GFS Municipal Solid Waste Process
Municipal Solid Waste is a major problem for all cities but it is also a potentially valuable energy resource. Currently, most MSW is land filled or sent to an incinerator for burning. Both the landfill and incinerator solutions cause significant environmental problems such as air pollution, land pollution and contamination as well as being costly to set up and maintain. Significant amounts of toxic materials are buried under ground including the waste generated from incineration. The public is also very aware of the global warming and CO 2 emission problems.
New generation waste-to-energy systems for dealing with MSW are now being taken seriously by the public and the regulatory authorities responsible for the environment. Currently, most countries are considering replacements for incineration and landfill. They are looking at new technologies like gasification, plasma gasification waste-to-energy and pyrolysis technologies. But, to date, they all have inherent drawbacks.
The M-2500MW thermal decomposition system overcomes these problems and can be tailor made to match individual requirements. Some of the advantages of the system are:
- Very few, if any, hydrocarbons need to go to landfill.
- These can be eliminated with additional technology provided by GFS.
- No Emissions.
- Low capital expenditure – very quick payback periods.
- Modular construction makes it easy to expand or relocate.
- The byproducts of the operation are carbon and fuel-oil – both valuable commodities.
- Simple to operate by semi-skilled personnel.
- Full warrantee and support service by the manufacturer.
- Complete “no mess” turnkey plant layout and equipment if required.
MSW is a mixed waste containing various composites and is difficult to treat by traditional methods. Conventional pyrolysis systems are inherently dangerous due to the possibility of hydrogen buildup and they are also unable to efficiently treat a mixed feedstock.
Typical methods to gasify municipal waste with its inherent problems of air pollution and fly ash residue require large and very expensive plant to convert the hydrocarbons to fuel-gas. This gas is then used to run a gas turbine to generate electricity. This is a large and expensive operation.
The M-2500MW offers the ideal solution to deal with municipal waste as it combines thermal decomposition with gasification and does not convert the hydrocarbons to fuel-gas only.
The system for MSW produces fuel-oil as the main by-product and a controlled amount of biogas which is used to heat the reaction chambers. Carbon is the other byproduct of the system and the fuel-oil and carbon are both in demand on the open market. There is no fly ash to contend with and also no air pollution.
A M-2500MW plant for municipal waste processing can be tailor made to the requirements of the customer as they are modular and have a small footprint. A small single reactor plant will process 50 ton of mixed waste per 24-hour day and it is a very commercially viable plant. It is easy to operate by semi-skilled personnel and it will pay for itself in a short time frame with the sale of the byproducts. As we know typical land fill solutions have serious limitations with pollution issues, environmental impacts and are very costly to operate and maintain.
This small and relatively inexpensive plant makes it ideal for smaller communities or for the installation of a number of local plants for larger communities to reduce transport.
