6 All’età di 16 anni i ragazzi di oggi hanno già guardato
oltre spot pubblicitari. Paul Hawken The Ecology of Commerce

7 This is colonialism in time!
Viviamo su questo pianeta come se ne avessimo un altro su cui trasferirci… Non possiamo continuare a vivere in una società “usa e getta” su un pianeta finito This is colonialism in time! We are robbing our own children and grandchildren Con le discariche non facciamo altro che SOTTERRARE le prove Gli inceneritori non fanno che BRUCIARE le prove Dobbiamo affrontare il vero problema …

8 Il problema non è: “come eliminare i rifiuti”, ma piuttosto come NON produrli

9 Our task is to fight the throwaway ethic & over-consumption

10 Not only is over-consumption giving us a waste crisis but also…

11 Over-consumption is giving us a Global crisis

12 We are imposing a linear society on a planet that functions in circles

31 Arguments against incineration
Emissioni tossiche nell’atmosfera Produzione di ceneri tossiche Pubblica opposizione. Incineration is anti-democratic Costi finanziari. Incineration is a poor investment Produzione di energia (spreco di energia) Ci sono migliori alternative – Zero Waste 2020

32 1.Gli inceneritori producono ceneri tossiche

33 MODERN TRASH INCINERATOR
ELECTRICITY TURBINE WET SCRUBBER SECONDARY CHAMBER STEAM DE-NOX CHUTE TEMP < 200oC FABRIC FILTER BOILER SEMI- DRY SCRUBBER Ca(OH) 2 SUSPENSION ACTIVATED CHARCOAL GRATES AMMONIA INJECTION TRASH FLY ASH BOTTOM ASH

34 Politicians often approve incineration before they have any idea where the toxic ash is going to go!

35 Ash disposal in other countries
Germany puts fly ash into nylon bags and buries them in salt mines (like nuclear waste) Some Japanese incinerators vitrify the ash Denmark has a wonderful solution … it sends its ash to Norway! The Netherlands puts the fly ash into asphalt and the bottom ash into road building!

36 2. Gli inceneritori emettono gas tossici

37 AIR EMISSIONS CO2 + H2O ACID GASES: HCI, HF, SO2 NOx TOXIC METALS:
Pb, Cd, Hg, As, Cr etc NEW COMPOUNDS: PCB’s PCDDs (DIOXINS) PCDFs (FURANS) ETC NANO PARTICLES

38

39

40 Catalytic oxidizers Brominated/chlorinated dioxins and furans Polycyclic aromatic hydrocarbons Chlorinated hydrocarbons

41 The dangers of nanoparticles
Nanoparticles are not efficiently captured by air pollution control devices, travel long distances, penetrate deep into the lungs

42

43

44 Nano Pathology Nano particles are so small they can easily cross cell membranes Including the blood brain barrier and the nuclear membrane Ferry toxic metals into the brain Stabilized free radicals cause oxidative stress - inflammation - many degenerative diseases

45 Aggregati di Piombo, Bario, Cromo, Ferro e Silicio in Cervello.

46 Dioxins - major concerns
Dioxins accumulate in animal fat One liter of cows’ milk gives the same dose of dioxin as breathing air next to the cows for EIGHT MONTHS (Connett and Webster, 1987). Dioxins steadily accumulate in human body fat. The man cannot get rid of them BUT A woman can… …by having a baby! The highest dose of dioxin goes to the fetus and then to the new born infant via breastfeeding, and dioxins interfere with hormones which control sexual and mental development

47 WE WANT DIOXIN OUT OF OUR BABIES!

48 Institute of Medicine, 2003 Fetuses and breastfeeding infants may be at particular risk from exposure to dioxins due to their potential to cause adverse neurodevelopmental… and immune system effects…

49 Institute of Medicine, 2003 …The committee recommends:
1) the government place a high public health priority on reducing dioxin intakes by girls and young women in the years well before pregnancy is likely to occur 2) (By) substituting low-fat or skim milk, for whole milk…and other foods lower in animal fat

50 Thermal treatment is dangerous
In cities because the fine particles can get deep down into our lungs In rural areas because the dioxins can get into our food

51 While modern incinerators have reduced dioxin emissions there is no real accountability in most countries

52 YOU NEED THREE THINGS TO PROTECT THE PUBLIC FROM TOXIC EMISSIONS.
STRONG REGULATIONS ADEQUATE MONITORING TOUGH ENFORCEMENT IF ANY LINK IS WEAK THE PUBLIC IS NOT PROTECTED

53 3. Incineration is extremely unpopular
In the US over 300 incinerator proposals defeated since 1985 US has not permitted a new trash incinerator since 1995.

54 4. Incineration is a poor investment
Most of the money spent on incinerators goes into complicated machinery and leaves the community, whereas The money spent on the alternatives goes into jobs and stays in the community.

