The new bin lorries – costing around £250,000 each – will replace the existing fleet which is nearing the end of its serviceable life after more than seven years on the road.
The vehicles were acquired following a successful tender by Billingham-based Bell Truck and Van as part of the council’s Fleet Replacement Programme.
They will be used across the town’s waste and recycling service, with four of the new wagons fitted with electric bin lifts.
Middlesbrough Mayor Chris Cooke visited the Resolution House depot with Cllr Peter Gavigan, the council’s executive member for Environment, to check out the new arrivals and find out more about how they will be used.
Mayor Cooke said: ‘Modern refuse collection wagons are highly sophisticated pieces of machinery that carry out a task we all take for granted, day in, day out over a number of years.
‘Our existing fleet was at the end of its life, so I’m delighted to see state-of-the-art replacements ready to take their place.
‘It’s the kind of long-term investment that helps us deliver a first class service across the town, and one which I know residents value.’
