Solihull Council has pulled out of plans to build a £1 billion private finance initiative waste incinerator in the West Midlands.
Councillors have unanimously backed a report recommending the authority explore other options for the future of non-recyclable waste residue in the borough, instead of continuing with plans for Project Transform.
The scheme would have seen an existing burner at Whitley in Coventry replaced with a new incinerator serving Solihull, Warwickshire and Coventry.
The decision was taken after an engineering report submitted last month showed that the current incinerator could last for at least another 30 years.
Earlier this year it emerged the councils had spent £1.73 million on the project.
