Incineration is a waste treatment process that involves the combustion of organic substances contained in waste materials. Incineration of waste materials converts the waste into ash , flue gas and heat. The ash is mostly formed by the inorganic constituents of the waste and may take the form of solid lumps or particulates carried by the flue gas. The flue gases must be cleaned of gaseous and particulate pollutants before they are dispersed into the atmosphere. In some cases, the heat generated by incineration can be used to generate electric power.

Incineration with energy recovery is one of several waste-to-energy technologies such as gasification , pyrolysis and anaerobic digestion. While incineration and gasification technologies are similar in principle, the energy produced from incineration is high-temperature heat whereas combustible gas is often the main energy product from gasification.

Incineration and gasification may also be implemented without energy and materials recovery. In several countries, there are still concerns from experts and local communities about the environmental effect of incinerators see arguments against incineration.

In some countries, incinerators built just a few decades ago often did not include a materials separation to remove hazardous, bulky or recyclable materials before combustion. These facilities tended to risk the health of the plant workers and the local environment due to inadequate levels of gas cleaning and combustion process control.

Most of these facilities did not generate electricity. Garbage trucks often reduce the volume of waste in a built-in compressor before delivery to the incinerator. In many countries, simpler waste compaction is a common practice for compaction at landfills.

Incineration has particularly strong benefits for the treatment of certain waste types in niche areas such as clinical wastes and certain hazardous wastes where pathogens and toxins can be destroyed by high temperatures.

Examples include chemical multi-product plants with diverse toxic or very toxic wastewater streams, which cannot be routed to a conventional wastewater treatment plant. Waste combustion is particularly popular in countries such as Japan, Singapore and the Netherlands, where land is a scarce resource. Denmark and Sweden have been leaders by using the energy generated from incineration for more than a century, in localised combined heat and power facilities supporting district heating schemes.

They were originally known as destructors. An incinerator is a furnace for burning waste. Modern incinerators include pollution mitigation equipment such as flue gas cleaning. There are various types of incinerator plant design: moving grate, fixed grate, rotary-kiln, and fluidised bed. The burn pile is one of the simplest and earliest forms of waste disposal, essentially consisting of a mound of combustible materials piled on the open ground and set on fire. Burn piles can and have spread uncontrolled fires, for example, if the wind blows burning material off the pile into surrounding combustible grasses or onto buildings.

As interior structures of the pile are consumed, the pile can shift and collapse, spreading the burn area. Even in a situation of no wind, small lightweight ignited embers can lift off the pile via convection , and waft through the air into grasses or onto buildings, igniting them.

The burn barrel is a somewhat more controlled form of private waste incineration, containing the burning material inside a metal barrel, with a metal grating over the exhaust. The barrel prevents the spread of burning material in windy conditions, and as the combustibles are reduced they can only settle down into the barrel. The exhaust grating helps to prevent the spread of burning embers. Most urban communities ban burn barrels and certain rural communities may have prohibitions on open burning, especially those home to many residents not familiar with this common rural practice.

As of [update] in the United States, private rural household or farm waste incineration of small quantities was typically permitted so long as it is not a nuisance to others, does not pose a risk of fire such as in dry conditions, and the fire does not produce dense, noxious smoke.

A handful of states, such as New York, Minnesota, and Wisconsin, have laws or regulations either banning or strictly regulating open burning due to health and nuisance effects. The typical incineration plant for municipal solid waste is a moving grate incinerator.

The moving grate enables the movement of waste through the combustion chamber to be optimized to allow a more efficient and complete combustion. The waste is introduced by a waste crane through the "throat" at one end of the grate, from where it moves down over the descending grate to the ash pit in the other end. Here the ash is removed through a water lock. Part of the combustion air primary combustion air is supplied through the grate from below.

This air flow also has the purpose of cooling the grate itself. Cooling is important for the mechanical strength of the grate, and many moving grates are also water-cooled internally.

Secondary combustion air is supplied into the boiler at high speed through nozzles over the grate. It facilitates complete combustion of the flue gases by introducing turbulence for better mixing and by ensuring a surplus of oxygen. In order to comply with this at all times, it is required to install backup auxiliary burners often fueled by oil , which are fired into the boiler in case the heating value of the waste becomes too low to reach this temperature alone.

