By noon today the fire is still not completely out out as the plant houses two huge tanks, storing up to 100,000 litres of bunker oil.
The fire was reported to start at around 10.00 pm at the refinery plant of VKP Energy Co Ltd in Kamsakae Saeng district.
The plant used old rubber tyres as raw materials to produce bunker oil.
The fire happened inside the plant and quickly spread.
More than 20 fire engines were rushed to the plant and try to contain the fire in limited area.
However due to the huge storage of bunker oil in two tanks, firemen were unable to prevent it from spreading the whole building.
The building roof later collapsed after several hours of raging.
By 10.00 am today, the fire was still raging.
Initial questioning revealed that the fire broke out when a worker opened the furnace to fill in rubber tyres for melting.
But the opening of the furnace was said to be untimely, thus forcing the flame to leap out and catch fire.
The worker was seriously injured.
The fire was still raging before noon as the huge bunker oil of over 200,000 litres were still burning.
Initial damage to the plant was estimated at 40 million baht.
