Abstract: The true need in waste
management is the elimination of organic waste featuring the
conversion of wastes to high value marketable products in
a manner sufficient to support the costs and profit, derived
from waste raw materials. Locally organized corporate entities
will specialize in this advanced treatment of waste using
the Gravity Pressure Vessel (GPV), invented by James Titmas
and marketed by GeneSyst International, Incorporated, which
can be used to convert waste into ethanol and other by-products.
Such a paradigm shift in approach involves remarkable intrinsic
merits for the host community, whilst introducing significant
challenges in overcoming the status quo. Deliberate steps
must be taken to accomplish that shift with a plan to mitigate
the risks involved not only for the responsible local administrative
parties, but for the permit writing authorities as well as
the capital investor, but for the established practitioners
and means of waste disposal as well. This presentation considers
the complications involved in bringing a new technology to
the market, the inherent resistance to change, and an insight
in to why it takes several decades to introduce and establish
a viable alternative to mature waste management practices
and finally, how to contain and mitigate potential risks involved
in the transition to a new way of doing things.
Economic Merit: By using this
sealed and closed process, wastes can be handled directly
inside the population center. Money paid for this service
stays in and re-circulates in the municipality in the form
of wages paid for labor and support services as well as the
fundamental economic merit of selling products made in the
community. The reversal of the economic cash flow from export
to import of cash for recirculation within a metropolitan
area has great impact and amounts to the equivalent of hundreds
of dollars per person, each year. It is estimated that if
all a city’s many forms of fiber based waste were converted
to Ethanol, as much as 15% of vehicular fuels needed in the
city could be produced in the city, thus reducing the drain
of urban dollars for imported fuel, goods and services, and
at the same time avoiding capital drain experienced from waste
exporting services. The process of converting garbage and
trash to Ethanol and other byproducts converts a cost to an
income. This program reduces the demands from wastes collection
and transport on the infrastructure of roads within the city.
Persons in the city will be employed to prepare the products
for market, sell the products, and transport these products.
Environmental Merit: The use
of renewable organic material, such as fiber based waste,
produces no net gain in greenhouse gas as the sources are
not fossil fuels. Any fuel that will reduce the residuals
of the partial combustion of fossil fuels will result in cleaner
air and reduced health risks. Ethanol as a gasoline additive
is an effective alternative to either Tetra Ethyl Lead or
MTBE, both of which have serious environmental side effects.
The practice of land filling produces one cubic meter of methane
for every 4 kilograms of biodegradable organic debris buried
in the ground. Methane is a greenhouse gas many times more
significant than carbon dioxide and that landfill process
is reported to represent 25% of global greenhouse gasses.
Incineration does dramatically reduce the volume of waste,
but tragically results in very significant acid gasses and
toxic metal after-products. The process does not require separation
of wastes by the citizens or businesses of the community.
Wastes separation as necessary for the process will be accomplished
at central service centers increasing efficiency, safety and
efficacy in both collection and salvage yield. Timely, clean
and efficient collection will reduce vector health complications
associated with rodents and insects. The image of the city
will be enhanced and restore the reputation of the city as
a center for quality urban management and services, using
free enterprise resources. A cleaner city contributes to the
quality of life.
Legislative and Liability Merit: The city would not have to
export wastes to other jurisdictions thereby gaining control
over liabilities and reliability of wastes management practices.
Because the process is based on free enterprise incentives
and costs benefits, no flow control or artificial legislative
regulation is mandated. The entire capital cost is privately
sponsored. The process meets and sets the standard for present
and anticipated wastes disposal regulations. Given ultimate
disposal of the waste materials, insurance companies, for
the first time, can quantify the risk of wastes management.
The open ended liabilities of wastes storage (land fill) are
avoided with clear cost predictions relating to insurance
coverage without transferring the long term storage risks
to the public domain. Every land fill incorporating biodegradable
organic debris will putrefy over time, resulting in the loss
of containment of the entire inventory of biodegradable materials.
Beneficial use Merit: Once collected
and delivered, and using local labor, the wastes will be converted
to products including Ethanol (an automobile fuel oxidant),
Furfural (an industrial chemical), Yeast (a protein food supplement),
Liquid Carbon Dioxide (used for flash freezing foods), Urea
(used as fertilizer), Lime (used for road foundations and
agriculture), Acetic acid (used in industry), and other products.
