“…In the study by Prakash and Henham (2014) for Parag Dairy plant at Allahabad, Uttar Pradesh, India, they have proposed decentralized tri-generation system as a replacement to the conventional grid electricity based system. They have proposed "Combined Cooling and Heating Power (CCHP)" systems with three different configurations.…”

India is one of the largest countries in the world, with a population mainly living in villages and primarily engaged in dairy activities along with agriculture. Despite being the largest milk-producing nation, lives of local farmers are challenging due to the lack of access to technology in rural areas. This study aims to develop an integrated system that can solve the problems faced by farmers by utilizing locally available resources. Due to the time lag between milking and storage, milk spoilage is more likely to occur in remote areas. Immediate pasteurization and storage facilities are required. Heating and refrigeration are essential for pasteurization. In India, most villages face power shortages, so biomass heat is suitable for pasteurizing milk. A steam jet refrigeration system is also proposed as it runs with waste biomass for chilling milk. Steam required for both heating and chilling milk is generated in the same biomass-fired boiler. Also, make-up water requirements in the boiler are fulfilled using a rainwater harvesting system. In a conventional dairy plant, a cooling tower is used to supply condensate water required in the condenser. Here this water requirement is fulfilled using a bore well. Subsequently, this water is stored in the irrigation pond to cool it by natural cooling through surface evaporation, making the water suitable for irrigation purposes. Also, the payback period of this system is estimated to be less than six months. Looking at the multiple benefits, this integrated system will further facilitate in achieving sustainable development goals through rural development by 2030.

This paper quantitatively examines the impact of industrial symbiosis on sustainability. The quantitative approach, as developed by the authors, is based on the concept of Industrial Sustainability Index (ISI), which represents the socioeconomic benefit of an industry per unit of its carbon emissions. The ISI was evaluated for a chemical production plant both in independent and symbiotic modes with different energy technologies. The ISI value for the chemical production plant in independent mode was found to be 6 units. This was three times more than in the case of the existing symbiotic mode with an adjacent pulp & paper industry having coal fired CHP plant. With the adoption of more energy efficient technologies e.g. natural gas based combined cycle power plant and solar PV electricity generation; the ISI in the modified symbiotic mode can be increased to 18 units. The results indicate that industrial symbiosis can help in sustainability improvement when the technologies used by the industries are energy efficient.

“…For another process industry i.e. dairy industry in India, Prakash & Henham analyzed the energy benefits of grid-independent Combined, Cooling, Heating & Power (CCHP) systems, and reported primary energy savings (with commensurate carbon reduction) in the range of 20% -50% [10]. Such a study demonstrated that grid-independent co-generation sys- [15] with the help of different parameters and studied the industrial impact.…”

This paper proposes a new index for assessing sustainability of the industrial sector i.e. the Industrial Sustainability Index (ISI) and demonstrates its utility by applying it to an energy intensive industry. The proposed index incorporates all the three major dimensions of sustainability viz. economic, environmental, and social. It represents the socio-economic benefit of an industry per unit of its carbon emissions. The specific energy consumption or energy intensity (with commensurate carbon emissions), which is usually reported as a measure of environmental impact of various industries, does not include the social and economic parameters. The proposed ISI also overcomes the difficulties in assessing specific energy consumption such as allocation in case of multiple products and its variability with the type and scale of production. To illustrate, the proposed index has been evaluated for a typical paper industry in India. Further, opportunities for its improvement by fuel substitution and repowering through combined cycle power generation have been examined. With existing ISI of 16 units to an improved ISI of 78 units, approximately five times improvement in ISI was observed, indicating a potential for significant improvement in industrial sustainability through such measures.
