What does syngas mean?

Syngas is the name for a synthetic gas, which is produced via the gasification of biomass. The word biomass refers to a wide range of solids that can be burnt to produce energy, such as waste feedstock and garbage. Syngas is typically made up of hydrogen, carbon monoxide as well as carbon dioxide and methane in small amounts.

Gasification changes any carbon based matter into a synthetic gas, which is then used to generate power. Waste feedstock is a common material used for gasification. They are placed into the gasifier, which is an oxygen-starved environment, and the feedstock then syngas is produced. An enormous amount of heat required is required to produced syngas – up to 2500 degrees Celsius. Typically, the heating is produced by a process called direct heating, in which a small quantity of oxygen is added to the reactor.

What is the benefit of syngas?

Syngas is a gas which is much cleaner than those produced through burning fossil fuels such as coal and gas. In an age when emissions reduction is an important policy of many governments, and when many countries are legally obliged to reduce their carbon dioxide emissions, syngas technology has enormous potential. Syngas can be manufactured domestically, reducing dependence on foreign countries for fossil fuels.
In addition, this would generate jobs and growth in local economies. A further advantage of this technology is that syngas can be generated as part of the waste to energy process, which means that waste that would otherwise end up in the landfill gets dealt with cleanly and efficiently.

Are Syngas being practically applied today?

Absolutely. A great example can be found in New Bedford, Massachusetts, where the renewable energy company Ze-gen has run a demonstration facility for more than two years. The company injects biomass, which in this case is organic waste from municipal sources, and burns it to produce syngas. These syngas are much cleaner than gas produced from the gasification of coal, and they release much les carbon dioxide. The toxins that are produced either sink to the bottom of the chamber or are caught at the top in silica crust.

This test facility burns 1 ton of waste per hour, and in the US, where landfills are overflowing, the company has attracted considerable attention from investors. Last year, it was announced that they are planning to open a commercial and industrial facility in 2012. The future looks bright for syngas technology!

With the increasing threat of global warming, more and more nations and organizations are researching into and implementing alternative energy sources to replace more traditional energy sources. Apart from the threat of global warming, there is now an urgent emphasis to develop alternative energy because traditional energy is dependent of non-renewable sources such as oil, coal, uranium (nuclear) etc which are fast depleting and are plagued with frequent price surges.

However, when it comes to energy production through alternative energy sources, it does not always mean alternative sources to produce power. It can also mean utilizing alternative sources to manufacture products that are used daily, and that are more environmentally friendly. In the same way, wind, sun, water and geothermal heat are not the only sources through which energy can be produced; there are other sources such as food and agricultural waste, human and organic waste etc.

The bioconversion of food waste (biomass) means converting food waste into gas (gasification) and liquid fuels. These gases and/or liquids can be used as an alternative energy source or a means to manufacture environmentally friendly products. Bionconversion technologies are fast being developed and implemented around the world.

The most common result of the bioconversion of food waste is ethanol and biodiesel. Ethanol is produced through the biomass of grain; it is created by fermenting crops such as sugar cane, sugar beet or corn. However, the best quality ethanol is produced through the biomass of corns (starch) and sugar cane (sugar).

Biomass fermented ethanol can be used in vehicles and thus replace traditional fuels. As mentioned earlier, sugar and corn are its best sources, which is why food waste collected is perfect for extracting bioethanol because food waste is full of sugar and starch content.

Biodiesel is also obtained from the biomass of plants, but until a few years ago ethanol was considered to be more efficient than biodiesel. Extracting ethanol from plants is a very expensive due to the distillation process, but new bionconversion technologies for extracting biodiesel eliminate the need of the distillation process, saving considerable money. Biodiesel fuel when used produces very low levels of emissions, making it far safer for people as well as the earth as compared to traditional fuels.

These biofuels are just as efficient as traditional fuels and are being used in hybrid cars and boats, and even several small planes. Besides using them in your cars, you can also use them in your homes as they produce extremely low levels of emissions.

Some food waste is also used in the production of environment friendly products such as biodegradable plastics. Other than that, the packaging used for wrapping food can easily be recycled to reduce the amount of waste being dumped in landfills. The utilization of food waste to produce energy and environmentally friendly products greatly reduces the amount of waste being dumped in landfills.