The reduction in wastes volume will exceed 90% of truck weight
as collected and delivered to the facility in the served community.
The conversion to these products have the advantage that they
can be stored or transported without significant loss in value.
Neither steam, methane or electricity can be stored or exported
at minimal costs from the metropolitan area and still retain
their value. While some studies focus on the energy balance,
that is Kilocalories or British Thermal Units in verses those
same heat content units out, they miss the point of the economic
merit of the form of heat energy. Ethanol, as a clean burning
and portable fuel, has a market value (heat content per heat
content) many times the market economic value of non portable
or fixed base energy use fuels such as steam boilers or electric
generation fuels.
Transitional Considerations:
Most every community already has some method at hand to deal
with the disposition of waste materials. It may involve either
public or private investment in collection, transport, destruction
or storage of waste materials. These methods can represent
important investments made by either the local government,
private enterprise, or both. In reality no community can arbitrarily
and instantaneously stop what they are doing and make a sudden
shift to a new way of doing things. The appropriate path is
to introduce the new technology and then, over time, ramp
in a greater percentage of market share based on several factors.
These factors include employee and staff/administrative training,
public education and acceptance, proven efficacy and efficiency
on that community's waste materials (each community has a
different recipe of wastes at hand), and the reasonable allocation
of time for the amortization of the investment in the existing
wastes management infrastructure. In most instances the emerging
technology should join forces with the existing wastes management
processes, motivated by the natural drawing card of enhanced
profitability, efficacy and the other attributed merits as
delineated hereinbefore. It is not the goal of these emerging
methods to be simply cheaper than existing means, but to be
competitive with those means whilst at the same time being
more profitable.
The community consensus: What
is not obvious how a community interacts to accept the process
of investment in time, energy and resources of all types to
accomplish any critical need of a metropolitan area. The need
is to accept that a community acts as a "ROUND TABLE"
to accomplish long term and vital needs of the community.
In fact it does take time for a host of various interest groups
to concur in how the resources of the people will be used.
The educators: even though the
essence of invention is a teaching. Beyond the self-motivating
goal of answering a need for the private gain of the process
practitioners and investors, there is a critical need for
those who have elected to be professional educators of engineers,
and plant operators to define, construct, and operate this
new process. This must be part of undergraduate education
as well as continuing education at both the Bachelor of Science
level and the Technical College level. The time required to
introduce new technology to the professors, place the technology
in textbooks, and produce uniform educational standards requires
at least a generation of educators.
The lawyers: a new patent or
method can not proceed without those skilled in the legal
arts. It can not survive without those who are skilled in
Civil law defending ownership and authorship as well as risk
and liability identification and the just authorship and application
of the laws. It is of marginal value without the art of the
interpretation of laws to sustain the pressure to appreciate
that there is a need to do a better job at keeping our life
space clean. These attributes extend to the Judges as well
as the staffs of government agencies that interpret the regulations
and author the requests for presentation into the competition
to win contracts for the means to manage the community's wastes.
The legislature: what can and
can not be done with efficiency, safety, and cost effectiveness
is at the heart of the intent of the law to cause a utility,
government agency, industry, business, or citizen to do a
better job in the way it imposes its wastes on its neighbors,
or those with an impaired political voice. Often large communities
elect to export their wastes to an area were the population
is poor or sparse, or both. A sort of convenience that may
result in a tyranny of the majority. If the legislative body
comes to appreciate that they are exporting wealth and resources
the nature of there actions will come to alter how wastes
are actually managed.
The medical profession: just
what is pollution and what is not pollution depends on its
impact on life forms, including human beings, our domesticated
agricultural dependents, and the flora and fauna in which
we find ourselves in the role of a protector. The new wave
of understanding will include how combinations of materials
affect life quality, not just this chemical or that chemical.
We are creating chemicals faster than single chemicals can
be tested, and the tests for combinations of chemicals is
at least one hundred times as difficult, and is only just
beginning. The law now reads that the treatment required is
based on the capability of existing equipment. The medical
profession, doctors as well as veterinarians, will have to
say what has to be done with less reliance on those who sell,
specify, or select waste treatment equipment.
