The addition of new materials to recycling habits in Highland could save the council around £70,000.
From next year, items such as tetrapaks and aerosol containers can be included in blue bins, which are currently used to collect paper, cardboard and tins.
It is part of a Highland Council plan to increase the amount of recyclate to 75% of total waste.
The authority carried out a waste composition analysis in June this year and found that around 43% of household waste is collected through green bins and 20% through kerbside recycling.
The remaining 37% is captured through recycling centres and points and residual waste skips.
The council have said that a further 2,700 tonnes of material, including glass, paper, card, metals and plastic bottles, could be diverted from landfill.
Chairman of the community services committee, Councillor Graham Mackenzie appealed to the public to increase their efforts to use recycling facilities.
He said “Everyone can help to recycle more. This will not only save money in landfill costs, but is a much better thing to do for our environment and our future.”
