In this study, we critically examine the potential of recycled construction materials, focusing on how these materials can significantly reduce greenhouse gas (GHG) emissions and energy usage in the construction sector. By adopting an integrated approach that combines Life Cycle Assessment (LCA) and Material Flow Analysis (MFA) within the circular economy framework, we thoroughly examine the lifecycle environmental performance of these materials. Our findings reveal a promising future where incorporating recycled materials in construction can significantly lower GHG emissions and conserve energy. This underscores their crucial role in advancing sustainable construction practices. Moreover, our study emphasizes the need for robust regulatory frameworks and technological innovations to enhance the adoption of environmentally responsible practices. We encourage policymakers, industry stakeholders, and the academic community to collaborate and promote the adoption of a circular economy strategy in the building sector. Our research contributes to the ongoing discussion on sustainable construction, offering evidence-based insights that can inform future policies and initiatives to improve environmental stewardship in the construction industry. This study aligns with the European Union’s objectives of achieving climate-neutral cities by 2030 and the United Nations’ Sustainable Development Goals outlined for completion by 2030. Overall, this paper contributes to the ongoing dialogue on sustainable construction, providing a fact-driven basis for future policy and initiatives to enhance environmental stewardship in the industry.

“…The most recent academic research is expanding the scope of investigation toward consumers' attitudes and behavior. Therein, the focus lies on incentives to increase the recycling rate (Roca i Puigvert et al, 2020;Wankmüller et al, 2023), consumer attitudes toward and usage of deposit refund systems (Oke et al, 2020), and the importance of fact-based information for creating consumer awareness and supporting a more sustainable buying behavior (Boesen et al, 2019;Otto et al, 2021). Steenis et al (2017) show that consumers use misleading, inaccurate beliefs to judge packaging sustainability and are therefore susceptible to making ineffective environmental decisions.…”

Returnable packaging systems (RPS) related to consumer products help to reduce problematic plastic and glass waste in supply chains. The purpose of this paper is to investigate distribution and return processes and the related cost drivers and benefits of returnable packaging with a deposit refund system in retail stores. Through the lens of the actor–network theory and based on 30 interviews with store managers, including on‐site observations, we develop a research model that structures key processes of RPS and their input and output factors. By subsequently applying system dynamics modeling, we find that: (1) customers’ process satisfaction, (2) price elasticity of demand, and (3) time between repeat purchases are key variables that impact RPS’ attractiveness and performance. This research contributes to an in‐depth understanding of processes within RPS as well as interdependencies between cost drivers and benefits for retailers. From a managerial perspective, these insights can enable retailers to take action based on the influencing factors for efficient operations related to RPS. Finally, this research has policy implications as it provides argumentation for the commercial benefits of RPS for retailers aside from the overemphasized cost perspectives.

“…The decentralized nature of blockchain ensures that data is distributed across a network of nodes, mitigating the risks posed by a single point of failure and enhancing the overall resilience of the IMS against security threats [22]. Moreover, the immutability and consensus mechanisms intrinsic to blockchain contribute to data integrity, providing a robust foundation for real-time and transparent inventory management processes [23]. As the potential of blockchain technology is harnessed, it opens avenues for redefining the standards of security, efficiency, and transparency in inventory management systems [24].…”

In contemporary business organizations, the pivotal role of automation in control processes is evident through Inventory Management Systems (IMS), which leverage advanced techniques and data analytics algorithms to optimize inventory levels, enhance accuracy, and minimize costs. However, existing security techniques for Inventory Management Systems (IMS), including access controls, firewalls, and audits, face challenges in effectively addressing the evolving threat landscape. These limitations, including struggles with dynamic user roles, susceptibility to data manipulation, and challenges in thwarting various cyber threats, necessitate innovative solutions for robust real-time management and security. Consequently, this work proposes a novel hybrid approach that integrates blockchain with RFID data, Generative Adversarial Networks, and Elliptic Curve Diffie-Hellman cryptographic techniques. In the developed hybrid approach, RFID readers are leveraged to collect inventory data, while the Generative Adversarial Network is specifically designed for processing the raw dataset, encompasses data filtering, normalization, and error correction tasks. The utilization of the Elliptic Curve Diffie-Hellman technique is integral for generating both private and shared keys, facilitating secure transmission between the IMS client and cloud-based servers. The blockchain module is engineered to enhance data security and protect shared secret keys, which is achieved through a two-layer mechanism involving encryption via the Advanced Encryption Standard algorithm and SHA-256 hashing function. Additionally, it incorporates the Artificial Algae Algorithm and an Elman Neural Network to ensure robust data access and integrity. To assess the effectiveness of the proposed hybrid approach, it is implemented on a publicly available dataset. The performance assessment involves a comprehensive comparison with state-of-the-art security methods, considering key metrics such as encryption time, decryption time, key generation time, throughput, latency, and data confidentiality rate. Simulation results conclusively demonstrate that the proposed hybrid approach significantly reduces encryption time, decryption time, key generation time, and latency. Furthermore, it notably improves throughput and data confidentiality rates while aligning with stringent IMS security requirements.
