Waste Recycling & Processing Plant – Plant Operation

 

The following is a brief description of the process of waste travel through our plant. Major equipment items are

shown in bold type. 

 

  1. Waste-filled trucks enter the plant by stopping at the Weigh-Station.  The trucks containing waste entering the plant via the commercial waste management companies have reader cards attached to them which allows the computer system to read each truck, weigh and document the waste entering the plant from each truck and each commercial waste management vendor. The person working in the weigh-station has only to manage the commercial trucks            entry and exit, and to handle waste coming into the plant via private citizens.

    2. Next the waste delivery truck enters the Tipping Room, where the truck empties its’ waste onto the floor of the tipping room. The truck then leaves our 

        facility, first passing through our Truck-Wash, where we ensure that nothing from our plant is tracked onto the adjacent roadway.

 

        Note:

        Medical & Governmentally sensitive materials are not set on the tipping room floor. Instead these sensitive materials are sent directly into the main

        combustion chamber via a “side” mounted crane, which dumps into a separate entry into the main combustion chamber. Officials are able to witness the

        placement of these sensitive materials into the main combustion chamber.

 

        Liquid waste, such as unused pesticides & herbicides enter the main chamber through a separate system where these liquids are atomized as they enter the

        chamber.

   3. Once the waste has landed on the tipping room floor, it is separated.  Separating Waste is accomplished by hand and with the use of small “bobcat” type

       loader.  Waste is separated and those products available for recycling, such as metals, glass, tires, textiles, batteries & computer components are removed.

       These products are transferred to the appropriated facility for recycling. We like to keep tires as our system can use them to help regulate main combustion

        chamber temperatures.)

 

    4. All remaining waste pass through a Trommel where they are partially dried and separated by particle size.

 

    5. Next, the waste is loaded into a Shredder, where all materials are shredded into small sized portions.  (Hand-size.) Waste passing through the shredder also

        give off the excess water often contained in the waste.  This water is sent to our Wastewater Filtration System where it is cleared of contaminants and

        either used within our plant or sent for agricultural usage.  (This water is not suitable for drinking but is suitable for agricultural use.)

 

    6. After passing through the shredder the waste enters our second Trommel, where it is further mixed and dried as it passes towards the main combustion

        chamber. Hot air from within the plant is used to help lower the moisture content of the waste.

 

    7. Waste then enters the main Thermal Conversion Chamber, (TCC).  The main thermal conversion chamber is a multi-patented system.  

        Development of this chamber has advance over 40 years of usage and the evolution of these years’ experience, and use of computer aided technology, is                  now a part of our state-of-the-art chamber.

 

        The main thermal conversion chamber achieves temperatures in excess of 2,400 degrees F. (1,315 C) The chamber also is designed to create a cyclone effect,

        which holds the waste within the high temperature zone until it has reach complete particle separation. For particle separation to be complete the

        critical elements needed are “Time, Temperature & Turbulence”. Our Olivine style chamber achieves more complete particle separation through our use of

        the cyclone effect, and a ram system which continually agitates the lower portion of the chamber where heavier materials will tend to land. This cyclone

        effect also makes it difficult for any particle not fully treated to leave the main chamber with the flue-gases.

 

        The boiler is NOT contained within the main conversion chamber.  This is a major difference and improvement over other systems.  Typically, the boiler is

        contained inside the combustion chamber, where flue-gases pas directly through the boiler tubes.  These flue-gases are heavy in incinerated and partially

        incinerated particles.  These particles clog, pit and deteriorate the boiler, causing extremely high maintenance issues, and a lessen life expectancy of the

        boiler. This configuration also causes plant shutdowns to clear, clean and repair the boiler.

 

        We have our boiler in a separate the from the main thermal conversion chamber.

    8. The flue-gases exiting the main chamber are sent to the Particle-Separator-Boiler, a multi-patented system, where the flue-gases continue in a cyclonic 

         action  and boiler tubes are set in such a way as to minimize the detrimental effects of particle filled flue-gases passing through the boiler tubes. As in a

         cyclone, flue-gas particles are forced to the outside diameter of our particle-separated-boiler, leaving mostly clear flue-gases to pass through the boiler

         tubes.

 

   9. The boiler and Turbine-Generator Systems work the same as most steam power energy producing plants.  The boiler is of Lucia Engineering, Inc. design and             we stay to experienced-proven manufacturers for the turbine-generators.  (Elliot, GE & Siemens, as examples.)

 

       Depending on the waste being handled, there may be multiple particle-separator-boiler and particle-separator units being used to both generate steam and           to reduce the number of gas-borne particles within the flue-gases prior to sending these gases to the MS Scrubber.

 

 10. We use Air-Cooled Condensers in our steam system as these require much less water usage than the conventional cooling tower systems.  Rainwater is           

       collected across our entire plant area for use in our steam system and is used to help supplement water usage.  Storage and filtration systems are included   

       within our plant.

 

 11. Electrical power generated within our plant is sent to our Transfer-Station where it is adjusted as required to connect into the existing power distribution g

        grid.

 

 12. After existing the particle-separators the flue gases enter the MS Scrubber.  The MS Scrubber is a multi-patented system owned and manufactured by

        Envirocare International. Gases exiting the Scrubber exceed all EPA requirements anywhere in the World.  These gases are clear, colorless and odorless. The

        MS Scrubber is a Wet-Scrubber system, which far exceed the Baghouse type system currently being used by our competitors. Envirocare’s scrubber is the

        only scrubber we incorporate into our plants, as this scrubber represents the current Best-Available-Technology, system. 

 

 13. Ashes are accumulated in the main combustion chamber, the particle-Separator-boiler and at the MS Scrubber.  These ashes are non-toxic and are further

        recycled and used in the making of asphalt bases and paving, precast concrete and masonry units, fire-brick units, and other post-incineration products.

 

        These ash-based products can be added as a part of the plant for added revenue generating businesses, or they may be sent to local established business

        that would benefit from the ash we can provide.

 

        No part of any waste entering our plant is sent back to the landfill.

 

 14. A fully functional, Computer-Controlled operations and system monitoring building is set within the main building, where all aspects of the plan are

        monitored.  We also monitor the plant from our offices here in Washington.

 

 15. We operate or critical equipment, the main combustion chamber, particle-separator-boiler, turbine-generator system and scrubber within a building

        structure, as these systems utilize materials that can be weather sensitive.  Plus, we feel the buildings pay for themselves over time with the savings in

        required maintenance.  And lastly, with the landscaping we provide, the entire plant look pleasing to the eye.

 

 16. Available Plant Sizes:

        Our minimum plant size is 250 TPD and producing 6 MW of electrical power.

        Our plan sizes are scalable, in 250 TPD increments. Plant sizes range from 250, 500, 750, 1,000, 1250, 1,500, 2,000 TPD etc.

 

        Our plants are segmental in design and construction which allows us to easily modify an existing plant for a higher production and it also allows us to shut

        any one line down for maintenance without totally shutting down the plant.

 

 17. We supply a “turn-key” project.  That is a plant that is fully operational and operating. Everything needed to operate and run the plant is provided. Plus, we   

        manage the plant for 3 to 5 years, to ensure that the plant produces as promised and to ensure that the people taking over the plant at our departure fully

        understand how to operate and maintain the plant.
