Waste4Fuel's High Court hearing starts today.
The hearing, which will last up to three days, will begin at the Royal Courts of Justice in London at 2pm.
The court will hear the Environment Agency (EA)'s case against Waste4Fuel, whose site in Cornwall Drive, St Paul's Cray, has caused misery for people living nearby.
Fire services have been called to the plant 12 times in the last year, with residents voicing concerns about the health implications of fumes being emitted.
Waste4Fuel site in September last year
In November last year, the EA acquired a High Court order requiring all combustible waste be removed from the site by May 1.
At the end of March, the EA, concerned the order was not being complied with, went up against Waste4Fuel, former company director Bryan Hughes, new company director Shelley Hurst and site manager Jonathan Beckson at the High Court.
Waste4Fuel had been seeking to bring more waste per week into the Cornwall Drive centre.
The EA sought contempt charges against the defendants, who were then given 28 days to prepare their legal defence.
