Incineration, the combustion of organic material such as waste with energy recovery, is the most common WtE implementation. All new WtE plants in OECD countries incinerating waste (residual MSW, commercial, industrial or RDF) must meet strict emission standards, including those on nitrogen oxides (NO x), sulphur dioxide (SO 2), heavy metals and dioxins.
Incineration is a waste treatment process that involves the combustion of substances contained in waste materials. [1] Industrial plants for waste incineration are commonly referred to as waste-to-energy facilities. Incineration and other high-temperature waste treatment systems are described as "thermal treatment".
The advantages of the incineration are reduction of volume and mass by burning, reduction to a percentage of sterile ash, source of energy, increase of income by selling bottom ash, and is also environmentally acceptable. The disadvantages of incineration are the following: [1] higher cost and longer payback period due to high capital investment
The typical plant with a capacity of 400 GWh energy production annually costs about 440 million dollars to build. Waste-to-energy plants may have a significant cost advantage over traditional power options, as the waste-to-energy operator may receive revenue for receiving waste as an alternative to the cost of disposing of waste in a landfill, typically referred to as a "tipping fee" per ton ...
Flue-gas desulfurization (FGD) is a set of technologies used to remove sulfur dioxide (SO 2) from exhaust flue gases of fossil-fuel power plants, and from the emissions of other sulfur oxide emitting processes such as waste incineration, petroleum refineries, cement and lime kilns.
A waste converter is a machine used for the treatment and recycling of solid and liquid refuse material. A converter is a self-contained system capable of performing the following functions: pasteurization of organic waste; sterilization of pathogenic or biohazard waste; grinding and pulverization of refuse into unrecognizable output; trash compaction; dehydration.
The power plants are classified, based on ownership, as either: Fully owned by the Federal Government of Nigeria (FGN). There is a plan to privatize these power plants. Owned by the Niger Delta Power Holding Company (NDPHC). The NDPHC is owned by the three tiers of government in Nigeria (Federal, State, and Local).
However the energy balance of the process is not high, as sludge needs drying before incinerating. [2] Sewage sludge can be incinerated in mono-incineration or co-incineration plants. In co-incineration, sewage sludge is not the only fuel and it can be processed at coal fired power plants, cement plants and in some waste incineration facility. [3]
