Advantages and disadvantages of incineration
Answers
==========
There are a number of advantages to using incineration as a waste management method. Two of the primary advantages of incineration are that waste volumes are reduced by an estimated of 80-95%, and the need for land and landfill space is greatly reduced For urban areas, this can be especially important, as urban land is often at a premium.
Waste incineration plants can be located near where waste is generated, which decreases the costs and energy associated with transporting waste Through Waste-to-Energy processes, incineration can be used to produce electricity and heat that can be used to power and heat nearby buildings, and the ash produced can be used by the construction industry

Disadvantage
============
Incineration facilities are expensive to build, operate, and maintain The high costs associated with this method of waste disposal may encourage waste generators to seek other alternatives for dealing with their waste. These facilities also require skilled staff to run and maintain them.
Smoke and ash emitted by the chimneys of incinerators include acid gases, nitrogen oxide, heavy metals, particulates, and dioxin, which is a carcinogen While incineration pollution control technology is evolving to reduce these pollutants, it has been found that even with controls in place, some remaining dioxin still enterez

Answer:
advantages:
Incineration causes a significant reduction in the volume of waste. The reduction in the original volume and weight 95% and 75% respectively .
It helps providing a new able source and conserving valuable raw materials .
Bottom ash can be reused-as secondary mixtures for parking lots, paved roads etc.
Due to incineration, a large proportion of the organic compounds including putrescible and hazardous waste is destroyed. So there is a net reduction in the quantity of toxicity.
Incineration does not generate methane gas and reduces methane from landfills.
It provides better control over odour and noise .
disadvantages :
it causes atmospheric pollution if incinerators are not well maintained.
Incinerators are costly to construct, operate and regulate. Stringent emission for incinerators increase the cost of construction, operation and maintenance.
It lacks system flexibility. The demand for recycled and recovered material for different treatment methods is likely to change overtime.
Incineration process produces ash and wastewater from pollution control devices.
A huge amount of money required to purchase a foreign made incinerator.
Low-income countries often lacks adequately trained labor to operate and maintain incinerator systems.
Waste incineration mainly releases Carbon Monoxide which is a harmful gas.
