The Hoskinson Group, LLC
Jacksonville,, United States

The Hoskinson Group is led by Gordon Hoskinson, the world-renowned expert and leading innovator in Waste to Energy (WtE) production through his proprietary gasification and combustion process that meets or exceeds applicable environmental standards today.  He is also a World War II veteran.

The Hoskinson design is the Renewable Energy Solution that does not consume natural resources and uses only garbage and other waste to produce up to 10 MW of electricity per 150 to 175-ton per day installation.

Mr. Hoskinson is considered the world’s foremost expert on modular pyrolysis and gasification for the last 45 years and is widely recognized as the most important inventor in this entire industry.  The U.S. EPA recognizes his work in the late 1950’s and referred to him in the late 1970‘s as the “...Father of the controlled air smokeless process based on the principals of after-burning.”

Mr. Hoskinson is and always has been “hands on” in all stages of development of each generation of his machines and has started several companies in this field including the current business located in Florida.

Mr. Hoskinson holds numerous patents in the field and is known for inventing the Hoskinson Pyrolytic Gasification technology for use in waste disposal; Pyrolysis is the proven technology breaking down of matter into char, tars, oil and hydrocarbon gas in the absence of oxygen.  While Hoskinson’s Pyrolitic portion of the process is oxygen-starved, it still maintains many of the benefits of complete pyrolysis.  

In 1954, Gordon Hoskinson was building heat exchangers in New Hyde Park, New York and had a lot of trash from the operation and large heat bills heating the plant. He built his first WtE unit called the “Shop Heater”. The trash from the manufacturing operation was ample to heat the plant. As suppliers of parts for his operation saw the results they wanted him to build one for them.

He started the true modern revolution in WtE through the world where small, efficient combustion units became a reality overnight.

Since 1958, Gordon has been making and delivering waste combustion units of multiple sizes and for various uses.  His older component designs have been copied by at least 100 companies worldwide and in many cases, are still in use.  He designed the controlled air and after burner combination, which was later called “Pyrolytic Gasification” by the Engineering Society of the United States.

Fly ash and dirt were the bane of the old incinerator design that caused a bad reputation for New York apartment buildings. It became a national joke in the 60’s.  The Hoskinson design was a totally new design that eliminated this problem and gained immediate acceptance worldwide.

A demonstration in London at the Quaglino Hotel in the 60’s to the press corp of London led to more than 1000 machines being built by Middon Industries of Walterhampton, England the first year!

Throughout the next 3 decades, Gordon Hoskinson manufactured and sold thousands of units to many of the Fortune 500 Companies, the White House, other federal agencies, nearly all international airports, and most of the major medical centers in North America.

After his experience in Korea, Barbados and other countries in the 90’s, he was retained as a consultant by a firm in Indiana to develop the next generation medical waste modular combustor based on his decades- long proven experience and technology.

Two years of intense research was completed, and from that research, major innovations have been added to our latest version of Hoskinson’s successful designs legacy.

it just makes sense to use the waste and garbage that our society creates and turn it into a responsible and clean source of renewable energy.

This is the ultimate Renewable Energy Solution available today. Our Waste-to-Energy power plant is designed to convert many types of waste into a source of stable and continuous electricity for homes and businesses. And in the process, our design also meets or exceeds all applicable environmental requirements without the use of extensive and expensive anti-pollution control equipment.

Whether its disposing of Municipal Solid Waste, Industrial Waste, or Medical Waste, The Hoskinson Group has the right solution tailored to meet your requirements and we have the history to prove it.

Each Plant uses our proven and proprietary pyrolytic gasification process which reaches temperatures of nearly 2,000°F that very efficiently disposes of waste, pathogens, and other pollutants. Operating at these temperatures very efficiently converts even high-humidity content waste into power at up to 6 MW per 150-tons per day of waste. Higher BTU content waste may produce up to 10 MW per unit.

The Plant uses virtually no external fossil fuel, produces no discernible pollution, and uses proven and innovative Hoskinson technology developed by Gordon Hoskinson over the last 45 years, which makes it is easier to maintain and operate. Staying true to a “keep it simple” philosophy also reduces the Total Cost of Ownership and provides for the potential to operate each plant at a profit.

We can increase the waste throughput using our unique scalable design to consume up to 800 tons of waste per day and produce a corresponding increase in electricity production by co-locating up to four of our gasification and combustion units into one Facility. This multi-unit deployment strategy also provides for a rotational preventative maintenance schedule for each unit without shutting down all operations. Additionally, geographically distributing our Waste-to-Energy Facilities around larger communities results in more efficient waste collection operations that can consume thousands of tons of waste per day.

Our modular “bolt-together” design keeps on-site fabrication to an absolute minimum which increases the quality and speed of the installation. Full Facility operations can be initiated within 12 months or so from the time of purchase. Download our latest brochure here for a summary of features.

The Hoskinson Group has the experience and knowledge to solve the problem of waste that many cities face today.

In many cases, the electricity-generating component of the Facility provides a financial bonus to the dire need of removing the waste and usually provides a profit center for the community or private enterprise. In these times of tight budgets, this can help bridge the gap to pay for essential community services.

Most landfills operate as they have over the last 50 years where trucks arrive to the landfill, are weighed, and then the waste is dumped into the open landfill. The waste is compacted and covered with dirt or other type of fill material. The result is valuable fuel buried forever and methane gas (a major source of green house gases) spewing into the atmosphere for decades.

