“…The life cycle approach can be good when applied to the dry and wet grinding processes. Rossmann et al [20] discussed the analogy of LCAs and the basic role of its application. They proposed that a life cycle assessment study should provide concrete and transferable results.…”

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.

“…Policymakers, technology assessors, and scientists should be aware of conventions and habits about the contingent selection of models and data employed to make future statements. Besides, responsible research should reflect the intended application of published studies as powerful props with respect to contingent future narratives and their use in present power constellations (Roßmann et al 2020;Saltelli and Di Fiore 2020). However, since imagining the future, reflecting on considered beliefs, and practical action are materially and socially embedded, iterative practices, the rational deliberation about the future must not be overemphasized (Emirbayer and Mische 1998, 963).…”

Life cycle assessments (LCA) approaches, analysing potential impacts associated with the production and use of biomass for energy and material purposes, have become increasingly important in recent years. An internal project at the Deutsches Biomasseforschungszentrum- DBFZ is investigating, which priority areas have been addressed at the institute with LCA. The preliminary results of the study show mostly practice-linked applications with a focus on the assessment of fuels, their production and technical feasibility. In this publication, we present one of the studies analysed, in which a simplified LCA approach defined in the renewable energy directive (RED II), was applied. Based on primary data from 10 biogas and biomethane supply chains in Germany, the applicability of the RED II greenhouse gas (GHG) emission calculation approach was analysed. Most of the biogas plants assessed were found to be compliant with the required minimum GHG emissions reduction. Storage of digestate, N-fertilization and the use of fossil diesel were identified as the main factors, influencing the GHG intensity of the respective value chains. Additionally, individual calculation requires a high effort for data collection. The availability of tools and default values could therefore support market actors with an efficient implementation of the RED II.
