A Systematic Review of the Implementation, Benefits, and Challenges of the Energy Management System Based on ISO 50001 | Chapter 8 Science and Technology: Recent Updates and Future Prospects Vol. 10

 

A serious challenge in facing climate change is how to significantly reduce CO2 emissions from industrial activities. On the other hand, there is an increase in demand for energy consumption which has been followed by significant support efforts to encourage sustainable supply by exploring new low-emission resources, developing technology and conservation, and implementing energy mix strategies. In line with this, the development and implementation of a management system in energy utilization plays an important role. Based on several studies, the implementation of ISO 50001 has a significant influence on improving energy management performance, energy cost savings, and reducing CO2 emissions. This paper will review the current state of the implementation of this standard, its benefits, and challenges based on literature studies from several scientific journals and publications released by international organizations, associations, and government policies. The cost of implementation of this standard varies depending on the business model, sector, and period of implementation. Besides that, implementation of this standard also has a positive influence on the management of energy assets, evaluating and prioritizing the use of energy-efficient technologies, and driving efficiency throughout the supply chain. Several selected case studies that describe quantitative energy performance affected by the implementation of ISO 50001 at the international level with various sectors and several role models from Indonesia are explained. In general, it can be concluded that the implementation of ISO 5001 contributes significantly to increasing energy efficiency and reducing CO2 emissions. In addition, the challenges and difficulties faced by the implementation of this standard are also reviewed.

Evaluating the Performance of Portland Limestone Cement in Concrete Pavement and Bridge Decks: Current Insights and Future Directions | Chapter 6 | Engineering Research: Perspectives on Recent Advances Vol. 7

 

Over the years, the construction industry has heavily depended on the use of ordinary Portland cement (OPC) in diverse kinds of construction. With the rising demand for sustainable infrastructure, addressing the limitations of OPC is crucial, particularly for exposed structures such as pavements and bridge decks. Portland limestone cement (PLC) is a sustainable alternative that delivers environmental benefits and comparable performance. Previous review studies have primarily concentrated on laboratory-based assessment of PLC, providing limited insights into real-world applications. This study used a systematic review and meta-analysis with a random-effects model to evaluate PLC’s strength development, durability, and sustainability. The meta-analysis was conducted using a random-effects model. The findings indicate that PLC generally matches or surpasses OPC in terms of compressive strength, freeze–thaw resistance, and sulfate durability. However, its setting time and early-age cracking require further optimisation, especially in cold climates. Additionally, this study highlights the fire performance advantages of PLC and its enhanced chloride resistance. The most significant advantage of PLC lies in its sustainability. The reduced clinker content significantly lowers the carbon footprint associated with cement production; this is a critical factor in global efforts to mitigate climate change. The analysis identified critical research gaps, including long-term field performance and regional adaptation to extreme environmental conditions. These findings contribute to a deeper understanding of PLC’s role in sustainable construction and offer future research directions on hybrid cements and admixture compatibility. The recommended future research direction can ensure PLC becomes a key material in the global push for greener construction practices.

Visible Light-activated 2-Phenyl Indole (PI)/TiCl4 Complexes for Atmospheric CO2 Capture and C6-C17 Organic Synthesis via Hydroxyl Radical Synergism | Chapter 9 | Chemistry and Biochemistry: Research Progress Vol. 1

Preferred systems are catalysts that operate away from equilibrium, continuously supplied with energy and materials from inexhaustible sources such as sunlight, air, and water. This concept underpins artificial photosynthesis (AP). A novel self-organized chemical "living" system is presented that mimics natural photosynthesis by capturing CO₂ and H₂O from the atmosphere under ambient conditions. Using 2-phenyl indole (PI) and TiCl₄ complexes activated by visible light, this system autonomously reduces CO₂ with H₂O protons to produce long-chain oxygenated hydrocarbons up to C₁₇. The process begins with hydrolyzed PI/TiCl₄ complexes reacting with CO₂ to form organotitanium carbonates, with the 2:1 PI/TiCl₄ ratio proving most effective. Visible light reduces Ti+⁴ to Ti³⁺ and Ti²⁺, generating hydroxyl radicals, which play a critical role in the reduction of CO₂ to CO, H₂CO, and CH₃OH. These intermediate further couple to form C₆ to C₉ α-carboxylic acid-ω-aldehyde compounds, which serve as feedstocks for the subsequent synthesis of longer carbon chains (C₁₂ to C₁₇) through a radical mechanism. The system facilitates ligand exchange between PI and donor molecules, forming adducts involved in the photocatalytic process. Additionally, PI oligomerization contributes to the formation of functional oligomers. Over two dozen intermediates and products were identified using MALDI-TOF, ¹³C NMR, and IR spectroscopy, highlighting the complexity of the reaction network. This catalytic system uniquely integrates organotitanium chemistry and hydroxyl radical pathways, autonomously capturing CO₂ and humidity from the atmosphere while harnessing solar energy to produce valuable long-chain oxygenated hydrocarbons. This prototype offers a foundation for exploring broader applications and enhancements using other metals and ligands.
