Norfolk County Council is seeking to let contracts for waste treatment and waste transfer station services for the period to 2020.
This follows a row over a planned incinerator, above, which it dropped last year.
The council has offered a contract of between £40m and £100m for treatment and disposal services for some 160,000 tonnes a year of residual waste.
The other tender, valued between £8m and £45m, is for a framework agreement for waste transfer station services in or near Norfolk, for the reception, handling and storage of some 127,500 tonnes of residual waste.
The county also sends 40,000 tonnes of waste a year to neighbouring Suffolk County Council’s energy-from-waste plant, and that deal has been extended to 2020.
A Norfolk spokesman told MRW that councillors would seek a long-term solution beyond 2020, with consultation on this due next year.
“The guiding principle is to find a more sustainable solution than dumping our leftover rubbish in landfill and which is acceptable to Norfolk residents,” the council said.
