Every year, tens of millions of the 1.4 billion cars on the world’s roads are decommissioned. While the ferrous and other metals that constitute about 75% of a vehicle by weight can be readily and profitably recycled, the remaining mix of plastics, glass, composites, complex materials, fragments and contaminants are mainly destined for landfill as automotive shredder residue (ASR). For every car, approximately 100–200 kg of ASR is disposed of in landfill, posing a growing technical and environmental challenge worldwide. The recovery of the ASR for high-end application is the focus of this study, aiming to optimise the use of these valuable resources and minimise the extractive pressure for raw materials, a future green manufacturing, contributing towards a zero waste circular economy. As the dissolution of carbon into iron is a key step in the manufacture of iron-carbon alloys, the feasibility of utilizing the waste polymers within ASR as sources of carbon in different areas of pyrometallurgical processing was investigated. Polypropylene and rubber, in a blend with metallurgical coke, were used as carbonaceous substrates and the slag-foaming phenomenon was investigated via the sessile drop technique in an argon environment at 1,550°C. The results indicated the rubber/coke blend achieved significantly better foaming behaviour, and the PP/coke blend exhibited a moderate improvement in slag foaming, in comparison to 100% metallurgical coke. The overall results indicated the incorporation of ASR had significant improvement in foaminess behaviour, increasing furnace efficiency.

This paper discusses the role of Albert O. Hirschman as a founder of development economics in the postwar years. Although Hirschman maintained a strong interest in development matters throughout his entire professional career, his major contributions to development economics took place between the mid-1950s and the late 1960s. The paper examines Hirschman’s innovative contributions to the new discipline. When, in the 1950s, development economics gravitated around the concept of “balanced growth,” Hirschman opened new vistas with a theory of “unbalanced growth.” In the early 1960s, Hirschman focused on reformist political approaches to development, against the opposed extremisms of reaction and revolution. Finally, in the late 1960s, Hirschman opened new perspectives on the importance of detailed analysis of development projects, against the theoretical drift of early development economics.

The discussion of Hirschman’s development career is also an opportunity to observe the gap between theoretical debates and development policies. Whereas development economists often clashed on theoretical issues, their views were remarkably closer on practical questions.

As a pioneer of development economics, Hirschman sought to establish it as a discipline theoretically distinct from mainstream economics. By the 1980s, this project had collapsed, and the development question was reabsorbed by the economic mainstream. This article, however, argues that current development debates remain deeply indebted to Hirschman’s contribution. His reformist vision, rejection of one-size-fits-all solutions, his insistence on the ineluctable role of uncertainty, and his search for country-specific, incremental, and evolutionary policies make his approach central to current development discourse.
