Enabling Green Transformation Through IoT and Industry 5.0: A Strategic Roadmap

Abstract

This study develops an Industry 5.0- and IoT-enabled roadmap for green transformation in manufacturing, with a particular focus on Turkish industry. The study combines a structured literature review, bibliometric keyword mapping based on Web of Science records, and interview-informed framework refinement drawing on the sustainability departments of five large-scale manufacturing firms operating in Türkiye. Rather than treating green transformation as a single initiative, the roadmap organizes it into five interrelated modules: emission reduction, clean and reliable energy, circular-economy mobilization, energy- and resource-efficient construction and renovation, and zero-pollution waste management. The main contribution is a five-level qualitative maturity model that shows how firms can move from compliance- and governance-based foundations to integrated, data-driven, and predictive sustainability practices. The framework clarifies which factors are foundational, enabling, or advanced at each level and is intended to be used as a practitioner checklist and strategic assessment tool rather than as a fixed quantitative scoring model. The interview insights were used to refine the sequencing of actions, identify implementation bottlenecks, and adapt the framework to the realities of Turkish manufacturing. By linking human-centric Industry 5.0 principles with operational sustainability priorities, this study offers both conceptual novelty and practical guidance for firms and policymakers seeking to align industrial upgrading with long-term environmental competitiveness.
