PRTI
Product Recovery Technologies International of Raleigh, North Carolina is the exclusive
patent holder of a cost effective rubber depolymerization system for use in fractionalizing
rubber and used tires into gas, steel, oil and carbon products. At PRTI, our highly efficient
low temperature process was developed in a robust commercial production environment
over the last nine years. This system operates below all EPA emissions limits, is completely
sealed and emits no waste bi-products or hazardous vapors, which makes it suitable for use
anywhere, even in populated areas. PRTI’s six chamber system processes up to 36 tons of
scrap tires per day. This advanced technology is seen by the tire and rubber industries as an
important element of an integrated solid waste management protocol that conserves natural
resources and reduces landfill material and air pollution. Our experience in recycling science
is extensive and this latest advance makes PRTI a world leader in depolymerization technology.
The Scrap Tire Problem
llllll
The proper disposal of scrap tires is a worldwide problem and
u
hundreds of millions are still being stockpiled in the United S
t
States alone and millions are added weekly. Most of these
t
tires are dumped in landfills or burned for energy recovery
as tire derived fuel (TDF). A small percentage are used in
civil engineering projects and ground rubber applications. Tires have also been chipped and
used as an asphalt foundation material as well. But in at least two instances the tires selfignited, creating serious environmental problems and clean-up expense. The PRTI system is
unique in that it breaks down the tire into its original building blocks. Our continuous high
volume process decomposes rubber into marketable products economically and efficiently
without substantial environmental concerns - a breakthrough in modern tire reclamation.
The PRTI Solution
h
The global community understands that dealing with solid
waste by dumping it in a hole or burning it is not the most
responsible method of disposal. These methods simply shift
the problem into the future, leaving a legacy of pollution and
waste. Landfills are closing as regulators impose ever more
stringent requirements, and incineration is a dirty outdated
solution in light of climate change concerns. This reality makes the PRTI system the best and
only profit driven solution for scrap tire disposal currently available.
PRTI Recovery Products
As tires are broken down in the depolymerization chambers, they are separated into
marketable components and the output is refined into these four basic product groups.
Carbon
hjh
The PRTI solution yields carbon as a by-product that is
used by industry for a variety of applications. It is most
commonly an additive, which provides reinforcing
properties to rubber in products like hoses, belts, rubber
sheeting and other industrial applications. Our plant can
produce about 5 tons of carbon per day.

Recovered Industrial Steel
Each tire we handle recovers approximately 2.5 pounds of
b
steel belts and bead wire made of high carbon alloy. Due to
o
the brass and copper coatings used, this metal is recycled
t
to foundries for smelting. The Institute for Scrap Recycling
I
Industries ranks our recovered steel as level one, which is
.
their highest quality rating. At full plant capacity this can
yield about seven tons of steel daily.
Electric & Thermal Power
One of the most exciting aspects of the PRTI system is that
it can be net zero to the grid when it comes to electrical
power. The syn-gas produced during the process powers
a gas generator that provides enough surplus energy to be
sold back to the grid. This process can also recover the
thermal energy to power an on-site steam turbine as well.
Combustible Fuel Oil
A full gallon of light oil can extracted from each 20 pound tire
t
the PRTI system can process daily, yielding over a million
y
gallons a year. Independent analysis shows our oil has
very h
high cetane value and provides excellent HFRR based on
lube c
content. Our oil has many applications in the blended
fuels market and related industries.