55 5. Incineration is a waste of energy!
3-4 times more energy saved by reusing objects and recycling materials in waste stream. In Italy a law passed in 1996 allows incinerators to sell electricity at three times the price from other sources. The public pays! This explains the current rush to build new incinerators in Italy even though they are so unpopular. The Alberta government has just provided a $20 million subsidy for a new incinerator in Edmonton

56 Energy Comparison: Recycling versus incineration (ICF consulting, 2005)

57 6. Incineration is not sustainable

58 “Anche rendendo sicuro l’incenerimento,
Esso non sarà mai una cosa sensata. Semplicemente non ha senso spendere così tanti soldi Per distruggere risorse che dovremmo Risparmiare per il futuro.” (PC)

59 7. THERE ARE BETTER and SUSTAINABLE ALTERNATIVES TO INCINERATION

60 The ZERO 2020 strategy

61 Progettare i rifiuti all’esterno del ciclo produttivo
NO ALLA SOCIETA’ USA E GETTA SÌ A UNA SOCIETA’ SOSTENIBILE RIFIUTI ZERO 2020 SPOSTARSI A MONTE Progettare i rifiuti all’esterno del ciclo produttivo NO ALL’INCENERIMENTO NO ALLE DISCARICHE

62 I rifiuti non sono un problema tecnologico sono un problema di progettazione industriale

63 Per ottenere Zero Rifiuti
Occorrono tre cose RESPONSABILITA’ INDUSTRIALE (a monte) RESPONSABILITA’ della COMUNITA’ (a valle) 3) Una BUONA LEADERSHIP POLITICA (per saldare insieme entrambe)

64 RESPONSABILITA’ INDUSTRIALE
1. PROGETTO INDUSTRIALE DI SOSTENIBILITA’ 2. PRODUZIONE PULITA - riduzione di elementi tossici nei prodotti e nella produzione 3. RESPONSAILITA’ DELLA CATENA DI PRODUZIONE (EPR = EXTENDED PRODUCER RESPONSIBILITY)

65 Extended Producer Responsibilty
In futuro le imprese produttrici dovrebbero considerare di dover ritirare I propri prodotti e confezioni, dopo l’uso leggi si stanno gia’ muovendo in questa direzione.

66 Extended Producer Responsibilty
XEROX CORPORATION EUROPE recupero di vecchie macchine fotocopiatrici da oltre 16 paesi Raccolte in enormi depositi in Olanda, dove vengono smontate Oltre il 95% dei materiali viene riutilizzato o riciclato! Con un risparmio di $76 milioni nel 2000!!

67 on average each bottle reused 18 times
ONTARIO, CANADA The Beer industry has used refillable glass bottles for over 50 years 98% recovered on average each bottle reused 18 times Refillable glass bottles 11 cents cheaper per serving than disposable bottles. 2000 jobs in collection and cleaning No cost to municipality Packaging costs internalized

68 COMMUNITY RESPONSIBILITY Classification of Discarded materials
1. Avoidables (e.g. throwaway plastic objects) 2. Reusables (e.g furniture, appliances) 3. Toxics (e.g paint, oil, batteries) 4. Compostables (e.g. food scraps) 5. Recyclables (e.g. paper, glass, metals) 6. Residuals Residuals = “bad industrial design”

69 RESPONSABILITA’ della COMUNITA’
Community responsibility begins with Source Separation (porta a porta) One container for compostables (i.e. the organic fraction) One (or more) containers for the recyclables One container for the residuals

86 Come gestiamo la frazione residua: un momento cruciale della filosofia Rifiuti Zero
Incineration attempts to make the residuals disappear Zero Waste 2020 needs to make the residuals VERY VISIBLE, because… Frazione Residua = cattiva progettazione industriale We need better (sustainable) industrial design for the 21st Century

87 Nova Scotia, Canada They have built IMPIANTO DI SEPARAZONE della FRAZIONE RESIDUA These buildings are built in front of the landfill - NO residuals can go to landfill without being screened.

Consiglio: La creazione di un “Istituto Nazionale per una Società Sostenibile” Con funzione di coordinamento della ricerca locale e regionale presso il Centro per la Ricerca e lo Screening sulla Frazione Residua (= cattiva progettazione industriale)

104 Incenerendo … 1 tonnellata di ceneri tossiche che nessuno vuole!!!
… si convertono 3 tonnellate di rifiuti in: 1 tonnellata di ceneri tossiche che nessuno vuole!!!

105 Con la strategia Rifiuti Zero
Si convertono TRE tonnellate di rifiuti in: 1 tonnellata di risorse compostabili 1 tonnellata di risorse riciclabili e 1 tonnellata di consapevolezza!

