Scarp Tire Pyrolysis Factory



Kang-Jin Test

In 1998  Hyubwoo carried out the pyrolysis experiment by using leather tannery wastes collected from Koryo Leather Company and reclaimed oils and char. At the same time, chromium was reclaimed. Both is suitable for use in tanning process itself. It results in energy saving and efficient process for recovery of chrome in leather tannery industries. The Kang-Jin plant is capable and treating 48 tons of tannery wasters a day and 14,400 ton/year.

Why Pyrolysis?

The major steps of a basic chrome tanning process for a cattle hide include liming, bating picking, tanning and drying. Liming is performed with a 10% lime-sodium sulfide solution to loosen the epidermis and hair. Bating performs two function. Namely. Delimiting with addition of ammonium sulfate and modification of the hide cell structure through proteolytic enzymes to accept tanning agents. The pick treatment with mineral acid decreases the pH which is adjusted to suit the chromium salts employed. The leather wasted that derive from the waste Streams are organic in nature

Since this Waste is carbon based and contains little or no sulfur it will burn "cleanly" The material has a heating value range from 8,000 to 9,000 kcal per kg. The solid leather waste generally contains approximately 6-8% chromium as chromium oxides by weight whereas the liquid wastes contain approximately 1% by weight of chromium as chromium oxides based on the weight of the hide.

To date, no method has been proposed for treating or reclaiming tannery waste which would result in the efficient production of energy suitable for use in the tanning process itself while, at the same time, enabling chromium reclamation. It is also known that the heating value of leather ranges from 8,000 to 9,000 kcal per kg. Any reclamation process which could recover the heating value of tannery. Waste would greatly increase the thermal efficiency of the overall process. Instead, it is estimated that the solid tannery waste generated in a conventional tanning operation would be able to provide at least 50% of the energy required for the basic tanning process itself.

According to the method of the present pyrolysis solid tannery wastes are subjected to a relatively low temperature pyrolysis step to convert the organic portion of the wastes to a fuel product comprising essentially, hydrocarbon gases and liquids, and a residue comprising a trivalent chromium-containing ash and a carbonaceous char. The fuel product is recovered and burned to supply heat for the pyrolysis step and to a boiler or other suitable apparatus to supply hot water and/or steam for the tanning operation. It is to be understood that by pyrolysis is meant the process by which organic materials are heated to high temperatures in the absence of significant amounts of oxygen. i.e., in an inert or reducing atmosphere whereby the organic material is thermally decomposed into simpler components. Pyrolysis differs from incineration or combustion in that in the latter two processes the organic material is significantly oxidized whereas in the from no significant oxidation takes place. Pyrolysis of the organic material derived from tannery wastes generally where is the formation of three classes of product.

(a) A gas comprising hydrogen methane carbon monoxide and carbon dioxide

(b) A liquid mixture comprising water tar oil and other organics;

(c) A solid residue comprising ash and carbon

Simultaneously, the non-pyrolyzable residue is processed to separate the char and chromium-containing residue. The char, basically carbon, can be used as a water purifier as burned to produce heat. The chromium residue is processed to recover the chromium content thereof for recycle to the tanning operation.


Brief Economic Analysis

We investigated Koryo Leather Company(KLC) who is one of major leather companies in Korea. KLC is capable to treat 1970 sheet of cow hide a day now equivalent to 90 tons a day. Outline of KLC is as follows:

-Treatment capacity            :  1,970 sheets a day, 90 tons a year

-Tannery process                : CrO(OH)SO4, 3,000kg a day is used now

-Yearly wastes disposal       : 518,746 tons a year

-Wastes disposal cost         :  US$ 510,000 a year

-Chrome cost                     :  US$ 890,000 a year

-Waste water disposal        :  0.9 ton/sheet a day

-Bunker-C oil consumption :  2,400 ton a year and cost is US$ 451,000


Based on above available information we analyzed the economic feasibility in case of applying our pyrolysis plant and all wastes will be pyrolyzed and oil to be reclaimed. Brief analysis results is as follows :


- Oil production            : 2,993 ton a year, price is US$ 568,000

- Char production         : 1,834 ton a year

- Self-oil consumption   ; 328 ton a year for pyrolysis operation

- Excessed oil               : 2,665 ton a year

- Chrome reclamation   : 422 ton a year. Price is US$ 337,000.

Finally we reached at  the conclusion that all reclaimed oil from pyrolysis can be used for tannery process operation itself. No energy cost is required. At the same time, significant amount of chrome can be reclaimed, which can be used for process itself. It results in cost saving and reduction of disposal cost as well.

Brief results is summarized as follows :

-Reclaimed oil                              : US$ 568,000

-Chrome                                      : US$ 337,000

-Saving for wastes disposal cost   : US$ 510,000

-Total expected annual revenue is US$ 1,415,000


Pyrolysis plant cost is around US$ 3,500,000 but it may vary depending on site conditions and country situation. In conclusion, we are quite sure that this pyrolysis plant is viable and feasible. And also environmentally attractive to most leather tannery industries. If any question, please contact us. We are always ready to closely work with you and continue to develop new technology in fields.                                                                             






Poultry Pyrolysis Test


The State of Maryland in USA is one of large production of chicken and approximately 1,000tons a day of chicken manure is being disposed now. It is a critical problem to properly treat it.

It has been treated by making a fertilizer so far but such treatment may be no longer further possible because the fertilizer is not commercial value in market. In U.K there are many power plants which use the collected chicken litters as a fuel. To solve the problems, recently the State is open to discuss a feasible proposal from outside firms and also suggest financial support to the selected scheme.

In the mean time GTR in Baltimore, USA visited at our company on June 15~19, 1999 and tested the chicken manure in pyrolysis plant at Kang-Jin, Korea. It was first time in the world and reclaimed oil and char are being now analyzed in laboratory. According to other test reports, oil contents of chicken litters is about 50% of coal.  After pyrolyzing the chicken litter in this test, it was proved that the reclaimed oil from condensing unit was well burned.

As the lab. analysis proceeds, further details on this will be reported in our homepages for you reference.
