Nowadays, in all sectors we are dealing with an intense development of technology, necessary on the one hand for our everyday lifestyle, but however with a major impact on the environment due to the lack of a proper infrastructure. In the case of electrical and electronic equipment waste (WEEE) management, due to their volume and composition, further expertise is needed for the collection and processing of electronic waste in an ecological way. Although different laws are adopted at national and international level, many illegal practices are registered among producers, consumers and stakeholders for the end-of-life of WEEE management. The purpose of this study is to raise the awareness of stakeholders regarding the assurance of sustainable development, by reducing the impact on the environment and natural resources conservation, following the best practices recommended for an eco-friendly management. Through this paper, useful strategies applied in several developed countries for the management of WEE have been studied and analyzed, and future perspectives regarding the management of electronic waste (e-waste) are suggested. In addition, human population should be more conscious regarding the significance of handling and recycling of WEEE..

This study presents the results of the investigation of the deposition of various chemical elements in the air using mosses as biomonitors in the Crn Drim River Basin, North Macedonia. For this purpose, 41 moss samples were collected using a previously adapted sampling network. The content of 60 elements was determined by atomic emission spectrometry - inductively coupled plasma (ICP-AES) and inductively coupled plasma - mass spectrometry (ICP-MS). Nineteen elements (Al, Ba, Ca, Cd, Cr, Cu, Fe, K, Li, Mg, Mn, Na, Ni, P, Pb, Sr, Tl, V, and Zn) were analysed using ICP-AES, while the remaining twenty-nine (Ag, B, Bi, Br, Ce, Co, Cs, Dy, Er, Eu, Ga, Gd, Ge, Hf, Ho, I, La, Mo, Nd, Pr, Rb, Sc, Sm, Sn, Tb, Ti, Y, Yb, and Zr) were analysed with ICP-MS. Multivariate statistical analysis was applied to the present data. Factor analysis applied to the result from ICP-AES yielded 3 geogenic factors: Factor 1 includes Cd, Cu, K, and Zn; Factor 2 includes Ba, Mn, and Sr, and Factor 3 includes Al, Cr, Fe, Li, Mg, Ni, and V. Among the correlation factors of all analysed elements, two groups of elements show similar distribution: G1 (B, Ba, Ca, Cd, Dy, Er, Ga, Ge, Mg, Mo, Nd, Ni, Pb, Tb, Tl, V, Zn, and Zr) and G2 (Al, Br, Cr, Cu, Gd, Ho, I, K, Mn, P). The data obtained and the distribution maps for each element and the factors and groups indicate a lithogenic occurrence of the elements and low concentrations of potentially toxic elements in the study area.

Obtaining a comprehensive understanding of green management in the pharmaceutical industry is important in developing countries to inform policymakers, minimize the industry’s environmental impact, protect public health, reduce costs, and improve the reputation of pharmaceutical companies. Tailored solutions are needed to address environmental challenges in developing countries, as their nature and incentives differ from those in developed countries. This study investigates the current state of green management in the pharmaceutical industry in Iran, providing insights into incentives and practices that can inform effective environmental policies in developing countries. This research employed a two-phase approach, beginning with a descriptive cross-sectional study. The study surveyed managers from 53 of Iran’s 100 active pharmaceutical factories to gain insight into current green management practices. Following this, a qualitative study was conducted to extract and hierarchically prioritize the internal and external incentives for improving sustainable practices within these factories. The study’s findings revealed that nearly 70% of the surveyed companies had implemented regulatory requirements, including facility inspections. However, implementing green management principles, such as reducing fossil-fuel consumption, was observed in less than 30% of the companies. The results indicate that Iranian companies prioritize machine performance over environmental concerns, as evidenced by their focus on repairing and improving their equipment.

In this study, silica nanoparticles (SiNPs) have been synthesized from waste source such as rice husk (RHs) and wheat husk (WHs) by using method such as acidic hydrolysis, oxidation with KNO3 and KMnO4, and pyrolysis. The purpose of this research was to reduce agriculture waste and reduce humans’ ecological footprint. The synthesized SiNPs were used to create bio-nanocomposite sheets with various concentration of silica using a casting method, which could be used in food packaging instead of plastic, which is harmful to the environment and humans. The effect of nano-silica from RHs and WHs on the physical properties of nanocomposite sheets was investigated. Results showed that the nanocomposite sheet with 0.2 g WHs has the highest tensile strength, and the strength increased with increasing concentration, which is due to the presence of intermolecular interactions between silica and starch in the blend films. Water absorptivity of 0.2 g WHs with highest tensile strength decreased due to the addition of silica content. The results indicated that 0.2 RHs films had the highest water absorption at 49.4% after one hour of immersion, while 0.2 WHs films had the lowest absorption at 39.8% which is due to the network structure created by combining silica and starch plastic films. The synthesized SiNPs and bio-nanocomposites were characterized by using FTIR, SEM, XRD, UTM and particle size analyzer. By considering the results of the bio nanocomposites, they can be recommended for food packaging applications.
本研究以稻壳和小麦壳为原料，采用酸性水解、KNO3和KMnO4氧化、热解等方法合成了二氧化硅纳米颗粒。本研究旨在减少农业浪费，减少人类的生态足迹。将合成的SiNPs用浇铸法制备了不同浓度二氧化硅的生物纳米复合材料片，可以代替对环境和人体有害的塑料，用于食品包装。研究了RHs和WHs中纳米二氧化硅对纳米复合材料片材物理性能的影响。结果表明，当WHs浓度为0.2 g时，纳米复合膜的拉伸强度最高，且强度随浓度的增加而增加，这是由于共混膜中二氧化硅与淀粉之间存在分子间相互作用。抗拉强度最高的0.2 g WHs吸水率随着二氧化硅含量的加入而降低。结果表明，浸泡1 h后，0.2 RHs膜的吸水率最高，为49.4%，而0.2 WHs膜的吸水率最低，为39.8%，这是由于二氧化硅与淀粉塑料膜结合形成的网状结构所致。采用FTIR、SEM、XRD、UTM和粒度分析仪对合成的SiNPs和生物纳米复合材料进行了表征。考虑到生物纳米复合材料的结果，它们可以推荐用于食品包装应用。

Ash and slag waste present a significant environmental threat on a global scale, requiring an international solution. Extensive analysis has revealed the potential utilization of waste from fuel and energy complexes across various sectors. Notably, fly ash derived from ash and slag waste generated by thermal power plants in China has emerged as a widely employed material. This fly ash can be further processed to extract fibers, which find applications in numerous industries. In China, fly ash from thermal power plants serves as the primary source for producing nano-tubes. These nano-tubes are utilized as additives in cement-concrete mixtures, as well as in the manufacturing of ceramic products and heat-insulating materials. Additionally, the fiber obtained from fly ash in Chinese thermal power plants has found extensive use in road and airfield construction. Its incorporation enhances the operational and economic performance of various road construction projects. The utilization of recycled fly ash in both cold and hot road paving techniques not only enhances operational properties but also improves strength indicators. Overall, the analysis from this paper demonstrates the significant potential for utilizing waste materials from fuel and energy complexes, with particular focus on fly ash from thermal power plants in China. The subsequent extraction of fibers and the manufacturing of nano-tubes hold promise for various applications in cement-concrete mixtures, ceramic products, heat insulation, road construction, and airfield development. These advancements not only contribute to improved operational and economic efficiency but also enhance the strength characteristics of the materials employed.