106 Messaggio all’industria:
Se non possiamo riutilizzarlo, riciclarlo o compostarlo, l’industria non dovrebbe produrlo!!! We need better industrial design for the 21st Century

107 IMPIANTO DI SEPARAZONE e CENTRO DI RICERCA della FRAZIONE RESIDUA
Will Italy be the first to build an impianto di separazone e centro di ricerca della frazione residua?

108 Progress towards Zero Waste around the world
Note over 50% of communities in New Zealand have declared a Zero Waste strategy

128 Another three reasons why ZW 2020 is better than incineration
Jobs! Jobs !! Jobs !!!

129 Nuova Scozia (Canada) 50% dei rifiuti sottratto alle discariche in 5 anni (Halifax ~ 60%) 1000 posti di lavoro creati dall’aprile 1996 Altri 2000 posti di lavoro creati in industrie che usano i materiali separati Nearly all the separated materials are re-used in Nova Scotia’s own industries.

130 Abbiamo bisogno di leader politici e industriali dotati di
UNA BUONA LEADERSHIP Abbiamo bisogno di leader politici e industriali dotati di grandi visioni immaginazione e … CHE NON SIANO NOIOSI

131 Le persone noiose … risolvono i problemi nel posto sbagliato !

132 Chi tenta di risolvere il problema A VALLE pensa …
1. UNA TAZZA 2. UN SECCHIO 3. UNA POMPA A PEDALE 4. UNA POMPA ELETTRICA

133 Chi tenta di risolvere il problema A MONTE pensa …

134 Einstein A clever person solves a problem A genius avoids it!

135 Un pizzico di creatività a monte può far risparmiare milioni a valle

136 Conclusioni The Zero Waste Strategy addresses four key issues:
1. Individuals must be more careful about what they buy 2. Industries must be more careful about what they make 3. Communities must be more responsible in the way that discarded materials are collected and handled 4. Education has a key role in linking waste management to sustainability and the fight against Global Warming

137 Conclusioni The throwaway society contributes to global warming by wasting finite resources and wasting energy Landfills and incinerators do not solve the problem but only hide the symptoms The Zero Waste strategy by intensifying reuse, recycling, and composting and by tackling overconsumption and poor industrial design, reduces global warming and the other impacts of primary processing

138 Zero Waste 2020 Sustainable Education agriculture Architecture
Industrial design Sustainable Energy Community development Sustainable Economic Development

139 Conclusioni Non abbiamo bisogno di inceneritori! Esistono alternative
migliori più sicure, migliori per l’economia, migliori per i vostri figli, e migliori per il pianeta.

140 But in Italy there remains a major obstacle:

141 THE BAD LAW Level of Pollution Level of corruption

142 THE GOOD LAW Level of Pollution Public participation

143 Dio ricicla, il diavolo brucia

144 The Battle Hymn of Garbage
(Chorus) We don’t want incineration We know there’s a better way!

145 The Battle Hymn of Garbage
While we recognize our landfills All are swelling with the waste This doesn’t justify A bad decision made in haste! Let us put our heads together So the problem may be faced And we must do it now!

146 The Battle Hymn of Garbage
(Chorus) We don’t want incineration We know there’s a better way!

147 The Battle Hymn of Garbage
Mine eyes have seen the garbage That’s a smoldering on the grate We must stop incineration Before it is too late Unless we wish the dangers We had better separate And we must do it now!

148 The Battle Hymn of Garbage
(Chorus) We don’t want incineration We know there’s a better way!

149 Extra slides

150 No accountability Typically incinerators tested once or twice a year using 6 hour tests to check dioxin in flue gas. These are collected with advanced notice to the operator Thus, 18 (36?) hours of IDEAL data is being used to ESTIMATE 8000 hours of REAL operation. THIS IS NOT SCIENTIFIC! Two week sampling (The Amesa system) is now available. This system allows collection of 26 X two-week samples per year - i.e. continuous sampling Most incinerator operators are not using the two week sampling system or other scientific monitoring.

151 Hiding the name! Waste Incineration is so unpopular with the public that incinerator promoters have used a variety of names for plants that burn trash: In US, they were called Resource Recovery Facilities and Waste to Energy plants. In UK they were called Energy from Waste (EfW) facilities. In Italy and France they are called “Thermal Valorization” and “Thermal Optimization” Now all the rage are the descriptions: gasification, pyrolysis and plasma arc facilities.

152 The most appropriate name for incinerators
RDF Resource Destruction Facilities!

153 Dobbiamo copiare la natura
La natura non produce rifiuti! I rifiuti sono un’invenzione dell’uomo Società sostenibile = società a rifiuti zero Zero Waste is an idealistic goal, but Zero Waste 2020 puts this goal into a realistic time frame
