Key Points
- This is set to be done in more than 21,000 homes in selected parts of Whitchurch/Tongwynlais, Grangetown, Trowbridge, and Rhiwbina areas in the Cardiff region.
- Residents of these selected locations will be supplied with red plastic bags as well as information leaflets starting from September 28, and the project will be formally rolled out from October 13, 2026.
- This is in anticipation of a mandatory statutory requirement by the Welsh Government for all councils to offer kerbside collection services for soft plastics by April 2027.
- The accepted materials will include flexible and lightweight plastics, such as crisp packets, carrier bags, bread bags, cling films, and bubble wrap, but not items like food pouches, polystyrene, and food waste.
- According to data from The Waste and Resources Action Programme (WRAP) Cymru, Cardiff recycled 64% of its waste in 2024/25, which placed it below the UK national average of 68%.
- The council believes the recycling rate of the city will increase from 0.4% to 1.6%, depending on the quantity of soft plastic recovered in the process (3,000 tonnes).
Cardiff (Cardiff Daily) September 23, 2026 — Thousands of households across the Welsh capital are set to trial a dedicated kerbside collection scheme for soft plastics, introducing a specialized red bag system to target flexible packaging materials commonly found in general household waste. As reported by Kieran Molloy of Herald.Wales and Wales Online, the initiative involves approximately 21,000 properties across specific parts of Whitchurch/Tongwynlais, Grangetown, Trowbridge, and Rhiwbina. Households included in the trial area will receive informational leaflets and introductory rolls of red plastic bags beginning September 28, ahead of the official pilot launch on October 13. The scheme is designed to address plastic film, wrapping, and bags that have historically contributed significantly to residual black bin waste.
Which Cardiff Postcodes and Areas Are Included in the Soft Plastic Trial?
The pilot scheme targets roughly 21,000 properties situated within specific sectors of the Welsh capital. According to details published by Rhys Gregory of Wales247, residents living within designated parts of the Whitchurch/Tongwynlais, Grangetown, Trowbridge, and Rhiwbina wards can expect to take part in the initial phase.
As noted in coverage by Kieran Molloy of Wales Online, the affected properties primarily fall under postcode districts CF14, CF3, and CF11. Residents uncertain about their inclusion status have been advised by Cardiff Council to verify their addresses via an online checker hosted on the local authority’s official website. For households selected for the trial, rolls of red recycling bags will be delivered directly, with provisions to order additional supplies online. Specialized recycling officers will also be deployed to provide guidance and assistance to participating residents.

What Items Are Accepted or Prohibited in the New Red Bags?
The trial establishes strict guidelines regarding which materials qualify for the soft plastic recycling stream. As outlined by Kieran Molloy of Herald.Wales, the service accepts clean, flexible lightweight packaging including carrier bags, bread bags, crisp packets, biscuit wrappers, frozen food bags, pasta and rice bags, cereal box liners, sweet and chocolate wrappers, plastic delivery bags, ready-packed fruit and vegetable bags, cling film, and bubble wrap. All submitted items must remain strictly free from food residue and liquids.
Conversely, several items are explicitly banned from the red bags. Prohibited materials include polystyrene, food and pet food pouches, fruit and vegetable netting, plastic straws and cutlery, disposable gloves and masks, batteries, vapes, e-cigarettes, and general food waste. Rigid plastics must continue to be placed in standard red recycling sacks. Furthermore, Cardiff Council instructs residents to place soft plastics loosely inside the red bags rather than stuffing them inside secondary bags or tying them together, ensuring sorting facilities can process the materials efficiently.
Why Is Cardiff Council Launching This Recycling Initiative Now?
The rollout arrives in direct response to upcoming environmental mandates set by the devolved government. As detailed by Kieran Molloy of Herald.Wales, the Welsh Government has instituted a statutory requirement demanding that all local authorities implement kerbside collections for soft plastics no later than April 2027. Cardiff Council’s cabinet agreed in March 2026 to advance preparations through this targeted pilot.
Statistical insights from The Waste and Resources Action Programme (WRAP) Cymru indicate that Cardiff achieved a recycling rate of 64% during the 2024–25 period. While demonstrating strong civic participation, this figure remains below the broader national average of 68% and marks the third-lowest performance across Welsh local authorities for that specific year, trailing only Flintshire at 63% and Caerphilly at 62%. WRAP data further shows that approximately 63% of materials entering Cardiff’s black bins and general waste bags are theoretically recyclable, with plastic bags and wrapping accounting for nearly 6% of that residual volume.
