Police recovered 80 tonnes of equipment, including tents and toilets, that will go to landfill.
Senior officers have been in talks with ministers about potential changes to public order legislation since the action in April.
These could include banning orders to stop activists who repeatedly protest unlawfully, and a new criminal offence of attaching items to the road.
Scotland Yard have foiled 24 terror plots since April 2017
Investigators have disrupted 24 terrorist plots against the UK since April 2017, Metropolitan Police Commissioner Cressida Dick has said.
Dame Cressida, Britain’s most senior police officer, revealed that 16 were international inspired Islamist-based plots while the remaining eight were fuelled by extreme right-wing views.
In September, head of UK counter-terrorism policing Neil Basu said that 15 Islamist potential attacks and seven extreme right-wing plots had been stopped.
Since January, the number of foiled Islamist plots has risen from 14 to 16, and the number of far-right from four to eight.
The latest figures came amid a Government consultation on plans for tougher sentences for terrorist offences.
