Having wasted over forty years of my life in waste management, I feel broadly qualified, emotionally, operationally and possibly medically to say that when it comes to recycling, the less that’s left to the public, the better.
This is not an attack on people. People are generally well meaning, decent and keen to do the right thing. The problem is that they are also, when faced with a recycling bin, catastrophically unreliable.
The Recycling Station Thought Experiment;
Give the public a recycling station with a forty-foot image of a paper cup, and the words “PAPER CUP RECYCLING” in letters large enough to be seen from space, then stand back and within minutes you'll observe Coca-Cola cans, Evian plastic bottles and napkins that belong elsewhere being rammed in smugly, the depositor walking away quietly chuffed that they’ve just saved a small part of the planet thinking 'That’s my bit done'.
What they’ve actually done is contaminate the stream, increase processing costs and quietly sabotage the very system they believe they’re helping.
Over the years I have personally encountered rocks (actual lumps of stone) in confidential waste paper sacks; dog sh*t in paper and cardboard bins, banana skins in WEEE containers, greasy napkins, half-eaten chicken and biological mysteries in dry mixed recycling - at which point one is tempted to confront the perpetrator and ask 'What, exactly did you imagine we’d recycle this into'?
The public is not malicious, it's just hard-wired to contaminate recycling - not out of spite but because rules are complex, packaging lies, labels are inconsistent and wish-cycling feels virtuous. The greatest myth in modern waste policy is that better behaviour will fix a badly designed system. Shocker - it won’t.
The government, Defra and councils alike prefer to believe recycling fails because the public isn’t trying hard enough. That belief is comforting as it implies the system is sound and only the users are faulty. In reality, we’ve built a system that requires every household to behave like a trained materials technician while deliberately flooding the market with packaging that even professionals struggle to identify. That isn’t behaviour change, it’s abdication.
Do the Heavy Lifting Where It Belongs
The solution is not more posters, not friendlier icons, not interpretive recycling dance routines. The solution is to take the burden off the public entirely. Modern waste systems succeed when the intelligence sits infrastructure-side, not kerbside.
That means:
Robotic pickers don’t get bored, optimistic, pessimistic or distracted. These systems do not guess, improvise or feel proud. They simply sort correctly, relentlessly and without interpreters.
Countries that outperform the UK on recycling do not do so because their citizens are more virtuous. They do it better because the state intervenes upstream, not downstream.
Germany’s success is built on regulatory intolerance: strict producer obligations, fewer permitted materials, high landfill and incineration penalties and deposit systems that hurt if ignored. Compliance follows because ambiguity is designed out.
Japan assumes confusion is inevitable so it eliminates discretion. Standardised packaging, mandatory disassembly and legal responsibility sitting squarely with producers mean recycling works because non-compliance is socially and legally expensive.
South Korea didn’t ask people nicely to waste less food. It charged them for it, tracked it digitally, and enforced it, turning behaviour change into a by-product of system design.
Norway’s deposit return scheme works because it is simple, unavoidable and financially motivating. Return rates exceed 90% not because Norwegians care more but because the system removes the option not to comply.
The Netherlands assumes contamination will happen then engineers around it. High-tech facilities, aggressive material bans and minimal reliance on household perfection mean the public participates while the infrastructure performs.
Where This Leaves Britain
The UK is not hopeless but it remains politely conflicted - the UK government is reluctant to ban, nervous about enforcement, obsessed with nudging behaviour and terrified of upsetting producers. We ask households to compensate for poor packaging decisions made far upstream then act surprised when contamination follows. That's not the public's fault, it's governmental policy cowardice.
Traceability: The Real Prize
Things are, quietly, beginning to move. With digital packaging identification systems emerging and operational R&D being carried out by major waste operators, we are edging toward cradle to grave packaging identification, verified material flows and real funding entering the system. The vast majority of that money will land at council level where it will be least wisely spent but some of it will filter through into Simpler Recycling compliance, MRF upgrades, and expanded sorting capability which is where it actually matters.
Design for Contamination
Good waste systems don’t assume perfect behaviour; they assume distraction, confusion, laziness, optimism and the occasional act of bin-based nihilism; then they engineer around it. If your recycling system collapses because someone put a banana in the wrong bin, it was never robust in the first place.
My Final Thought
Recycling succeeds despite human behaviour, not because of it so let's stop blaming the public; stop pretending signage will save us and start building systems that assume correctly that someone, somewhere will always put the wrong thing in the wrong bin.
