Hegel e le scienze sociali
No full textGli studi raccolti in "Hegel e le scienze sociali" propongono una reciproca correzione e integrazione tra la prospettiva filosofica hegeliana e gli snodi cruciali della teoria sociale contemporanea. Le categorie critico-dialettiche, a lungo viste dalla sociologia marxista come il guscio mistico che imprigionava il pensiero e la prassi sociale, acquistano un nuovo significato e finanche una nuova valenza metodologico-euristica.
Teoria del riconoscimento, pensiero critico-dialettico, teoria dello spirito oggettivo rivivono nell’ottica di un confronto dialogico con autori, momenti, crocevia della teorizzazione sociologica, senza quelle pretese di conclusività, integrazione sistemica e conciliazione che potevano aver illuso lo Hegel sistematico.

VALUTAZIONE DEI FLUSSI DI SCARTO NELLA GESTIONE DEI RIFIUTI URBANI IN ITALIA
No full textUna buona raccolta differenziata è la
prima condizione per sostenere una filiera di riciclo
di alta qualità, con il fine ultimo della preservazione
delle risorse naturali e la riduzione degli impatti sull’ambiente.
Per una corretta pianificazione della
gestione dei rifiuti urbani non destinabili a recupero
di materia e una valutazione dei fabbisogni impiantistici,
occorre conoscere non solo la produzione di
rifiuto urbano residuo, ma anche quantificare i flussi
di scarto derivanti dai trattamenti delle raccolte differenziate.
Questi rifiuti devono essere gestiti con
particolare attenzione al contenimento degli impatti
ambientali e quindi preferendo l’incenerimento con
recupero di energia allo smaltimento in discarica, al
quale nel 2018 in Italia si è ancora fatto ricorso per
la gestione del 22% dei rifiuti urbani. La quantificazione
degli scarti generati nelle operazioni di recupero
delle frazioni differenziate è stata l’obiettivo di
questo lavoro. Dall’analisi è emerso che, a fronte di
una produzione nazionale di rifiuti nel 2018 pari a
30,2 milioni di tonnellate e una raccolta differenziata
del 58%, l’attuale gestione e trattamento dei rifiuti
raccolti in modo differenziato generano circa 3,4
milioni di tonnellate di scarti, di cui 3 milioni sono
idonei al recupero energetico. Il totale degli scarti
costituisce circa il 20% del materiale raccolto per
via differenziata; se sommati al rifiuto urbano residuo
attualmente generato, lo incrementano del 27%
portando il quantitativo complessivo a 16,1 milioni
di tonnellate all’anno, di cui 15,7 possono essere
avviate a recupero energetico.An effective separate collection of municipal
waste is a necessary condition for a high-quality
recycling system, with the aim of preserving natural
resources and reducing impacts on environment. The
quantification of residual municipal waste is essential
for the proper planning of an effective management
system, in particular for the definition of the treatment
capacity needed in a region or a country. The municipal
waste not suitable for material recovery is composed
by the unsorted municipal waste and by the
residual waste flows from the treatment of municipal
waste collected separately. While the first is effectively
monitored and easily quantifiable, the second one
must be estimated and varies with the separate collection
rate and its quality. Residual waste must be managed considering the potential environmental impacts
and preferring incineration with energy recovery to
landfill disposal; in Italy in 2018, 22% of municipal
urban waste was disposed in landfill. The aim of this
study is the assessment of residual waste flows from
material recovery operations of municipal waste from
separate collection. The analysis was focused on the
main fractions (organic fraction, paper and carboard,
plastics, glass, wood, metals) that are representative
for the 88% of the municipal waste collected separately.
The material recovery operations were divided in
three main stages: separation of different fractions collected
on a multi-material basis, selection of each fraction
in order to remove inappropriate materials from
the recoverable ones, recycling processes. In each
treatment stage, a flow of mixed waste is generated; it
can’t be sent to material recovery and it is sent to
alternative treatments based on its composition. As far
as possible, public data representative of the national
average were used. When the amount of residues was
not declared, it has been assessed considering treatment
efficiencies or the amount of avoided use of raw
materials from natural resources. In order to include in
the analysis all the municipal waste collected and not
only the main fractions (on which this analysis was
focused), the other minor fractions of separate collection
(for example household construction and demolition
waste, household bulky waste) were assessed,
assuming that the treatment residues suitable for energy
recovery account for the 10% of the total waste
flow. The analysis considered the Italian municipal
waste production in 2018 (30,2 million tons) when the
average separate collection rate was 58%. The results
show that the treatment of waste collected separately
generates 3,4 million tons of mixed waste: 3 million
are suitable for incineration with energy recovery.
These residues account for 20% of total waste from
separate collection; they increase the amount of residual
municipal waste (that per se represents the 42% of
total municipal waste production) by 27%; the municipal
waste not suitable for material recovery managed
in 2018 was 16,1 million tons; 15,7 million tons were
suitable for incineration with energy recovery
