Clashes between drivers and protesters ensued after protesters blocked the junction with St Clements Way and London Road in Thurrock on Wednesday morning.
Many Isolate Brittany the members had stuck to the road, causing long lines of vehicles.
Some members of the group were dragged off the road several times by drivers, who took out their backpacks and clothes, before the protesters immediately returned to their seats to sit down.
Truck drivers honked their horns and some motorists snatched banners from protesters’ hands as they sat or stretched out on the road.
Meanwhile, a protester was nearly run over after pulling over in front of a blue Hyundai car and was reprimanded by the driver who told her, “This is stupidity.”
Images have also circulated online showing a mother stepping out of her black Range Rover and arguing with those gathered around her car.
“Get out of the way, my son has to go to school,” she told protesters.
“I don’t care what the problem is with f ******. My son is 11 and he has to go to school today, so walk away and let me take him to school. “
Police later arrived and pulled other protesters off the roads. Essex Police said 35 people were arrested.
In response to the incident, Essex Police said: ‘Officers were at the scene within five minutes and are currently working to resolve the situation quickly and safely. Arrests were made. “
Truck drivers have also warned that the protests could worsen the ongoing fuel crisis as tankers will not be able to reach gas stations.
A driver told LBC News: “If this protest stays here any longer, I’m afraid the night driver may not be able to deliver fuel to the garages or whoever.
“So speaking of truck driver shortage and fuel shortage, it can get worse today. It’s a hot spot.
“We also deliver to shops, bus garages, train depots, all of which are essential for transportation. “
Delivery driver Robert J Foulger, 57, said: “There were nine police vehicles there and countless officers who didn’t catch the criminals, costing taxpayers money.
“I took pictures while sitting in traffic trying to deliver fresh produce to a supermarket distribution center. I was on the mobile side of traffic so I didn’t wait long, luckily. “
The High Court granted national highways several injunctions against demonstrators blocking sections of the M25 as well as other major transport routes in recent weeks.
Injunctions mean that anyone who breaks the order risks a prison sentence, Transportation Secretary Grant Shapps said.
But despite this, the group returned to the M25 on Wednesday to demand the government isolate houses in the UK before winter, starting with the poorest.
Insulate Britain supporter Dr Diana Warner said: “A lot of people go out of their way to thank us. Some get out of their cars to thank us, some are police officers involved in our arrests. For them, we bring hope – we haven’t given up yet, we continue to push for life-saving changes.
“It’s a big step from thanking us to taking action. But if you make a gesture to help us, no matter how small, you will help us make the change. “
The group said on Wednesday that the action coincided with the publication of a report by the Shelter charity, which found that the health of 22% of tenants in England – or 1.9 million households – was affected by a substandard housing.
The report says people live in houses “which make them sick because they are moldy, cold, unaffordable and extremely precarious.”