Millions of tons of solid municipal waste are created in many country across the world every day. This waste is then dumped onto landfills and left to decompose. This waste causes a lot of environmental as well as health problems. The problem deepens further when the landfills are overfilled and there is no more space for any kind of waste. By producing electricity from solid municipal waste this problem can be solved, and it provides an alternative way to produce electricity.

The heat emitted from industry is recognized as a form of solid municipal waste, and now it has being recognized as a means of producing electricity. Efforts are being made to generate electricity from this waste source. There are physicists who are busy finding ways to produce electricity from this heat.

Another way to generate electricity from solid municipal waste is by the method of Pyrolysis. A chamber with no oxygen is used in this method. Organic solid municipal waste is decomposed in the chamber at a very high temperature. The waste undergoes the process of gasification as well. When both of these methods, pyrolysis and gasification, take place together they make the process of producing electricity very cost effective and efficient.

Mass burn technology is the most widespread ay of producing electricity from solid municipal waste. The process is very simple. All you need to do is to burn all the municipal waste. It is astonishing that the most developed countries where millions of tons of waste is created everyday fail to utilize this method of electricity production. Japan has been using this method for quite sometime and has been very successful in solving the waste management problems in many of its most populated areas. Regarding the emmissions from the burning of trash – this is no longer a problem as plants have advanced cleaning technologies which take out the pollutants from the gases emitted into the atmosphere.

There is plenty of garbage on this planet. In fact there is so much garbage that many developed countries are dumping their country’s waste in less developed countries in exchange for money, of course. They do this because their countries are extremely populated and they are unable to resolve the waste management issues. By using the abovementioned methods they can not only solve their waste management issues but also produce electricity in abundance. Waste to energy is undoubtebly one of the most important technologies of the future.

Municipal waste is one of the great problems of the modern age. Put simply, there is just way too much of it! It doesn’t help that so many of the materials we use nowadays biodegrade over a very long period of time. Landfills have been the answer to the municipal waste problem for decades now, as they are inexpensive and relatively simple to set up. Landfills, however, have a hugely negative impact on the environment. Harmful metals and chemical pollutants leach into the ground, and even get into the groundwater. In addition, landfills are a huge emitter of greenhouse gases, in particular methane. Anyone who works on a landfill will tell you that current consumption rates are unsustainable.

The time has come for big changes to be made. Recycling municipal waste is of great importance! Currently, new methods of recycling municipal waste are being implemented in several locations around the globe. A major one of them is called pyrolysis. With pyrolysis technology, the process involves the thermal decomposition of organic matter in a vacuum. Another method of environmentally friendly waste disposal is called gasification. It is a similar waste to energy technology to pyrolysis, except that a small amount of oxygen is present, unlike in pyrolysis that is fully done in a vacuum. Pyrolysis technology requires a source of heat for the process to take place, but gasification does not.

The use of pyrolysis technology is an old concept, but it is now being used in new ways, which help accelerate the landfill degradation process. Pyrolysis uses technologies of advanced thermal destruction, which require the heat to break the garbage down. However, this process does not burn the garbage; rather it turns it into products and by-products that are useful. Simply put, pyrolysis technology uses heat without oxygen to decompose organic materials chemically. It is actually similar to a toaster – using heat without direct flame – in order to have a faster break-down process.

‘Extreme pyrolysis’ process leave residue only in the form of carbon, and this is referred to as carbonization. Pyrolysis technology may also be utilized in order to create biomass liquid fuel out of plastics. This process is referred to as ‘flash pyrolysis’, which is done at temperatures of up to 500 degrees Celsius. This technique has a lot of versatility; therefore a wide range of industries use it for many different jobs. In landfills pyrolysis technology is extremely useful, because waste levels can be massively reduced, which, in turn, saves more land and storage space from being used for garbage. The only disadvantage of it is that it is a rather expensive process for many cities to use. Many big cities are still testing out whether pyrolysis is the right choice for them in terms of cost and efficiency.

