Cosmetic industry is one important sector in the global economy and expected to grow next years. The need achieve Sustainable Development (SD) growing as well, cosmetic companies are looking for innovative sustainable solutions aimed at reducing their negative environmental, economic social impacts. interest this field also regards scientific community which investigates proposes Circular Economy (CE) a paradigm could support transition towards future. In context, study aims analyze, through bibliometric systematic literature review, state of art CE by exploring academic studies from different perspectives, such object proposed solutions, research methods applied, 4Rs principles inspiring practices. addition, link between circular practices sustainability investigated. analysis permits classify into four categories: input valorization, packaging solution, output governance management. main results show that highest attention focused on valorization formulation products. regard, agri-food chemical sectors emerges due high number waste by-products. On other hand, options less investigated among community. Finally, category management highlights importance strategies not only production phase, but organizational level, example proposing specific business models. highlight existence circularity concept, specifically focusing environmental dimension.

Plastic waste pollution is a challenging and complex issue caused mainly by high consumption of single-use plastics the linear economy "extract-make-use-throw". Improvements in recycling efficiency, behaviour changes, circular business models, more precise management system are essential to reduce volume plastic waste. This paper proposes simplified conceptual model for smart separation based on sensor technology deep learning (DL) facilitate recovery recycling. The proposed could be applied either at source (in bins) or centralised sorting facility. Two systems have been investigated: i) one utilising 6 sensors (near-infrared (NIR), humidity, temperature, CO2, CH4, laser profile sensor) ii) with an RGB camera separate packaging materials their composition, size, cleanliness, appearance. Simulations case study showed that camera-based sorting, Inception-v3, DL convolution neural networks (CNN), achieved best overall accuracy (78%) compared ResNet-50, MobileNet-v2, DenseNet-201. In addition, resulted higher number misclassified items bins, as it focused solely appearance rather than material composition. Sensor-based faced limitations, particularly dark colouration organic matter entrapment. Combining information from cameras potentially mitigate limitations each individual method, thus resulting purity separated fractions.

Planning is a form of interaction between social, economic, environmental, political, organizational, and institutional elements that undergo different processes. influenced by sets subsets factors come together are measured on spatial scale. Despite well-planned strategies, sustainability has always been questioned, especially in developing countries. In this regard, the Circular Economy concept considered an inclusive solution to contemporaneous phenomena model for ensuring any initiative. Albania undertook territorial reform decentralization 2014, all national regional strategies were drafted considering closed-cycle concepts. As such, was central point focus plans.

Naturally abundant materials play a crucial role in the development of sustainable electrochemical energy storage (EES) devices including batteries and supercapacitors (SCs). This is due to limited available resources with regards materials, environmental pollution produced by toxic utilized conventional EESs. In current review, field natural bast fibres (jute, flax, hemp kenaf) based EES performances highlighted. review emphasizes methods such as direct use modified activated carbon from biomass for design devices. Activated were developed using both physical chemical activation methods. Key challenges active electrode preparation, capacitive retention, implementation fibre are critically discussed. Furthermore, recent surge wearables portable technologies that demand further flexible/non-flexible also explored. Future trends perspectives on development, power management interface, recycling, biodegradability circular economy addressed. It concluded new renewable systems has many remarkable advances device performance. For this, an innovative approach required develop high density which will be potentially implemented clean solutions.

Escalating industrial CO2 emissions necessitate innovative carbon capture and utilization strategies. This study explores the potential of mineral-carbonation steelmaking slags, particularly White Slag (WS) various Refractory Wastes (RWs), to mitigate valorize wastes. Experiments were performed with waste materials from production lines at CELSA (Barcelona, Spain). We delved into direct aqueous carbonation, evaluating performance characteristics these wastes under different experimental conditions. Our findings reveal that all slags can effectively sequester CO2. process is effective not only for pure but also diluted flue gases mild conditions (≤ 100 ºC, ≤ 6 bar). Specifically, WS exhibited peak sequestration capacities (SC) 359.79 gCO2/kgslag (pure CO2) 276.65 (diluted gas). In contrast, RWs presented kinetic, reaching a maximum SC 311 after prolonged times. Given large inhomogeneity RWs, individual analysis distinct RW fractions revealed significant variations in carbonation performance. Tundish highest capacity, emphasizing importance source mineral composition carbonation. Chemical morphological evaluations confirmed transformation CaO CaCO3, MgO remaining largely inert. Additionally, indicated environmental benefits by reducing mobility toxic metals, Pb, suggesting an ancillary avenue treatment. underscores utility mineralization as dual-benefit approach within circular economy framework, offering insights its application sustainable management emission reduction steel industry.

The circular economy and the clean-energy transition are inextricably linked interdependent. One of most important areas energy is development hydrogen energy. This study aims to review systematize data available in literature on environmental economic parameters storage transportation technologies (both mature at high technological readiness levels). concluded that salt caverns pipeline promising methods today terms a combination all parameters. These competitive price, especially when transporting over short distances. Thus, average price will be 0.35 USD/kg, distance up 100 km 0.3 USD/kg. Hydrogen underground gaseous state its by pipelines have least consequences for environment: emissions leaks insignificant, there no pollution. identifies these as particularly viable given their lower impact potential seamless integration into existing systems, therefore supporting more sustainable economy.

Abstract This paper investigates whether and to what extent circular economy performance affects the financial of a global sample listed agri‐food firms. Furthermore, potential moderating role stakeholder engagement in empowering this relationship has been tested. A index developed based on Environmental Social Governance scores reclassified light reuse, reduce, recovery recycling (4R) paradigm. Then, multivariate regression model from 2015 2022 carried out. broader theoretical framework adopted, combining natural resource‐based view theory. The results show positive between performance, boosting function played by engagement. study findings provide stimuli for academics managers reflect profitability pivotal giving significant impulse transition.
