A Welsh local authority has started trialling four-weekly residual waste collections.
Conwy Borough Council is rolling out the scheme across around 10,000 properties in the area, all of which have Monday collections.
All other properties in the area, currently on fortnightly collections, will move to a permanent three-weekly schedule.
The rollout of the scheme is staged but some received their last fortnightly collection on 3 September, with their first four-weekly collection due on 3 October.
All recycling services in the region will stay the same, including weekly dry recycling and food waste collections.
Electrical and textile waste is collected each fortnight while a nappy collection service will be available on registration.
Councillor Dave Cowans said: “This is a great opportunity for residents to review their recycling habits, and make sure that everything that can be recycled is being recycled.
“In Conwy, more than half of an average household wheelie bin is incorrectly filled with recycling and food waste, which is collected separately every week.”
Conwy’s cabinet decided to change its bin schedule in February following a year-long review of householders’ recycling and waste habits. The review found that over half the items placed into wheelie bins could have been recycled, which the council says causes a waste of £1.6m a year.
It expects the changes to boost its recycling rate, which has plateaued at 59%.
Welsh authorities have been given a 64% recycling target by 2019-20, rising to 70% by 2024-25. They face stiff penalties if targets are missed.
At least three other Welsh councils – Bridgend, Torfaen and Ceredigion – have mooted four-weekly collections.
Most of the 22 Welsh councils undertake fortnightly residual collections. Blaenau Gwent, Powys and Gwenedd have implemented three-weekly collections for all or selected areas.
