activities, which are independent of conventional natural resources and comprise less equipment. In the context of this study, the impact of the product yield and plasma power consumption on the eco-efficiency profiles of the selected plasma processes is evaluated and benchmarked against that of the established synthesis pathways. Results show a relatively improved environmental profile of the plasma-assisted NH3 (5% NH3 yield), considering a power consumption of 17.2 g NH3 kWh−1 and energy recovery of 5%, against that of the contemporary production route. In the case of the plasma-assisted HNO3 (6% NO yield) synthesis, incorporating a power consumption of 7.77 kWh kg−1 NO and a 20% energy recovery, a better ecological footprint is displayed as compared to the conventional chemical process. Both plasma processes are characterized by higher LCC than the conventional ones, with the plasma-assisted nitric acid displaying a more competitive LCC profile. A clear contribution of the utilities (upstream and downstream equipment) to both the environmental and cost benefits is shown, and the plasma plant is the enabler of such integration. The contribution is related to both the number reduction of equipment (process simplification) and improved operation (process intensification). Given the outcomes of this study, the concept of developing modular plants incorporating the plasma technology and renewable energy sources—e.g. wind power—for synthesizing ammonia and nitric acid demonstrates promising potential and promotes a new window of opportunities for future sustainable decentralized fertilizer production; such as distributed production at the farm site, with the opportunity to react immediately to weather changes and to local conditions (soil, climate, crops, farming business model).
