Teams of firefighters have remained at the large fire at the former Alex Smiles recycling site.
The fire broke out at the Deptford yard early evening on Monday, sending a huge plume of smoke into the sky which could be seen for miles.
Up to 50 firefighters from Tyne and Wear Fire and Rescue Service battled the blaze at its height.
Today, the service has said crews have continued to work during the night, with three appliances, aerial ladder platform and a high volume pump in use.
It still had 19 firefighters on the scene this morning.
Drone footage by Mick Naisbitt shows the smoke rising from the site.
Northumbria Police also issued advice to people living nearby to close their windows and doors and stay inside and to those with health concerns.
The company went into administration in 2015 leaving creditors out of pocket by £7.5 million.