Hoskinson’s modern Waste-to-Energy (WtE) operations change this status quo dramatically where the waste can be used as fuel to generate clean and responsible power for thousands of homes and businesses for generations to come.

This modern and proven process begins after the garbage truck is weighed. The contents are dumped into the recycling operations section of the WtE Facility, where skid steers remove large or hazardous items for recycling and proper disposal.

The balance of the material is then shredded and processed through a combination of automated recycling machinery and manual labor stationed along a series of conveyor belts. This part of the process removes much of the metals, glass, and other non-combustible materials inappropriate for introduction into the combustion chamber of the WtE plant.

Recycled material is then packaged and prepared for shipment out of the Facility at regular intervals.

The remaining waste is moved by front-end loaders to a staging area inside the building where it is prepared for the WtE plant. Front-end loaders continuously load hydraulically operated ram feeder that introduces the waste into the main primary Pyrolytic Gasification chamber.

This proprietary Pyrolytic Gasification and oxidation process developed by Hoskinson nearly 40 years ago and perfected over the same time, provides a near complete level of combustion with virtually no fly ash.

The waste is gasified in the primary chamber into a synthetic gas or “syngas” that contains a highly combustible mixture of primarily CO, H2 and other hydrocarbons. The waste continuously moves to the rear of the primary chamber until it is consumed. The primary chamber operates in an oxygen-starved or substoichiometic environment that minimizes oxidation of the syngas at this point.

The syngas then moves from the top of the primary chamber to the secondary chamber where an additional regulated amount of air is added to the syngas flow. While the syngas could be cleaned at this point and introduced into conventional combustion engines, the syngas is oxidized in the secondary chamber more efficiently where temperatures may approach 2,300°F. This is where additional thermal oxidation reactions occur, now with trace amounts of super heated steam present in the waste. This is an extremely exothermic reaction that generates a tremendous amount of heat which is capture by a Heat Recovery Steam Generator (HRSG).

The HRSG generates superheated steam under moderate pressures and temperatures. This steam is regulated and introduced into the turbine / generator set which spins and creates the electric current.

The exhaust steam is condensed and reintroduced into the HRSG for reheating. The condenser, generator, and other parts of the plant can be air-cooled, which substantially reduces the amount of water needed by the Facility to operate.

The exhaust gas from the HRSG then enters the air quality control system (AQC system). This generally consists of a common powdered activated carbon (PAC) mercury control system, a dry-lime scrubber, a bag house, an induced draft (“ID”) fan, followed by a Selective Catalytic Reduction (SCR) system and integrated stack. The AQC system is designed to remove mercury, acid gases, particulate matter, NOX and trace amounts of dioxin/furans. Most of the acid gas present is in the form HCl.

The reduction of mercury and other unwanted elements in the stack gases is accomplished by injecting powdered activated carbon (PAC) into a dry lime scrubber.

The entire AQC system uses programmable logic controllers (PLC), which automatically regulates and adjusts each component as needed. The system is also equipped with alarms for all component failures.

Dry-lime (CaO) is fed into the scrubber and combines with the acid gases in the flue gas stream to form various compounds of calcium. These compounds, together with unreacted lime and small amounts particulate matter are mixed in the gas stream and pass to the bag house.

In the bag house the gas stream is filtered to remove the particulate matter. Any un-reacted lime present on the surface of the filter bags serves to further remove any residual HCl from the gas stream.

The bag houses are of the pulse-jet type, where the bags are cleaned on line by a pulse of air directed down the centre of the bags. Each bag house is sectionalized into compartments so that one compartment can be taken off line for bag replacement or other maintenance while the gases are passed through the remaining compartments.

Oxides of nitrogen (NOX) is controlled in the SCR by adding the reducing agent, ammonia, NH3, to the flue gases after they have been heated to the required operating temperature. Supplemental heat is added to flue gases prior to entry to the SCR and is provided by two small natural gas fired duct burners. The reducing reaction that converts NOX to N2 and H2O occurs in the presence of the catalyst housed in the reactor located downstream of the ID fans. The catalyst also serves to further oxidize any remaining dioxins and furans that may be present in the stack gases to form HCl, CO2 and water vapor. Both endothermic and exothermic reactions occur here, with a net heat reduction of about 15% in the air stream.

A full capacity bypass stack is provided around the entire air pollution control system, including the ID fan. This permits emergency shutdown of the plant in the event of a total power failure, or a serious malfunction.

The main stack (SCR stack) contains continuous monitoring equipment is the exit point for the cleaned air leaving the plant.

At the end of the gasification process, a small amount of vitrified and inert ash drops into a specially designed water-filled auger system below the primary chamber, which cools the ash and delivers it to containers for final disposition. The sand-like vitrified ash is safe and is suitable for use as landfill cover or potentially as an aggregate in embankments or asphalt products.

The entire Facility operates 24-7 with minimal downtime for maintenance. A rotational schedule of preventative maintenance keeps other portions of the Facility operating while each gasifier is taken offline once a month for very short periods of time.

If there is a need, industrial waste as well as waste presently in the landfill may be used as fuel. Methane and/or other gases that would otherwise spew into the atmosphere can also be piped into The Hoskinson WtE plant as used as auxiliary fuel.
