- Establishing a regional industry 4.0 electronics hub: The GreenUpPCB modelPublication . Dionísio, Rogério Pais; Ünal, Irem; Delgado-Prieto, M.; Romeral Martinez, L.This chapter presents GreenUpPCB as a regional Industry 4.0 hub for electronics repair and retrofitting, based in Castelo Branco, Portugal. The initiative combines artificial intelligence, machine vision, 3D printing, and automation to extend the life cycle of obsolete printed circuit boards, particularly in renewable energy systems and railway rolling stock. By promoting circular economy practices and reducing electronic waste, GreenUpPCB supports sustainable and resilient industrial operations. The hub also strengthens regional development by linking academic research with industrial needs, offering training, innovation, and high-tech services to local small- and medium-sized enterprises. Its model enables smart manufacturing adoption in low-density territories without dependence on urban clusters. Aligned with the European Chips Act and national strategies for microelectronics, GreenUpPCB demonstrates how regional hubs can contribute to the green and digital transitions across multiple sectors, including energy and transport.
- Fatigue analysis of sustainable bituminous pavements with artificial and recycled aggregatesPublication . Teijón-López-Zuazo, Evelio; Vega-Zamanillo, Ángel; Santos, C.C.; Gómez-Carrascal, DavidThe circular economy represents a significant opportunity to enhance the mechanical properties of bituminous mixtures, thereby contributing to sustainable development. This research compares the behaviour of traditional bituminous mixtures with sustainable ones that reuse recycled materials, industrial waste products, or additives that improve mechanical or rheological properties. The methodology employed comprised the acquisition of fatigue resistance laws from 4-point bending tests on prismatic specimens. This facilitated the analytical determination of the number of axles of 13 tons that the section of pavement with sustainable material can support for comparison with the axles supported in the conventional mix. The findings corroborate the utilization of sustainable bituminous mixtures in pavement sections, employing the maximum circularity criterion. The fatigue laws calculated must permit the use of different calculation methods or other applications in green infrastructures, such as cycling lanes or pedestrian areas. On sections with an AADT of between 800 and 25 HV/day, all of the analyzed bituminous mixtures with sustainable materials prolong the service life of the road. There were increases in service life of between 25.5% and 6.6%, respectively, which satisfactorily achieved an increase in pavement service life based on the criterion of maximum circularity.
