Milson, who has run ACB Any Car or Bike since 2017, said “the pictures do not do it [the extent of the fly-tipping] justice”.
He said he has captured it happening with his own cameras and it was “always the same white lorry and usually the same person doing it”.
He said he had provided the evidence to Broxbourne Borough Council.
Last year he said there were six incidents of fly-tipping on the industrial estate including on 28 December, four days after another incident had been cleared.
This year business owners discovered a large amount of waste on 30 March outside TC Commercial Repairs, which is opposite ACB.
“I am riding a motorbike into work and came round the corner and nearly went on top of it,” Milson said.
He contacted Hertfordshire Police and the waste was removed by the council the next day.