The financier: without organized
and disciplined investment nothing of this magnitude can be
built. This is true of both public and private funding. Education
and fiscal management here are intertwined. If a Broker does
not understand the true liabilities in mature waste processing
technologies or the accumulating liabilities of “waste
storage” technologies an investment will fail. The motivation
for change must be understood with a balance established between
the cost of money and the probability for success of any waste
handling process, new or mature, and money availability adapted
to that knowledge. Universal understanding in these collateral
professions follows the acceptance by the technical, political,
public relations and academic professions. None will be so
lost as the financier that does not wish to get involved in
appreciating the techno-marketing implications.
The public agency administrator:
if something can not be Permitted, it can not be built. There
is a tendency for those who elect to invest, especially in
new technology, to keep that technology a trade secret. That
contradicts the Permit procedure which is based on specific
knowledge of what is to be built and the appreciation of the
Permitting authorities that what is to be built has the capability
to perform. Here the quality of academic institutions and
the academic qualifications of individuals granting Permits
are intertwined. The nature of gravity pressure vessel operation,
especially the absence of operator exposure, the absence of
an air emission, and the absence of toxic residuals, and the
absence of reliance on storage is fully consistent with the
objectives of the Permitting authorities.
The public media interests:
we must all fully understand the merit of this kind of education,
be it radio, television, or newsprint, movies, or magazine
articles. The media teaches us in many ways. They teach the
public, and the politicians. They give a confidence to the
investor, and alert the technical world that tends to live
in its own shell. Media is the key to knowing what others
are doing and by their screening give credence to those chosen
for exposure. They also identify and reinforce where the public
interest lies. The graphic capability of the media can convert
technical knowledge to lay knowledge. We are a copycat culture,
and no one is so broadly influenced by the media than our
law¬givers, their agencies, and those persons who ultimately
make the political selection of where our environmental dollars
are invested. This is a self feeding arena as the media responds
and expands on the public interest they actually foster.
The environment advocate interests:
We have a great deal of sympathy for the instincts within
all of us that assert a natural understanding that wastes
of all kinds are adverse to our health. The NIMBY (Not In
Our Back Yard) spirit lives, and the more we discover through
hard analysis, the more we realize that intuitive understandings
can have a valid foundation. Indefinite storage must not be
described as disposal. Health and human impact from wastes
on one person in 2,00, 20,000 or 200,000 may be well and good
if you are not personally involved. The ultimate threat comes
from those who assume that storage will maintain its integrity
forever, which it obviously can not. In time all storage configurations
must deteriorate, and thus threaten its locale.
What is our role? Our role in all this, by our own choice,
is to be that of a person that offers a solution to all these
parties that have been listed here as role makers. We are
just one tooth in a gear with many teeth. This wheel must
turn for many years before each tooth knows what the other
teeth are doing, and what they know about what the others
know, to have merit. I have spent my entire adult career as
a practitioner in the field of Civil Engineering, with special
interest in wastes treatment. Hundreds of times over the last
four dozen years clients and friends have asked me “What
can be done”, and I have shown them what can be approved
and funded. In my own heart I wished I could do better, and
given them a wider management choice.
We in the sanitary engineering
profession have known for a long time what the ideal waste
treatment tool should be like. It must actually destroy waste
or convert it to a useful product. It must do this in a closed
system. No shell game. No conversion from wastes in water,
to air or land or back again. It must be economically competitive.
It must confirm the effectiveness of the procedure before
the waste is released from control. The waste must be so processed
faster than it is being created. The greater the population
density and extant, the higher the standard for wastes control
must be. It must accomplish the task at hand without leaving
the site of waste creation and not depend on cross country
or cross global transport.
Nothing is so bizarre than paying
the cost of shipping of wastes from one location to another
if we are not going to do anything better than bury it, or
dump it in water, or throw it in the air or on the land, or
even some combination of these. The risk of spill is great,
the prospect of loss of control absolute, it is a waste of
resources and money, and it carries a profound probability
of imposing wastes unjustly on the poor and the politically
weaker population.
Risks and Liabilities: In any
commercial endeavor, liabilities exist which may impact the
return on investment. Liabilities can be mitigated using conventional
techniques known to the industry, and executed using qualified
and educated personnel. These techniques include initial and
ongoing training, design for waste minimization, insurance
procedures, safety planning, subcontracted specialization,
and bonding. Although this will not eliminate all liabilities,
it can serve to divert liability considerations to non-recurring
expenses and create an internal discipline whereby costs are
specifically invested area by area to limit liability exposure.
Finally, the most significant liability of all is the philosophical
selection of which environmental technology to invest in.
