Senior Research Fellow in SME Industrial Systems
Dr. Marcus Thorne leads empirical fieldwork at CISR, examining resource asymmetries and reverse supply chain bottlenecks in Northern European manufacturing firms. Prior to joining CISR, he completed postdoctoral research on industrial ecology and enterprise operations.
While circular economic paradigms have been broadly studied within multinational corporations, small- and medium-sized enterprises (SMEs) face distinct resource asymmetries, structural rigidities, and capital constraints when operationalizing circularity. This study investigates the institutional conditions, organizational capabilities, and technology integration mechanisms required for manufacturing SMEs to transition successfully toward closed-loop industrial ecosystems. Employing an empirical mixed-methods design, we examine survey data from 142 enterprise owners and executive directors across Sweden, Denmark, and Finland, triangulated with 18 in-depth qualitative field audits of advanced manufacturing facilities conducted between 2023 and 2025. Our findings reveal that while 68% of surveyed firms maintain strategic intent toward product remanufacturing and material recovery, fewer than 22% have embedded circular performance metrics into their capital expenditure authorizations or supplier appraisal frameworks. We identify cross-tier reverse supply chain transparency, digital product passport infrastructure, and collaborative multi-stakeholder municipal hubs as paramount determinants for commercial viability. Conversely, regulatory friction in waste taxonomy classification persists as the primary institutional impediment across Nordic jurisdictions. We conclude by presenting an actionable 4-phase circular transition archetype for enterprise management alongside 3 policy directives for European industrial decarbonization frameworks.
We examine secondary market transactions of 3,400 corporate debt securities issued across European exchanges between 2020 and 2025. Applying propensity score matching and firm-level fixed effects, we isolate a statistically significant green premium of 4.2 basis points for investment-grade issuers with verified third-party taxonomy alignment. However, this premium dissipates entirely among issuers exhibiting substantial ESG rating divergence across major rating providers, suggesting investor skepticism toward ambiguous sustainability disclosures.
The European Union’s Ecodesign for Sustainable Products Regulation (ESPR) establishes Digital Product Passports (DPPs) as mandatory compliance mechanisms. This research report details architectural frameworks for decentralized material tracking, analyzes data governance models, and documents implementation costs across 45 mid-market European suppliers in industrial machinery and textiles.
