Stationary sources Waste incineration Steel industry Recycling plants Energy production Municipal solid waste, clinical waste, hazardous waste, sewage sludge Steel mills, sintering plants, hot-strip mills Non-ferrous metals (melting, foundry Al, Cu, Ptx, Zn, Sn) Fossil fuel power plants, wood combustion, landfill gas... 

In the United States about 3 percent of all electricity produced comes from renewable sources of this a little more than half comes from biomass. Most biomass energy generation comes from the lumber and paper industries from their conversion of mill residues to in-house energy. Municipal solid waste also is an important fuel for electricity production approximately 16 percent ot all municipal solid waste is disposed of by combustion. Converting industrial and municipal waste into bioenergy also decreases the necessity for landfdl space. 

The use of municipal solid waste as a source of energy fills a special need by partially ehminating nrban waste in an enviromnentally acceptable maimer while at the same time prodncing usable energy. 

Wave power, tidal power, municipal solid waste, gas from animal wastes (biogas), landfill, peat energy and ocean thermal energy conversion (OTEC) are the other renewable energy sources (RES). Water energy sources are hydropower, tidal and wave technologies. 

The plasma energy recycle and conversion (PERC) process is an indirectly heated ex situ thermal recycling and conversion technology. According to the vendor, it treats hazardous waste, mixed radioactive waste, medical waste, municipal solid waste, radioactive waste, environmental restoration wastes, and incinerator ash in gaseous, hquid, slurry, or solid form. The technology uses an induction-coupled plasma (ICP) torch as its heat source coupled to a reaction chamber system to destroy hazardous materials. 

Fig. 6. An integrated approach to the management of municipal solid waste (MSW), advocated by the U.S. EPA, that links source segregation, recycling, waste-to-energy (WTE), and landfilling in a single system. Source segregation refers to the separation of compostable and recyclable components from the balance of the trash at the point where MSW is collected. In source reduction (not shown), another action to reduce waste to landfills, changes are made in...

Includes energy from wood and wood-derived fuels municipal solid waste from biogenic sources, landfill gas, sludge waste, agricultural byproducts and other biomass (through 2000, also includes non-renewable waste such as municipal solid waste from non-biogenic sources, and tire-derived fuels) and fuel ethanol and biodiesel consumption, plus losses and co-products from the production of fuel ethanol and biodiesel.

Urban refuse or municipal solid waste is produced at a rate of about 11 kg (5 lb) per person per day, and contains both organic as well as nonorganic materials. Combustion of organic waste represents a supplemental source of supply of energy. Table 4.9 lists the HHV for typical wastes. If you watch calories, Table 4.10 shows the calories in various foods. Table 4.11 indicates some heating values of typical coals. 

Municipal solid waste (MSW) is usually incinerated at a central disposal facility. Central disposal facilities are often used for energy generation. While these facilities have largely been popular in Europe, more central disposal facilities are appearing in the United States since the cost and availability of traditional energy sources are no longer reliable. 

The biomass-derived fuels including not only wood waste, but also peat wood, wood sludge, liquors, railroad ties, pitch, municipal solid waste, straw, landfill gases, fish oils, and other waste products, are important sources of energy in many parts of the world. It is also an increasingly scarce source as more and more forests worldwide are used for agriculture. It is difficult to envision the...
