GREATER education is needed before a pioneering rubbish recycling system is extended to other parts of Kirklees, says a councillor.
A pilot scheme in Almondbury, Lepton, Moldgreen and Dalton sees grey bins emptied one week and green bins the next, with glass collected once a month from a 40-litre box.
In the rest of the district general rubbish is collected weekly and recyclable waste monthly.
Kirklees Council plans to expand the new system to Batley, Dewsbury, Mirfield, Spen and Heckmondwike later this year.
But Lib Dem councillor Ann Denham , who represents the Almondbury ward, thinks more of an educational effort will be needed in these places.
She said: "There are going to be more problems in North Kirklees than there were in the trial areas.
"There's a wider cross-section of the community in the north, with more areas that are poor.
"It will be more difficult to get the recycling message across."
North Kirklees is due to switch to the new system in stages between June and November, with information packs sent out before.
Denby Dale and Kirkburton will switch to the new system next February, with the rest of south Kirklees joining in later that year.
Meanwhile, new figures from the 5,500 homes in the trial areas show that 60% of people found the less frequent grey bin collection easy to adapt to, with only 25% saying it had been difficult.
