Reduced pollutants and role of emissions treatment systems
Incineration is found to be a more eco-friendly treatment method than landfills due to
its reduced pollutant generation. Landfills usually release higher quantities of dioxin,
hydrocarbons, nitrogen oxides, greenhouse gases, non-methane organic compounds
and leachate fluids. Leachate water will destroy the underground water systems.
Comparing incineration with that of landfill process, methane gas is generated in landfills and the generation of this gas has to be controlled in order to avoid explosion. The
methane gas production also causes serious global warming issues. Whereas, in the
case of incineration process there is no generation of methane gas. More over as most
of the incineration plants are operated at 850 °C or even higher temperatures, most
of the germs and chemical hazardous materials are destroyed to the maximum level.
Further, the incineration treatment process can provide better control over the odour
and noise pollution. Existing incineration plants are equipped with suitable filters and
appropriate emission systems on par with pollution limits recommended by respective pollution control boards, Environmental Protection Agencies and Regulatory
Legislations.
Incinerators coupled with computerized monitoring system and metal recycling
The incineration plant units were equipped with a computer system to continuously monitor the operation efficiency and emission of products after completion
of process. The coupling of plants with computerized system will enable the operator to find out the particular problem and to sort out the exact solution for it in a more
precise manner. After incineration process, the metals will remain as such in many
cases as it possess higher melting points. The metallic residues can be collected from
the respective units and it can be reused for any other application before the disposal
stage.
Incinerators can operate in any weather
Incinerators operations are not dependent on weather changes, as they ignite waste
without any leakages. During drizzling season, waste cannot be disposed in landfills
because there is a possibility of washout and formation of leachates due to rain water
after the natural underground water system. Incineration plants can work non-stop
for 24 h and are more well-organized and effective in managing waste compared to
other treatment methods.
Cons of Incineration Method in BMWM System
Expensive Treatment Process
The infrastructure cost for the construction of incineration plants is very expensive. In
addition, the plants require trained manpower to operate by following exact standard
operation procedures and regular maintenance is an essential factor to monitor the
emission processes.
