Front End Recycling




We tend to prefer projects which remove recyclable materials, and non recyclable materials. We can’t gasify stone and glass, and we should recycle aluminum cans, etc.

Front End Recycling, Single Stream.

Waste Transfer can be clean





Transfer to Waste Processing can be direct or by trans shipment. Baling systems can produce wrapped waste with NO odor and NO negative image.

Fully enclosed waste transfer

Visually neutral.






Bales weigh approximately 3,500 pounds each. Compressed approximately 14:1 ratio. Can be stacked deeply, and held in high temperatures without problems

Refuse Derived Fuel






Municipal solid waste (MSW) is processed into Refuse Derived Fuel (RDF) in a MRF – i.e., in a Material Recycling Facility The RDF can be gasified in an Biosphere Gasifier The RDF can also be mixed with 82% moisture content “belt pressed” Municipal sewage sludge and gasified in an Biosphere Gasifier

Proven Commercial Performance






Two units (45,000,000 Btu x 2) have been running continuously for 27 years. The machine has lasted longer than most of the ten forestry product companies who installed units. Reliable, robust, solid and proven fluidized bed updraft gasification that can project finance.

Firing of Steam Turbine








Biomass is gasified in separate units built alongside of steam turbine. o o Gasifiers 2,000 F ± 200 F products of combustion are ducted to Heat Exchangers which drive steam into the Turbine. Products of combustion from Heat Exchanger goes into our special bag houses. Biomass moisture content up to 65% is “OK” for our gasifiers.

Significant Features, 1
  





Four air sources: Underfire air gasifies biomass in the 1st stage Overfire air preheats 1st stage producer gas to ensure ignition in the 2nd stage Primary combustion air ignites the preheated producer gas at the bottom of the 2nd stage Secondary combustion air completes combustion of producer gas in the 2nd stage

Significant Features, 2

  

Very large 1st stage grate area
Hence grate temperature ≤ 1,200oF Hence essentially zero slag Ash can be reclaimed as valuable products





Very low underfire air flow
(only need sufficient air to gasify biomass) Hence very low particulate elutriation off pile

Significant Features, 3








The Biosphere Gasifier can burn biomass with moisture contents up to 65% (wet basis) and ash contents up to 35% 5:1 turndown ratio is standard; 9:1 is not uncommon 15 second response time to step change in Btu Demand signal Abort valve permits rapid dumping of products of combustion in an emergency

Refuse Derived Fuel








Municipal solid waste (MSW) is processed into Refuse Derived Fuel (RDF) in a MRF – i.e., in a Material Recycling Facility The RDF can be gasified in an Biosphere Gasifier The RDF can also be mixed with 82% moisture content “belt pressed” Municipal sewage sludge and gasified in an Biosphere Gasifier WILL OR WON’T, VERSUS, CAN’T!

Physical Plant Construction

CONSTRUCTION




Estimated direct workforce will be 35 to 40 men for approximately fourteen months. Additional jobs will likely be in transportation and supply.

Construction Major Trades










Heavy Equipment operators Electrical, Major and sub-systems Machinists, Welders and fitters Power Equipment, Cranes, Concrete Refractory

Environmental Compliance

KYOTO PROTOCOL TO THE UNITED NATIONS FRAMEWORK CONVENTION; CLIMATE CHANGE




Reducing the greenhouse gas effects of the combustion of fossil fuels is exactly the value produced by a biomass and refuse derived fuel based power plant. ZERO “new” CO2 production cycle.

Biosphere Gasifier
 







1st Stage: gentle updraft gasification on very large grate 2nd Stage: vigorous, double vortex, cyclonic combustion Emissions (untreated): CO < 1 ppm, NOx< 15 ppm, particulate < 100 mg/Nm3 (< 0.125 lb/106 Btu; < 0.04 gr/dscf) Emissions listed are prior to treatment, Bag House @ PM2.5 and Wet Tubular Electrostatic Precipitators are planned for projects. Units in continuous operation for 25+ years

Significant Features, 4






Staged combustion permits operating with excess air levels as low as 15% The lime kiln test unit burned 55% moisture content hog fuel and supplied 2,200oF flue gas to the kiln @  = 15% Staged combustion and low temperatures (due to wet fuels) combine to produce virtually zero thermal NOx

Significant Features, 5
 





Dioxins and Furans Destroyed, viz., Chlorine can react with cellulose to form dioxins and furans in the 1st stage However, these gases are destroyed in the 2nd stage with its 1,800oF plus brick walls No black waterwalls are present to chill and lock in - dioxins or furans in the 2nd stage

Dioxins & Furans M.A.C.T.




M.A.C.T. is maximum available control technology. (Also sometimes known as B.A.C.T. or Best Available Control Technology). While we should not have any issue with this on our gasification, we include special bag houses that would automatically catch any dioxins or furans at 40% below the current A7 Ontario Standards. Very, very clean.

Natural Exposure is Forest Fire

SWEDISH EXPERIENCE


29 Waste to Energy plants operating at this time. GUESS: What is their total output of dioxins, all 29 plants, annually?



M.A.C.T.



The Idaho National Laboratory has come up with a way to insert a “re-burn” chamber for NOx on the exit ducting of our gasification unit. Given the low proteins in municipal waste product and very low thermal NOx this would be a very conservative move that we would do more for “PR” than any need –but this is a test we are interested in and will pursue.

Agricultural Wastes






With a grate temperature of 1,200 F, potassium (potash) and sodium (soda) in agricultural and animal waste do not vaporize to form alkali deposits on boiler tubes Potassium vaporizes at 1,400oF and sodium vaporizes at 1,616oF The potash and soda remain in the 1st stage, from which they are removed by the built-in ash removal system and sold to farmers depending on what else is present

What would we like?








Letter of intent for projects from the Government, waiver of import duties. Waste contracts for all of the Various cities waste at $40+/ton; PPA of $0.099 PPP of some kind on the recycling portion of the project. Political support in complying with all of the appropriate requirements.

Letter of Commitment question, funding:
    

The short answer is "YES", we can obtain commitment letters "subject to", but, make no mistake, we would not take this to our funding groups at this juncture because we have not done ANY of our homework. We don't even have the MOU signed and returned.



 

1. We have no waste composition or proximate or ultimate analysis on which to base our engineering opinions to our own funders and partners. We have no assurances that the waste which would be characterized will be maintained within normal variance. We have no moisture content and inert contents review done. We have had no discussions on the disposal of inerts which will prove to be critical to this project in a "no landfills" mandate. 2. We have no letters of intent from any of the Cities we are going to be working with to provide us with take or pay contracts which underpin our deals both on the Waste Off take contracts and on the Power Purchase agreement. We have no economic basis for even basic deal economic evaluation. No tipping fees outline with escalators, no PPA rates and acceptance terms, no nothing! 3. We have no site or location selected with a logistics and permitting study, even a basic one, done. 4. We have no property tax deal, no governmental guarantee on the waste contracts and the land purchase and no waiver of import duties in place.
