TOWARDS A ZERO WASTE URBANISM: A MANIFESTO FOR SUSTAINABLE FUTURES
Full text linkPressing global environmental problems can be solved only by facing the social problems within society and vice versa. These crises can be approached from different perspectives. In 2016, an estimated 2.01 billion tonnes of municipal solid waste were generated and this number is increasing fast. The problem of where and how to dispose of this material is an environmental issue that is in need of a solution. This issue is prevalent in cities, which are the main site of production and consumption, as well as rapid urbanisation. Often urbanism refers to something that deals with buildings, roads, and other design elements. However, urbanism is much more, and, as theorised long ago, explores the intersection of the physical structures, the social organization, and the attitudes and ideas that are found in cities. This article considers the zero waste tradition, looking in particular to zero waste cities, and putting it in dialogue with critical traditions, in particular urban political ecology. Zero Waste Urbanism is introduced as a both a fresh perspective and a call for action, not only to design better cities but to change society and rework political systems. By making its key questions those that interrogate power, zero waste urbanism radicalizes the zero waste approach, developing new ways of exploring reality while proposing a reconstructive vision to create sustainable urban futures. In doing so, this work aims to reach both zero waste practitioners, interdisciplinary researchers, and academic activists

Full text linkWaste: the contribution of Zero Waste and geography to the implementation of the PNRR. – Waste is a central problem of global society, capable of deeply undermining the future of the planet. The consumerist mentality and practices are know for guaranteeing productions capable of responding to a growing demand that is ever more diversified. However, less concern has been given to the so-called final ring of the economic system, the one related to waste management. This lack of attention has ensured that a solution to the issue of waste cannot be longer postponed, but has to be considered the starting point for reconsidering the entire process, investing with energy and foresight on the cultural, even before economic, value of circularity, as an alternative to the short-sighted and no long-er sustainable linear model. And it is precisely within this framework, theoretical and practical at the same time, that the PNRR policies must depart and try to be effective, capable of taking up the challenge proposed by Zero Waste: overturn the metaphor of the pyramid and insert in the broad apex a new design of the entire production and consumption chain, at the corporate and domestic, collective and individual, local and global levels. This desirable renewed direction of thought will benefit from the help of geographical reflection, able to propose, thanks to its gaze capable of keeping together different elements and various plans, important concepts and functional criteria to undertake a definitive change of course, towards an effective sustainability
STUDENTS’ RELATIONSHIP WITH WASTE: THE EXPERIENCE OF THE ZERO WASTE APPROACH IN EDUCATIONAL CONTEXTS [Il rapporto degli studenti con i rifiuti: l’esperienza dell’approccio Rifiuti Zero in contesti educativi.]
No full textLa tematica relativa alla produzione e gestione dei rifiuti è spes-
so trascurata, ma i dati preoccupanti ne evidenziano l’urgenza. L’approccio
Rifiuti Zero, sviluppato con l’obiettivo di evitare la produzione di rifiuti e
ripensare i modi di produzione e consumo, emerge come soluzione crucia-
le. Questo studio presenta una ricerca-azione nel Friuli Venezia Giulia,
focalizzata sulla sensibilizzazione e diffusione dell’approccio Rifiuti Zero
in alcune località turistiche della regione. Coinvolgendo all’incirca 600 stu-
denti di scuole secondarie di primo grado e scuole professionali, i risultati
iniziali indicano una comprensione generale della gestione dei rifiuti e un
interesse nei confronti dei principi di Rifiuti Zero, mostrando la volontà
degli studenti di agire per un futuro sostenibile
VERSO UN FUTURO RIFIUTI ZERO: DINAMICHE DI GESTIONE E PREVENZIONE DEI RIFIUTI NELLE DESTINAZIONI TURISTICHE DEL FRIULI VENEZIA GIULIA
Full text linkQuesto studio nasce all'interno di un progetto di ricerca-azione partecipata incentrato sulle destinazioni turistiche del Friuli Venezia Giulia. Esamina le pratiche e le strategie attualmente adottate o da adottare per migliorare la gestione dei rifiuti e promuovere comportamenti virtuosi e azioni preventive. Sono stati sviluppati percorsi condivisi di co-creazione di conoscenza con i politici, le aziende di gestione dei rifiuti e i principali stakeholder del settore turistico di ogni comune coinvolto,
che hanno portato a una comprensione più approfondita delle problematiche legate alla raccolta e alla gestione dei rifiuti e,
di conseguenza, alla formulazione di iniziative mirate alla loro, seppur parziale, risoluzione.
Questo lavoro analizza le sfide comuni relative alla gestione dei rifiuti affrontate dalle destinazioni turistiche e propone misure per diffondere una visione di Rifiuti Zero
R&D and productivity in high-tech manufacturing: a comparison between Italy and Spain
Full text linkUsing data for twelve manufacturing industries over the period 1980-2006, we perform for Italy and Spain a dynamic panel estimation of the long-run elasticity of TFP with respect to R&D capital. The results show that in Spain high-tech industries have experienced a similar or slightly higher R&D elasticity than their Italian counterparts. This is mainly attributable to what occurred from the mid 1990s onwards when, thanks to increasing R&D efforts, the Spanish industries have been able to catch up with the respect to the Italian ones. The policy implications of the above findings are discussed
The determinants of AI innovation across European firms
No full textUsing patent data for a panel sample of European companies between 1995 and 2016 we explore whether the inventive success in Artificial Intelligence (AI) is related to earlier firms’ innovation in the area of Information and Communication Technology (ICT), and identify which company characteristics and external factors shape this performance. We show that AI innovation presents strong dynamic returns (learning effects) and benefits from complementaries with knowledge earlier developed in the area of network and communication technologies, high-speed computing and data analysis, and more recently cognition and imaging. AI patent productivity increases with the scale of firm innovation, and is lower for companies with narrow technological competences. There is evidence of knowledge spillovers from ICT innovators to AI innovators, but this effect is confined to the frontier firms of the new technological field. Our findings suggest that, with the take-off of the new technology, the technological lead of top AI innovators has increased due to the accumulation of internal competences and the expanding knowledge base. These trends help explain the concentration process of the world’s data market
