The move comes following a mutual agreement in principle, to end the current waste collection partnership between the City Council and Amey.
A spokesperson for Amey said: "Amey and City of Wolverhampton Council have worked closely for the last 11 years, delivering an effective waste collection service for the city's residents.
"However, with local authorities facing ongoing and unprecedented pressures, both parties have mutually agreed to end the current contract.
"Both parties are now working towards the final agreement which will result in the waste collection services being delivered by the City Council from September 2018.
"Amey is committed to maintaining our positive relationship and delivering ongoing services for Wolverhampton residents for the remainder of our contract.
"Amey remains a major player in the environmental and waste market, and across the UK, has numerous local authority clients, over 16,000 business customers and four new waste treatment sites in planning, construction and commissioning stages."
Councillor Steve Evans, Cabinet Member for City Environment at City of Wolverhampton Council said: "Through these changes, the council are able to meet its agreed budget whilst investing to provide a platform for service changes as agreed by full council in February last year.
"The new service will introduce an improved waste collection service to be easily accessible and more efficient to residents by enabling them to self serve and book specialist services provided by the council.
"We will provide a detailed implementation programme and will ensure residents are kept up to date in advance of any service changes, while keeping them our number one priority throughout the process.
"Moving forward, the new service will also enable the city council to increase recycling requirements to 50% by 2020.
"The agreed changes will be completed in time for the commencement of the 2019 to 2020 financial year."
