The effectiveness, efficiency, and productivity of the company are very much determined by the workload. By knowing the workload, a company can find out the optimum number of workers needed to meet the target. This is also important for the Indonesian Coffee and Cocoa Research Center, especially in the processing of coffee in the packaging section. Therefore a workload analysis will be carried out using the Work Sampling Method. From the results of the work sampling method, it can be seen that worker productivity is 0.90697, as well as a rating factor of 0.09 and an allowance of 22.With these results it can be calculated that the standard time needed by workers in coffee packaging is 10.98 minutes and the optimum number of workers required 2.06 people.

Due to the increasing demand for battery electric vehicles (BEVs), the need for vehicle battery raw materials is increasing. The traction battery (TB) of an electric vehicle, usually a lithium-ion battery (LIB), represents the largest share of a BEV’s CO2 footprint. To reduce this carbon footprint sustainably and to keep the raw materials within a closed loop economy, suitable and efficient recycling processes are essential. In this life cycle assessment (LCA), the ecological performance of a waterjet-based direct recycling process with minimal use of resources and energy is evaluated; only the recycling process is considered, waste treatment and credits for by-products are not part of the analysis. Primary data from a performing recycling company were mainly used for the modelling. The study concludes that the recycling of 1 kg of TB is associated with a global warming potential (GWP) of 158 g CO2 equivalents (CO2e). Mechanical removal using a water jet was identified as the main driver of the recycling process, followed by an air purification system. Compared to conventional hydro- or pyrometallurgical processes, this waterjet-based recycling process could be attributed an 8 to 26 times lower GWP. With 10% and 20% reuse of recyclate in new cells, the GWP of TBs could be reduced by 4% and 8%, respectively. It has been shown that this recycling approach can be classified as environmentally friendly.

Background: The use of tube-free insulin pumps is increasing. To protect the environment, the use of resources and the amount of emissions into the environment should be kept as low as possible when designing these systems. In addition to basic waste avoidance, the composition of the waste produced must be considered. Methods: To compare current tube-free pumps from an ecological standpoint, a tube-free insulin pump with a modular design and two non-modular tube-free pumps were subjected to manual separation, manual sorting, characterization, and mass determination. The annual waste volume of a user was measured, and the recyclability was assessed. The global warming potential (GWP) resulting from extraction of raw materials, energetic utilization of waste, and landfill of the incineration residues was balanced. Results: For the modular tube-free pump, a total waste volume of 5.5 kg/a (recycling percentage 44.3%) was determined. The non-modular systems generated 4.9 kg/a (recycling percentage 14.6%) and 5.1 kg/a (recycling percentage 16.0%) waste. The product-specific GWP of the modular system was approximately 50% lower than that of the non-modular systems; the packaging-specific GWP was 2.5 times higher. In total, a GWP of 13.6 kg CO2-equivalent per year could be determined for the modular system and a GWP of 15.5 kg CO2-equivalent per year for the non-modular systems. Conclusions: Although the modular micropump has a higher total waste volume, a greater ecological potential can be attributed to it. This is based on the recyclability of the system due to its modularity and the possible reduction of packaging waste.

The analysis of the current state of processing of secondary raw materials of wine-making in Ukraine is given. It is proved that the latter is a rich source of biologically active compounds, including phenolic ones, which makes it possible to use it for the production of a wide range of products (raccoon, polyphenol extracts, tartaric acid, beverages, fertilizers, grape oil, cake, vitamin D, animal feed, food powder, abrasives) with high consumer value for various industries: food, pharmaceutical, perfume and cosmetics, chemical, feed, etc. In the light of modern research, the role of phenolic compounds as essential nutrition factors that cannot remain out of the field of view of physiologists, pharmacologists, and food hygiene specialists is shown. However, currently in Ukraine there are no specialized enterprises for complex processing of secondary raw materials of winemaking; traditional technologies are not effective from a technological, economic and environmental point of view, which indicates not rational use of resources and loss of material resources; there are no systematic studies on physical and chemical, microbiological, Toxicological composition in order to determine the optimal direction of its use. A limiting factor is also the lack of comparative analysis of innovative domestic and foreign technologies for processing secondary raw materials of winemaking. In the vast majority of cases, in particular, combs and pomace are taken out of control to agricultural land without special treatment, which leads to acid soil erosion and pollution of the environment with metabolites of micromycetes, increasing one of the global problems of mankind-environmental. At the present stage of technological development, there are a number of innovative developments in the field of processing secondary raw materials, in particular grape pomace, in order to obtain biologically active additives, the limiting factor for the introduction of which is the lack of domestic and expensive imported equipment. A promising way to solve the existing problems is to create a mechanism that will unite the interests of wineries (producers of secondary raw materials of winemaking), processing enterprises (producers of products from secondary raw materials of winemaking), scientists and potential consumers of innovative products. Consolidation of the above-mentioned institutions and enterprises is possible by creating clusters for the development and implementation of innovative technologies and equipment

