Incineration

  • (Baghouse) A fabric filtration system (baghouse) consists of a number of filtering elements (bags) along with a bag cleaning system contained in the main shell structure with dust hoppers. Particulate-laden gas passes through the bags so that the particles are retained on the upstream side of the fabric, thus cleaning the gas (2.3-7)
  • (Baghouse) Our incinerators are designed to ensure Dioxins, furans, and similar gaseous components are destroyed using homogeneous high temperature (> 850°C), ensuring there is an excess of oxygen (>6 %) and sufficient residence time at high temperatures to make sure all 3 conditions are met.
  • (Just more information about Incinerators) In newer incinerators, air pollution control devices such as air filters capture and concentrate some of the pollutants; but they don’t eliminate them. The captured pollutants are transferred to other by-products such as fly ash, bottom ash, boiler ash/ slag, and wastewater treatment sludge that are then released into the environment.
  • (Incinerators in California) Significant new health concerns have been raised about emissions of ultrafine particles, including lead and other toxic metals, which cannot be captured by air filters. When inhaled, these nanoparticles can lodge deep in the lungs, enter the bloodstream, and raise the risk of heart attacks, cancer, and neurological disorders.
  • (Japan’s Environmental Standards)  furnaces (whether suspension-fired, grate-fired, mass-fired, air curtain incinerators, or fluidized bed-fired), and pyrolysis/combustion units. Municipal waste combustion units do NOT include pyrolysis or MWC units located at a plastics or rubber recycling unit (6). 

Synopsis: While air filters will mitigate some of the toxic gases produced by incinerators, they will not be able to completely purify and remove all of the harmful products. Additionally, there seem to be multiple types/specifications of air filters (e.g. baghouse). The pushback against incinerators seems to be expected. 

Overall Conclusion: Air filters will not take away all noxious products of incinerators. Both plastics/wool, wood, and hair seem to produce harmful chemicals. For the booms that we use, is Mauritius planning to ship them away to other countries? As referenced, Japan has strong regulations and well-monitored incinerators that will mitigate the byproducts. There was a brief mention of oyster mushrooms or other bacteria to naturally break up the oil spill with enzymes. That may be a better alternative or a method to accompany natural fiber booms.