Training considerations: An
estimated eighty percent of all industrial waste discharges
can be attributed to loss of product through human error.
The initial and ongoing training of personnel in work safety
and emergency procedures is vital to the facility’s
ability to handle a spill or off-specification product. This
technique has two components, first is the training, and second
is the design of the facility itself to contain and reprocess
spills, leaks, and off specification products. When employees
understand why a safety procedure is needed, they are more
likely to accept and follow those procedures, thus avoiding
spills and improving response when spills occur.
Fundamental design approaches:
There are certain precautions that can be economically designed
into a new plant which would be very cost effecive. Some of
these are driven by EPA and other permit procedures, and others
by the economic value of controlling the loss of product.
One example includes sheltered spill containment. Simple roof
structures over secondary tank containment will prevent rain
from mixing with spilled or leaked product. This will allow
the products to be reprocessed within the system. Another
example is the recovery of vapors lost when transferring liquids
from tank to tank. Tanks will be connected by vent pipes,
so that as one tank empties into the other, it will be filled
with the air from the other tank instead of outside air, thus
preventing vapors from escaping. This has both safety and
economic benefits. These are liabilities which are minimized
by initial design concept.
Insurance coverage: Within limits,
monies can be invested as a safety net to control the impact
on the return on investment using insurance coverage. In selected
governmental jurisdictions, worker’s compensation, unemployment
insurance, general liability insurance for employees, and
to some extent health insurance are included in employee costs
as cost of sales, administration, or production as a part
of annual salary allocations.
Safety Planning: As in environmental
permitting, the handling of industrial materials safety has
become institutionalized through the permit procedures. Examples
include OSHA, and the local fire, building and safety codes.
These permit applications direct the applicant to provide
for safety programs that are standard in the industry. For
instance, how are combustible liquids handled, what explosion
control provisions are integrated into the electrical system.
Not the least is the qualifications and abilities of properly
applied and motivated supervision techniques. In the brief
biographies of the key members of the program, the reader
will note the number of safety awards garnered by Donald Bogner
in the very difficult safety control field of heavy construction.
That is a combination of planning and presence of mind in
an atmosphere of confusion.
Qualified subcontract specialists:
Certain aspects of any industrial enterprise can be managed
best from a liability standpoint through selective subcontracts.
Two of the most common include initial construction and the
handling of a unique material. In this instance, an example
of the latter is the storage and controlled delivery of Oxygen
for use in the process. Rather than assuming a liability for
this commodity, it is safer, simpler, and even cheaper to
pay a trained vendor to supply oxygen at an on site facility
and pay him a unit price for every ton delivered to specification.
The liability control costs are included in the unit price
of Oxygen.
Insurance Bonds: The easiest
example of liability control through Bonding is the contractual
relationship between the owner and the contractor erecting
the facility. These may include bid bonds, performance bonds,
and maintenance bonds, all in addition to the contractors’
own set of employee insurance precautions. In the execution
of most projects the failure of a sub-system is typically
identified as related to the installation of a key piece of
equipment. Does it pump at the rate and pressure specified,
is the wiring correct, is the control correct? Do the various
construction disciplines interlock without gaps between their
responsibilities? These issues as liabilities are mitigated
through the Performance Bond, which covers the period between
the start of work and the Engineer’s Certificate of
Substantial Completion which memorializes that date by which
the facility is able to function as intended. This is augmented
by an extended bond period referred to as the maintenance
bond, wherein parts or components which fail prematurely are
replaced. By agreement, these may be for one or more years,
and serve as a bridge between the contractor efforts and the
in-house maintenance staff.
The fundamental question which
must be answered by an investor is “Where should I invest
my money?” In order to answer this question, the investor
must educate himself on the investment opportunities, including
but not limited to short term and long term profitability,
short term and long term liabilities of the process, capital
costs, and current and future laws and regulations which will
impact the process. When evaluating waste technologies investments,
there are only a few choices. The option of Landfill is merely
a method of accumulating liabilities. Another option is Incineration,
which converts solid waste into an airborne waste. This only
changes the liability. The final option is conversion to a
beneficial use product.
With conversion to beneficial
use, one must evaluate the marketability of the products.
In the case presented here, alcohol is a highly marketable
product. The next choice is what will be the source of raw
materials for the process. Two options are readily available
to the investor, newsprint and municipal solid waste fluff.
