A councillor says he wants to question colleagues about a £1.6m order of blue recycling bins for Stoke-on Trent.
British National Party councillor Mike Coleman said he wanted the purchase to be explained as an independent advisory group suggested a different option.
The Waste and Resources Action Programme (Wrap) advises the government and councils on how to meet targets.
The audit committee will meet in the new year and it would be inappropriate to comment now, the council said.
Wrap suggested residents separate their rubbish into eight different bins, bags and boxes as the best way to meet government recycling targets.
But the authority said it still met its recycling target for 2010 and was on course to meet its target for 2015 using the blue bin option, which involves mixing food with garden waste and cardboard.
Speaking ahead of a council meeting about the issue on Wednesday morning, Mr Coleman said he wanted to question colleagues.
"I want that meeting to be deferred into the new year when I'm going to be using my powers and instructing officers of the council to come before that committee," he said.
The council is run by a Labour-led coalition made up of Conservatives and Independent Alliance, Liberal Democrats and the City Independent Group.
