The transition towards sustainable industrial development has necessitated the adoption of circular economy principles, particularly within the context of eco-industrial parks (EIPs). This paper examines the effectiveness, challenges, and implications of harnessing circular economy practices in EIPs and their significance for sustainable industrial development. The study explores the optimization of resource utilization, waste reduction, and collaboration among industries within EIPs. It identifies challenges related to stakeholder collaboration and policy frameworks that hinder the widespread adoption of circularity. The findings emphasize the need for stakeholders to promote collaboration, develop supportive policies, and establish effective resource-sharing mechanisms to enhance the implementation of circular economy principles in EIPs. The research contributes to the existing knowledge by expanding our understanding of circular economy practices within the specific context of EIPs and their contributions to sustainable industrial development. It also provides recommendations for advancing circular economy implementation in EIPs, including strategies for EIP developers and managers, policy recommendations for government bodies, and areas for further research and collaboration. By harnessing circular economy principles in EIPs, stakeholders can create more sustainable and resilient industrial systems aligned with the objectives of sustainable development.

The study examined the impact of trade openness on economic development in Nigeria for the period of 1981-2018. Time series data and econometric techniques like ADF Unit Root Test, Cointegration and ARDL model were used. It was found that there is a long run and positive relationship between Trade Openness and economic growth in Nigeria. The study concluded that trade openness is an important determinant of economic growth. The study therefore recommends that government provide sound trade policies that guarantee and enhance, trade openness for national and international economic integration and boost economic development.

On the road to carbon neutrality, the installation capacity of renewable energy technologies is increasing daily. Due to its inherently intermittent power generation profile, integrating battery energy storage systems (BESS) is critical to ensure a sustainable and reliable energy supply. In a competitive market, high-performance battery technologies developed by many manufacturers will drive the trend toward hybrid power systems (HPS). This paper proposes optimum HPSs with minimum cost for prosumers in the distribution grid using shared BESS, considering battery technologies. Also, the feasibility outputs are compared technically, economically, and environmentally in multi-year sensitivity analyses. Moreover, the impact of daily and hourly simultaneous demand variations is evaluated in aging characteristics for different battery technologies. In addition, the scope of the analysis is deepened by the effects of a high carbon tax on feasibility outcomes in zero carbon tax policies. The results confirm the superiority of NaS battery technology in terms of its financial and renewable potential and LAB benefits for carbon emissions and BESS technical performance. In the later stages, hybrid demand variability further impacts the LAB technology, reducing cycle degradation by up to 7.43% and increasing throughput by up to 11.26%. Additionally, a high carbon tax could reduce CO2 by up to 9.4% and increase the renewable rate by up to 5.2%. Assessing the feasibility trade-offs in BESS technology selection from multiple perspectives will provide credible win-win environments for stakeholders.
