AbstractThe study briefly recalls the evolution and crisis of the theory and thought of John Maynard Keynes with the rise and progressive dominance of the neoliberalism paradigm. The exercise has been made for evaluating the effects of such process for the sustainability of the global economy and society. In this view, we explored how Keynes’ contribution could be useful for the global economy in building a new paradigm of socio-economic development underpinning the transition to circular economy (CE). We also evaluated the adoption of the Global Green New Deal including a case study of Italy for the purpose of suggesting how that topical political programme can be key in the CE transition. Given the urgency of environmental problems, we underline the importance of the adoption of Keynesian expansionary “green mission oriented” fiscal policies with the purpose of allowing the triggering of a virtuous circle of sustainable welfare involving the Green New deal and the transition to CE. At the basis of such virtuous circle, we propose a new paradigm based on a revisited Keynesian paradigm and models of economy within the framework of Genovesi’s “civil economy” that entails an active role and responsibility of all the societal actors (consumers, companies and institutions). In this view, the “spirit” of Keynes in the economy, policy and society could be appreciated once more and be extremely useful along with other scholars’ contributions in accelerating the CE transition and a more sustainable development.

Material Conditions

All powered vehicles have a braking system adopted according to the type of vehicle and work for which they are designed. In Ecuador, there is a great variety of auto parts that are proposed as alternative replacement, varying in cost and quality. This research aims to quantitatively analyze the characteristics of the brake disc material between original and alternate auto parts. This research analyzes three brake disc samples (A, B, C) from different manufacturing sources, using the ASTM E415-08 spectrometry test and the metallography test under the ASTM A247-16A standard. The spectrometry detects 15 elements in each sample, the carbon equivalent of sample A is 18% and 20% higher in relation to sample B and C, which significantly influences the microstructure. The metallographic tests indicate a pearlitic matrix in each sample, however, there is a different distribution and size of the graphite flakes. According to the SAE J431 standard, each auto part meets the material conditions for the brake disc function.
