Various types of waste ocur as a resuls of Hydrocarbon exploration, drilling and production
activities. One of the waste type resulting from these activities is crude oil contaminated waste.
It is often considered as hazardous waste crude oil contaminated waste and is able to cause
environmental pollution by effecting water soil, air. Crude oil contaminated wastes are petroleum
contaminated soil, packaging materials, absorbents, wiping cloths and protective clothes. It is
necessary for these types of wastes disposal in order to prevent damaging to the environment.
Soil pollution occurs as a result of petrolleum spilling due to the problems that occur during crude
oil, of which hazardous waste type, production and transportation with pipelines. One method
for removal of oil contaminated soil is the elimination with the application of “Bioremediation
Process” used widely by means of TPAO and also other international companies. Bioremediation
which is a method of biological treatment of natural microorganisms using the hazardous waste,
is defined as a reduction of less toxic or nontoxic compounds. One of the most important factors
of soil rehabilitation is to provide in-situ bioremediation application. Cellulose fibers obtained
from recycled processes and bioremediation products comprising nitrogen and phosphorous
components that are necessary for he survival of those bacteries exist in the sport even thoguh
there are groups of bacteria in the product. Those bacteries being in contact with water and
hydrocarbon divide and increase rapidly. Adsorbed hydrocarbon waste (activities of bacteria)
converts to the completely harmless bioenergy by means of bioremidetation process in 90-240
days. One of the another method used for soil rehabilitation and used by means of TPAO is
notralization-stabilization. In this method, contaminated soil is rehabiltated with the certain
portion of ash, clay, lime, soil or cement, which is determined according to petroleum content.
In addition to two methods, mentioned above, packaging materials, wiping cloths and protective
clothes, and so on disposed in mobile incineration systems (waste incinerator) located at the
activity areas.
