L’incenerimento cerca di far sparire la frazione residua

  • Plasma arc plants are part of family of technologies competing with mass burn incinerators (gasification, pyrolysis and plasma arc/torch) with very little proven commercial track record

  • All claim NOT to be incinerators, but all involve two stages:

  • 1) the conversion of solid waste into a gas,

  • 2) the burning of the gas, producing many of the same problems as a regular incinerator

  • So the more appropriate names would be:

  • Gasifying incinerator

  • Pyrolyzing incinerator

  • Plasma arc incinerator

Il problema con tutte le tecnologie di gassificazione aumentano se si passa da progetti pilota su piccola scala a progetti industriali su scala commerciale.

Non c’e’ magia che annulli la chimica di base.

  • Non c’e’ magia che annulli la chimica di base.

  • Quello che entra = quello che esce

  • Abbiamo bisogno di attenti studi di bilanci di massa per vedere dove finiscono il mmercurio, l’arsenico, il cadmio, il piombo, il cloro, il fluoro, e il bromo :nei fanghi, nei prodotti metallici, nelle ceneri leggere o nell’aria.

  • Il problema finale riguarda la tematica delle nanoparticles. Al momento queste non vengono ne’ regolamentate, ne monitorate ma hanno delle conseguenze sulla salute molto gravi..

  • L.A. dropped plant from its plan – because it hasn’t operated for 1000 hours in a one year period

  • Other communities in California and British Columbia have cancelled project

Modern incinerators use activated carbon filters to remove mercury

  • Modern incinerators use activated carbon filters to remove mercury

  • This carbon is part of the fly ash, and this should then be a SINK for the mercury (and sent to special facilities for recovery or containment)

  • However if you put the fly ash back into the furnace then you will release ALL the mercury again

  • There is only place left for the mercury to go (and other volatile metals) and that is into the AIR.

When PVC was fed into the high-temperature melter, a significant quantity of PCDD/Fs, cadmium and lead was emitted.

  • When PVC was fed into the high-temperature melter, a significant quantity of PCDD/Fs, cadmium and lead was emitted.

  • Wet scrubbing with rapid quenching, as well as a low temperature two-step fine filtration, or both of them together cannot effectively control the volatile metal species and gas-phase PCDD/Fs.

  • The removal of PVC from the feed waste stream must also be effective to reduce the emissions of the PCDD/Fs, cadmium and lead species.

They also claim that they will have no fly ash because they are going to recycle it back into the process.

Engineering consultants’ view:

  • Engineering consultants’ view:

  • “Many of the perceived benefits of gasification and pyrolysis over combustion technology proved to be unfounded. These perceptions have arisen mainly from inconsistent comparisons in the absence of quality information.”

“…a decision has been taken within Lurgi to discontinue marketing gasification and pyrolysis technologies for waste conversion applications.

  • “…a decision has been taken within Lurgi to discontinue marketing gasification and pyrolysis technologies for waste conversion applications.

  • This decision has come after rigorous analysis of market requirements, technical feasibility and economic sensitivities of gasification and pyrolysis of waste, as applied by Lurgi and our competitors.

  • We recognize there is a positive bias towards gasification/pyrolysis amongst politicians and environmentalists. However, we are in no doubt that in the short to medium term neither technology will be developed and commercially proven to the point where it can compete.”
