• Is It Possible to Produce Polyhydroxyalkanoate (PHA) Bioplastics of Consistent Composition from Organic Wastes? A Review
  11 October 2024

  Abstract

  The main aim of this paper is to address the available literature on the issue of controlling the composition of polyhydroxyalkanoates (PHAs) during their production from organic wastes and if possible, provide a complete strategy to achieve consistent composition. Improvement in the handling of single-use packaging can result in tangible results in the quality of everyday life and the reduction of pollution. PHA bioplastics are candidate materials for many applications in the packaging sector. The cost of production of PHA bioplastics can be reduced with the use of organic waste streams as feedstocks. However, variations in the composition of the feedstock, result in variations in the composition of the final product. Feasibility of organic wastes utilization to produce PHA bioplastic depends on the ability to produce a consistent product-material. In this study, we focus on methods developed and tested to produce consistent composition and properties of PHA bioplastics from organic wastes. Numerous studies show that composition control can be established without affecting the global productivity and yield. The critical stages for composition control are the stages of feedstock selection, feedstock storage, and acidogenic fermentation. Fine tuning of the PHA composition is possible by mixing or synthetic feed in the stages of accumulation and extraction. Strategies for minimizing synthetic feed are suggested for process viability. Though various studies have shown that it is possible to obtain a consistent PHA material from organic wastes, strategies need to be developed to achieve consistency without affecting productivity and yield.

• Circular Economy: A Catalyst for Economic Growth - An Empirical Study
  10 October 2024

  Abstract

  Background Problem

  The concept of a “Circular Economy (CE)” emerges as an effort to deal with sustainability problems like diminished resource availability, degradation of biodiversity, and climate variability by means of purposeful redesign of procedures and goods, recycling of materials, and the utilization of sources of clean energy over all energy in the manufacturing process.

  Objectives

  CE Procedures also support and rebuild the ecosystem, human health, and a healthy society, while resources are utilized to produce value so that economic growth is not obstructed by a lack of supplies of raw materials. Additionally, CE also acts as a tool for achieving an extensive list of SDG objectives. SDG 8 is concerned with adequate work and growth in the economy, while SDG 7 is about clean and inexpensive energy.

  Brief Methodology

  The research presented here employs a regression technique for examining the influence of the principles of the circular economy on growth in the economy, thereby helping toward accomplishing the United Nations Sustainable Development Goals (SDGs).

  Brief Results

  The outcomes demonstrate a slight but substantial effect, and that has been confirmed by an ANOVA test that disapproves of the null hypothesis. The coefficient analysis demonstrates a beneficial connection within circular economy methods, lowering waste production as well as economic output.

  Overall Significance of Undertaking the work

  This evaluation additionally emphasizes the circular economy’s essential role in promoting economic acceleration while positively influencing UNSDGS achievement, affirming its position as an important driver of a developing and sustainable economy in accordance with developing worldwide objectives.

• Macroeconomic Influences on Recycling in Europe: An Econometric Investigation
  10 October 2024

  Abstract

  While the circular economy has garnered significant attention over the last two decades, few studies have explored the relationship between recycling and macroeconomic conditions. This paper aims to elucidate how macroeconomic factors influence and correlate with recycling indicators, focusing on European waste management. First, we analyze how macroeconomic indicators impact key circular economy indicators related to waste management, considering 27 European countries from 2000 to 2019, categorized into Western, Southern, and Eastern Europe. An ordinary least squares model serves as a baseline for comparison with a fixed effects model and a model with regional and time dummies. As a response to Ferrante and Germani's (2020) call for more research on causal studies of this kind, we also address reverse causality both by testing for panel data Granger causality and by applying the dynamic panel data approach developed by Arellano and Bond (1991). Second, we investigate variations in circular economic performance across European regions and countries, both before and after controlling for the macroeconomic context. The empirical analysis reveals a substantial correlation between circular economy indicators and key macroeconomic conditions, but we do not find evidence supporting causal impacts from macroeconomic circumstances in the short run. Regional examinations unveil disparities in circular economic performance, with Western Europe generally surpassing Southern and Eastern Europe. However, these patterns align more closely when considering the macroeconomic context. The methodologies employed in the study may prove valuable for future research on the circular economy and its relation to macroeconomic influences.

It focuses on the necessity of adaptable approaches to foster resilience and innovative strategies in the sector. It questions how could Palestinian higher education learning programs integrate and adopt circular economy principles in the context of uncertainty and crises.

  Methodology

  We explore the literature review to examine the transferable models to the situation. The local studies about Palestinian institutions’ governance and the digital transition to achieve a circular economy will be surveyed to design a model taking into account the challenges of the required balance between sustainable development and the sempiternal crisis.

  Findings

  Raising awareness, coping with crises, and recruiting resources appeared in the literature review as critical factors to engage more in a circular economy.

  Limitations

  There is limited access to papers from the Palestinian context linking the circular economy with sustainable development in higher education institutions.

  Practical Implications

  We learned from this meta-cognitive analysis that people living in permanent crisis and war areas need resilience and perseverance to cope with crises, achieve sustainable development education goals, and maintain quality.

  Value

  The main contribution of this reflection consists of triggering awareness among the Palestinian higher education community of the crucial role of circular economy principles in maintaining the permanent reconstruction of individuals and their living spaces. Innovation and entrepreneurship constitute the two pillars of an education system adapted to the needs of students evolving in the context of permanent crises.

