Highland Council is to restrict the amount of construction and demolition waste brought to its household waste recycling centres from November.
At the same time, the council’s bulky uplift service will be expanded to include small amounts of DIY material.
The move will save £300,000 over two years, the council says.
Only waste generated through minor DIY activities will now be accepted at the recycling centres.
Much of the additional waste at recycling centres is construction and demolition waste such as rubble, plasterboard, timber, old kitchen units and bathroom suites.
The council has no statutory duty to accept this kind of waste.
Under the changes, trailers over 7ft 8inches (2.4metres), vans over 3.5 tonnes, tippers and trucks will not be permitted at any Highland recycling centre with any waste.
Householders will be allowed to bring small quantities of construction and demolition waste but this will be restricted to what can be transported in the boot of a car and householders will be limited to one visit one visit per day with this material.
These restrictions will not apply to normal household waste such as furniture, white goods and garden waste.
A number of items previously excluded will now be permitted.
They include bathroom suites and sanitary ware, bicycles, car wheels and tyres, doors, kitchen units, lawnmowers and garden tools and window frames.
A maximum of six items can be collected, with charges ranging from £22.69 to £45.37.
Councillor Allan Henderson said: “These new measures will help to ensure that the commercial and trade waste producers are not taking advantage of the services we offer members of the public at our network of recycling centres.
“If anyone is using a commercial company or a tradesman to carry out DIY jobs for them, they need to make sure that arrangements are in place for materials to be disposed of correctly.”
