highlight the most pressing environmental challenges addressed in the literature,
demonstrating how Blockchain, Artificial Intelligence (AI), Big Data Analytics (BDA), and
the Internet of Things (IoT) contribute to reshaping corporate sustainability strategies.
The circular economy is one of the most extensively explored impact areas, emphasizing
how digital technologies facilitate waste minimization, sustainable production cycles, and
material reutilization. Blockchain plays a crucial role in ensuring supply chain transparency,
allowing companies to track material flows, optimize recycling processes, and prevent
greenwashing (Singh et al., 2024). By integrating smart contracts, businesses can enforce
waste reduction policies, ensuring compliance with circular economy principles across
supply chains (Calandra et al., 2023; Jan et al., 2024). Blockchain-based smart contracts
trigger automated actions, such as payments or reporting, once predefined conditions are
met. In circular economy applications, these self-executing digital agreements can, for
instance, enforce compliance with take-back schemes or ensure payment upon verified
delivery of recycled materials. Additionally, blockchain enables the creation of digital
product passports that record the material composition, origin, and lifecycle status of
products, facilitating reuse, recycling, and remanufacturing.
AI-driven predictive analytics further support circular economy initiatives by optimizing
material classification, improving waste sorting automation, and refining recyclability
assessments (Ali et al., 2024; Tutore et al., 2024). These AI systems leverage machine
learning algorithms to detect patterns in waste streams, enabling the classification of
materials with high precision. This enhances the efficiency of recycling facilities by reducing
contamination rates and ensuring that materials are directed to the appropriate recovery
channels. Furthermore, AI models can simulate product life cycles to suggest design
improvements that increase recyclability. These AI models are often trained and refined
using large datasets provided by Big Data platforms, which aggregate information from
production processes, supply chain audits, and end-of-life treatment data, highlighting a
strong interdependence between AI and BDA in circular economy applications.
IoT-enabled waste tracking systems provide real-time insights into material flows, allowing
firms to prevent overproduction, optimize inventory management, and reduce landfill
contributions (Cui et al., 2024; Zhu et al., 2024). IoT sensors installed throughout the
production and distribution chain collect data on material usage, waste generation, and
disposal timelines. These sensors feed data into centralized systems that enable dynamic