• Enablers and Barriers of Circular Economy in Manufacturing Context for Indian Industries
  09 October 2024

  Abstract

  The production industry is the backbone of the contemporary economy. By examining the scholarly literature, this research aims to reexamine the idea of a production-centered circular economy system. Its goal is to determine if the difficulties around this idea have changed through time and whether applicable examples have appeared. The main goal is to examine the major barriers and enablers that promote or prevent the adoption of a circular economy in the context of Indian manufacturing. In our investigation, we found 22 enablers and 37 barriers to the circular economy in Indian industry. These conclusions were reached by examining how often certain events occurred in study publications. The identified barriers and enablers have all been grouped into six groupings as a result. A survey questionnaire was created and sent to respondents, who included managers, owners, engineers, and supervisors in the Indian manufacturing industry, in order to verify these barriers and enablers. To guarantee a high response rate, these surveys were sent out through email and delivered personally to businesses in the area. The main goal was to direct responders towards making clear-cut selections that were informed. The information gathered came from individuals with a range of manufacturing industry experience, from one year to a maximum of forty years. Notably, a sizable share of India's industrial sector is made up of small and medium-sized businesses.

  Abstract

  The need to research crucial barriers and drivers that could impede the adoption of novel sustainable farming technique has increased. The study aims to explore the evolution and application of the circular economy (CE) principles within the agribusiness sector, highlighting how these practices have developed over time to enhance sustainability and efficiency. To provide a clear understanding, a visual timeline is included to illustrate key milestones and trends in the adoption of CE in agribusiness. For this reason, this research presents a literature-based synopsis of the primary challenges and opportunities that agribusinesses face in securing their future prosperity. A systematic literature review (SLR) of 164 articles was conducted for this study. Articles are identified and analysed using content analysis for this study. Barriers and drivers to the development of sustainable agribusinesses are highlighted in the conceptual framework. According to the SLR's findings, the biggest obstacles to the long-term success of agribusinesses are insufficient financial backing, excessive post-harvest loss, gender inequality, financial, technological, and non-climate-smart policies, and weak institutional controls. The scope of this research is restricted to challenges, opportunities, and practices related to agribusiness sustainability and does not include the broader notion of agriculture. Two primary aspects set apart this study. In the first place, it offers a practical checklist for fixing issues that threaten the longevity of agribusinesses. Secondly, future research can be aided by this study's findings and the research gaps it identifies.

• Prioritizing Performance Indicators for the Circular Economy Transition in Healthcare Supply Chains
  09 October 2024

  Abstract

  The emergence of the circular economy (CE) paradigm is a key driver in steering industrial sectors towards sustainability. The formulation of a robust circularity strategy depends on a comprehensive assessment, which is closely related to the overarching goal of managing the transition to circularity. The initial phase of transition within the healthcare sector reinforces the need to seamlessly integrate CE principles. It is therefore imperative to define and carefully monitor indicators that will help assess and improve sustainability, operational efficiency, supply chain resilience and stakeholder satisfaction, including both consumers and patients. The primary objective of this research is to prioritize relevant performance indicators that will be critical in measuring the effectiveness of the transition to a circular economy within the healthcare supply chain. To achieve this objective, the study employs the Analytic Hierarchy Process (AHP), a well-established methodology known for its effectiveness in solving complex multi-criteria challenges. The AHP is used to prioritize performance indicators that facilitate the management of the circular economy transition in the healthcare supply chain. The focus is on improving the quality of care, optimizing delivery efficiency, and emphasizing environmental sustainability within the healthcare paradigm. The methodological framework includes the identification of key main criteria covering environmental, social, economic, and logistical dimensions. These criteria are further refined with the inclusion of 14 sub-criteria, resulting in a list of 16 key performance indicators (KPIs). Additionally, the study proposes an alternative business model advocating for the implementation of the Circular Supply Chain Operation Reference Model (circular SCOR). This model offers a perspective for rapid change in supply chain processes towards circular transition within the healthcare system. The final stage of the research involves verifying the results through sensitivity analysis and correlation mapping of the indicator results with the Circular SCOR model. This process helps organizations refine their performance measurement protocols, enhancing their capacity for effective evaluation and strategic decision-making within the circular economy framework. This comprehensive approach enables healthcare organizations to proactively contribute to a more sustainable and environmentally conscious future while maintaining a focus on quality care for patient well-being.

• Understanding the Level of Integration in Existing Chemical Clusters: Case Study in the Port of Rotterdam
  09 October 2024

  Abstract

  The petrochemical industry is composed of several interconnected processes that use fossil-based feedstock for producing chemicals. These processes are typically geographically clustered and often belong to different parties. Reducing the environmental impacts of the petrochemical industry is not straightforward due to, on the one hand, their reliance on fossil fuels for energy and as a feedstock and, on the other hand, the significant level of interconnected energy and material flows among processes. Current methods for analyzing changes to existing processes cannot capture the multitude and level of interactions. The goal of this paper is to create a model of a petrochemical cluster and analyze its physical characteristics and performance. This paper addresses this goal by developing an assessment method that combines process simulations, multiplex graph analysis, and key performance indicators. The method is applied to a case study based on the petrochemical cluster in the Port of Rotterdam, resulting in a uniquely highly detailed model of a petrochemical cluster. The network analysis results show that only some of the processes are very interconnected. From the performance analysis, it can be observed that the olefins process is the most carbon-intense and has high CO₂ emissions. Additionally, the results showed the importance of considering existing interconnections when assessing the current performance of existing petrochemical clusters or the performance due to future changes to chemical processes. For instance, some changes would occur to an industrial cluster by introducing alternative carbon sources, such as biomass or CO₂.
