Q) Describe the system, how it is constructed, what it
does to the waste (especially how it destroys pathogens),
the compost by-product, and time sequence from the first
use of a cell through harvesting of the compost.
A) As outlined by Ronald Albrecht, a grant advisor to
RWF, The main elements of the facility are a reactor bed
and a curing/storage area.
1) A crescent shaped earth berm with an access road
and work areas on the top. The berm serves as a work surface
for the equipment used to transport and place the wastes
into the reactor and acts as a back wall for the materials
used in the reactor. The roadways and work areas are hard
panned with crushed stone to provide all weather access
and aid site housekeeping. It also diverts oncoming surface
water around the reactor as part of the environmental
2) A reactor built of carbonaceous material able to
support microbial life. Conventional earthmoving equipment
is used to place that material with the berm acting as
a back wall. It should be noted that any high carbon material
capable of supporting microbial life, not subject to rapid
decay, and having sufficient structural strength to maintain
the bed shape without undue settlement can be used. Suitable
materials include straw, wood chips, sawdust, and bark
3) A compost curing and storage area located at the same
elevation as the berm provides for the further enhancement
of the compost and the accumulation of large quantities
of compost to satisfy seasonal market demand. A truck
loading ramp is adjacent to this area.
Q) What is the size of the market for RWF's process?
A) At this moment the actual size of the market is very
difficult to enumerate. This is because the process not
only works for the small farmer, but large municipalities.
Given the opportunity, the RWF method can handle any carbon
based waste, therefore opening up the system for worldwide
Q) What specific market segments will the firm pursue?
A) The RWF method would like to pursue the areas of agriculture;
small farms, large farms, and industrial farms. Any industrial
business that produces carbon based waste, for example
furniture factories is a candidate. The RWF method would
also focus on municipalities, ranging from small towns
to large cities.
Q) What is the smallest and largest waste stream that
would be practical for application of the RWF method?
A) The smallest site would be a minimum of 100 cubic
yards of reactor base while the largest would be above
200,000 cubic yards.
Q) What is the anticipated impact of new environmental
regulations in various states (must systems be approved
by state regulators and does this system qualify?), at
the national level and in other areas of the world?
A) The RWF method is designed such that it can conform
to any sensible environmental regulations.
Q) What is the market share of competing systems and
how will RWF compete with them on price, environmental
impact, and customer service?
A) Large composting systems are relatively new to our
economy, therefore it is very difficult if not impossible
to determine the actual market share of each different
system. There are however, many different systems, which
include static piles, windrow, and digesters. The RWF
method is superior to all three in time energy and economics.
The static pile system is technically cheaper in initial
cost than the RWF method, but requires 100% harvest which
increases the total cost and lowers the piles efficiency.
The windrow method because of its specialized equipment,
turners, is only second in price to the digesters, turners
start at $300,000. Windrow is also inferior to the RWF
method in that it can only handle 7,000 cubic yards an
acre as opposed to 40,000 cubic yards. Digesters are by
far the most expensive method of composting. They require
large buildings, specialized equipment, computers, and
constant monitoring. Digesters require high maintenance
and produce an inferior product.
Q) Are you just selling a license to use the technology,
or are you selling a turnkey system with or without follow-up
A) For best quality control we plan on selling a turnkey
system with technical follow-up assistance.
Q) To what extent will you sell to the final customer,
and to what extent do you plan to work with other organizations
that will represent and install the system for clients?
A) In the beginning RWF will work directly with its clients,
both in installation and technical support. As the company
grows it will probably be necessary to work with some
sort of organization for installation. RWF will, however
always be available to technical support.
Q) What is the risk of someone copying the process with
some slight variation in order to avoid the patent restrictions?
A) We can not see an area that can be manipulated in
order to avoid our patent restrictions. As far as RWF
can tell any area that may be manipulated in hopes of
avoiding the patent protection would either compromise
the product, or directly infringe the patent. Please refer
to the patent.
Q) Does the patent protect the process from all feasible
Q) Does the potential for changing environmental regulations
pose any significant threat to the business? Anything
A) As long as the new regulations are sensible to large
scale composting the RWF method will be able to accommodate
any new regulations. Due to the fact that the environment
only composts aerobically or anearobically there is very
little room for change.
Q) What is the durability of the system and are there
any issues regarding its sustainability over time?
A) We have found that a thirty foot pile, measuring 200
ft. by 30 ft. by 30 ft., is able to withstand a truck
weighing over 22 tons with no significant structural changes
to the pile. With minimum maintenance the reactor bed
will retain its integrity for hundreds of years.
Q) What will be the ongoing operating cost for the client?
A) The client will be able to choose from four different
operating methods. Cost of operation depends solely on
which method the client chooses. The first method is an
aerobic anaerobic static pile, the least expensive system
to operate. It requires only a back hoe and, if desired,
a truck. Daily cost is determinate on how vigorously the
client uses the reactor bed/bioengine. The second method
is an aerated, anaerobic aerobic static pile. The price
of this system is determined by the equipment to aerate
the reactor pit, be it manually operated or automated.
The third method incorporates water injection and is also
determined solely on the equipment chosen. The fourth
method is a system that injects both water and air into
the reactor pit. Again the operating costs for all three
methods of injection depends on the type of injectors
used. The overall cost for all the systems is determined
by the rate of speed the client wishes to run the bioengine.
Q) How does the compost figure into all of this as a
product with market value?
A) As has been seen from the small home gardeners need
for soil to the large scale landscaper and farmer, the
market value for a quality fertilizer and topsoil replacement
is in high demand.
Q) What experimental results do you have to verify the
quality and efficiency of the system?
A) We have tests and results from the sites at Hardin
Rd., Berea, ASU, and the Surry County Farm, and will produce
the results upon request.
