THOUSANDS of people in parts of Huddersfield are facing moves to cut their weekly refuse collections.
The reductions are due to be tried out in Almondbury, Lepton and Dalton.
Waste chiefs are aiming to encourage more people to recycle and to drive down the costs of disposal at landfill sites.
Grey bin collections will be changed from weekly to fortnightly.
But green recycling bins would be emptied more often in a bid to get people to put more in them.
Green pick-ups would be made every two weeks instead of monthly.
Clr Ann Denham, Kirklees Council Cabinet member for the environment, said: "An issue that is regularly raised with me and many councillors is that the monthly emptying of green bins of recycled materials is not often enough.
"A lot of people fill their green bins within a fortnight or three weeks and then have to put recycled materials in the general grey waste bin.
"That means a lot of waste suitable for recycling gets put in the general waste."
The pilot scheme will discover if more material is recycled when green collections are increased."
Clr Denham added: "The only way we can find out is by trying it out."
A decision on whether to go ahead with the trials is due to be made by a Cabinet committee next Wednesday.
At the same time, a glass collection scheme will be expanded to a further 22,000 properties across Kirklees.
There will be increased promotion of home composting including Government subsidised home compost bins.
A new free `woody' waste collection scheme will start for prunings, twigs and branches.
It will operate from June to complement an existing free garden waste collection service.
Garden waste will be banned from grey bins.
Potential schemes for recycling trade waste will be explored. Glass recycling for a limited number of commercial premises will be piloted.
Clr Denham said: "I find it very heartening how enthusiastic the vast majority of people are to the recycling concept.
"The package of measures proposed intends to build on that success and test out some new ideas."