In a world depicted by rapid growth and consumerism, where pressing societal issues such as, the critical climate crises, resources exploitation in developing countries and much more, it is essential to educate all citizens about raw materials, their uses and about responsible production and consumption. Developing life-long learning wider society programmes is an essential tool to educate the population starting with the youngest members of society (pre-school) to adulthood (life-long learning) with a special focus on the life-world orientation from a learners’ perspective. The wider society learning flagship project, ‘Raw Matters Ambassadors at Schools’ (RM@Schools), is an innovative programme funded by the European Institute of Innovation & Technology (EIT) which promotes science education and careers in the raw materials sector. Since the project’s commencement in 2016, it has gained stronger European representation with a current total of 32 partners from 18 countries. This includes the consortium members from a parallel funded programme, RM@SchoolsESEE. This project aims at extending best practices and diversifying the current portfolio to East and Southeast European countries. What makes this project so innovative is in the programme and individual learning pathways. Considering a multidisciplinary and cultural perspective, a framework was developed to assist in forming raw materials ambassadors through engaging programmes for school pupils from aged 10 up to 19 years old and through the development of educational hands-on toolkits that range from experiments to game-based tools and much more. In particular, and as a way to increase impact, the project aims to mentor teenagers from all educational disciplines between the ages of 14–19 years old to become ‘Young RM Ambassadors’. This approach utilises state-of-the-art teaching and learning methods resulting in peer-to-peer knowledge exchange and dissemination. Built into the programme is a continuous feedback loop that involves stakeholders from all sides of the knowledge triangle: educators, pupils, professionals and researchers.


The most important characteristic of the economic activity of an industrial enterprise is the level of its financial standing. The higher this level, the more attractive is the company for shareholders, banks, service, raw materials and components buyers and suppliers, the more competitive its products are. In recent years, we have seen an unfavorable business climate both in Russia and around the world, which, on the one hand, forces some companies to cut costs or completely withdraw from the market, and on the other, it fosters companies’ attention to creative function, and not only in relation to the products being created, but also to the enterprise management model, the distribution and use of resources. In this connection, the possibility of using sourcing’s technologies in the issue of improving the financial stability of an industrial enterprise through the restructuring of its distribution model and the use of resources is of interest. To achieve this goal, we have used the sourcing’s maneuver model "higher utilization of production areas by providing outsourcing services". The development of proposals for improving the financial standing of the enterprise was carried out through the application of the "direct-hosting" system. In the present work, the authors developed proposals for improving the financial standing of an industrial enterprise through the application of the sourcing’s maneuver model. The results of this work can be useful for further scientific research in the field of economy of sourcing and development of the "direct-hosting" system. They can also be useful for managers of financial and economic units of large industrial enterprises. The developed proposals for improving the financial standing of an industrial enterprise through sorsing maneuver suggest the prospect of further scientific work in the field of forming methodological approaches for making managerial decisions.

Within integrated steelmaking industries significant research efforts are devoted to the efficient use of resources and the reduction of CO2 emissions. Integrated steelworks consume a considerable quantity of raw materials and produce a high amount of by-products, such as off-gases, currently used for the internal production of heat, steam or electricity. These off-gases can be further valorized as feedstock for methane and methanol syntheses, but their hydrogen content is often inadequate to reach high conversions in synthesis processes. The addition of hydrogen is fundamental and a suitable hydrogen production process must be selected to obtain advantages in process economy and sustainability. This paper presents a comparative analysis of different hydrogen production processes from renewable energy, namely polymer electrolyte membrane electrolysis, solid oxide electrolyze cell electrolysis, and biomass gasification. Aspen Plus® V11-based models were developed, and simulations were conducted for sensitivity analyses to acquire useful information related to the process behavior. Advantages and disadvantages for each considered process were highlighted. In addition, the integration of the analyzed hydrogen production methods with methane and methanol syntheses is analyzed through further Aspen Plus®-based simulations. The pros and cons of the different hydrogen production options coupled with methane and methanol syntheses included in steelmaking industries are analyzed.
