The Environment Agency (EA) has sent in its own contractors to start removing waste from a site which has been blighted by fire.
The EA said it was forced to act because the owners of the site in Swindon, Averies Recycling, had ignored an enforcement notice to do it themselves.
The warning was sent last week, ordering the operator to begin moving waste from the site, which has been on fire since late July.
The agency has now sent in its own contractors, Hills Waste Solutions, to remove up to 3,000 tonnes of waste, which is mainly non-recyclable commercial material, to a landfill site in Blunsdon.
James Mahoney, area manager at Wiltshire Fire & Rescue Service, said: “In the coming days, it is hoped sufficient waste will have been taken away so this more intensified firefighting can begin.
“This is a long and complicated operation and we are grateful for the ongoing support and co-operation of residents and local businesses affected by the fire, which we all agree has been going on too long.“
Averies Recycling could not be contacted.
