It includes online transactions across multiple sectors and technologies, such as the Internet, mobile technology, big data, and information and communications technology. The digital economy differs from a traditional economy because it relies on digital technology, online transactions, and its transformative effect on traditional industries Digital innovations such as the Internet of Things (IoT), Artificial Intelligence (AI), Virtual Reality, Blockchain, and autonomous vehicles all play a part in creating a digital economy. For this study, various papers on ”Digital Economy” and ”Industry 4.0” are identified from Scopus, Google Scholar and other research platforms and further studied briefly. This review paper has been developed after studying the digital economy and its needs in the Industry 4.0 Environment. The defining trends, key enablers, features and challenges associated with the digital economy towards Industry 4.0 are discussed briefly. Finally, the paper identifies and discusses the significant requirements of Industry 4.0 fulfilled through the digital economy. Today, customers are becoming aware of goods and services online and are turning to the industry for long-term solutions by deploying digital technologies. The digital economy is built on hyper connectivity, the growing interconnectedness of individuals, organisations, and machines due to the Internet, mobile technologies, and the IoT. Industry 4.0 technologies are automation, data exchange, cloud computing, robotics, big data, AI, the IoT, and other technological trends are all part of the industrial sector’s digital transformation, which aims to achieve industrial objectives and intelligent manufacturing practices that engage with customers, emerging technologies, and innovation. The economy is becoming more digital, changing how products and services are provided and consumed. A new road map is being provided by Industry 4.0 services to help many industries adapt their conventional methods and support the new revolution. In the digital economy, scaled-up, integrated ecosystems that leverage software platforms to generate value, build resilience, and stimulate innovation via networked goods, assets, people, and processes rapidly replace old, linear value chains with partner participation.</p></div>","PeriodicalId":100598,"journal":{"name":"Green Technologies and Sustainability","volume":"2 2","pages":"Article 100083"},"PeriodicalIF":0.0,"publicationDate":"2024-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949736124000101/pdfft?md5=83efcc03ed0f9208ffbece0251663a7e&pid=1-s2.0-S2949736124000101-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139985057","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current study investigates the influence of Industry 4.0 by assessing internal room parameters in an indoor ventilated room conditions for system output. Smart systems like AI and IoT, integrated with sensors, dynamically adjust indoor conditions based on external climate, enhancing HVAC system efficiency.

The study utilizes input parameters including Dry Bulb Temperature (DBT), Relative Humidity (RH), and Solar Radiation across diverse days to analyze system efficiency. ANN and RSM iteratively optimize system efficiency by training on RH, DBT, and air quality data. They converge on recommending 42% RH, 28 °C DBT, and 25 PM air quality, achieving 0.851 desirability. This approach enhances heat load (75.89%) and ventilation load (69.12%) efficiency significantly.

In this study, natural carbonation technology at a pilot scale was employed to mitigate the hazardous nature of WPFA by enhancing the stabilization of metal and metalloid trace elements (MMTE), particularly barium (Ba) and lead (Pb) leaching. Natural carbonation of WPFA was found to be optimal at a water/solid ratio of 0.3 L/kg under natural temperature and humidity conditions. Batch leaching tests based on thermodynamic equilibrium were used to assess MMTE solubility concerning pH in both non-carbonated and carbonated WPFA at natural pH. After 7 days of natural carbonation, the leaching concentration of Ba and Pb was below the legal limit in France. The concentration of Ba and Pb in carbonated samples decreased by 98.5% and 98%, respectively. Analyses using thermogravimetry, X-ray diffraction, scanning electron microscopy, and energy-dispersive spectroscopy demonstrated the increased formation and quantity of calcite (CaCO<sub>3</sub>) with longer carbonation times, along with the formation of new minerals as BaCO<sub>3</sub> and PbCO<sub>3</sub>, confirming the immobilization of these elements post-carbonation. The leaching behavior and release potential of carbonated WPFA were further evaluated using the four-stage sequential extraction procedure proposed by the European Commission’s Bureau of Reference (BCR).

This study meticulously scrutinizes the repercussions of COVID-19 on the urban environment, focusing specifically on Dhaka City. In this comprehensive exposition, we explore the multifaceted impact of the COVID-19 outbreak, spanning environmental and non-environmental aspects like urban water quality, air quality, municipal waste management, and noise pollution. We analyze urban environmental data across distinct timeframes, employing the Indicators, Impact, and Strategy (IIS) framework for environmental improvement and urban sustainability. The study reveals substantial shifts in the urban environment, poised to exert a profound influence on the city’s inhabitants and overall urban ecology. Notably, findings indicate a marked improvement in air and water quality, attributed partly to reduced industrial activity and diminished vehicular emissions during lockdowns. However, municipal waste management faced significant challenges, resulting in a deterioration of the overall waste disposal system. Of particular concern was medical waste disposal due to the increased generation during the pandemic. The study concludes by proposing a robust policy framework addressing key concerns, including environmental quality, urban health, and pollution control. These policy recommendations aim to bolster sustainable environmental progress within the unique exigencies of the COVID-19 era. As Bangladesh grapples with the pandemic’s aftermath, this research offers valuable insights and a roadmap for ensuring a more resilient and environmentally sustainable urban future in Dhaka City.</p></div>","PeriodicalId":100598,"journal":{"name":"Green Technologies and Sustainability","volume":"2 2","pages":"Article 100074"},"PeriodicalIF":0.0,"publicationDate":"2024-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949736124000010/pdfft?md5=eee7f8636d976bfeacdea35431bd3f32&pid=1-s2.0-S2949736124000010-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139639338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