Waste to energy technology provides a way to turn municipal solid waste into a source of energy to generate electricity. So, not only does it offer a solution to get rid of massive amounts of garbage we accumulate, but it can actually turn this garbage into something that can benefit the population immensely. Various waste to energy technologies exist today. There are chemical processes such as transesterification, used to produce biodiesel. There are also biochemical processes such as anaerobic digestion, resulting in chemical feedstocks, and fermentation, resulting in ethanol. Next, there are thermal processes such as pyrolysis, gasification, and incineration. All of these are processes of environmentally friendly waste disposal, since they produce no greenhouse gas or carbon emissions, which contribute to global warming, and are known to be harmful for the environment.

There is massive potential for growth in the industry of waste to energy technology, and the reason for this is simple. The world’s population is on a constant rise, and so is the amount of garbage our population produces. This factor makes this environmentally friendly waste disposal method a very attractive investment opportunity. There are various waste to energy technology plants operating already, and this technology is not too complicated for investors to understand. This means that it is easier to make wise decisions regarding your investment. The waste industry has always been and will always be in high demand, because without it, waste is a population health hazard. Environmentally friendly waste disposal will only become more popular, as more and more people become concerned with the environment. So, waste to energy technology is bound to take up a big chunk of the market share. What this also means is a big potential for high investment returns.

There is a brand new waste to energy technology process that originated in Ottawa, Canada. It is called plasma gasification, and most municipal waste manager don’t even know what it is yet. However, the president and CEO of Plasco Energy Group, Rod Bryden, is determined to get the word out. Plasma gasification is a process that produces steam, which, in turn, generates on-site electricity, and produces zero waste at the same time. Bryden says that there are so many benefits to plasma gasification that municipalities will be forced to learn more about it in the near future. First of all, this waste to energy technology produces no odor or emissions whatsoever, and it is completely quiet. Also, plasma gasification delivers power the electrical service system’s distribution portion, which takes the burden off the public grid, which is already heavily used. So, Plasco’s Coversion System facilities use household, municipal, and commercial waste to generate power that is completely green. They hope that other companies will follow their example.

Municipal solid waste generation can have various disadvantages if the right municipal solid waste management methods are not in place. Landfills are the most common of these and have been used for many years, but this municipal solid waste management method is not very effective. The waste in landfills can take decades or even centuries to completely break down, and while doing so, it can release toxic gases that are major contributors to environmental pollution. Landfills also tend to take up a lot of space, with millions of tons of waste generated every year by the U.S. alone.

Municipal solid waste recycling is one of the pros of municipal solid waste generation, because items like metal and plastic can be reused and removed before burning the waste. Municipal solid waste generation is a process that is ongoing, as every U.S. household comes up with at least one big garbage bag every week. This really adds up if municipal solid waste management methods are not efficient and just end up dumping the waste somewhere in a landfill. The Great Pacific Garbage Patch has very well demonstrated what can happen if waste is not disposed of properly. So, the municipal solid waste recycling programs are a small step, but they do add to some positives to the picture.

Municipal solid waste generation can be a good thing, especially when waste to energy programs are implemented and the millions of tons of waste in landfills are turned into energy to heat and power homes and offices. It is important to control these processes carefully, however, or there can still be some resulting environmental damage. Pollution control must be strictly followed in order to stop smoke or gases from being released. But if the waste to energy plants are built correctly, environmental damage should not occur in the area.

Municipal waste to energy plants practice municipal solid waste management very well, and they can use a number of methods to turn waste into a source of green renewable energy. Some of the waste to energy methods include gasification, incineration, anaerobic digestion, and pyrolysis. As various landfill in the United States are becoming overfilled, and with a number of them having closed already, the waste to energy programs are becoming more important than ever. Waste to energy programs are currently probably the best methods of municipal solid waste management, not only because they take the excess waste out of landfills and get rid of it in a non-polluting way, but it also becomes a source of renewable energy to generate much needed electricity for our homes.

Waste to energy plants use the technology of waste gasification to manage solid waste and obtain energy form it. There are various types of technologies used by waste to energy plants, but the technology of waste gasification is probably the most effective and efficient. Waste gasification plants have already demonstrated solid results. Municipal waste is considered to be a source of energy that is renewable because garbage will continue to be created on a regular basis. That is why this waste to energy technology is a very attractive one.