In Scandinavia , scheduled maintenance is always performed during summer, where the demand for district heating is low. Often, incineration plants consist of several separate 'boiler lines' boilers and flue gas treatment plants , so that waste can continue to be received at one boiler line while the others are undergoing maintenance, repair, or upgrading.

The older and simpler kind of incinerator was a brick-lined cell with a fixed metal grate over a lower ash pit, with one opening in the top or side for loading and another opening in the side for removing incombustible solids called clinkers.

Many small incinerators formerly found in apartment houses have now been replaced by waste compactors. The rotary-kiln incinerator [12] is used by municipalities and by large industrial plants. This design of incinerator has two chambers: a primary chamber and secondary chamber. The primary chamber in a rotary kiln incinerator consists of an inclined refractory lined cylindrical tube. The inner refractory lining serves as sacrificial layer to protect the kiln structure.

This refractory layer needs to be replaced from time to time. In the primary chamber, there is conversion of solid fraction to gases, through volatilization, destructive distillation and partial combustion reactions. The secondary chamber is necessary to complete gas phase combustion reactions. The clinkers spill out at the end of the cylinder. A tall flue-gas stack, fan, or steam jet supplies the needed draft. Ash drops through the grate, but many particles are carried along with the hot gases.

The particles and any combustible gases may be combusted in an "afterburner". A strong airflow is forced through a sandbed. The air seeps through the sand until a point is reached where the sand particles separate to let the air through and mixing and churning occurs, thus a fluidized bed is created and fuel and waste can now be introduced.

The bed is thereby violently mixed and agitated keeping small inert particles and air in a fluid-like state. This allows all of the mass of waste, fuel and sand to be fully circulated through the furnace. Furniture factory sawdust incinerators need much attention as these have to handle resin powder and many flammable substances. Controlled combustion, burn back prevention systems are essential as dust when suspended resembles the fire catch phenomenon of any liquid petroleum gas. The heat produced by an incinerator can be used to generate steam which may then be used to drive a turbine in order to produce electricity.

Incineration has a number of outputs such as the ash and the emission to the atmosphere of flue gas. Before the flue gas cleaning system , if installed, the flue gases may contain particulate matter , heavy metals , dioxins , furans , sulfur dioxide , and hydrochloric acid. If plants have inadequate flue gas cleaning, these outputs may add a significant pollution component to stack emissions. In a study from , Delaware Solid Waste Authority found that, for same amount of produced energy, incineration plants emitted fewer particles, hydrocarbons and less SO 2 , HCl, CO and NO x than coal-fired power plants, but more than natural gas—fired power plants.

The most publicized concerns from environmentalists about the incineration of municipal solid wastes MSW involve the fear that it produces significant amounts of dioxin and furan emissions. The EPA announced in that the safe limit for human oral consumption is 0. In , The Ministry of the Environment of Germany, where there were 66 incinerators at that time, estimated that " Chimneys and tiled stoves in private households alone discharge approximately 20 times more dioxin into the environment than incineration plants.

According to the United States Environmental Protection Agency , [9] the combustion percentages of the total dioxin and furan inventory from all known and estimated sources in the U.

Thus, the controlled combustion of waste accounted for In , before the governmental regulations required the use of emission controls, there was a total of 8, Today, the total emissions from the plants are Studies conducted by the US-EPA [19] demonstrated that the emissions from just one family using a burn barrel produced more emissions than an incineration plant disposing of metric tons short tons of waste per day by and five times that by due to increased chemicals in household trash and decreased emissions by municipal incinerators using better technology.

However, the same researchers found that their original estimates for the burn barrel were high, and that the incineration plant used for comparison represented a theoretical 'clean' plant rather than any existing facility. Their later studies [21] found that burn barrels produced a median of Most of the improvement in U. The breakdown of dioxin requires exposure of the molecular ring to a sufficiently high temperature so as to trigger thermal breakdown of the strong molecular bonds holding it together.

Small pieces of fly ash may be somewhat thick, and too brief an exposure to high temperature may only degrade dioxin on the surface of the ash. For a large volume air chamber, too brief an exposure may also result in only some of the exhaust gases reaching the full breakdown temperature. For this reason there is also a time element to the temperature exposure to ensure heating completely through the thickness of the fly ash and the volume of waste gases.

