Premier Waste fire was 'accidental'
A fire at a waste recycling plant involving 500 tonnes of paper is believed to be accidental.
At its height, 75 firefighters tackled the flames which broke out at Premier Waste on Walsall Road, in Perry Barr early on Monday.
West Midlands Fire Service said crews remained on site until Tuesday afternoon to check for "hotspots".
A spokesperson said there was no evidence to suggest the fire was started deliberately.
Premier Waste was open for business on Monday. It is not clear how much damage was done by the fire.
The fire was one of nearly 20 to hit recycling plants in the West Midlands area this year.
The fire service described the Perry Barr fire as about "half the size" of a blaze caused by a Chinese lantern at a recycling factory in Smethwick in June.
