Nel 2011, 736.644 tonnellate sono state smaltite nella discarica di Jeram Saninary (JSL), mentre nel 2012 sono state smaltite circa 819.840 tonnellate di rifiuti. I rifiuti domestici, i rifiuti ingombranti, i rifiuti da giardino e i fanghi di depurazione domestici sono la classificazione generica dei rifiuti smaltiti a JSL. I problemi di qualità e disponibilità dei dati causano difficoltà ai pianificatori e ai decisori politici nel comprendere le informazioni sulla produzione di rifiuti per formulare strategie di gestione adeguate. L’analisi del flusso di materiali (MFA) è un metodo per quantificare il flusso di materiali a livello di sostanze con dati limitati. Il software Substance Flow Analysis o STAn è stato applicato allo studio del bilancio di massa per il flusso di carbonio (C) e azoto (N) nel JSL. I materiali da biomassa, come carta, scarti di cibo e giardino, legno e tessuti, costituiscono il 62% dei rifiuti solidi urbani. I risultati mostrano che la maggior parte dei rifiuti smaltiti nel JSL è costituita da rifiuti organici, in particolare rifiuti di cucina (32%). La determinazione del flusso di materia per il C e l’N ha mostrato che il 29% del C organico è stato rilasciato nell’atmosfera attraverso il gas di discarica, mentre meno dell’1% è stato rilasciato attraverso il percolato. In uno studio annuale, più del 70% del C organico totale-N (quasi l’80%) era ancora all’interno del corpo della discarica.

    Bret C. Harvey / Steven F. Railsback
    Ecologists now recognize that the dynamics of populations, communities, and ecosystems are strongly affected by adaptive individual behaviors. Yet until now, we have lacked effective and flexible methods for modeling such dynamics. Traditional ecological models become impractical with the inclusion of behavior, and the optimization approaches of behavioral ecology cannot be use...
