Power Plants

 

Recognizing the demand for the generation of electrical power and the need for the disposal of vast quantities of municipal and biological solid waste, as well as elimination of raw sewage, World Safety Inc. is committed to bring turnkey municipal and biological liquid and solid waste resource recovery power plants to Central America. World Safety Inc. and an association of municipalities of the providence of Chiriqui, Panama plan to build a waste to energy power plant and use the profits from the sale of electricity to fund children programs in The Providence of Chiriqui.

World Safety Inc. has assembled a group of experienced and seasoned executives, engineers and consultants to complete the municipal and biological solid waste resource recovery power plant projects in Central America. This group is dedicated and knowledgeable in all areas associated with these projects including refuse handling; collection and transportation; project management, contract negotiations and administration; cost and scheduling; and procurement and financial administration. The picture above right is of landfill in the Providence of Chiriqui, Costa Rica, which will be cleaned up.

There is a need in Central America to eliminate growing mounds of municipal and biological solid waste, as well as the need to generate electricity. Landfill space is running out and there is the environmental concern over the health implications from many existing landfills around Central America. In the developing countries of Central America there is a growing need for electrical power that is required for industrial growth in order to raise the living standards of their residents. Our resource recovery power plants provide this much needed energy while delivering important benefits of reducing the municipal and biological solid waste as well as creating numerous quality employment opportunities.

 

 

Sewage waste continues to be a problem in Central America as well. Today over 80% of the sewage waste throughout Central America is dumped right into the rivers. Sewage treatment is inadequate. The good news is governments like Panama recognize the problem and are working on ways to eliminate the problem from their country forever.


 

 

System Description

 The system is a 36 mega watt cogeneration plant that can use a variety of wastes including MSW (Municipal Solid Waste). The system is designed for a regional approach that addresses the needs of Chririqui Providece, Panama. When using MSW the system recycles approximately 18% of the waste and produces a compost able material (cellulosics) from approximately 82% of the waste, which is used for energy production for the plant supplying steam and electricity with an excess of both sold to to the electric utility.

 

 Various advantages of the MSW portion of the plant are:

 
  • Reduces landfill capacity by approximately 100%
  • Eliminates curbside recycling
  • Recycles glass into different colors for greater returns
  • Recycles ferrous metals and aluminum
  • Recycles high and low density plastics
  • Uses sanitary classification technology for sanitary separation and handling
  • Automates handling, separation, and deposit of recyclables and byproducts of the cellulosics
  • Reduces heavy metal and dioxin concentration before combustion
  • Recycles flue gas for compliance with air quality standards
  • Allows both truck and personal dumping access
  • Separates the dumping area from the processing area
  • Produces and filters its own water
  • Normally provides returns on investment at a minimum of 35%
  • Operational for periods of 10 to 35 years (Project designed life cycle)
  • Waste loads from 1200 tons/day and expandable
  • Allows additional waste types such a tires, construction debris, agricultural wastes, forestry wastes, and a variety of industrial wastes
  • Produces all the plant’s own energy needs
  • Produces an excess of marketable forms of energy such as heat, electricity, and fuel pellets
  • Utilizes a well proven and simple design for combustion
  • Complies with or is well below the most stringent environmental standards for emissions

 

The plant also has the capability to allow a number of other types of wastes to be processed with different shapes and moisture content. These other shapes are either separated and manipulated for various other markets or can be mixed after a size reduction if needed, along with MSW primarily for energy production. A number of wastes from agriculture, forestry, paper mills, and other industries that were prior land filled can now be utilized by way of a unique machine in the plant that reduces the moisture content and produces a particle of an optimum size for combustion or marketing. Because each type of waste can be separately handled and processed, it/they can be optimized for different markets. Normally, all the wastes are separated after processing into separate self-unloading containers so they can be extracted and possibly mixed for the best market at any time to maintain a better return in capital to the plant. If perhaps an energy issue is prominent then the additional wastes can be routed around the MSW portion of the plant and converted directly into fuel particles.

 

Various advantages of the extra waste handling capability are:

  • ·        Optimal compaction and consistent sizing of fuel and marketable items

  • ·        Increased capacity in shipping, approximately 25%

  •          Reduction of shipping costs by the reduction of weight (H20)

  • ·        Longer storage life because of reduced moisture

  • ·        Mixtures of marketable items

  • ·        Capability to address previously unused wastes of high moisture content

  •          More efficient moisture reduction technology

 

 

 

The extra capability to handle high moisture content wastes is a boon to developing countries, a large number of which have the same agricultural industries such as coffee, bananas, pineapple, rice, etc., and whereas there is usually more than enough waste discarded by those industries to provide energy to process or dry their products for market.
