Caerphilly’s recycling rates are now the lowest in Wales, according to new figures.

The county borough’s performance slipped to recycling 60.1 per cent of all waste in 2023, down from 60.7 per cent the year before.

Caerphilly Council is considering four-weekly bin collections as one way to encourage people to recycle more.

Welsh Government figures show the council’s rates have generally fallen steadily over the past seven years and now languish well below national targets.

Any councils which fail to meet minimum performance rates are liable to hefty fines, as the government seeks to maintain Wales as one of the world’s best-performing recycling nations.

Until April, the recycling rate required to avoid those penalties is 64 per cent, and the worrying issue in Caerphilly is that its performance is heading in the wrong direction.

The council was comfortably beating that 64 per cent figure until 2019, when rates started to dip below the target – and have yet to recover.

This year, the government hiked its target rate to 70 per cent, piling pressure on councils to recycle even more of the waste they collect.

But even if the old target had stayed in place, Caerphilly Council’s latest sub-par recycling rates would leave it open to fines, mooted last year by senior councillors to be as much as £2 million annually.

The council last year announced a new draft waste strategy designed to drive up its recycling rates, and a three-month public consultation on those plans closed this April.

Possible actions include new containers for residents to separate recyclable materials and four-weekly collections of non-recyclable waste.

That is in addition to a series of “quick wins” the council announced midway through 2023, including a trial of free food caddy liners to encourage people to stop throwing their leftovers and vegetable peelings in the bin.

Until then, Caerphilly was an outlier in not providing that service for residents.

The council has also announced tighter rules on what people can throw away at its tips, or so-called household recycling centres.

Around half of what was being dumped at the county borough’s tips could have been recycled, the local authority said at the time.

Since February, residents have been required to pre-sort their waste before arriving at a tip, where bags of waste are also being “monitored” by staff to make sure “no recyclable materials are inside”.

A controversial plan to bring in a booking system at Caerphilly’s tips was axed from the waste strategy consultation, however, after some councillors said it could lead to more fly-tipping.

Caerphilly Council was approached for comment on the latest recycling performance figures.
