Waste Incineration Plants (also known as WtE facilities) should not be seen as a replacement for material recycling.
WtE is designed to complement recycling programs because not all waste is feasible to recycle.
Incineration is an engineering process that uses thermal decomposition in a highly oxidative environment to decompose organic molecules into simple compounds, predominantly carbon dioxide and water.
A necessary property of the waste material is that it be combustible. Incineration is a waste treatment technology that involves the combustion of organic materials and/or substances.
For example, using incinerators medical wastes are converted into ash, flue gases, particulates and heat, which can in turn be used to generate electricity.
Incineration is a proven means for the destruction of many organic wastes. Information relating to the design, operation, and performance of incineration systems is presented. Incineration is the burning of waste with or without energy recovery.
Britain's Royal Commission on Environment findings in 1993 maintained that incineration is an efficient way of recovering the energy present in household wastes, in order to generate electricity or provide steam or hot water.
Incineration is one of the best methods of reducing the volume and hazard of organic hazardous wastes. Through incineration, more than 90 percent of the volume of the original waste is typically reduced. Incineration is a waste treatment technology that involves the combustion of organic materials and/or substances. Incineration and other high temperature waste treatment systems are described as “thermal treatment”.
Incineration of waste materials converts the waste into incinerator bottom ash, flue gases, particulates, and heat, which can in turn be used to generate electric power.
The flue gases are cleaned of pollutants before they are dispersed in the atmosphere. Incinerators would emit a wide range of pollutants in their stack gases, ashes and other residues unless they are regularly tested and inspected by the operator and the local Environment Agencies to avoid the emissions which in the past have bedevilled this technology.
However, the concerns about Dioxin and other harmful emissions from incineration plants should now have been solved by the Waste Incineration Directive (WID) which has provided legislation which has ensured that very stringent regulatioory limts now apply to all solid waste management incinerators. These regulations are enforced by the environment agencies in each member state.
The filters used to clean incinerator stack gases produce solid and liquid toxic wastes, which also need to be disposed. Municipal waste incineration is still the first cause of dioxin pollution, according to a 1999 UNEP study. Over the past few years, many countries have updated their old incinerators or built new ones so eventually that will change.
In doing so, they have taken advantage of improved technologies for air pollution control. This has resulted in a substantial reduction in toxic emissions. Although this is an improvement, toxic waste production is still a serious global issue. In fact, the problem has now shifted, and more dioxins and other toxic substances are appearing in the ashes, therefore creating new disposal and pollution problems.
The European Union has introduced measures to prevent or reduce, as far as possible, air, water and soil pollution caused by the incineration or co-incineration of waste, as well as the resulting risk to human health.
These measures include a prior authorisation requirement for incineration and co-incineration plants, and emission limits for certain pollutants released to air or to water.
A first of our waste incineration plant facts is that a “burner” (this being the derogatory term of the anti-incinerator capaigners) is an important facility for the preservation of public health as it involves protecting the environment in a number of ways. Unless the waste materials are properly disposed of by the waste incinerator plant, […]
We were recently asked; “What is Commercial Composting” and since one person asked we wrote a definition, as follows below: Commercial composting is the composting carried out principally as a method of waste disposal that diverts this organic waste away from landfills. If the feedstock is green waste or another “MSW residual waste” organic material […]
Windrow composting is a way of generating compost by piling organic matter into extended rows or arc-like piles. The piles are turned over by large machinery to preserve even levels of heat, humidity, and oxygen content. Piles will usually range from four to eight feet tall and 14-16 feet in length. Windrow composting is a […]
Progressive cities and many urban centers around the world are now installing large-scale in-vessel composting systems as part of their total MSW management. Large scale in-vessel composting, which makes high quality compost through the use of enclosed “reactors” that closely monitor temperature and oxygen levels throughout the biodegradation of organic materials, is popular. In-vessel composting […]