The way that gasification waste to energy plants work is that under anoxic conditions the trash is subjected to extreme heat to produce syngas, which is a blend of hydrogen and carbon monoxide, and this can be used as a source of fuel. The first step is to remove bulk metals, and the rest of the waste is shredded and conveyed to a gasification chamber with a temperature of 700 ºC. In there most of it volatilizes to a complex mixture of various gases, and then it rises to a plasma torch that has a temperature of 1200 ºC. The plasma breaks up this complex mixture into simple gases, like carbon monoxide, steam, hydrogen, sulfur and mercury. Then the clean up system removes the mercury and steam, and the syngas is directed to a combustion engine generator to create energy.

Waste gasification plants have various benefits, and almost no downside, although this waste to energy technology does require a lot of initial power. Waste to energy plants that use gasification of solid waste makes a lot of sense on various levels. Just like landfills, waste gasification plants can charge for solid waste disposal and the energy generated through waste gasification can sold for profit. So, from a financial point of view this type of waste to energy plants is a good investment opportunity. They use waste gasification methods that are environmentally friendly, which makes this source of energy a lot better than fossil fuels and oil.

When looking ahead into the future, waste gasification may prove to be one of the most important sources of energy. This renewable energy source can be locally utilized, which provides many advantages to local governments and the communities. As long as there are humans, there will always be waste to be dealt with, and the traditional methods of doing that just do not cut it anymore. Waste to energy technology can turn municipal solid waste into electricity for homes and businesses, which is a giant step forward from the traditional polluting landfills. Eliminating waste and cleaning up the earth can now also mean that fuel and energy may be generated, making this a win-win situation. Waste gasification plants may also be the perfect opportunity for investment for investors who are interested in renewable energy sources.

Municipal waste to renewable energy programs present a great way to turn discarded trash into a renewable source of energy, which can provide our homes with heat and electricity and be beneficial for the environment at the same time. When our waste is turned to energy, there is less space required in our landfills, which are already overfilled. Waste to renewable energy programs reduce the demand for harmful fossil fuels, because the energy received from these programs can be used instead. There are various municipal waste to energy programs currently running in the U.S., with the state of Kentucky alone generating enough energy from such programs to provide hundreds of thousands of homes with electricity every year.

There are two main ways in which waste to energy programs operate. Waste to energy facilities can burn the waste and use the released energy in order to create steam and heat, which is then converted to electricity. Most waste to energy facilities follow this procedure. The waste is sorted right away and recyclable materials are excluded. Even plastics and tires can be turned into energy, and other items like metal cans are put aside. Then the materials chosen for the burning will be put into the incinerator, and the energy released is captured in the form of steam, which creates electricity. The second way in which waste to energy programs operate is to collect methane gas, which the waste releases when it decomposes, but this is not as common.

Waste to energy plants on a commercial scale operate in the U.S., and they range in size from 200 to about 3,000 tons a day. The facility’s processing capacity is a function of various technical considerations, such as the facility’s capital and operating cost and the amount of waste left to be processed after recycling. They also depend on their long-term planning goals, such as domestic alternative energy source benefits, carbon footprint reduction, and stability of disposal costs.

For every converted ton of municipal waste, we can save a barrel of oil or 250 kilograms of coal. Every year in the U.S. there is almost 300 million tons of garbage sent to landfills. If all this waste was converted to energy instead, our dependence on oil could be reduced by 3-4 percent. This is equivalent to thousands of tons of coal and hundreds of thousands oil barrels.

Municipal waste to renewable energy programs also benefit the local economy directly and indirectly. Construction workers hired from the local area by the waste to energy facilities would receive paychecks amounting to millions of dollar annually. The indirect benefits of this are in the millions for the local area. Various goods and services that are construction-related would also be purchased locally, which would, in turn, boost the economy.

There are various types of waste to energy technologies, including pyrolysis, gasification, combustion, esterification, fermentation, and anaerobic digestion. Some of these waste to energy technologies use chemical or biochemical processing and others use thermal processing. Municipal waste to energy technology can meet households energy needs, while waste-created biofuels can power automobiles.