Since one must pay for newsprint, and can be paid to process
fluff, fluff is the more economically sound choice. With the
source of raw material, a process must be chosen to convert
this fluff into fermentable sugars. Two options available
are enzymes and acid hydrolysis. The use of acid hydrolysis
is more reliable and less expensive than use of enzymes, and
produces a sterile interim product despite the obvious broad
spectrum contamination of the raw in material.
The adaptation of any process:
All enterprises have liabilities. Any that can be identified
prior to the fact can be mitigated using techniques common
to the arts of design, construction, and good management.
Those that can not be predicted will occur and impact the
return on investment. By prudent administration, these will
become one time expenses and controlled through expanding
on one or more of the above delineated liability control measures.
The single most important factor in limiting liability is
education and understanding by the principals and the investor.
Stage one: At the inception
of this four-stage process, the engineers and the client shall
agree on an initial budget for stage one activities, and the
mechanics of the process funding. Working with the existing
inventory of the waste to be processed in terms of components,
location, configuration and quantity provided by the client,
the engineers shall rough out a conceptual cost/benefit analysis
and schedule the procedural and subcontract program to effect
the stage two evaluation. Budget and cash payment terms will
be agreed for the next stage. The engineers and the Client
review the existing or historic costs of disposal for the
target services. The role of the Client's existing consultant
is integrated into the program. Based on the technical and
fiscal merit of the stage one presentation, and on approval
by the client, the process will proceed to stage two.
Stage two: includes a laboratory
simulation of what will go into the process, and what will
come out of the process. It includes selection and collection
of representative waste samples, transport of the samples
to the respective objective testing laboratories, initial
analysis, an initial target conditions simulation, a post
simulation analysis, catalyst option analysis, procedural
analysis and interim report. Subsequent repeat cycles may
be conducted for yield optimization. The engineers and the
client will review the results and confirm the procedural
optimization and define the required peripheral support equipment
for pretreatment and post treatment needs.
During stage two the range of
wastes verification will be checked. This will include rate
of growth, water volume, planned changes in production, periodic
cycles, seasonal variations, waste component variability,
flexibility requirements, and the permitting plan. Cost estimates
are advanced to a condition of closer focus. A site is selected
within or adjacent to the facility and transport requirements
are defined. A geological profile and bit program are developed
to define costs for drilling. Turnkey construction costs for
the facility are polished and along with schematic drawings.
In the alternative, a privatization proposal may be provided
to the client if requested.
As an option in stage two, the
investors may invest in a pilot plant to scale up the conceptual
design to about 5 to 10 percent of the capacity of a production
unit. One of the drawbacks of a gravity pressure vessel is
that it cannot be made small, and a pilot plant may cost as
much as one third of a commercial unit. The purpose of a pilot
plant is to correlate the engineering calculations with a
reduced scale facility and to upscale laboratory predictions,
and last but by no leans least, serve as the vehicle to train
plant employees as well as the plant supervision and administrative
staff..
Stage three is the full-scale
production facility. It is initiated by the definition of
contract effort using detailed engineering drawings and specifications,
the application for permits as required, the selection and
ordering of long term delivery components, activation of lease
agreements, and property access for initial construction and
drilling. During this stage all performance guarantees, including
performance and maintenance bonds, of the executing contractors
will be formally documented to the benefit of the engineers
and to the client. The engineers and/or the client will establish
an escrow fund for the retirement and closure of the facility
after all operations have ceased or at some pre-selected calendar
date. The engineers will be responsible for all construction
management services. Toward the end of the actual construction
stage both dry and wet runs of the operation and troubleshooting
will be conducted by the engineers exercising all aspects
of the program including safety, security, collection, transport,
pre-treatment, processing, measurement, post-treatment, and
residuals disposition. This ongoing procedure is anticipated
in transition to specified facility performance levels.
Stage four: is the operation
and maintenance stage. During ongoing operation, the engineers
shall provide services for a contract fee including real time
and remote performance monitoring, maintenance oversight,
ongoing operator and maintenance staff training, re-calibration
of meters and instruments, and performance review annual reports
for the client. From time to time technical upgrades to the
process are anticipated and an option will be provided to
the client for incorporation of those improvements in the
client's facility. The operational stage tenure will be on
a contracted basis and may last from one to twenty years as
agreed between the project technical staff advisors and the
client.
