Robert Jenrick, the secretary of local government, said the boards should be sure to reopen the boards “as soon as possible”.
Greater Manchester Mayor Andy Burnham said: “Although we are reopening centers, it is not a return to normal.
“We ask the public to limit their trips and to go to a household recycling center only if absolutely necessary. “
To control the number of visitors, only vehicles with license plates ending in even numbers were allowed to use the centers.
There are also limits to the number of cars admitted to the sites, which only accept general bagged garbage.
Environmental Councilor David Renard, environmental spokesperson for the Local Government Association (LGA), said police should handle the “inevitable” traffic queues at tips.
He added that it was also essential that staff receive PPE.
Recent research by the Universities of Southampton and Portsmouth suggests that the spill of flies increased significantly in rural areas during the foreclosure.
This followed the closure of almost all boards due to the coronavirus and an increase in DIY projects caused by people stranded at home.