Addressing the strategic objectives of the project, Cllr Ed Stubbs, the council’s cabinet member for frontline services, stated as reported by Kieran Molloy of Herald.Wales:
“Residents already do an excellent job recycling, helping the city achieve its current recycling rate of 64%, but we know we can do even better.”
Cllr Stubbs further emphasized the broader environmental benefits to Herald.Wales, stating:
“This new service will make it easier for people to recycle more of their waste from home, helping us further reduce the amount of waste placed in black bins and bags. Plastic bags and wrapping are among the most common items found in general waste. By collecting these materials separately and recycling them into new products we can reduce waste, cut carbon emissions, and help keep Wales among the best recycling nations in the world.”
Elaborating on projected metrics in coverage by Rhys Gregory of Wales247, Cllr Stubbs noted:
“Although participation and material capture rates will vary, we estimate that the scheme could increase the recycling rate by between 0.4% and 0.7%, making an important contribution to our recycling ambitions.”
Overall estimates suggest that successfully capturing the estimated 3,000 tonnes of soft plastic circulating within Cardiff’s waste stream could eventually push total city recycling yields up by as much as 1.6%.
What Are the Expectations Based on Previous Regional Trials?
Local authorities are utilizing data gathered from neighboring Welsh regions to gauge likely outcomes for the Cardiff pilot. Cllr Ed Stubbs highlighted to Herald.Wales and Wales Online that comparable trials conducted in Swansea and the Vale of Glamorgan yielded an average resident participation rate of 61%, alongside a 98% positive approval rating among surveyed participants. Council administrators anticipate mirroring these positive metrics within the Welsh capital to drive structural improvements in local waste management performance.
Following the conclusion and evaluation of the initial pilot phase across the 21,000 trial households, Cardiff Council plans to scale up the infrastructure. A comprehensive city-wide rollout across all remaining residential wards is scheduled to take place next year. Until the service expands to their specific neighborhoods, residents without access to the pilot are encouraged to utilize existing supermarket soft plastic recycling drop-off points or continue standard disposal methods.
Background of the Development
The introduction of kerbside soft plastic collections in Cardiff represents a significant operational shift driven by tightening statutory mandates across Wales. For years, flexible plastics—such as crisp packets, bread bags, and film wrappings—posed a major challenge for municipal recycling streams because traditional sorting facilities were unequipped to process lightweight films without jamming mechanical separators. Consequently, these materials were routinely relegated to general landfill or incineration streams, dragging down municipal recycling metrics.
To combat this, the Welsh Government established ambitious environmental targets under its “Beyond Recycling” strategy, aiming for zero waste by 2050 and positioning Wales as a global leader in circular economy practices. Regulatory pressure intensified as WRAP Cymru and environmental watchdogs pointed out stagnation in certain urban recycling rates. By setting a hard deadline of April 2027 for all Welsh local authorities to collect soft plastics directly from households, the Welsh Government forced councils to transition experimental supermarket drop-off models into formal kerbside logistics. Cardiff Council’s October 2026 pilot serves as a necessary testing ground to resolve collection logistics, public sorting compliance, and processing capabilities ahead of the mandatory nationwide enforcement date.
The rollout of the soft plastic recycling trial is poised to create multi-layered operational and behavioral changes for Cardiff residents and local administrative bodies. For the approximately 21,000 households participating in Whitchurch/Tongwynlais, Grangetown, Trowbridge, and Rhiwbina, the inclusion of an eighth container element—the red soft plastic bag—demands heightened household waste segregation habits. While initial public engagement in regions like Swansea and the Vale of Glamorgan proved largely favorable, the complexity of identifying acceptable versus prohibited flexible plastics (such as distinguishing crisp wrappers from food pouches) risks causing contamination in the early stages.
Over the medium term, as the scheme expands city-wide in the following year, residents will likely experience a noticeable reduction in their general black bag waste volume, aligning with municipal goals to cut down residual refuse. However, this transition will also increase accountability for households; given that Cardiff enforces strict waste rules—including potential fines of up to £150 for incorrect recycling practices—residents must carefully adhere to sorting criteria to avoid penalties. Ultimately, the development will bridge the gap between local domestic routines and national environmental metrics, steering Cardiff closer to compliance with the Welsh Government’s stringent 2027 recycling directives while altering how everyday packaging is handled at the curb.
