Around 40 vehicles joined the protest at County Hall

A convoy of about 40 lorries and other vehicles drove with their horns blasting from the Environment Agency's base at Llandarcy to County Hall.

Company bosses claim there are hundreds of skips on the streets of the city unable to be emptied.

Swansea Council says assembly planning rules are to blame.

We've got more than 100 skips in Swansea now with nowhere to go Steve Lorey

Until recently skip firms have used Swansea Waste Disposal's baling plant in Llansamlet and the Tir John landfill site on Fabian Way.

Now they say they are having to travel to Merthyr Tydfil to dispose of commercial waste.

Operators claim it will lead to a big increase in fly-tipping.

Steve Lorey of Allskips said: "There are builders who won't have a place to put their rubble.

"There are other people who just want to dump their rubble.

The landfill site at Pontardawe is no longer taking commercial waste

"We've got more than 100 skips in Swansea now with nowhere to go.

"We can't go to Merthyr - it is too far - by the time we've been there a couple of times the day is over."

Swansea Council said a private company operating a landfill site in Pontardawe was not accepting commercial waste because it was running out of capacity.

That meant the council could no longer use it to transfer commercial waste to.

A spokesman said businesses affected by the decision should take up the matter with the Assembly Government.

"The issues being raised by skip hire companies are the result of planning regulations which make it very difficult for local authorities anywhere in Wales to give approval for any new landfill sites," he said.

A planning application has been made to extend the landfill site at Pwllfawatcyn near Pontardawe.
