Medway Norse has taken over responsibility for waste and environmental services in Medway.
Under the new seven-year agreement, Medway Norse will provide waste collection services to 111,000 residential premises.
The agreement, worth around £12 million a year, has seen 270 staff TUPE transfer into Medway Norse.
Andy Mann, Operations Director at Medway Norse, said: “We are delighted to build on our highly successful, long-standing partnership with Medway Council.
“We have been supplying a wide range of services to the council for almost seven years, and we have also built up a strong portfolio of external commercial clients, the revenue from which helps fund other services provided by the council.”
The new deal means Medway Norse’s annual turnover is now approaching £30 million.
