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 …
Il problema non è: “come eliminare i rifiuti”, ma piuttostocome NON produrli
Not only is over-consumption giving us a waste crisis but also…

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

Politicians often approve incineration before they have any idea where the toxic ash is going to go!
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!
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
Catalytic oxidizers Brominated/chlorinated dioxins and furans Polycyclic aromatic hydrocarbons Chlorinated hydrocarbons
The dangers of nanoparticles • Nanoparticles are not efficiently captured by air pollution control devices, • travel long distances, • penetrate deep into the lungs
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

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
WE WANT DIOXIN OUT OF OUR BABIES!
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…
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
Thermal treatment is dangerous • In citiesbecause the fine particles can get deep down into our lungs • In rural areas because the dioxins can get into our food
