More than 100 firefighters have been working to contain the blaze in Horseley Fields with witnesses reporting hearing explosions.
West Midlands Fire Service was called just after 21:00 GMT on Monday.
The fire was so large it was reported being seen more than 15 miles away in Shropshire.
One woman, who lives in the Bradmore area of the city, around three miles (5km) from the scene of the fire, told BBC WM: “The sky is red.”
A man who lives in Barr Beacon, 11 miles (18km) away, called the radio station to report seeing “a big fireball go up” and “large flames”.

Trains into the city were cancelled because the scene of the blaze is close to the main railway line and Wolverhampton railway station.
Avanti West Coast apologised to passengers who reported being stuck on their trains for up to two hours and said services had resumed, via an alternative route, by 01:00.
National Rail said rail users passing through the area should expect delays of up to 60 minutes throughout Tuesday.
Several roads in Horseley Fields were shut and police urged people to stay away from the area.
