Residents in Falkirk Council area currently have three bins – green for general waste, blue for recyclables, brown for garden waste, a black box for glass and a food caddy.
But in a bid to reach recycling targets, the local authority is again considering options.
Councillor Paul Garner outlined his idea for a box to collect metals, plastics and cartons, the blue bin for paper and card and the green bin for non-recyclable waste, all to be uplifted monthly.
Another box for glass and textiles and a brown bin for garden and food waste would be collected fortnightly.
Mr Garner said: “Other local authorities have a joint food and garden waste bin. The residents will have the same containers as before which must be of very high quality material.”
Rhona Geisler, director of development services, said:
“We need to agree the proposed recycling method so we can submit our funding application to Zero Waste Management Scotland.”
Councillors decided further meetings will be held before a final decision is made.
