Landfill bioreactors
No full textIn landfill, the control of degradable organics and related environmental impacts may be achieved by means of a series of options, including avoidance of putrescible fraction in landfilled waste (separate collection), prestabilization of waste prior to landfilling, in situ treatment to enhance biodegradation during landfilling and/or the aftercare phase, combinations, etc. Landfills that are purpose-designed and operated for the in situ treatment of degradable waste with the aim of enhancing conversion processes are known as landfill bioreactors. Possible in situ measures include leachate recirculation, introduction of water, natural or forced aeration, pH control, etc. Improved control of biochemical kinetics, moisture content, and redox conditions may result in a significant shortening of the aftercare phase and consequently, environmentally sustainable targets may be reached in a shorter time. According to biodegradation conditions, landfill bioreactors can be subdivided into four m..
Integrated MSW management in the Asti district (Piedmont): application of LCA to energetic and environmental issues
No full textParticipatory approach, acceptability and transparency of waste management LCAs: case studies of Torino and Cuneo
No full textThe paper summarises the main results obtained from two extensive applications of Life Cycle Assessment (LCA) to the integrated municipal solid waste management systems of Torino and Cuneo Districts in northern Italy. Scenarios with substantial differences in terms of amount of waste, percentage of separate collection and options for the disposal of residual waste are used to discuss the credibility and acceptability of the LCA results, which are adversely affected by the large influence of methodological assumptions and the local socio-economic constraints. The use of site-specific data on full scale waste treatment facilities and the adoption of a participatory approach for the definition of the most sensible LCA assumptions are used to assist local public administrators and stakeholders showing them that LCA can be operational to waste management at local scal
Greenopoli: an innovative approach to environmental education and sustainable behavior
No full textThe Greenopoli method represents an innovative and engaging approach to environmental education, integrating communication, participatory methodologies, and creative teaching tools such as
storytelling and rap music. This paper explores how Greenopoli fosters behavioral change and awareness about sustainability, waste management, and circular economy. By analyzing various educational projects, communication campaigns, and participatory approaches implemented through Greenopoli, we highlight its impact on students, educators, and communities. The case study of Tùttu-cià demonstrates how a multidisciplinary and interactive approach can lead to significant improvements in source segregation, recycling habits, and environmental consciousness (De Feo, 2023). The results suggest that a joyful and inclusive educational framework can enhance the effectiveness of sustainability education
Economia Circolare nelle Università - L'evoluzione del sistema di raccolta differenziata all'Università di Salerno
No full textL’Università degli Studi di Salerno (UNISA) ha intrapreso, dal 2017 al 2024, un percorso di trasformazione radicale del proprio sistema di gestione dei rifiuti verso i principi dell’economia circolare in ambito universitario. Questo articolo analizza in dettaglio tale evoluzione, basandosi sulle ricerche condotte in una serie di tesi di laurea dal 2017 al 2024. Inizialmente, il tasso di raccolta differenziata nel
campus di Fisciano risultava stagnante e inferiore agli obiettivi normativi, evidenziando criticità logistiche e comportamentali. In risposta, l’Ateneo ha sviluppato un Nuovo Piano di Raccolta Differenziata (approvato nel 2018) in collaborazione con l’azienda locale Fisciano Sviluppo S.p.A. e con la Fondazione UNISA, introducendo nuove modalità di raccolta “porta a porta” interne al campus, una migliore integrazione col sistema comunale e un’ampia campagna di sensibilizzazione denominata “UniSAmbiente”. Negli anni successivi sono state implementate iniziative innovative: dall’istituzione di un Waste Manager di Ateneo e campagne di comunicazione rivolte a studenti e personale, fino a progetti
speciali come “CAMBIAMENTI” (coordinato da CONAI) che nel 2024 ha aggiornato la logistica con nuovi colori e contenitori standardizzati e coinvolto attivamente oltre 30 studenti facilitatori ambientali. I risultati hanno mostrato un miglioramento nelle performance di raccolta differenziata e nella consapevolezza
ambientale della comunità universitaria, con l’Ateneo di Salerno oggi allineato alle linee guida nazionali (RUS-CONAI) e pronto a raggiungere ambiziosi obiettivi grazie a un sistema integrato e partecipato di gestione dei rifiuti urbani nel campus
