Maulana Noriandita/ShutterstockThe government has recently introduced simpler rules on recycling in England, planning to end the confusion of different types of waste being collected in different postcodes. Scotland and Northern Ireland already operate (or are updating) their own devolved recycling laws that are equivalent to England’s simpler recycling system.This should also mean the widespread introduction of weekly food waste collections across England and more separation of waste overall. But at the same time, there’s still some public concern about the main “black bin” rubbish collection shifting away from weekly to more infrequent pickups.For instance in Northampton, Thanet and South Gloucestershire, residents have recently been protesting over the frequency of their waste collections as well as over confusing changes, bins not being delivered and waste collections not happening on time. Meanwhile, in Australia, a recent switch by a local council from weekly to fortnightly waste collection attracted criticism from some local residents.Does the shift work?Many people across the UK now get their dustbins emptied every two weeks. In some cases the recycling bin is also emptied every two weeks. This is not a cost-cutting gimmick, there’s plenty of evidence that our black bins do not need to be collected every week, and that cutting pickups can result in reduced waste. This shift to fortnightly collections began through pilot schemes more than 20 years ago. Councils in the UK tested alternate weekly collections in the 2000s. Early research showed people recycle more when services are simple and reliable. Well-designed containers, easy kerbside access and predictable routines drive participation.Social, cultural and structural factors also shape household recycling behaviour. For instance, if a neighbour recycles regularly this can influence a householder to do the same. Households recycle more and divert more waste from landfill when systems include food caddies.Targeted service design, including tailoring bin types and sizes, collection schedules, instructions, as well as support where recycling is more difficult (such as in flats), drives higher recycling.Fortnightly bin collections have reduced amounts of waste when paired with weekly food-waste collection and better recycling. It also lowered greenhouse-gas emissions. Fortnightly “black bin” pickups steer waste prevention and recycling, while weekly food-waste captures organics, cutting landfill methane. Reducing wasteOver the years councils have tried out changes in rubbish pickups. They added weekly food-waste bins. They expanded recycling. They ran targeted campaigns for flats and vulnerable households. Independent evaluations of pilot schemes showed consistent results: recycling rose, residual waste fell, and costs dropped.Wales is now second in the world for recycling (behind Austria), with levels around 68%, a global benchmark achieved through consistent collection policy and investment in household services. Scotland comes in at 15th, and England is in 11th position.Local councils can now point to authoritative research to help make their arguments for change. They can also show savings and emissions reductions. Across the whole UK, I estimate that 289-294 councils (out of 360), including at least 27 (out of 32) councils in Scotland, now collect residual waste fortnightly and recycling on alternating weeks. This approach is now used by growing numbers of authorities.Cutting costsBy the mid-2020s, more than 80% of English councils had moved to fortnightly or longer residual cycles, with only a minority retaining weekly refuse rounds. These success stories are widely cited in policy reviews. What worked in the UK can be summarised in four ways. 1. Keep food waste weekly. Food is the main source of odour and contamination. Weekly food waste collection removes the biggest barrier to less frequent residual pickup. 2. Expand recycling streams. Offer clear, separate containers for paper, card, glass, plastics and metals. Make recycling easier than throwing things away. 3. Support flats and vulnerable households. Doorstep services must be adapted. Communal bins need management. Extra help must be available for those who cannot manage new routines. 4. Test and communicate. Phase in trials, tell people how much is being recycled and keep in touch with the public. These will build trust. People accept change when they see evidence and feel heard. Cities worldwide face the same pressures: tight budgets, climate targets and the need to divert waste from landfill and incineration. The global stakes are high. Waste systems account for a meaningful share of municipal budgets and of urban greenhouse-gas emissions. Small changes in collection design scale quickly. Rubbish collections are changing across England. Lessons from good policyThe UK experience offers practical lessons for other nations. The shift was not inevitable, but it has delivered three outcomes every city, town or village wants: cost savings, higher recycling and lower emissions. It frees up money for reuse schemes, repair hubs and sorting out infrastructure. It nudges households toward wasting less. The UK story matters beyond its borders. Cities from Miyazaki, Japan, to Montreal, Canada, and Melbourne, Australia, have been learning from the evidence. This is more than a bin schedule. It is a policy that reduces waste, lowers emissions and saves public money when paired with strong recycling services. The UK’s evidence-led rollout has created a template that other nations now test. Done right, fortnightly collections reduce waste, save money, cut emissions and change throwaway habits. Done wrong, they inflame communities. Drawing on two decades of experience this evidence shows how careful design and phased trials turned a technical service change into mainstream policy from Wales to Canada, and why other cities should treat collection design as a strategic lever rather than a political shortcut. This comes at a time when many local councils face renewed budget pressures and legally binding net-zero targets.The UK’s experience provides timely, evidence-based options for cities worldwide to help them cut costs. By following the evidence, decision-makers can avoid the pitfalls that inflame communities and instead replicate the safeguards that have delivered measurable benefits.Ian Williams receives funding from UK Research Councils, including the Engineering and Physical Sciences Research Council’s Impact Acceleration Account.
