With a large number of population attracted to urban areas for work opportunities, solid waste management is one of the biggest problems that municipalities are combating in large urban areas. Traditionally dumped into landfills and treated at these sites, the method has repercussions on the environment. To address this, newer technologies such as incineration, recycling, gasification, or pyrolysis are replacing traditional landfills for the purpose.
Incineration is a waste management technology, wherein waste matter is burnt for the purpose of recovering energy. Typically, incinerators, air pollution control systems, heat recovery systems, combustion systems, waste receipt and handling systems, and combustion solid residue handling systems are the equipment of a land incinerator plant. During the process of incineration, the waste material is treated to be converted into gases, particles, and heat to be later used for electricity generation. The flue gases that are produced resultantly and are present in the dust of the system are treated to be free of pollutants before they are released into the atmosphere.
For incinerating plants, incinerator is significantly important which reduces solid municipal waste mass by 80% and volume by 90%, which depends on the composition of waste and the material that is recovered after incineration.
Presently, China is facing the biggest-ever challenge of uncurbed and exponential volume of refuse that is generated across cities in the country. To address this, China is constructing the largest waste-to-energy plant in the world. This incinerator, which is expected to be up and operating by 2020 is one of the 300 waste-to-energy plants that is on the development plans in China in the next three years.
In several other parts of the world as well, governments and municipal agencies are promoting the use of incineration techniques by means of funding for the development of these facilities. Capital grants, prudential borrowing, and infrastructure credits are the funding schemes that are offered for the development of these facilities. For example, in the U.K and New Zealand, due to higher taxes on landfill dumping, dumping agencies are seeking alternate waste disposal techniques, which in turn is driving the land incineration plants market.