Pyrolysis and gasification are probably the most cost-effective modern waste to energy technologies. To further maximize cost-effectiveness, they can be performed together. Pyrolysis requires an external source of heat, which can be provided by the process of gasification. This combination of processes is self-sustaining, which reduces the costs, therefore making both of them increasingly cost-effective

Anaerobic digestion is another currently available type of waste to energy technology. In this method the waste is placed into digesters specially constructed for this purpose, where oxygen cannot get through. In this way the waste can break down quicker, which releases methane and other greenhouse gases. It is possible for heat to be created in this process because of extensive microbial activity in decomposing biomass.

Fermentation is another waste to energy technology, which can create ethanol out of biomass, using organic or cellulosic material. During the process of fermentation, the sugar found in the waste gets changed to alcohol and carbon dioxide, much like in the wine-making process. Fermentation normally occurs when there is no air present.

Another kind of waste to energy technology is something called esterification. Biodiesel is the result of this process. The feedstock used will determine esterification’s cost-effectiveness. Other factors that contribute to the effectiveness of esterification include the amount of oil in the feedstocks, the transportation distance, and various others.

Waste to energy technologies have been declared by the Environmental Protection Agency as having the least impact on the environment out almost all energy sources. Mature technology and strict regulations helped waste to energy plants be efficient and green at the same time. Every year about 12-15 percent of America’s solid waste is turned into electricity, which amounts to over 100,000 tons daily and provides 2.8 million homes with electricity.

So, if the process is effective then why is only a fraction of the trash burned? Well, this comes down to economics. In some locations some waste to energy technologies make more sense than others. Hydro, nuclear power, and coal are still cheaper energy generation methods. But waste to energy technology has many other benefits like landfill reduction. Also, waste to energy technologies do not produce greenhouse gases which are then released into the atmosphere, and they help reduce usage of fuels by reducing transportation of waste for long distance.

The great pacific garbage patch actually consists of two large areas – the eastern and the western patches. The eastern patch is between California and Hawaii and it is over twice the size of Texas alone. The western patch is located between Hawaii and Japan. These Pacific Ocean garbage patches collect currents that carry debris and waste from all over the globe. When the currents reach the great pacific garbage patch, they deposit the garbage they have accumulated. Because neither fishers nor tourists ever visit the area due to the lack of marine life, most people are not even aware of the existence of the pacific ocean garbage patches.

Some people have called it “the plastic island”, and according to them, it poses an enormous threat to the environment of the whole planet. However, others claim that it actually has great potential for alternative energy generation. There are waste to energy programs, which may turn the great pacific garbage patch into electricity and heat for homes and offices. Waste to energy power plants convert solid waste (even plastics) into energy. These waste to energy programs create a win-win situation in the case of the pacific ocean garbage patches. The trash would be taken out of the ocean, leaving the marine life and the birds unaffected by toxins, and energy can be generated by non-polluting methods.

These Pacific Ocean garbage patches have created an amazing opportunity for green energy. There are shortages of energy all over the world and fossil fuels are damaging the environment more and more, so something has to be done. Using the great pacific garbage patch for a plant under a waste to energy project could turn an environmental threat into an alternative energy source.

Waste to energy programs are a great way to turn pollution into energy. Such technology can prevent 40 million metric tons of emissions of greenhouse gas (in carbon dioxide equivalent form) from being released into the atmosphere every year. Waste to energy programs also prevent nearly 2.6 million tons of volatile organic compounds and 24,000 tons of nitrogen oxides from being released into the atmosphere.

The current way to get rid of garbage is land disposal, which causes the release of methane, which is a powerful greenhouse gas, as this garbage decomposes. Waste to energy facilities are a clean alternative to this and can also produce electricity. Their main benefit, of course, is decreasing reliance on power plants that result in carbon dioxide emissions when oil and coal are burned, which result in one of the worst kinds of greenhouse gas emissions into the atmosphere. Waste to energy plants do not release methane into the atmosphere, which would otherwise occur when the trash decomposes. They also avoid the release of CO2, which is usually released when generating electricity using fossil fuels.
