“…This life cycle assessment for the grinding production of different products takes into account the life cycle from the raw material transport to the manufacturer's gate (cradle-to-gate) in pharmaceutical, chemical, or ceramic industries. With the help of LCA results, an LCA-based model can be determined [28]. In case of the wet grinding process, carrying out an examination with a wider spectrum would also be necessary and in addition, recoverable energy attention should be paid to the emission.…”

Fine and ultrafine grinding of limestone are frequently used in the pharmaceutical, chemical, construction, food, and cosmetic industries, however, research investigations have not yet been published on the combination of energy and life cycle modeling. Therefore, the first aim of this research work was the examination of main grinding parameters of the limestone particles to determine an empiric energy-model. Dry and wet grinding experiments have been carried out with a Bond mill and a laboratory stirred ball mill. During the grinding processes, the grinding time and the filling ratio have been adjusted. The second goal of this research assessed the resources, emissions and environmental impacts of wet laboratory grinding with the help of life cycle assessment (LCA). The life cycle assessment was completed by applying the GaBi 8.0 (version: 10.5) software and the CML method. As a result of research, the determination of an empiric energy-model allowed to develop an estimated particle size distribution and a relationship between grinding fineness and specific grinding energy. The particle size distribution of ground materials can be exactly calculated by an empirical Rosin–Rammler function which represented well the function parameters on the mill characters. In accordance with LCA results, the environmental impacts for the mass of a useful product for different levels of specific energy with the building of approximation functions were determined. This research work sets up a new complex model with the help of mathematical equations between life cycle assessment and specific energy results, and so improves the energy and environmental efficiency of grinding systems. This research work facilitates the industry to make predictions for a production-scale plant using an LCA of pilot grinding processes.

“…A complete life cycle cost analysis may also include other costs, as well as other accounting/financial elements (such as discount rates, interest rates, depreciation, present value of money, etc.) (Cooper et al [8], Hsu [9]). The GaBi 5 LCA Software that largely encourages the research work came into the market in November 2011 and has several advantages for its former versions.…”

The persistent organic pollutants (POPs) waste take the main place in the group of organic industrial waste and the residues of the POPs waste generated in the processes of the chemical industry. There are green chemistry methods and some other treatment approaches for decreasing the quantity of the organic industrial waste, but currently thermic treatment processes are the most popular alternatives. This paper summarises thermic utilisation processes with a comparison between the different technologies, stressing factors affecting their applicability and operational suitability. The Life Cycle Assessment (LCA) can play an important role in such research. With the application of LCA for the Waste-to-Energy (WtE) technologies, their economic and environmental efficiency can be determined. Their advantages and disadvantages are examined in such a multi-component matrix. The LCA software GaBi 5 Professional is the basis for life-cycle impact assessment. The research can set up prognoses and models with LCA analyses and the conscious application of scientific methods, which can offer a prognosis for untested situations. While examining the above viewpoints, it worked out a new mathematical method which, in addition to the LCA, takes time and probability into consideration with the combination of a programming language, and which may mark a new direction for solutions and decision making in waste management. Despite the fact that chemical industry and environmental protection are closely interlocked, there is fairly poor national and international professional literature available about the two connected professions.

“…Implement a team approach called Value Management (VM), which uses an organized function-oriented system to analyze the cost and the function of the project system, equipment, or service to enhance its value [19,20]. Consider the selection of alternative materials, sustainability, and the cost-effectiveness of the selected materials [21,22]. Establish a recycling plan that includes provisions for collecting, disposal, and recycling project materials [23].…”

Numerous decision support systems have been developed to address the decision-making process in organizations. However, there are no developed mechanisms to track commitment down the line to the decisions made by corporate leaders. This paper is a portion of a study that establishes a framework for a comprehensive metric system to assess commitment to Sustainable Development (SD) decisions down the line in capital projects, and sets the groundwork for further development of performance indicators for SD outcomes. This ultimately leads to investigating the relationship between commitment to corporate decisions and better project performance in SD parameters. Hence, this study explores the literature to extract relevant parameters that reflect the degree of the project participants’ commitment to SD decisions and to develop commitment indicators. The study created then validated an index to track this commitment along the project stages: the Sustainable Development Commitment Tracking Tool (SDCTT). The SDCTT was tested on an infrastructure project case study. In this paper, techniques relevant to the first stage of projects (planning and definition) are presented. The SDCTT is the groundwork for the future development of performance indicators for SD outcomes, and within the postulated model should ultimately contribute towards reducing project waste, energy use, and carbon emissions.