There are trade-offs between increasing either the temperature or exposure time. Generally where the molecular breakdown temperature is higher, the exposure time for heating can be shorter, but excessively high temperatures can also cause wear and damage to other parts of the incineration equipment.

A side effect of breaking the strong molecular bonds of dioxin is the potential for breaking the bonds of nitrogen gas N 2 and oxygen gas O 2 in the supply air. As the exhaust flow cools, these highly reactive detached atoms spontaneously reform bonds into reactive oxides such as NO x in the flue gas, which can result in smog formation and acid rain if they were released directly into the local environment.

These reactive oxides must be further neutralized with selective catalytic reduction SCR or selective non-catalytic reduction see below.

The temperatures needed to break down dioxin are typically not reached when burning plastics outdoors in a burn barrel or garbage pit, causing high dioxin emissions as mentioned above. While plastic does usually burn in an open-air fire, the dioxins remain after combustion and either float off into the atmosphere, or may remain in the ash where it can be leached down into groundwater when rain falls on the ash pile. Fortunately, dioxin and furan compounds bond very strongly to solid surfaces and are not dissolved by water, so leaching processes are limited to the first few millimeters below the ash pile.

The gas-phase dioxins can be substantially destroyed using catalysts, some of which can be present as part of the fabric filter bag structure. They are equipped with auxiliary heaters to ensure this at all times.

These are often fueled by oil or natural gas, and are normally only active for a very small fraction of the time. Further, most modern incinerators utilize fabric filters often with Teflon membranes to enhance collection of sub-micron particles which can capture dioxins present in or on solid particles.

For very small municipal incinerators, the required temperature for thermal breakdown of dioxin may be reached using a high-temperature electrical heating element, plus a selective catalytic reduction stage. Although dioxins and furans may be destroyed by combustion, their reformation by a process known as 'de novo synthesis' as the emission gases cool is a probable source of the dioxins measured in emission stack tests from plants that have high combustion temperatures held at long residence times.

As for other complete combustion processes, nearly all of the carbon content in the waste is emitted as CO 2 to the atmosphere.

In the latter decades of the 20th century, the creation of new lean production methods set the standard for process improvement and created the framework for the Lean Manufacturing movement. By increasing value and reducing the amount of work required to perform tasks, many companies experienced a transformation that allowed them to significantly improve competitiveness within their industries. A core principle in lean methodology is the removal of waste within an operation. And in any business, one of the heaviest drains on profitability is waste.

The Berne plant of United Technologies Automotive (UTA) supplies exterior mirrors, often 2 weeks of inventory requiring large amounts of storage space. Plant.

The results of these early tests were promising, Made In Space representatives said, so the company intends to ratchet things up. Made In Space has facilities on the Ames campus. One of Made In Space's main goals is to help establish a robust off-Earth economy, which, in turn, could enable humanity to extend its footprint out into the solar system. The material has the potential to be markedly superior to traditional silica-based optical fiber, but it's difficult to make on Earth because our planet's strong gravity induces imperfections in the ZBLAN crystal lattice, Made In Space representatives have said. So it could be a good gateway product, demonstrating the commercial viability of off-Earth manufacturing and allowing Made In Space to turn a tidy profit at the same time.

According to Greenpeace Southeast Asia, imports of plastic waste to Thailand jumped from , tons in to , tons in Last year, Japan was the biggest exporter of plastic garbage to the Kingdom at , tons, followed by Hong Kong at 99, tons and the United States at 84, tons.

When I first meet Chan King Ming at the Chinese University of Hong Kong, it is difficult to imagine that the region is facing an environmental disaster. There is not a single discarded plastic bottle or used newspaper in sight. But appearances are deceptive. Hong Kong may be clean on the surface, but its public services are straining to keep a lid on its rubbish. Despite attempts to clean up its act, the region produced 3.

Amager Bakke is a new, modern incineration plant in Copenhagen. It is also a lesson on questionable decision-making processes, poor project planning and economic and environmental failures. The history of the new incineration plant located in northeastern Amager goes back to 1. The new incinerator was built on the promise of greater benefits in terms of energy efficiency and the environment. The plant would also be able to burn biomass in case of waste shortages, which would create carbon-neutral energy and heat, as well as making economic sense 4.
